Configure your Node.js Applications
===================================
[![NPM](https://nodei.co/npm/config.svg?downloads=true&downloadRank=true)](https://nodei.co/npm/config/)  
[![Build Status](https://secure.travis-ci.org/node-config/node-config.svg?branch=master)](https://travis-ci.org/lorenwest/node-config)  
[release notes](https://github.com/node-config/node-config/blob/master/History.md)
Introduction
------------
Node-config organizes hierarchical configurations for your app deployments.
It lets you define a set of default parameters,
and extend them for different deployment environments (development, qa,
staging, production, etc.).
Configurations are stored in [configuration files](https://github.com/node-config/node-config/wiki/Configuration-Files) within your application, and can be overridden and extended by [environment variables](https://github.com/lorenwest/node-config/wiki/Environment-Variables),
[command line parameters](https://github.com/node-config/node-config/wiki/Command-Line-Overrides), or [external sources](https://github.com/lorenwest/node-config/wiki/Configuring-from-an-External-Source).
This gives your application a consistent configuration interface shared among a
[growing list of npm modules](https://www.npmjs.org/browse/depended/config) also using node-config.
Project Guidelines
------------------
* *Simple* - Get started fast
* *Powerful* - For multi-node enterprise deployment
* *Flexible* - Supporting multiple config file formats
* *Lightweight* - Small file and memory footprint
* *Predictable* - Well tested foundation for module and app developers
Quick Start
---------------
The following examples are in JSON format, but configurations can be in other [file formats](https://github.com/node-config/node-config/wiki/Configuration-Files#file-formats).
**Install in your app directory, and edit the default config file.**
```shell
$ npm install config
$ mkdir config
$ vi config/default.json
```
```js
{
// Customer module configs
"Customer": {
"dbConfig": {
"host": "localhost",
"port": 5984,
"dbName": "customers"
},
"credit": {
"initialLimit": 100,
// Set low for development
"initialDays": 1
}
}
}
```
**Edit config overrides for production deployment:**
```shell
$ vi config/production.json
```
```json
{
"Customer": {
"dbConfig": {
"host": "prod-db-server"
},
"credit": {
"initialDays": 30
}
}
}
```
**Use configs in your code:**
```js
const config = require('config');
//...
const dbConfig = config.get('Customer.dbConfig');
db.connect(dbConfig, ...);
if (config.has('optionalFeature.detail')) {
const detail = config.get('optionalFeature.detail');
//...
}
```
`config.get()` will throw an exception for undefined keys to help catch typos and missing values.
Use `config.has()` to test if a configuration value is defined.
**Start your app server:**
```shell
$ export NODE_ENV=production
$ node my-app.js
```
Running in this configuration, the `port` and `dbName` elements of `dbConfig`
will come from the `default.json` file, and the `host` element will
come from the `production.json` override file.

# JSON5 – JSON for Humans
[![Build Status](https://app.travis-ci.com/json5/json5.svg?branch=main)][Build
Status] [![Coverage
Status](https://coveralls.io/repos/github/json5/json5/badge.svg)][Coverage
Status]
JSON5 is an extension to the popular [JSON] file format that aims to be
easier to **write and maintain _by hand_ (e.g. for config files)**.
It is _not intended_ to be used for machine-to-machine communication.
(Keep using JSON or other file formats for that. 🙂)
JSON5 was started in 2012, and as of 2022, now gets **[>65M downloads/week](https://www.npmjs.com/package/json5)**,
ranks in the **[top 0.1%](https://gist.github.com/anvaka/8e8fa57c7ee1350e3491)** of the most depended-upon packages on npm,
and has been adopted by major projects like
**[Chromium](https://source.chromium.org/chromium/chromium/src/+/main:third_party/blink/renderer/platform/runtime_enabled_features.json5;drc=5de823b36e68fd99009a29281b17bc3a1d6b329c),
[Next.js](https://github.com/vercel/next.js/blob/b88f20c90bf4659b8ad5cb2a27956005eac2c7e8/packages/next/lib/find-config.ts#L43-L46),
[Babel](https://babeljs.io/docs/en/config-files#supported-file-extensions),
[Retool](https://community.retool.com/t/i-am-attempting-to-append-several-text-fields-to-a-google-sheet-but-receiving-a-json5-invalid-character-error/7626),
[WebStorm](https://www.jetbrains.com/help/webstorm/json.html),
and [more](https://github.com/json5/json5/wiki/In-the-Wild)**.
It's also natively supported on **[Apple platforms](https://developer.apple.com/documentation/foundation/jsondecoder/3766916-allowsjson5)**
like **MacOS** and **iOS**.
Formally, the **[JSON5 Data Interchange Format](https://spec.json5.org/)** is a superset of JSON
(so valid JSON files will always be valid JSON5 files)
that expands its syntax to include some productions from [ECMAScript 5.1] (ES5).
It's also a strict _subset_ of ES5, so valid JSON5 files will always be valid ES5.
This JavaScript library is a reference implementation for JSON5 parsing and serialization,
and is directly used in many of the popular projects mentioned above
(where e.g. extreme performance isn't necessary),
but others have created [many other libraries](https://github.com/json5/json5/wiki/In-the-Wild)
across many other platforms.
[Build Status]: https://app.travis-ci.com/json5/json5
[Coverage Status]: https://coveralls.io/github/json5/json5
[JSON]: https://tools.ietf.org/html/rfc7159
[ECMAScript 5.1]: https://www.ecma-international.org/ecma-262/5.1/
## Summary of Features
The following ECMAScript 5.1 features, which are not supported in JSON, have
been extended to JSON5.
### Objects
- Object keys may be an ECMAScript 5.1 _[IdentifierName]_.
- Objects may have a single trailing comma.
### Arrays
- Arrays may have a single trailing comma.
### Strings
- Strings may be single quoted.
- Strings may span multiple lines by escaping new line characters.
- Strings may include character escapes.
### Numbers
- Numbers may be hexadecimal.
- Numbers may have a leading or trailing decimal point.
- Numbers may be [IEEE 754] positive infinity, negative infinity, and NaN.
- Numbers may begin with an explicit plus sign.
### Comments
- Single and multi-line comments are allowed.
### White Space
- Additional white space characters are allowed.
[IdentifierName]: https://www.ecma-international.org/ecma-262/5.1/#sec-7.6
[IEEE 754]: http://ieeexplore.ieee.org/servlet/opac?punumber=4610933
## Example
Kitchen-sink example:
```js
{
// comments
unquoted: 'and you can quote me on that',
singleQuotes: 'I can use "double quotes" here',
lineBreaks: "Look, Mom! \
No \\n's!",
hexadecimal: 0xdecaf,
leadingDecimalPoint: .8675309, andTrailing: 8675309.,
positiveSign: +1,
trailingComma: 'in objects', andIn: ['arrays',],
"backwardsCompatible": "with JSON",
}
```
A more real-world example is [this config file](https://github.com/chromium/chromium/blob/feb3c9f670515edf9a88f185301cbd7794ee3e52/third_party/blink/renderer/platform/runtime_enabled_features.json5)
from the Chromium/Blink project.
## Specification
For a detailed explanation of the JSON5 format, please read the [official
specification](https://json5.github.io/json5-spec/).
## Installation and Usage
### Node.js
```sh
npm install json5
```
#### CommonJS
```js
const JSON5 = require('json5')
```
#### Modules
```js
import JSON5 from 'json5'
```
### Browsers
#### UMD
```html
<!-- This will create a global `JSON5` variable. -->
<script src="https://unpkg.com/json5@2/dist/index.min.js"></script>
```
#### Modules
```html
<script type="module">
import JSON5 from 'https://unpkg.com/json5@2/dist/index.min.mjs'
</script>
```
## API
The JSON5 API is compatible with the [JSON API].
[JSON API]:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON
### JSON5.parse()
Parses a JSON5 string, constructing the JavaScript value or object described by
the string. An optional reviver function can be provided to perform a
transformation on the resulting object before it is returned.
#### Syntax
JSON5.parse(text[, reviver])
#### Parameters
- `text`: The string to parse as JSON5.
- `reviver`: If a function, this prescribes how the value originally produced by
parsing is transformed, before being returned.
#### Return value
The object corresponding to the given JSON5 text.
### JSON5.stringify()
Converts a JavaScript value to a JSON5 string, optionally replacing values if a
replacer function is specified, or optionally including only the specified
properties if a replacer array is specified.
#### Syntax
JSON5.stringify(value[, replacer[, space]])
JSON5.stringify(value[, options])
#### Parameters
- `value`: The value to convert to a JSON5 string.
- `replacer`: A function that alters the behavior of the stringification
process, or an array of String and Number objects that serve as a whitelist
for selecting/filtering the properties of the value object to be included in
the JSON5 string. If this value is null or not provided, all properties of the
object are included in the resulting JSON5 string.
- `space`: A String or Number object that's used to insert white space into the
output JSON5 string for readability purposes. If this is a Number, it
indicates the number of space characters to use as white space; this number is
capped at 10 (if it is greater, the value is just 10). Values less than 1
indicate that no space should be used. If this is a String, the string (or the
first 10 characters of the string, if it's longer than that) is used as white
space. If this parameter is not provided (or is null), no white space is used.
If white space is used, trailing commas will be used in objects and arrays.
- `options`: An object with the following properties:
- `replacer`: Same as the `replacer` parameter.
- `space`: Same as the `space` parameter.
- `quote`: A String representing the quote character to use when serializing
strings.
#### Return value
A JSON5 string representing the value.
### Node.js `require()` JSON5 files
When using Node.js, you can `require()` JSON5 files by adding the following
statement.
```js
require('json5/lib/register')
```
Then you can load a JSON5 file with a Node.js `require()` statement. For
example:
```js
const config = require('./config.json5')
```
## CLI
Since JSON is more widely used than JSON5, this package includes a CLI for
converting JSON5 to JSON and for validating the syntax of JSON5 documents.
### Installation
```sh
npm install --global json5
```
### Usage
```sh
json5 [options] <file>
```
If `<file>` is not provided, then STDIN is used.
#### Options:
- `-s`, `--space`: The number of spaces to indent or `t` for tabs
- `-o`, `--out-file [file]`: Output to the specified file, otherwise STDOUT
- `-v`, `--validate`: Validate JSON5 but do not output JSON
- `-V`, `--version`: Output the version number
- `-h`, `--help`: Output usage information
## Contributing
### Development
```sh
git clone https://github.com/json5/json5
cd json5
npm install
```
When contributing code, please write relevant tests and run `npm test` and `npm
run lint` before submitting pull requests. Please use an editor that supports
[EditorConfig](http://editorconfig.org/).
### Issues
To report bugs or request features regarding the JSON5 **data format**,
please submit an issue to the official
**[_specification_ repository](https://github.com/json5/json5-spec)**.
Note that we will never add any features that make JSON5 incompatible with ES5;
that compatibility is a fundamental premise of JSON5.
To report bugs or request features regarding this **JavaScript implementation**
of JSON5, please submit an issue to **_this_ repository**.
### Security Vulnerabilities and Disclosures

## Credits
[Aseem Kishore](https://github.com/aseemk) founded this project.
He wrote a [blog post](https://aseemk.substack.com/p/ignore-the-f-ing-haters-json5)
about the journey and lessons learned 10 years in.
[Michael Bolin](http://bolinfest.com/) independently arrived at and published
some of these same ideas with awesome explanations and detail. Recommended
reading: [Suggested Improvements to JSON](http://bolinfest.com/essays/json.html)
[Douglas Crockford](http://www.crockford.com/) of course designed and built
JSON, but his state machine diagrams on the [JSON website](http://json.org/), as
cheesy as it may sound, gave us motivation and confidence that building a new
parser to implement these ideas was within reach! The original
implementation of JSON5 was also modeled directly off of Doug’s open-source
[json_parse.js] parser. We’re grateful for that clean and well-documented
code.

[Max Nanasy](https://github.com/MaxNanasy) has been an early and prolific
supporter, contributing multiple patches and ideas.
[Andrew Eisenberg](https://github.com/aeisenberg) contributed the original
`stringify` method.
[Jordan Tucker](https://github.com/jordanbtucker) has aligned JSON5 more closely
with ES5, wrote the official JSON5 specification, completely rewrote the
codebase from the ground up, and is actively maintaining this project.

Publishing
===
Use `tin` to update the version number in `package.json`.
tin -v x.y.z
Then run the publish script
./publish.sh
afterwards don't forget to update the versions to be a prerelease of the next version, so if you just published 1.1.1 then:
tin -v 1.1.2-alpha
git add package.json
git commit -m 'update version to 1.1.2-alpha'
git push origin master

## Motivation
Instead of implementing `XMLHttpRequest` in Node.js to run browser-specific [Fetch polyfill](https://github.com/github/fetch), why not go from native `http` to `fetch` API directly? Hence, `node-fetch`, minimal code for a `window.fetch` compatible API on Node.js runtime.
See Matt Andrews' [isomorphic-fetch](https://github.com/matthew-andrews/isomorphic-fetch) or Leonardo Quixada's [cross-fetch](https://github.com/lquixada/cross-fetch) for isomorphic usage (exports `node-fetch` for server-side, `whatwg-fetch` for client-side).
## Features
- Stay consistent with `window.fetch` API.
- Make conscious trade-off when following [WHATWG fetch spec][whatwg-fetch] and [stream spec](https://streams.spec.whatwg.org/) implementation details, document known differences.
- Use native promise but allow substituting it with [insert your favorite promise library].
- Use native Node streams for body on both request and response.
- Decode content encoding (gzip/deflate) properly and convert string output (such as `res.text()` and `res.json()`) to UTF-8 automatically.
- Useful extensions such as timeout, redirect limit, response size limit, [explicit errors](ERROR-HANDLING.md) for troubleshooting.
## Difference from client-side fetch
- See [Known Differences](LIMITS.md) for details.
- If you happen to use a missing feature that `window.fetch` offers, feel free to open an issue.
- Pull requests are welcomed too!
## Installation
Current stable release (`2.x`)
```sh
$ npm install node-fetch
```
## Loading and configuring the module
We suggest you load the module via `require` until the stabilization of ES modules in node:
```js
const fetch = require('node-fetch');
```
If you are using a Promise library other than native, set it through `fetch.Promise`:
```js
const Bluebird = require('bluebird');
fetch.Promise = Bluebird;
```
## Common Usage
NOTE: The documentation below is up-to-date with `2.x` releases; see the [`1.x` readme](https://github.com/bitinn/node-fetch/blob/1.x/README.md), [changelog](https://github.com/bitinn/node-fetch/blob/1.x/CHANGELOG.md) and [2.x upgrade guide](UPGRADE-GUIDE.md) for the differences.
#### Plain text or HTML
```js
fetch('https://github.com/')
.then(res => res.text())
.then(body => console.log(body));
```
#### JSON
```js
fetch('https://api.github.com/users/github')
.then(res => res.json())
.then(json => console.log(json));
```
#### Simple Post
```js
fetch('https://httpbin.org/post', { method: 'POST', body: 'a=1' })
.then(res => res.json()) // expecting a json response
.then(json => console.log(json));
```
#### Post with JSON
```js
const body = { a: 1 };
fetch('https://httpbin.org/post', {
method: 'post',
body: JSON.stringify(body),
headers: { 'Content-Type': 'application/json' },
})
.then(res => res.json())
.then(json => console.log(json));
```
#### Post with form parameters
`URLSearchParams` is available in Node.js as of v7.5.0. See [official documentation](https://nodejs.org/api/url.html#url_class_urlsearchparams) for more usage methods.
NOTE: The `Content-Type` header is only set automatically to `x-www-form-urlencoded` when an instance of `URLSearchParams` is given as such:
```js
const { URLSearchParams } = require('url');
const params = new URLSearchParams();
params.append('a', 1);
fetch('https://httpbin.org/post', { method: 'POST', body: params })
.then(res => res.json())
.then(json => console.log(json));
```
#### Handling exceptions
NOTE: 3xx-5xx responses are *NOT* exceptions and should be handled in `then()`; see the next section for more information.
Adding a catch to the fetch promise chain will catch *all* exceptions, such as errors originating from node core libraries, network errors and operational errors, which are instances of FetchError. See the [error handling document](ERROR-HANDLING.md) for more details.
```js
fetch('https://domain.invalid/')
.catch(err => console.error(err));
```
#### Handling client and server errors
It is common to create a helper function to check that the response contains no client (4xx) or server (5xx) error responses:
```js
function checkStatus(res) {
if (res.ok) { // res.status >= 200 && res.status < 300
return res;
} else {
throw MyCustomError(res.statusText);
}
}
fetch('https://httpbin.org/status/400')
.then(checkStatus)
.then(res => console.log('will not get here...'))
```
## Advanced Usage
#### Streams
The "Node.js way" is to use streams when possible:
```js
fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png')
.then(res => {
const dest = fs.createWriteStream('./octocat.png');
res.body.pipe(dest);
});
```
In Node.js 14 you can also use async iterators to read `body`; however, be careful to catch
errors -- the longer a response runs, the more likely it is to encounter an error.
```js
const fetch = require('node-fetch');
const response = await fetch('https://httpbin.org/stream/3');
try {
for await (const chunk of response.body) {
console.dir(JSON.parse(chunk.toString()));
}
} catch (err) {
console.error(err.stack);
}
```
In Node.js 12 you can also use async iterators to read `body`; however, async iterators with streams
did not mature until Node.js 14, so you need to do some extra work to ensure you handle errors
directly from the stream and wait on it response to fully close.
```js
const fetch = require('node-fetch');
const read = async body => {
let error;
body.on('error', err => {
error = err;
});
for await (const chunk of body) {
console.dir(JSON.parse(chunk.toString()));
}
return new Promise((resolve, reject) => {
body.on('close', () => {
error ? reject(error) : resolve();
});
});
};
try {
const response = await fetch('https://httpbin.org/stream/3');
await read(response.body);
} catch (err) {
console.error(err.stack);
}
```
#### Buffer
If you prefer to cache binary data in full, use buffer(). (NOTE: `buffer()` is a `node-fetch`-only API)
```js
const fileType = require('file-type');
fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png')
.then(res => res.buffer())
.then(buffer => fileType(buffer))
.then(type => { /* ... */ });
```
#### Accessing Headers and other Meta data
```js
fetch('https://github.com/')
.then(res => {
console.log(res.ok);
console.log(res.status);
console.log(res.statusText);
console.log(res.headers.raw());
console.log(res.headers.get('content-type'));
});
```
#### Extract Set-Cookie Header
Unlike browsers, you can access raw `Set-Cookie` headers manually using `Headers.raw()`. This is a `node-fetch` only API.
```js
fetch(url).then(res => {
// returns an array of values, instead of a string of comma-separated values
console.log(res.headers.raw()['set-cookie']);
});
```
#### Post data using a file stream
```js
const { createReadStream } = require('fs');
const stream = createReadStream('input.txt');
fetch('https://httpbin.org/post', { method: 'POST', body: stream })
.then(res => res.json())
.then(json => console.log(json));
```
#### Post with form-data (detect multipart)
```js
const FormData = require('form-data');
const form = new FormData();
form.append('a', 1);
fetch('https://httpbin.org/post', { method: 'POST', body: form })
.then(res => res.json())
.then(json => console.log(json));
// OR, using custom headers
// NOTE: getHeaders() is non-standard API
const form = new FormData();
form.append('a', 1);
const options = {
method: 'POST',
body: form,
headers: form.getHeaders()
}
fetch('https://httpbin.org/post', options)
.then(res => res.json())
.then(json => console.log(json));
```
#### Request cancellation with AbortSignal
> NOTE: You may cancel streamed requests only on Node >= v8.0.0
You may cancel requests with `AbortController`. A suggested implementation is [`abort-controller`](https://www.npmjs.com/package/abort-controller).
An example of timing out a request after 150ms could be achieved as the following:
```js
import AbortController from 'abort-controller';
const controller = new AbortController();
const timeout = setTimeout(
() => { controller.abort(); },
150,
);
fetch(url, { signal: controller.signal })
.then(res => res.json())
.then(
data => {
useData(data)
},
err => {
if (err.name === 'AbortError') {
// request was aborted
}
},
)
.finally(() => {
clearTimeout(timeout);
});
```
See [test cases](https://github.com/bitinn/node-fetch/blob/master/test/test.js) for more examples.
## API
### fetch(url[, options])
- `url` A string representing the URL for fetching
- `options` [Options](#fetch-options) for the HTTP(S) request
- Returns: <code>Promise&lt;[Response](#class-response)&gt;</code>
Perform an HTTP(S) fetch.
`url` should be an absolute url, such as `https://example.com/`. A path-relative URL (`/file/under/root`) or protocol-relative URL (`//can-be-http-or-https.com/`) will result in a rejected `Promise`.
<a id="fetch-options"></a>
### Options
The default values are shown after each option key.
```js
{
// These properties are part of the Fetch Standard
method: 'GET',
headers: {}, // request headers. format is the identical to that accepted by the Headers constructor (see below)
body: null, // request body. can be null, a string, a Buffer, a Blob, or a Node.js Readable stream
redirect: 'follow', // set to `manual` to extract redirect headers, `error` to reject redirect
signal: null, // pass an instance of AbortSignal to optionally abort requests
// The following properties are node-fetch extensions
follow: 20, // maximum redirect count. 0 to not follow redirect
timeout: 0, // req/res timeout in ms, it resets on redirect. 0 to disable (OS limit applies). Signal is recommended instead.
compress: true, // support gzip/deflate content encoding. false to disable
size: 0, // maximum response body size in bytes. 0 to disable
agent: null // http(s).Agent instance or function that returns an instance (see below)
}
```
##### Default Headers
If no values are set, the following request headers will be sent automatically:
Header | Value
------------------- | --------------------------------------------------------
`Accept-Encoding` | `gzip,deflate` _(when `options.compress === true`)_
`Accept` | `*/*`
`Connection` | `close` _(when no `options.agent` is present)_
`Content-Length` | _(automatically calculated, if possible)_
`Transfer-Encoding` | `chunked` _(when `req.body` is a stream)_
`User-Agent` | `node-fetch/1.0 (+https://github.com/bitinn/node-fetch)`
Note: when `body` is a `Stream`, `Content-Length` is not set automatically.
##### Custom Agent
The `agent` option allows you to specify networking related options which are out of the scope of Fetch, including and not limited to the following:
- Support self-signed certificate
- Use only IPv4 or IPv6
- Custom DNS Lookup
See [`http.Agent`](https://nodejs.org/api/http.html#http_new_agent_options) for more information.
In addition, the `agent` option accepts a function that returns `http`(s)`.Agent` instance given current [URL](https://nodejs.org/api/url.html), this is useful during a redirection chain across HTTP and HTTPS protocol.
```js
const httpAgent = new http.Agent({
keepAlive: true
});
const httpsAgent = new https.Agent({
keepAlive: true
});
const options = {
agent: function (_parsedURL) {
if (_parsedURL.protocol == 'http:') {
return httpAgent;
} else {
return httpsAgent;
}
}
}
```
<a id="class-request"></a>
### Class: Request
An HTTP(S) request containing information about URL, method, headers, and the body. This class implements the [Body](#iface-body) interface.
Due to the nature of Node.js, the following properties are not implemented at this moment:
- `type`
- `destination`
- `referrer`
- `referrerPolicy`
- `mode`
- `credentials`
- `cache`
- `integrity`
- `keepalive`
The following node-fetch extension properties are provided:
- `follow`
- `compress`
- `counter`
- `agent`
See [options](#fetch-options) for exact meaning of these extensions.
#### new Request(input[, options])
<small>*(spec-compliant)*</small>
- `input` A string representing a URL, or another `Request` (which will be cloned)
- `options` [Options][#fetch-options] for the HTTP(S) request
Constructs a new `Request` object. The constructor is identical to that in the [browser](https://developer.mozilla.org/en-US/docs/Web/API/Request/Request).
In most cases, directly `fetch(url, options)` is simpler than creating a `Request` object.
<a id="class-response"></a>
### Class: Response
An HTTP(S) response. This class implements the [Body](#iface-body) interface.
The following properties are not implemented in node-fetch at this moment:
- `Response.error()`
- `Response.redirect()`
- `type`
- `trailer`
#### new Response([body[, options]])
<small>*(spec-compliant)*</small>
- `body` A `String` or [`Readable` stream][node-readable]
- `options` A [`ResponseInit`][response-init] options dictionary
Constructs a new `Response` object. The constructor is identical to that in the [browser](https://developer.mozilla.org/en-US/docs/Web/API/Response/Response).
Because Node.js does not implement service workers (for which this class was designed), one rarely has to construct a `Response` directly.
#### response.ok
<small>*(spec-compliant)*</small>
Convenience property representing if the request ended normally. Will evaluate to true if the response status was greater than or equal to 200 but smaller than 300.
#### response.redirected
<small>*(spec-compliant)*</small>
Convenience property representing if the request has been redirected at least once. Will evaluate to true if the internal redirect counter is greater than 0.
<a id="class-headers"></a>
### Class: Headers
This class allows manipulating and iterating over a set of HTTP headers. All methods specified in the [Fetch Standard][whatwg-fetch] are implemented.
#### new Headers([init])
<small>*(spec-compliant)*</small>
- `init` Optional argument to pre-fill the `Headers` object
Construct a new `Headers` object. `init` can be either `null`, a `Headers` object, an key-value map object or any iterable object.
```js
// Example adapted from https://fetch.spec.whatwg.org/#example-headers-class
const meta = {
'Content-Type': 'text/xml',
'Breaking-Bad': '<3'
};
const headers = new Headers(meta);
// The above is equivalent to
const meta = [
[ 'Content-Type', 'text/xml' ],
[ 'Breaking-Bad', '<3' ]
];
const headers = new Headers(meta);
// You can in fact use any iterable objects, like a Map or even another Headers
const meta = new Map();
meta.set('Content-Type', 'text/xml');
meta.set('Breaking-Bad', '<3');
const headers = new Headers(meta);
const copyOfHeaders = new Headers(headers);
```
<a id="iface-body"></a>
### Interface: Body
`Body` is an abstract interface with methods that are applicable to both `Request` and `Response` classes.
The following methods are not yet implemented in node-fetch at this moment:
- `formData()`
#### body.body
<small>*(deviation from spec)*</small>
* Node.js [`Readable` stream][node-readable]
Data are encapsulated in the `Body` object. Note that while the [Fetch Standard][whatwg-fetch] requires the property to always be a WHATWG `ReadableStream`, in node-fetch it is a Node.js [`Readable` stream][node-readable].
#### body.bodyUsed
<small>*(spec-compliant)*</small>
* `Boolean`
A boolean property for if this body has been consumed. Per the specs, a consumed body cannot be used again.
#### body.arrayBuffer()
#### body.blob()
#### body.json()
#### body.text()
<small>*(spec-compliant)*</small>
* Returns: <code>Promise</code>
Consume the body and return a promise that will resolve to one of these formats.
#### body.buffer()
<small>*(node-fetch extension)*</small>
* Returns: <code>Promise&lt;Buffer&gt;</code>
Consume the body and return a promise that will resolve to a Buffer.
#### body.textConverted()
<small>*(node-fetch extension)*</small>
* Returns: <code>Promise&lt;String&gt;</code>
Identical to `body.text()`, except instead of always converting to UTF-8, encoding sniffing will be performed and text converted to UTF-8 if possible.
(This API requires an optional dependency of the npm package [encoding](https://www.npmjs.com/package/encoding), which you need to install manually. `webpack` users may see [a warning message](https://github.com/bitinn/node-fetch/issues/412#issuecomment-379007792) due to this optional dependency.)
<a id="class-fetcherror"></a>
### Class: FetchError
<small>*(node-fetch extension)*</small>
An operational error in the fetching process. See [ERROR-HANDLING.md][] for more info.
<a id="class-aborterror"></a>
### Class: AbortError
<small>*(node-fetch extension)*</small>
An Error thrown when the request is aborted in response to an `AbortSignal`'s `abort` event. It has a `name` property of `AbortError`. See [ERROR-HANDLING.MD][] for more info.

Publishing
===
Make sure you have the latest from the main branch:
git pull origin master
Use `tin` to update the version number in the `package.json`, `component.json` & `bower.json`.
tin -v x.y.z
Then run the publish script
./publish.sh
afterwards don't forget to update the versions to be a prerelease of the next version, so if you just published 1.1.1 then:
tin -v 1.1.2-alpha
git add package.json component.json bower.json
git commit -m 'update version to 1.1.2-alpha'
git push origin master

# PROJ4JS [![Build Status](https://api.travis-ci.org/proj4js/proj4js.svg?branch=master)](https://travis-ci.org/proj4js/proj4js)
Proj4js is a JavaScript library to transform point coordinates from one coordinate system to another, including datum transformations.
Originally a port of [PROJ](https://proj.org/) ([then known as PROJ.4](https://proj.org/faq.html#what-happened-to-proj-4)) and GCTCP C ([Archive](https://web.archive.org/web/20130523091752/http://edcftp.cr.usgs.gov/pub/software/gctpc/)) it is
a part of the [MetaCRS](https://trac.osgeo.org/metacrs/wiki) group of projects.
## Installing
Depending on your preferences
```bash
npm install proj4
bower install proj4
component install proj4js/proj4js
```
or just manually grab the file `proj4.js` from the [latest release](https://github.com/proj4js/proj4js/releases)'s `dist/` folder.
If you do not want to download anything, Proj4js is also hosted on [cdnjs](https://www.cdnjs.com/libraries/proj4js) for direct use in your browser applications.
## Using
The basic signature is:
```javascript
proj4([fromProjection, ]toProjection[, coordinates])
```
Projections can be proj or wkt strings.
Coordinates may be an object of the form `{x:x,y:y}` or an array of the form `[x,y]`.
When all 3 arguments are given, the result is that the coordinates are transformed from projection1 to projection 2. And returned in the same format that they were given in.
```javascript
var firstProjection = 'PROJCS["NAD83 / Massachusetts Mainland",GEOGCS["NAD83",DATUM["North_American_Datum_1983",SPHEROID["GRS 1980",6378137,298.257222101,AUTHORITY["EPSG","7019"]],AUTHORITY["EPSG","6269"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.01745329251994328,AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4269"]],UNIT["metre",1,AUTHORITY["EPSG","9001"]],PROJECTION["Lambert_Conformal_Conic_2SP"],PARAMETER["standard_parallel_1",42.68333333333333],PARAMETER["standard_parallel_2",41.71666666666667],PARAMETER["latitude_of_origin",41],PARAMETER["central_meridian",-71.5],PARAMETER["false_easting",200000],PARAMETER["false_northing",750000],AUTHORITY["EPSG","26986"],AXIS["X",EAST],AXIS["Y",NORTH]]';
var secondProjection = "+proj=gnom +lat_0=90 +lon_0=0 +x_0=6300000 +y_0=6300000 +ellps=WGS84 +datum=WGS84 +units=m +no_defs";
//I'm not going to redefine those two in latter examples.
proj4(firstProjection,secondProjection,[-122.305887, 58.9465872]);
// [-2690575.447893817, 36622916.8071244564]
```
The library can also parse coordinates provided with an elevation and measure, again as an object of the form `{x:x,y:y,z:z,m:m}` or an array of the form `[x,y,z,m]`.
```javascript
proj4(firstProjection,secondProjection,[-122.305887, 58.9465872,10]);
// [-2690575.447893817, 36622916.8071244564, 10]
```
If only 1 projection is given then it is assumed that it is being projected *from* WGS84 (fromProjection is WGS84).
```javascript
proj4(firstProjection,[-71,41]);
// [242075.00535055372, 750123.32090043]
```
If no coordinates are given an object with two methods is returned, its methods are `forward` which projects from the first projection to the second and `inverse` which projects from the second to the first.
```javascript
proj4(firstProjection,secondProjection).forward([-122.305887, 58.9465872]);
// [-2690575.447893817, 36622916.8071244564]
proj4(secondProjection,firstProjection).inverse([-122.305887, 58.9465872]);
// [-2690575.447893817, 36622916.8071244564]
```
And as above if only one projection is given, it's assumed to be coming from wgs84:
```javascript
proj4(firstProjection).forward([-71,41]);
// [242075.00535055372, 750123.32090043]
proj4(firstProjection).inverse([242075.00535055372, 750123.32090043]);
// [-71, 40.99999999999986]
```
Note: The generation of the floating point value `40.99999999999986` in this example represents the fact that some variance in precision is involved in any conversion between one coordinate reference system and another.
## Named Projections
If you prefer to define a projection as a string and reference it that way, you may use the proj4.defs method which can be called 2 ways, with a name and projection:
```js
proj4.defs('WGS84', "+title=WGS 84 (long/lat) +proj=longlat +ellps=WGS84 +datum=WGS84 +units=degrees");
```
or with an array
```js
proj4.defs([
[
'EPSG:4326',
'+title=WGS 84 (long/lat) +proj=longlat +ellps=WGS84 +datum=WGS84 +units=degrees'],
[
'EPSG:4269',
'+title=NAD83 (long/lat) +proj=longlat +a=6378137.0 +b=6356752.31414036 +ellps=GRS80 +datum=NAD83 +units=degrees'
]
]);
```
you can then do
```js
proj4('EPSG:4326');
```
instead of writing out the whole proj definition, by default proj4 has the following projections predefined:
- 'EPSG:4326', which has the following alias
- 'WGS84'
- 'EPSG:4269'
- 'EPSG:3857', which has the following aliases
- 'EPSG:3785'
- 'GOOGLE'
- 'EPSG:900913'
- 'EPSG:102113'
Defined projections can also be accessed through the proj4.defs function (`proj4.defs('EPSG:4326')`).
proj4.defs can also be used to define a named alias:
```javascript
proj4.defs('urn:x-ogc:def:crs:EPSG:4326', proj4.defs('EPSG:4326'));
```
## Axis order
By default, proj4 uses `[x,y]` axis order for projected (cartesian) coordinate systems and `[x=longitude,y=latitude]` for geographic coordinates. To enforce the axis order of the provided proj or wkt string, use the
```javascript
proj4(fromProjection, toProjection).forward(coordinate, enforceAxis);
proj4(fromProjection, toProjection).inverse(coordinate, enforceAxis);
```
signatures with `enforceAxis` set to `true`:
```javascript
proj4('+proj=longlat +ellps=WGS84 +datum=WGS84 +units=degrees +axis=neu', firstProjection).forward([41, -71], true);
// [242075.00535055372, 750123.32090043]
proj4('+proj=longlat +ellps=WGS84 +datum=WGS84 +units=degrees +axis=neu', firstProjection).inverse([242075.00535055372, 750123.32090043], true);
//[40.99999999999986, -71]
//the floating points to answer your question
```
## Grid Based Datum Adjustments
To use `+nadgrids=` in a proj definition, first read your NTv2 `.gsb` file (e.g. from https://github.com/OSGeo/proj-datumgrid) into an ArrayBuffer, then pass it to `proj4.nadgrid`. E.g:
```javascript
const buffer = fs.readFileSync('ntv2.gsb').buffer
proj4.nadgrid('key', buffer);
```
then use the given key in your definition, e.g. `+nadgrids=@key,null`. See [Grid Based Datum Adjustments](https://proj.org/usage/transformation.html?highlight=nadgrids#grid-based-datum-adjustments).
## TypeScript
TypeScript implementation was added to the [DefinitelyTyped repository](https://github.com/DefinitelyTyped/DefinitelyTyped).
```bash
$ npm install --save @types/proj4
```
## Developing
To set up build tools make sure you have node and grunt-cli installed and then run `npm install`.
To do the complete build and browser tests run
```bash
node_modules/.bin/grunt
```
To run node tests run
```bash
npm test
```
To run node tests with coverage run
```bash
npm test --coverage
```
To create a build with only default projections (latlon and Mercator) run
```bash
node_modules/.bin/grunt build
```
To create a build with only custom projections include a comma separated list of projections codes (the file name in 'lib/projections' without the '.js') after a colon, e.g.
```bash
node_modules/.bin/grunt build:tmerc
#includes transverse Mercator
node_modules/.bin/grunt build:lcc
#includes lambert conformal conic
node_modules/.bin/grunt build:omerc,moll
#includes oblique Mercator and Mollweide
```

- 2.1.4: dist folder is added back in after accidentally omitting it in 2.1.1
- 2.1.3: skipped as issues with the dist folder are ironed out.
- 2.1.2: added sensible defaults for false eastings/northings
- 2.1.1: tweaks to how we publish it, fixes related to errors with the OSGB36 and Reseau National Belge 1972 datums, we took the first steps towards depreciating the proj4.Point class.
- 2.1.0: targeted builds for projections are now supported, and internally projection creation is more modular.
- 2.0.3: mgrs is broken out into it's own module loaded via npm.
- 2.0.2: module common is broken up into a collection of smaller modules.
- 2.0.1: fix typo in eqc projection.
- 2.0.0: we start the change log.
