Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
|
||||
Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
|
||||
|
||||
In addition to negotiator, it allows:
|
||||
|
||||
- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
|
||||
as well as `('text/html', 'application/json')`.
|
||||
- Allows type shorthands such as `json`.
|
||||
- Returns `false` when no types match
|
||||
- Treats non-existent headers as `*`
|
||||
|
||||
## Installation
|
||||
|
||||
This is a [Node.js](https://nodejs.org/en/) module available through the
|
||||
[npm registry](https://www.npmjs.com/). Installation is done using the
|
||||
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
|
||||
|
||||
```sh
|
||||
$ npm install accepts
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
```js
|
||||
var accepts = require('accepts')
|
||||
```
|
||||
|
||||
### accepts(req)
|
||||
|
||||
Create a new `Accepts` object for the given `req`.
|
||||
|
||||
#### .charset(charsets)
|
||||
|
||||
Return the first accepted charset. If nothing in `charsets` is accepted,
|
||||
then `false` is returned.
|
||||
|
||||
#### .charsets()
|
||||
|
||||
Return the charsets that the request accepts, in the order of the client's
|
||||
preference (most preferred first).
|
||||
|
||||
#### .encoding(encodings)
|
||||
|
||||
Return the first accepted encoding. If nothing in `encodings` is accepted,
|
||||
then `false` is returned.
|
||||
|
||||
#### .encodings()
|
||||
|
||||
Return the encodings that the request accepts, in the order of the client's
|
||||
preference (most preferred first).
|
||||
|
||||
#### .language(languages)
|
||||
|
||||
Return the first accepted language. If nothing in `languages` is accepted,
|
||||
then `false` is returned.
|
||||
|
||||
#### .languages()
|
||||
|
||||
Return the languages that the request accepts, in the order of the client's
|
||||
preference (most preferred first).
|
||||
|
||||
#### .type(types)
|
||||
|
||||
Return the first accepted type (and it is returned as the same text as what
|
||||
appears in the `types` array). If nothing in `types` is accepted, then `false`
|
||||
is returned.
|
||||
|
||||
The `types` array can contain full MIME types or file extensions. Any value
|
||||
that is not a full MIME type is passed to `require('mime-types').lookup`.
|
||||
|
||||
#### .types()
|
||||
|
||||
Return the types that the request accepts, in the order of the client's
|
||||
preference (most preferred first).
|
||||
|
||||
## Examples
|
||||
|
||||
### Simple type negotiation
|
||||
|
||||
This simple example shows how to use `accepts` to return a different typed
|
||||
respond body based on what the client wants to accept. The server lists it's
|
||||
preferences in order and will get back the best match between the client and
|
||||
server.
|
||||
|
||||
```js
|
||||
var accepts = require('accepts')
|
||||
var http = require('http')
|
||||
|
||||
function app (req, res) {
|
||||
var accept = accepts(req)
|

|

AsyncKit provides harness for `parallel` and `serial` iterators over list of items represented by arrays or objects.
|
||||
Optionally it accepts abort function (should be synchronously return by iterator for each item), and terminates left over jobs upon an error event. For specific iteration order built-in (`ascending` and `descending`) and custom sort helpers also supported, via `asynckit.serialOrdered` method.
|
||||
|
||||
It ensures async operations to keep behavior more stable and prevent `Maximum call stack size exceeded` errors, from sync iterators.

## Install
|
||||
|
||||
```sh
|
||||
$ npm install --save asynckit
|
||||
```
|
||||
|
||||
## Examples
|
||||
|
||||
### Parallel Jobs
|
||||
|
||||
Runs iterator over provided array in parallel. Stores output in the `result` array,
|
||||
on the matching positions. In unlikely event of an error from one of the jobs,
|
||||
will terminate rest of the active jobs (if abort function is provided)
|
||||
and return error along with salvaged data to the main callback function.
|
||||
|
||||
#### Input Array
|
||||
|
||||
```javascript
|
||||
var parallel = require('asynckit').parallel
|
||||
, assert = require('assert')
|
||||
;
|
||||
|
||||
var source = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
|
||||
, expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
|
||||
, expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
|
||||
, target = []
|
||||
;
|
||||
|
||||
parallel(source, asyncJob, function(err, result)
|
||||
{
|
||||
assert.deepEqual(result, expectedResult);
|
||||
assert.deepEqual(target, expectedTarget);
|
||||
});
|
||||
|
||||
// async job accepts one element from the array
|
||||
// and a callback function
|
||||
function asyncJob(item, cb)
|
||||
{
|
||||
// different delays (in ms) per item
|
||||
var delay = item * 25;
|
||||
|
||||
// pretend different jobs take different time to finish
|
||||
// and not in consequential order
|
||||
var timeoutId = setTimeout(function() {
|
||||
target.push(item);
|
||||
cb(null, item * 2);
|
||||
}, delay);
|
||||
|
||||
// allow to cancel "leftover" jobs upon error
|
||||
// return function, invoking of which will abort this job
|
||||
return clearTimeout.bind(null, timeoutId);
|
||||
}
|
||||
```
|
||||
|
||||
More examples could be found in [test/test-parallel-array.js](test/test-parallel-array.js).
|
||||
|
||||
#### Input Object
|
||||
|
||||
Also it supports named jobs, listed via object.
|
||||
|
||||
```javascript
|
||||
var parallel = require('asynckit/parallel')
|
||||
, assert = require('assert')
|
||||
;
|
||||
|
||||
var source = { first: 1, one: 1, four: 4, sixteen: 16, sixtyFour: 64, thirtyTwo: 32, eight: 8, two: 2 }
|
||||
, expectedResult = { first: 2, one: 2, four: 8, sixteen: 32, sixtyFour: 128, thirtyTwo: 64, eight: 16, two: 4 }
|
||||
, expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
|
||||
, expectedKeys = [ 'first', 'one', 'two', 'four', 'eight', 'sixteen', 'thirtyTwo', 'sixtyFour' ]
|
||||
, target = []
|
||||
, keys = []
|
||||
;
|
||||
|
||||
parallel(source, asyncJob, function(err, result)
|
||||
{
|
||||
assert.deepEqual(result, expectedResult);
|
||||
assert.deepEqual(target, expectedTarget);
|
||||
assert.deepEqual(keys, expectedKeys);
|
||||
});
|
||||
|
||||
// supports full value, key, callback (shortcut) interface
|
||||
function asyncJob(item, key, cb)
|
||||
{
|
||||
// different delays (in ms) per item
|
||||
var delay = item * 25;
|
||||
|
||||
// pretend different jobs take different time to finish
|
||||
// and not in consequential order
|
||||
var timeoutId = setTimeout(function() {
|
||||
keys.push(key);
|
||||
target.push(item);
|
||||
cb(null, item * 2);
|
||||
}, delay);
|
||||
|
||||
// allow to cancel "leftover" jobs upon error
|
||||
// return function, invoking of which will abort this job
|
||||
return clearTimeout.bind(null, timeoutId);
|
||||
}
|
||||
```
|
||||
|
||||
More examples could be found in [test/test-parallel-object.js](test/test-parallel-object.js).
|
||||
|
||||
### Serial Jobs
|
||||
|
||||
Runs iterator over provided array sequentially. Stores output in the `result` array,
|
||||
on the matching positions. In unlikely event of an error from one of the jobs,
|
||||
will not proceed to the rest of the items in the list
|
||||
and return error along with salvaged data to the main callback function.
|
||||
|
||||
#### Input Array
|
||||
|
||||
```javascript
|
||||
var serial = require('asynckit/serial')
|
||||
, assert = require('assert')
|
||||
;
|
||||
|
||||
var source = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
|
||||
, expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
|
||||
, expectedTarget = [ 0, 1, 2, 3, 4, 5, 6, 7 ]
|
||||
, target = []
|
||||
;
|
||||
|
||||
serial(source, asyncJob, function(err, result)
|
||||
{
|
||||
assert.deepEqual(result, expectedResult);
|
||||
assert.deepEqual(target, expectedTarget);
|
||||
});
|
||||
|
||||
// extended interface (item, key, callback)
|
||||
// also supported for arrays

#### Input Object
|

|

Also it supports named jobs, listed via object.

```javascript
|

var serial = require('asynckit').serial
|
||||
, assert = require('assert')
|
||||
;
|
||||
|
||||
var source = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
|
||||
, expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
|
||||
, expectedTarget = [ 0, 1, 2, 3, 4, 5, 6, 7 ]
|
||||
, target = []
|

;
|

|

|

|
||||
, target = []
|
||||
;
|
||||
|
||||
|
||||
serial(source, asyncJob, function(err, result)
|
||||
{
|
||||
assert.deepEqual(result, expectedResult);
|
||||
assert.deepEqual(target, expectedTarget);
|
||||
});
|
||||
|
||||
// shortcut interface (item, callback)
|
||||
// works for object as well as for the arrays
|
||||
function asyncJob(item, cb)
|
||||
{
|
||||
target.push(item);
|
||||
|
||||
// it will be automatically made async
|
||||
// even it iterator "returns" in the same event loop
|
||||
cb(null, item * 2);
|
||||
}
|
||||
```
|
||||
|
||||
More examples could be found in [test/test-serial-object.js](test/test-serial-object.js).
|
||||
|
||||
_Note: Since _object_ is an _unordered_ collection of properties,
|
||||
it may produce unexpected results with sequential iterations.
|
||||
Whenever order of the jobs' execution is important please use `serialOrdered` method._
|
||||
|
||||
### Ordered Serial Iterations
|
||||
|
||||
TBD
|
||||
|
||||
For example [compare-property](compare-property) package.
|
||||
|
||||
### Streaming interface
|
||||
|
||||
TBD
|
||||

<br />
|
||||
|
||||
## Features
|
||||
|
||||
- Integers and decimals
|
||||
- Simple API but full-featured
|
||||
- Faster, smaller, and perhaps easier to use than JavaScript versions of Java's BigDecimal
|
||||
- 8 KB minified and gzipped
|
||||
- Replicates the `toExponential`, `toFixed`, `toPrecision` and `toString` methods of JavaScript's Number type
|
||||
- Includes a `toFraction` and a correctly-rounded `squareRoot` method
|
||||
- Supports cryptographically-secure pseudo-random number generation
|
||||
- No dependencies
|
||||
- Wide platform compatibility: uses JavaScript 1.5 (ECMAScript 3) features only
|
||||
- Comprehensive [documentation](http://mikemcl.github.io/bignumber.js/) and test set
|
||||
|
||||
|
||||
|
||||
If a smaller and simpler library is required see [big.js](https://github.com/MikeMcl/big.js/).
|
||||
It's less than half the size but only works with decimal numbers and only has half the methods.
|
||||
It also has fewer configuration options than this library, and does not allow `NaN` or `Infinity`.
|
||||
|
||||
See also [decimal.js](https://github.com/MikeMcl/decimal.js/), which among other things adds support for non-integer powers, and performs all operations to a specified number of significant digits.
|
||||
|
||||

|
||||
import BigNumber from "bignumber.js";
|
||||
```
|
||||
|
||||
### [Deno](https://deno.land/)
|
||||
|
||||
```javascript
|
||||
// @deno-types="https://raw.githubusercontent.com/mikemcl/bignumber.js/v9.3.1/bignumber.d.mts"
|
||||
import BigNumber from 'https://raw.githubusercontent.com/mikemcl/bignumber.js/v9.3.1/bignumber.mjs';
|
||||
|
||||
// @deno-types="https://unpkg.com/bignumber.js@latest/bignumber.d.mts"
|
||||
import { BigNumber } from 'https://unpkg.com/bignumber.js@latest/bignumber.mjs';
|
||||
```
|
||||
|
||||
## Use
|
||||
|
||||
The library exports a single constructor function, [`BigNumber`](http://mikemcl.github.io/bignumber.js/#bignumber), which accepts a value of type Number, String or BigNumber,
|
||||
|
||||
```javascript
|
||||
let x = new BigNumber(123.4567);
|
||||
let y = BigNumber('123456.7e-3');
|
||||
let z = new BigNumber(x);
|
||||
x.isEqualTo(y) && y.isEqualTo(z) && x.isEqualTo(z); // true
|
||||
```
|
||||
|
||||
To get the string value of a BigNumber use [`toString()`](http://mikemcl.github.io/bignumber.js/#toS) or [`toFixed()`](http://mikemcl.github.io/bignumber.js/#toFix). Using `toFixed()` prevents exponential notation being returned, no matter how large or small the value.
|
||||
|
||||
```javascript
|
||||
let x = new BigNumber('1111222233334444555566');
|
||||
x.toString(); // "1.111222233334444555566e+21"
|
||||
x.toFixed(); // "1111222233334444555566"
|
||||
```
|
||||
|
||||
If the limited precision of Number values is not well understood, it is recommended to create BigNumbers from String values rather than Number values to avoid a potential loss of precision.
|
||||
|
||||
*In all further examples below, `let`, semicolons and `toString` calls are not shown. If a commented-out value is in quotes it means `toString` has been called on the preceding expression.*
|
||||
|
||||
```javascript
|
||||
// Precision loss from using numeric literals with more than 15 significant digits.
|
||||
new BigNumber(1.0000000000000001) // '1'
|
||||
new BigNumber(88259496234518.57) // '88259496234518.56'
|
||||
new BigNumber(99999999999999999999) // '100000000000000000000'
|
||||
|
||||
// Precision loss from using numeric literals outside the range of Number values.
|
||||
new BigNumber(2e+308) // 'Infinity'
|
||||
new BigNumber(1e-324) // '0'
|
||||
|
||||
// Precision loss from the unexpected result of arithmetic with Number values.
|
||||
new BigNumber(0.7 + 0.1) // '0.7999999999999999'
|
||||
```
|
||||
|
||||
When creating a BigNumber from a Number, note that a BigNumber is created from a Number's decimal `toString()` value not from its underlying binary value. If the latter is required, then pass the Number's `toString(2)` value and specify base 2.
|
||||
|
||||
```javascript
|
||||
new BigNumber(Number.MAX_VALUE.toString(2), 2)
|
||||
```
|
||||
|
||||
BigNumbers can be created from values in bases from 2 to 36. See [`ALPHABET`](http://mikemcl.github.io/bignumber.js/#alphabet) to extend this range.
|
||||
|
||||
```javascript
|
||||
a = new BigNumber(1011, 2) // "11"
|
||||
b = new BigNumber('zz.9', 36) // "1295.25"
|
||||
c = a.plus(b) // "1306.25"
|
||||
```
|
||||
|
||||
*Performance is better if base 10 is NOT specified for decimal values. Only specify base 10 when you want to limit the number of decimal places of the input value to the current [`DECIMAL_PLACES`](http://mikemcl.github.io/bignumber.js/#decimal-places) setting.*
|
||||
|
||||
A BigNumber is immutable in the sense that it is not changed by its methods.
|
||||
|
||||
```javascript
|
||||
0.3 - 0.1 // 0.19999999999999998
|
||||
x = new BigNumber(0.3)
|
||||
x.minus(0.1) // "0.2"
|
||||
x // "0.3"
|
||||
```
|
||||
|
||||
The methods that return a BigNumber can be chained.
|
||||
|
||||
```javascript
|
||||
x.dividedBy(y).plus(z).times(9)
|
||||
x.times('1.23456780123456789e+9').plus(9876.5432321).dividedBy('4444562598.111772').integerValue()
|
||||
```
|
||||
|
||||
Some of the longer method names have a shorter alias.
|
||||
|
||||
```javascript
|
||||
x.squareRoot().dividedBy(y).exponentiatedBy(3).isEqualTo(x.sqrt().div(y).pow(3)) // true
|
||||
x.modulo(y).multipliedBy(z).eq(x.mod(y).times(z)) // true
|
||||
```
|
||||
|
||||
As with JavaScript's Number type, there are [`toExponential`](http://mikemcl.github.io/bignumber.js/#toE), [`toFixed`](http://mikemcl.github.io/bignumber.js/#toFix) and [`toPrecision`](http://mikemcl.github.io/bignumber.js/#toP) methods.
|
||||
|
||||
```javascript
|
||||
x = new BigNumber(255.5)
|
||||
x.toExponential(5) // "2.55500e+2"
|
||||
x.toFixed(5) // "255.50000"
|
||||
x.toPrecision(5) // "255.50"
|
||||
x.toNumber() // 255.5
|
||||
```
|
||||
|
||||
A base can be specified for [`toString`](http://mikemcl.github.io/bignumber.js/#toS).
|
||||
|
||||
*Performance is better if base 10 is NOT specified, i.e. use `toString()` not `toString(10)`. Only specify base 10 when you want to limit the number of decimal places of the string to the current [`DECIMAL_PLACES`](http://mikemcl.github.io/bignumber.js/#decimal-places) setting.*
|
||||
|
||||
```javascript
|
||||
x.toString(16) // "ff.8"
|
||||
```
|
||||
|
||||
There is a [`toFormat`](http://mikemcl.github.io/bignumber.js/#toFor) method which may be useful for internationalisation.
|
||||
|
||||
```javascript
|
||||
y = new BigNumber('1234567.898765')
|
||||
y.toFormat(2) // "1,234,567.90"
|
||||
```
|
||||
|
||||
The maximum number of decimal places of the result of an operation involving division (i.e. a division, square root, base conversion or negative power operation) is set using the `set` or `config` method of the `BigNumber` constructor.
|
||||
|
||||
The other arithmetic operations always give the exact result.
|
||||
|
||||
```javascript
|
||||
BigNumber.set({ DECIMAL_PLACES: 10, ROUNDING_MODE: 4 })
|
||||
|
||||
x = new BigNumber(2)
|
||||
y = new BigNumber(3)
|
||||
z = x.dividedBy(y) // "0.6666666667"
|
||||
z.squareRoot() // "0.8164965809"
|
||||
z.exponentiatedBy(-3) // "3.3749999995"
|
||||
z.toString(2) // "0.1010101011"
|
||||
z.multipliedBy(z) // "0.44444444448888888889"
|
||||
z.multipliedBy(z).decimalPlaces(10) // "0.4444444445"
|
||||
```
|
||||
|
||||
There is a [`toFraction`](http://mikemcl.github.io/bignumber.js/#toFr) method with an optional *maximum denominator* argument
|
||||
|
||||
```javascript
|
||||
y = new BigNumber(355)
|
||||
pi = y.dividedBy(113) // "3.1415929204"
|
||||
pi.toFraction() // [ "7853982301", "2500000000" ]
|
||||
pi.toFraction(1000) // [ "355", "113" ]
|
||||
```
|
||||
|
||||
and [`isNaN`](http://mikemcl.github.io/bignumber.js/#isNaN) and [`isFinite`](http://mikemcl.github.io/bignumber.js/#isF) methods, as `NaN` and `Infinity` are valid `BigNumber` values.
|
||||
|
||||
```javascript
|
||||
x = new BigNumber(NaN) // "NaN"
|
||||
y = new BigNumber(Infinity) // "Infinity"
|
||||
x.isNaN() && !y.isNaN() && !x.isFinite() && !y.isFinite() // true
|
||||
```
|
||||
|
||||
The value of a BigNumber is stored in a decimal floating point format in terms of a coefficient, exponent and sign.
|
||||
|
||||
```javascript
|
||||
x = new BigNumber(-123.456);
|
||||
x.c // [ 123, 45600000000000 ] coefficient (i.e. significand)
|
||||
x.e // 2 exponent
|
||||
x.s // -1 sign
|
||||
```
|
||||
|
||||
For advanced usage, multiple BigNumber constructors can be created, each with its own independent configuration.
|
||||
|
||||
```javascript
|
||||
// Set DECIMAL_PLACES for the original BigNumber constructor
|
||||
BigNumber.set({ DECIMAL_PLACES: 10 })
|
||||
|
||||
// Create another BigNumber constructor, optionally passing in a configuration object
|
||||
BN = BigNumber.clone({ DECIMAL_PLACES: 5 })
|
||||
|
||||
x = new BigNumber(1)
|
||||
y = new BN(1)
|
||||
|
||||
x.div(3) // '0.3333333333'
|
||||
y.div(3) // '0.33333'
|
||||
```
|
||||
|
||||
To avoid having to call `toString` or `valueOf` on a BigNumber to get its value in the Node.js REPL or when using `console.log` use
|
||||
|
||||
```javascript
|
||||
BigNumber.prototype[require('util').inspect.custom] = BigNumber.prototype.valueOf;
|
||||
```
|
||||
|
||||
For further information see the [API](http://mikemcl.github.io/bignumber.js/) reference in the *doc* directory.
|
||||
|
||||
## Test
|
||||
|
||||
The *test/modules* directory contains the test scripts for each method.
|
||||
|
||||
The tests can be run with Node.js or a browser. For Node.js use
|
||||
|
||||
```bash
|
||||
npm test
|
||||
```
|
||||
|
||||
or
|
||||
|
||||
```bash
|
||||
node test/test
|
||||
```
|
||||
|
||||
To test a single method, use, for example
|
||||
|
||||
```bash
|
||||
node test/methods/toFraction
|
||||
```
|
||||
|
||||
For the browser, open *test/test.html*.
|
||||
|
||||
## Minify
|
||||
|
||||
To minify using, for example, [terser](https://github.com/terser/terser)
|
||||
|
||||
```bash
|
||||
npm install -g terser
|
||||
```
|
||||
|
||||
```bash
|
||||
terser big.js -c -m -o big.min.js
|
||||
```

Node.js body parsing middleware.
|
||||
|
||||
Parse incoming request bodies in a middleware before your handlers, available
|
||||
under the `req.body` property.
|
||||
|
||||
**Note** As `req.body`'s shape is based on user-controlled input, all
|
||||
properties and values in this object are untrusted and should be validated
|
||||
before trusting. For example, `req.body.foo.toString()` may fail in multiple
|
||||
ways, for example the `foo` property may not be there or may not be a string,
|
||||
and `toString` may not be a function and instead a string or other user input.

|
||||
|
||||
_This does not handle multipart bodies_, due to their complex and typically
|
||||
large nature. For multipart bodies, you may be interested in the following
|
||||
modules:
|
||||
|
||||
* [busboy](https://www.npmjs.com/package/busboy#readme) and
|
||||
[connect-busboy](https://www.npmjs.com/package/connect-busboy#readme)
|
||||
* [multiparty](https://www.npmjs.com/package/multiparty#readme) and
|
||||
[connect-multiparty](https://www.npmjs.com/package/connect-multiparty#readme)
|
||||
* [formidable](https://www.npmjs.com/package/formidable#readme)
|
||||
* [multer](https://www.npmjs.com/package/multer#readme)
|
||||
|
||||
This module provides the following parsers:
|
||||
|
||||
* [JSON body parser](#bodyparserjsonoptions)
|
||||
* [Raw body parser](#bodyparserrawoptions)
|
||||
* [Text body parser](#bodyparsertextoptions)
|
||||
* [URL-encoded form body parser](#bodyparserurlencodedoptions)
|
||||
|
||||
Other body parsers you might be interested in:
|
||||
|
||||
- [body](https://www.npmjs.com/package/body#readme)
|
||||
- [co-body](https://www.npmjs.com/package/co-body#readme)
|
||||
|
||||
## Installation
|
||||
|
||||
```sh
|
||||
$ npm install body-parser
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
```js
|
||||
// Import all parsers
|
||||
const bodyParser = require('body-parser')
|
||||
|
||||
// Or import individual parsers directly
|
||||
const json = require('body-parser/json')
|
||||
const urlencoded = require('body-parser/urlencoded')
|
||||
const raw = require('body-parser/raw')
|
||||
const text = require('body-parser/text')
|
||||
```
|
||||
|
||||
The `bodyParser` object exposes various factories to create middlewares. All
|
||||
middlewares will populate the `req.body` property with the parsed body when
|
||||
the `Content-Type` request header matches the `type` option.
|
||||
|
||||
The various errors returned by this module are described in the
|
||||
[errors section](#errors).
|
||||
|
||||
### bodyParser.json([options])
|
||||
|
||||
Returns middleware that only parses `json` and only looks at requests where
|
||||
the `Content-Type` header matches the `type` option. This parser accepts any
|
||||
Unicode encoding of the body and supports automatic inflation of `gzip`,
|
||||
`br` (brotli) and `deflate` encodings.
|
||||
|
||||
A new `body` object containing the parsed data is populated on the `request`
|
||||
object after the middleware (i.e. `req.body`).
|
||||
|
||||
#### Options
|
||||
|
||||
The `json` function takes an optional `options` object that may contain any of
|
||||
the following keys:
|
||||
|
||||
##### defaultCharset
|
||||
|
||||
Specify the default character set for the json content if the charset is not
|
||||
specified in the `Content-Type` header of the request. Defaults to `utf-8`.
|
||||
|
||||
##### inflate
|
||||
|
||||
When set to `true`, then deflated (compressed) bodies will be inflated; when
|
||||
`false`, deflated bodies are rejected. Defaults to `true`.
|
||||
|
||||
##### limit
|
||||
|
||||
Controls the maximum request body size. If this is a number, then the value
|
||||
specifies the number of bytes; if it is a string, the value is passed to the
|
||||
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
|
||||
to `'100kb'`.
|
||||
|
||||
> It’s recommended not to configure a very high limit and to use the default value whenever possible. Allowing larger payloads increases memory usage because of the resources required for decoding and transformations, and it can also lead to longer response times as more data is processed. By ‘very high’, we mean values above the default, for example payloads of 5 MB or more can already start to introduce these risks. With the default limits, these issues do not occur.
|
||||
|
||||
##### reviver
|
||||
|
||||
The `reviver` option is passed directly to `JSON.parse` as the second
|
||||
argument. You can find more information on this argument
|
||||
[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#the_reviver_parameter).
|
||||
|
||||
##### strict
|
||||
|
||||
When set to `true`, will only accept arrays and objects; when `false` will
|
||||
accept anything `JSON.parse` accepts. Defaults to `true`.
|
||||
|
||||
##### type
|
||||
|
||||
The `type` option is used to determine what media type the middleware will
|
||||
parse. This option can be a string, array of strings, or a function. If not a
|
||||
function, `type` option is passed directly to the
|
||||
[type-is](https://www.npmjs.com/package/type-is#readme) library and this can
|
||||
be an extension name (like `json`), a mime type (like `application/json`), or
|
||||
a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type`
|
||||
option is called as `fn(req)` and the request is parsed if it returns a truthy
|
||||
value. Defaults to `application/json`.
|
||||
|
||||
##### verify
|
||||
|
||||
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
|
||||
where `buf` is a `Buffer` of the raw request body and `encoding` is the
|
||||
encoding of the request. The parsing can be aborted by throwing an error.
|
||||
|
||||
### bodyParser.raw([options])
|
||||
|
||||
Returns middleware that parses all bodies as a `Buffer` and only looks at
|
||||
requests where the `Content-Type` header matches the `type` option. This
|
||||
parser supports automatic inflation of `gzip`, `br` (brotli) and `deflate`
|
||||
encodings.
|
||||
|
||||
A new `body` object containing the parsed data is populated on the `request`
|
||||
object after the middleware (i.e. `req.body`). This will be a `Buffer` object
|
||||
of the body.
|
||||
|
||||
#### Options
|
||||
|
||||
The `raw` function takes an optional `options` object that may contain any of
|
||||
the following keys:
|
||||
|
||||
##### inflate
|
||||
|
||||
When set to `true`, then deflated (compressed) bodies will be inflated; when
|
||||
`false`, deflated bodies are rejected. Defaults to `true`.
|
||||
|
||||
##### limit
|
||||
|
||||
Controls the maximum request body size. If this is a number, then the value
|
||||
specifies the number of bytes; if it is a string, the value is passed to the
|
||||
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
|
||||
to `'100kb'`.
|
||||
|
||||
> It’s recommended not to configure a very high limit and to use the default value whenever possible. Allowing larger payloads increases memory usage because of the resources required for decoding and transformations, and it can also lead to longer response times as more data is processed. By ‘very high’, we mean values above the default, for example payloads of 5 MB or more can already start to introduce these risks. With the default limits, these issues do not occur.
|
||||
|
||||
##### type
|
||||
|
||||
The `type` option is used to determine what media type the middleware will
|
||||
parse. This option can be a string, array of strings, or a function.
|
||||
If not a function, `type` option is passed directly to the
|
||||
[type-is](https://www.npmjs.com/package/type-is#readme) library and this
|
||||
can be an extension name (like `bin`), a mime type (like
|
||||
`application/octet-stream`), or a mime type with a wildcard (like `*/*` or
|
||||
`application/*`). If a function, the `type` option is called as `fn(req)`
|
||||
and the request is parsed if it returns a truthy value. Defaults to
|
||||
`application/octet-stream`.
|
||||
|
||||
##### verify
|
||||
|
||||
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
|
||||
where `buf` is a `Buffer` of the raw request body and `encoding` is the
|
||||
encoding of the request. The parsing can be aborted by throwing an error.
|
||||
|
||||
### bodyParser.text([options])
|
||||
|
||||
Returns middleware that parses all bodies as a string and only looks at
|
||||
requests where the `Content-Type` header matches the `type` option. This
|
||||
parser supports automatic inflation of `gzip`, `br` (brotli) and `deflate`
|
||||
encodings.
|
||||
|
||||
A new `body` string containing the parsed data is populated on the `request`
|
||||
object after the middleware (i.e. `req.body`). This will be a string of the
|
||||
body.
|
||||
|
||||
#### Options
|
||||
|
||||
The `text` function takes an optional `options` object that may contain any of
|
||||
the following keys:
|
||||
|
||||
##### defaultCharset
|
||||
|
||||
Specify the default character set for the text content if the charset is not
|
||||
specified in the `Content-Type` header of the request. Defaults to `utf-8`.
|
||||
|
||||
##### inflate
|
||||
|
||||
When set to `true`, then deflated (compressed) bodies will be inflated; when
|
||||
`false`, deflated bodies are rejected. Defaults to `true`.
|
||||
|
||||
##### limit
|
||||
|
||||
Controls the maximum request body size. If this is a number, then the value
|
||||
specifies the number of bytes; if it is a string, the value is passed to the
|
||||
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
|
||||
to `'100kb'`.
|
||||
|
||||
> It’s recommended not to configure a very high limit and to use the default value whenever possible.

|
||||
|
||||
##### type
|
||||
|
||||
The `type` option is used to determine what media type the middleware will
|
||||
parse. This option can be a string, array of strings, or a function. If not
|
||||
a function, `type` option is passed directly to the
|
||||
[type-is](https://www.npmjs.com/package/type-is#readme) library and this can
|
||||
be an extension name (like `txt`), a mime type (like `text/plain`), or a mime
|
||||
type with a wildcard (like `*/*` or `text/*`). If a function, the `type`
|
||||
option is called as `fn(req)` and the request is parsed if it returns a
|
||||
truthy value. Defaults to `text/plain`.
|
||||
|
||||
##### verify
|
||||
|
||||
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
|
||||
where `buf` is a `Buffer` of the raw request body and `encoding` is the
|
||||
encoding of the request. The parsing can be aborted by throwing an error.
|
||||
|
||||
### bodyParser.urlencoded([options])
|
||||
|
||||
Returns middleware that only parses `urlencoded` bodies and only looks at
|
||||
requests where the `Content-Type` header matches the `type` option. This
|
||||
parser accepts only UTF-8 and ISO-8859-1 encodings of the body and supports
|
||||
automatic inflation of `gzip`, `br` (brotli) and `deflate` encodings.
|
||||
|
||||
A new `body` object containing the parsed data is populated on the `request`
|
||||
object after the middleware (i.e. `req.body`). This object will contain
|
||||
key-value pairs, where the value can be a string or array (when `extended` is
|
||||
`false`), or any type (when `extended` is `true`).
|
||||
|
||||
#### Options
|
||||
|
||||
The `urlencoded` function takes an optional `options` object that may contain
|
||||
any of the following keys:
|
||||
|
||||
##### extended
|
||||
|
||||
The "extended" syntax allows for rich objects and arrays to be encoded into the
|
||||
URL-encoded format, allowing for a JSON-like experience with URL-encoded. For
|
||||
more information, please [see the qs
|
||||
library](https://www.npmjs.com/package/qs#readme).
|
||||
|
||||
Defaults to `false`.
|
||||
|
||||
##### inflate
|
||||
|
||||
When set to `true`, then deflated (compressed) bodies will be inflated; when
|
||||
`false`, deflated bodies are rejected. Defaults to `true`.
|
||||
|
||||
##### limit
|
||||
|
||||
Controls the maximum request body size. If this is a number, then the value
|
||||
specifies the number of bytes; if it is a string, the value is passed to the
|
||||
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
|
||||
to `'100kb'`.
|
||||
|
||||
> It’s recommended not to configure a very high limit and to use the default value whenever possible. Allowing larger payloads increases memory usage because of the resources required for decoding and transformations, and it can also lead to longer response times as more data is processed. By ‘very high’, we mean values above the default, for example payloads of 5 MB or more can already start to introduce these risks. With the default limits, these issues do not occur.
|
||||
|
||||
##### parameterLimit
|
||||
|
||||
The `parameterLimit` option controls the maximum number of parameters that
|
||||
are allowed in the URL-encoded data. If a request contains more parameters
|
||||
than this value, a 413 will be returned to the client. Defaults to `1000`.
|
||||
|
||||
##### type
|
||||
|
||||
The `type` option is used to determine what media type the middleware will
|
||||
parse. This option can be a string, array of strings, or a function. If not
|
||||
a function, `type` option is passed directly to the
|
||||
[type-is](https://www.npmjs.com/package/type-is#readme) library and this can
|
||||
be an extension name (like `urlencoded`), a mime type (like
|
||||
`application/x-www-form-urlencoded`), or a mime type with a wildcard (like
|
||||
`*/x-www-form-urlencoded`). If a function, the `type` option is called as
|
||||
`fn(req)` and the request is parsed if it returns a truthy value. Defaults
|
||||
to `application/x-www-form-urlencoded`.
|
||||
|
||||
##### verify
|
||||
|
||||
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
|
||||
where `buf` is a `Buffer` of the raw request body and `encoding` is the
|
||||
encoding of the request. The parsing can be aborted by throwing an error.
|
||||
|
||||
##### defaultCharset
|
||||
|
||||
The default charset to parse as, if not specified in content-type. Must be
|
||||
either `utf-8` or `iso-8859-1`. Defaults to `utf-8`.
|
||||
|
||||
##### charsetSentinel
|
||||
|
||||
Whether to let the value of the `utf8` parameter take precedence as the charset
|
||||
selector. It requires the form to contain a parameter named `utf8` with a value
|
||||
of `✓`. Defaults to `false`.
|
||||
|
||||
##### interpretNumericEntities
|
||||
|
||||
Whether to decode numeric entities such as `☺` when parsing an iso-8859-1
|
||||
form. Defaults to `false`.
|
||||
|
||||
|
||||
##### depth
|
||||
|
||||
The `depth` option is used to configure the maximum depth of the `qs` library when `extended` is `true`. This allows you to limit the amount of keys that are parsed and can be useful to prevent certain types of abuse. Defaults to `32`. It is recommended to keep this value as low as possible.
|
||||
|
||||
## Errors
|
||||
|
||||
The middlewares provided by this module create errors using the
|
||||
[`http-errors` module](https://www.npmjs.com/package/http-errors). The errors
|
||||
will typically have a `status`/`statusCode` property that contains the suggested
|
||||
HTTP response code, an `expose` property to determine if the `message` property
|
||||
should be displayed to the client, a `type` property to determine the type of
|
||||
error without matching against the `message`, and a `body` property containing
|
||||
the read body, if available.
|
||||
|
||||
The following are the common errors created, though any error can come through
|
||||
for various reasons.
|
||||
|
||||
### content encoding unsupported
|
||||
|
||||
This error will occur when the request had a `Content-Encoding` header that
|
||||
contained an encoding but the "inflation" option was set to `false`. The
|
||||
`status` property is set to `415`, the `type` property is set to
|
||||
`'encoding.unsupported'`, and the `charset` property will be set to the
|
||||
encoding that is unsupported.
|
||||
|
||||
### entity parse failed
|
||||
|
||||
This error will occur when the request contained an entity that could not be
|
||||
parsed by the middleware. The `status` property is set to `400`, the `type`
|
||||
property is set to `'entity.parse.failed'`, and the `body` property is set to
|
||||
the entity value that failed parsing.
|
||||
|
||||
### entity verify failed
|
||||
|
||||
This error will occur when the request contained an entity that could not be
|
||||
failed verification by the defined `verify` option. The `status` property is
|
||||
set to `403`, the `type` property is set to `'entity.verify.failed'`, and the
|
||||
`body` property is set to the entity value that failed verification.
|
||||
|
||||
### request aborted
|
||||
|
||||
This error will occur when the request is aborted by the client before reading
|
||||
the body has finished. The `received` property will be set to the number of
|
||||
bytes received before the request was aborted and the `expected` property is
|
||||
set to the number of expected bytes. The `status` property is set to `400`
|
||||
and `type` property is set to `'request.aborted'`.
|
||||
|
||||
### request entity too large
|
||||
|
||||
This error will occur when the request body's size is larger than the "limit"
|
||||
option. The `limit` property will be set to the byte limit and the `length`
|
||||
property will be set to the request body's length. The `status` property is
|
||||
set to `413` and the `type` property is set to `'entity.too.large'`.
|
||||
|
||||
### request size did not match content length
|
||||
|
||||
This error will occur when the request's length did not match the length from
|
||||
the `Content-Length` header. This typically occurs when the request is malformed,
|
||||
typically when the `Content-Length` header was calculated based on characters
|
||||
instead of bytes. The `status` property is set to `400` and the `type` property
|
||||
is set to `'request.size.invalid'`.
|
||||
|
||||
### stream encoding should not be set
|
||||
|
||||
This error will occur when something called the `req.setEncoding` method prior
|
||||
to this middleware. This module operates directly on bytes only and you cannot
|
||||
call `req.setEncoding` when using this module. The `status` property is set to
|
||||
`500` and the `type` property is set to `'stream.encoding.set'`.
|
||||
|
||||
### stream is not readable
|
||||
|
||||
This error will occur when the request is no longer readable when this middleware
|
||||
attempts to read it. This typically means something other than a middleware from
|
||||
this module read the request body already and the middleware was also configured to
|
||||
read the same request. The `status` property is set to `500` and the `type`
|
||||
property is set to `'stream.not.readable'`.
|
||||
|
||||
### too many parameters
|
||||
|
||||
This error will occur when the content of the request exceeds the configured
|
||||
`parameterLimit` for the `urlencoded` parser. The `status` property is set to
|
||||
`413` and the `type` property is set to `'parameters.too.many'`.
|
||||
|
||||
### unsupported charset "BOGUS"
|
||||
|
||||
This error will occur when the request had a charset parameter in the
|
||||
`Content-Type` header, but the `iconv-lite` module does not support it OR the
|
||||
parser does not support it. The charset is contained in the message as well
|
||||
as in the `charset` property. The `status` property is set to `415`, the
|
||||
`type` property is set to `'charset.unsupported'`, and the `charset` property
|
||||
is set to the charset that is unsupported.
|
||||
|
||||
### unsupported content encoding "bogus"
|
||||
|
||||
This error will occur when the request had a `Content-Encoding` header that
|
||||
contained an unsupported encoding. The encoding is contained in the message
|
||||
as well as in the `encoding` property. The `status` property is set to `415`,
|
||||
the `type` property is set to `'encoding.unsupported'`, and the `encoding`
|
||||
property is set to the encoding that is unsupported.
|
||||
|
||||
### The input exceeded the depth
|
||||
|
||||
This error occurs when using `bodyParser.urlencoded` with the `extended` property set to `true` and the input exceeds the configured `depth` option. The `status` property is set to `400`. It is recommended to review the `depth` option and evaluate if it requires a higher value. When the `depth` option is set to `32` (default value), the error will not be thrown.
|
||||
|
||||
## Examples
|
||||
|
||||
### Express/Connect top-level generic
|
||||
|
||||
This example demonstrates adding a generic JSON and URL-encoded parser as a
|
||||
top-level middleware, which will parse the bodies of all incoming requests.
|
||||
This is the simplest setup.
|
||||
|
||||
```js
|
||||
const express = require('express')
|
||||
const bodyParser = require('body-parser')
|
||||
|
||||
const app = express()
|
||||
|
||||
// parse application/x-www-form-urlencoded
|
||||
app.use(bodyParser.urlencoded())
|
||||
|
||||
// parse application/json
|
||||
app.use(bodyParser.json())
|
||||
|
||||
app.use(function (req, res) {
|
||||
res.setHeader('Content-Type', 'text/plain')
|
||||
res.write('you posted:\n')
|
||||
res.end(String(JSON.stringify(req.body, null, 2)))
|
||||
})
|
||||
```
|
||||
|
||||
### Express route-specific
|
||||
|
||||
This example demonstrates adding body parsers specifically to the routes that
|
||||
need them. In general, this is the most recommended way to use body-parser with
|
||||
Express.
|
||||
|
||||
```js
|
||||
const express = require('express')
|
||||
const bodyParser = require('body-parser')
|
||||
|
||||
const app = express()
|
||||
|
||||
// create application/json parser
|
||||
const jsonParser = bodyParser.json()
|
||||
|
||||
// create application/x-www-form-urlencoded parser
|
||||
const urlencodedParser = bodyParser.urlencoded()
|
||||
|
||||
// POST /login gets urlencoded bodies
|
||||
app.post('/login', urlencodedParser, function (req, res) {
|
||||
if (!req.body || !req.body.username) res.sendStatus(400)
|
||||
res.send('welcome, ' + req.body.username)
|
||||
})
|
||||
|
||||
// POST /api/users gets JSON bodies
|
||||
app.post('/api/users', jsonParser, function (req, res) {
|
||||
if (!req.body) res.sendStatus(400)
|
||||
// create user in req.body
|
||||
})
|
||||
```
|
||||
|
||||
### Change accepted type for parsers
|
||||
|
||||
All the parsers accept a `type` option which allows you to change the
|
||||
`Content-Type` that the middleware will parse.
|
||||
|
||||
```js
|
||||
const express = require('express')
|
||||
const bodyParser = require('body-parser')
|
||||
|
||||
const app = express()
|
||||
|
||||
// parse various different custom JSON types as JSON
|
||||
app.use(bodyParser.json({ type: 'application/*+json' }))
|
||||
|
||||
// parse some custom thing into a Buffer
|
||||
app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }))
|
||||
|
||||
// parse an HTML body into a string
|
||||
app.use(bodyParser.text({ type: 'text/html' }))
|
||||
```

|
||||
|
||||
Create and parse HTTP `Content-Type` header.
|
||||
|
||||
## Installation
|
||||
|
||||
```sh
|
||||
npm install content-type
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
```js
|
||||
const contentType = require("content-type");
|
||||
```
|
||||
|
||||
### contentType.parse(string, options?)
|
||||
|
||||
```js
|
||||
const obj = contentType.parse("image/svg+xml; charset=utf-8");
|
||||
```
|
||||
|
||||
Parse a `Content-Type` header. This will return an object with the following properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`):
|
||||
|
||||
- `type`: The media type. Example: `'image/svg+xml'`.
|
||||
- `parameters`: An object of the parameters in the media type (parameter name is always lower case). Example: `{charset: 'utf-8'}`.
|
||||
|
||||
The parser is lenient and does not error. You should validate `type` and `parameters` before trusting them.
|
||||
|
||||
#### Options
|
||||
|
||||
- `parameters` (default: `true`): Set to `false` to skip parameters.
|
||||
|
||||
### contentType.format(obj)
|
||||
|
||||
```js
|
||||
const str = contentType.format({
|
||||
type: "image/svg+xml",
|
||||
parameters: { charset: "utf-8" },
|
||||
});
|
||||
```
|
||||
|
||||
Format an object into a `Content-Type` header. This will return a string of the content type for the given object with the following properties (examples are shown that produce the string `'image/svg+xml; charset=utf-8'`):
|
||||
|
||||
- `type`: The media type. Example: `'image/svg+xml'`.
|
||||
- `parameters`: An optional object of the parameters in the media type. Example: `{charset: 'utf-8'}`.
|
||||
|
||||
Throws a `TypeError` if the object contains an invalid type or parameter names.

|
||||
|
||||
Utility to parse a string bytes (ex: `1TB`) to bytes (`1099511627776`) and vice-versa.
|
||||
|
||||
## Installation
|
||||
|
||||
This is a [Node.js](https://nodejs.org/en/) module available through the
|
||||
[npm registry](https://www.npmjs.com/). Installation is done using the
|
||||
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
|
||||
|
||||
```bash
|
||||
$ npm install bytes
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```js
|
||||
var bytes = require('bytes');
|
||||
```
|
||||
|
||||
#### bytes(number｜string value, [options]): number｜string｜null
|
||||
|
||||
Default export function. Delegates to either `bytes.format` or `bytes.parse` based on the type of `value`.
|
||||
|
||||
**Arguments**
|
||||
|
||||
| Name | Type | Description |
|
||||
|---------|----------|--------------------|
|
||||
| value | `number`｜`string` | Number value to format or string value to parse |
|
||||
| options | `Object` | Conversion options for `format` |
|
||||
|
||||
**Returns**
|
||||
|
||||
| Name | Type | Description |
|
||||
|---------|------------------|-------------------------------------------------|
|
||||
| results | `string`｜`number`｜`null` | Return null upon error. Numeric value in bytes, or string value otherwise. |
|
||||
|
||||
**Example**
|
||||
|
||||
```js
|
||||
bytes(1024);
|
||||
// output: '1KB'
|
||||
|
||||
bytes('1KB');
|
||||
// output: 1024
|
||||
```
|
||||
|
||||
#### bytes.format(number value, [options]): string｜null
|
||||
|
||||
Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is
|
||||
rounded.
|
||||
|
||||
**Arguments**
|
||||
|
||||
| Name | Type | Description |
|
||||
|---------|----------|--------------------|
|
||||
| value | `number` | Value in bytes |
|
||||
| options | `Object` | Conversion options |
|
||||
|
||||
**Options**
|
||||
|
||||
| Property | Type | Description |
|
||||
|-------------------|--------|-----------------------------------------------------------------------------------------|
|
||||
| decimalPlaces | `number`｜`null` | Maximum number of decimal places to include in output. Default value to `2`. |
|
||||
| fixedDecimals | `boolean`｜`null` | Whether to always display the maximum number of decimal places. Default value to `false` |
|
||||
| thousandsSeparator | `string`｜`null` | Example of values: `' '`, `','` and `'.'`... Default value to `''`. |
|
||||
| unit | `string`｜`null` | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to `''` (which means auto detect). |
|
||||
| unitSeparator | `string`｜`null` | Separator to use between number and unit. Default value to `''`. |
|
||||
|
||||
**Returns**
|
||||
|
||||
| Name | Type | Description |
|
||||
|---------|------------------|-------------------------------------------------|
|
||||
| results | `string`｜`null` | Return null upon error. String value otherwise. |
|
||||
|
||||
**Example**
|
||||
|
||||
```js
|
||||
bytes.format(1024);
|
||||
// output: '1KB'
|
||||
|
||||
bytes.format(1000);
|
||||
// output: '1000B'
|
||||
|
||||
bytes.format(1000, {thousandsSeparator: ' '});
|
||||
// output: '1 000B'
|
||||
|
||||
bytes.format(1024 * 1.7, {decimalPlaces: 0});
|
||||
// output: '2KB'
|
||||
|
||||
bytes.format(1024, {unitSeparator: ' '});
|
||||
// output: '1 KB'
|
||||
```
|
||||
|
||||
#### bytes.parse(string｜number value): number｜null
|
||||
|
||||
Parse the string value into an integer in bytes. If no unit is given, or `value`
|
||||
is a number, it is assumed the value is in bytes.
|
||||
|
||||
Supported units and abbreviations are as follows and are case-insensitive:
|
||||
|
||||
* `b` for bytes
|
||||
* `kb` for kilobytes
|
||||
* `mb` for megabytes
|
||||
* `gb` for gigabytes
|
||||
* `tb` for terabytes
|
||||
* `pb` for petabytes
|
||||
|
||||
The units are in powers of two, not ten. This means 1kb = 1024b according to this parser.
|
||||
|
||||
**Arguments**
|
||||
|
||||
| Name | Type | Description |
|
||||
|---------------|--------|--------------------|
|
||||
| value | `string`｜`number` | String to parse, or number in bytes. |
|
||||
|
||||
**Returns**
|
||||
|
||||
| Name | Type | Description |
|
||||
|---------|-------------|-------------------------|
|
||||
| results | `number`｜`null` | Return null upon error. Value in bytes otherwise. |
|
||||
|
||||
**Example**
|
||||
|
||||
```js
|
||||
bytes.parse('1KB');
|
||||
// output: 1024
|
||||
|
||||
bytes.parse('1024');
|
||||
// output: 1024
|
||||
|
||||
bytes.parse(1024);
|
||||
// output: 1024
|
||||

|
||||
|
||||
Helper functions around Function call/apply/bind, for use in `call-bind`.
|
||||
|
||||
The only packages that should likely ever use this package directly are `call-bind` and `get-intrinsic`.
|
||||
Please use `call-bind` unless you have a very good reason not to.
|
||||
|
||||
## Getting started
|
||||
|
||||
```sh
|
||||
npm install --save call-bind-apply-helpers
|
||||
```
|
||||
|
||||
## Usage/Examples
|
||||
|
||||
```js
|
||||
const assert = require('assert');
|
||||
const callBindBasic = require('call-bind-apply-helpers');
|
||||
|
||||
function f(a, b) {
|
||||
assert.equal(this, 1);
|
||||
assert.equal(a, 2);
|
||||
assert.equal(b, 3);
|
||||
assert.equal(arguments.length, 2);
|
||||
}
|
||||
|
||||
const fBound = callBindBasic([f, 1]);
|
||||
|
||||
delete Function.prototype.call;
|
||||
delete Function.prototype.bind;
|
||||
|
||||
fBound(2, 3);
|
||||
```
|
||||
|
||||
## Tests
|
||||
|
||||
Clone the repo, `npm install`, and run `npm test`

Robust call-bound JavaScript intrinsics, using `call-bind` and `get-intrinsic`.
|
||||
|
||||
## Getting started
|
||||
|
||||
```sh
|
||||
npm install --save call-bound
|
||||
```
|
||||
|
||||
## Usage/Examples
|
||||
|
||||
```js
|
||||
const assert = require('assert');
|
||||
const callBound = require('call-bound');
|
||||
|
||||
const slice = callBound('Array.prototype.slice');
|
||||
|
||||
delete Function.prototype.call;
|
||||
delete Function.prototype.bind;
|
||||
delete Array.prototype.slice;
|
||||
|
||||
assert.deepEqual(slice([1, 2, 3, 4], 1, -1), [2, 3]);
|
||||
```
|
||||
|
||||
## Tests
|
||||
|
||||
Clone the repo, `npm install`, and run `npm test`

# combined-stream
|
||||
|
||||
A stream that emits multiple other streams one after another.
|
||||
|
||||
**NB** Currently `combined-stream` works with streams version 1 only. There is ongoing effort to switch this library to streams version 2. Any help is welcome. :) Meanwhile you can explore other libraries that provide streams2 support with more or less compatibility with `combined-stream`.
|
||||
|
||||
- [combined-stream2](https://www.npmjs.com/package/combined-stream2): A drop-in streams2-compatible replacement for the combined-stream module.
|
||||
|
||||
- [multistream](https://www.npmjs.com/package/multistream): A stream that emits multiple other streams one after another.
|
||||
|
||||
## Installation
|
||||
|
||||
``` bash
|
||||
npm install combined-stream
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
Here is a simple example that shows how you can use combined-stream to combine
|
||||
two files into one:
|
||||
|
||||
``` javascript
|
||||
var CombinedStream = require('combined-stream');
|
||||
var fs = require('fs');
|
||||
|
||||
var combinedStream = CombinedStream.create();
|
||||
combinedStream.append(fs.createReadStream('file1.txt'));
|
||||
combinedStream.append(fs.createReadStream('file2.txt'));
|
||||
|
||||
combinedStream.pipe(fs.createWriteStream('combined.txt'));
|
||||
```
|
||||
|
||||
While the example above works great, it will pause all source streams until
|
||||
they are needed. If you don't want that to happen, you can set `pauseStreams`
|
||||
to `false`:
|
||||
|
||||
``` javascript
|
||||
var CombinedStream = require('combined-stream');
|
||||
var fs = require('fs');
|
||||
|
||||
var combinedStream = CombinedStream.create({pauseStreams: false});
|
||||
combinedStream.append(fs.createReadStream('file1.txt'));
|
||||
combinedStream.append(fs.createReadStream('file2.txt'));
|
||||
|
||||
combinedStream.pipe(fs.createWriteStream('combined.txt'));
|
||||
```
|
||||
|
||||
However, what if you don't have all the source streams yet, or you don't want
|
||||
to allocate the resources (file descriptors, memory, etc.) for them right away?
|
||||
Well, in that case you can simply provide a callback that supplies the stream
|
||||
by calling a `next()` function:
|
||||
|
||||
``` javascript
|
||||
var CombinedStream = require('combined-stream');
|
||||
var fs = require('fs');
|
||||
|
||||
var combinedStream = CombinedStream.create();
|
||||
combinedStream.append(function(next) {
|
||||
next(fs.createReadStream('file1.txt'));
|
||||
});
|
||||
combinedStream.append(function(next) {
|
||||
next(fs.createReadStream('file2.txt'));
|
||||
});
|
||||
|
||||
combinedStream.pipe(fs.createWriteStream('combined.txt'));
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
### CombinedStream.create([options])
|
||||
|
||||
Returns a new combined stream object. Available options are:
|
||||
|
||||
* `maxDataSize`
|
||||
* `pauseStreams`
|
||||
|
||||
The effect of those options is described below.
|
||||
|
||||
### combinedStream.pauseStreams = `true`
|
||||
|
||||
Whether to apply back pressure to the underlaying streams. If set to `false`,
|
||||
the underlaying streams will never be paused. If set to `true`, the
|
||||
underlaying streams will be paused right after being appended, as well as when
|
||||
`delayedStream.pipe()` wants to throttle.
|
||||
|
||||
### combinedStream.maxDataSize = `2 * 1024 * 1024`
|
||||
|
||||
The maximum amount of bytes (or characters) to buffer for all source streams.
|
||||
If this value is exceeded, `combinedStream` emits an `'error'` event.
|
||||
|
||||
### combinedStream.dataSize = `0`
|
||||
|
||||
The amount of bytes (or characters) currently buffered by `combinedStream`.
|
||||
|
||||
### combinedStream.append(stream)
|
||||
|
||||
Appends the given `stream` to the combinedStream object. If `pauseStreams` is
|
||||
set to `true, this stream will also be paused right away.
|
||||
|
||||
`streams` can also be a function that takes one parameter called `next`. `next`
|
||||
is a function that must be invoked in order to provide the `next` stream, see
|
||||
example above.
|
||||
|
||||
Regardless of how the `stream` is appended, combined-stream always attaches an
|
||||
`'error'` listener to it, so you don't have to do that manually.
|
||||
|
||||
Special case: `stream` can also be a String or Buffer.
|
||||
|
||||
### combinedStream.write(data)
|
||||
|
||||
You should not call this, `combinedStream` takes care of piping the appended
|
||||
streams into itself for you.
|
||||
|
||||
### combinedStream.resume()
|
||||
|
||||
Causes `combinedStream` to start drain the streams it manages. The function is
|
||||
idempotent, and also emits a `'resume'` event each time which usually goes to
|
||||
the stream that is currently being drained.
|
||||
|
||||
### combinedStream.pause();
|
||||
|
||||
If `combinedStream.pauseStreams` is set to `false`, this does nothing.
|
||||
Otherwise a `'pause'` event is emitted, this goes to the stream that is
|
||||
currently being drained, so you can use it to apply back pressure.
|
||||
|
||||
### combinedStream.end();
|
||||
|
||||
Sets `combinedStream.writable` to false, emits an `'end'` event, and removes
|
||||
all streams from the queue.
|
||||
|
||||
### combinedStream.destroy();
|
||||
|
||||
Same as `combinedStream.end()`, except it emits a `'close'` event instead of
|
||||
`'end'`.
