+================
+
+[![CI](https://github.com/nodeca/probe-image-size/actions/workflows/ci.yml/badge.svg)](https://github.com/nodeca/probe-image-size/actions)
+[![NPM version](https://img.shields.io/npm/v/probe-image-size.svg?style=flat)](https://www.npmjs.org/package/probe-image-size)
+[![Coverage Status](https://coveralls.io/repos/github/nodeca/probe-image-size/badge.svg?branch=master)](https://coveralls.io/github/nodeca/probe-image-size?branch=master)
+
+> Get image size without full download. Supported image types:
+> JPG, GIF, PNG, WebP, BMP, TIFF, SVG, PSD, ICO, AVIF, HEIC, HEIF.
+
+Key features:
+
+- small size, no heavy dependencies
+- works with remote and local data
+- effective with big images (speed/memory), download minimal data from remotes
+- extracts orientation value when available
+- easy to browserify (splitted to components)
+
+
+Install
+-------
+
+```bash
+npm install probe-image-size
+```
+
+Example
+-------
+
+```js
+const probe = require('probe-image-size');
+
+// Get by URL
+let result = await probe('http://example.com/image.jpg');
+console.log(result); // =>
+/*
+  {
+    width: xx,
+    height: yy,
+    type: 'jpg',
+    mime: 'image/jpeg',
+    wUnits: 'px',
+    hUnits: 'px',
+    url: 'http://example.com/image.jpg'
+  }
+*/
+
+
+// By URL with options
+let result = await probe('http://example.com/image.jpg', { rejectUnauthorized: false });
+console.log(result);
+
+
+// From the stream
+let result = await probe(require('fs').createReadStream('image.jpg'));
+console.log(result);
+
+
+// From a Buffer (sync)
+let data = require('fs').readFileSync('image.jpg');
+console.log(probe.sync(data));
+```
+
+
+API
+---
+
+Note:
+
+- You can access/browserify `stream.js` / `http.js` / `sync.js` directly.
+- If you don't like `http.js` dependencies, you can create your own wrapper
+  for `stream.js`.
+
+### probe(src [, options|keepOpen]) -> Promise
+
+- `src` can be of this types:
+  - _String_ - URL to fetch
+  - _Stream_ - readable stream
+- `options` - HTTP only. See [`needle` documentation](https://github.com/tomas/needle#request-options), and customized [defaults](https://github.com/nodeca/probe-image-size/blob/master/http.js#L13).
+- `keepOpen` (Boolean) - stream only. Keep stream open after parser finishes
+  (input stream will be closed by default)
+
+`result` (Promise) contains:
+
+```js
+{
+  width: XX,
+  height: YY,
+  length: ZZ,   // byte length of the file (if available, HTTP only)
+  type: ...,    // image 'type' (usual file name extention)
+  mime: ...,    // mime type
+  wUnits: 'px', // width units type ('px' by default, can be different for SVG)
+  hUnits: 'px', // height units type ('px' by default, can be different for SVG)
+  url: ...,     // HTTP only, last url for the image in chain of redirects
+                // (if no redirects, same as src)
+
+  // optional, image orientation (from Exif), number from 1 to 8;
+  // you may wish to swap width and height if orientation is >= 5
+  orientation: X,
+
+  // optional, full list of sizes for ICO (always) and AVIF (if multiple images)
+  variants: [ { width, height }, ... ] | undefined
+}
+```
+
+Width and height in the output object represent image size *before* any transformations
+(orientation, cropping) are applied. Orientation is returned separately, which you may
+wish to apply afterwards depending on browser support (browsers
+[only support JPEG](https://zpl.fi/exif-orientation-in-different-formats/) orientation for now).
+See [known issues](known_issues.md) for details.
+
+> [!WARNING]
+>
+> For untrusted sources, returned `width` and `height` should not be treated
+> as trusted values. You may need to additionally check that they are within
+> ranges acceptable for your application.
+
+Returned errors can be extended with 2 fields:
+
+- `code` - equals to `ECONTENT` if the library failed to parse the file;
+- `status` - equals to a HTTP status code if it receives a non-200 response.
+
+
+### probe.sync(src) -> result|null
+
+Sync version can eat arrays, typed arrays and buffers. On success it returns
+the same result as async version. On fail it returns null.
+
+> [!NOTE]
+>
+> Formats like JPEG & TIFF can store size anywhere (far from the head).
+> That usually does not happens, but if you need guarantees - always provide
+> full file content to sync methods. We strongly recommend to use async version
+> as memory-friendly.

+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+  debug(req.method + ' ' + req.url);
+  res.end('hello\n');
+}).listen(3000, function(){
+  debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+  , b = require('debug')('worker:b');
+
+function work() {
+  a('doing lots of uninteresting work');
+  setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+  b('doing some work');
+  setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:

+
+#### Windows command prompt notes
+
+##### CMD
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Example:
+
+```cmd
+set DEBUG=* & node app.js
+```
+
+##### PowerShell (VS Code default)
+
+PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Example:
+
+```cmd
+$env:DEBUG='app';node app.js
+```
+
+Then, run the program to be debugged as usual.
+
+npm script example:
+```js
+  "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
+```
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".  If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable.  You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name      | Purpose                                         |
+|-----------|-------------------------------------------------|
+| `DEBUG`   | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY).  |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth.                    |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O`      | Pretty-print an Object on multiple lines. |
+| `%o`      | Pretty-print an Object all on a single line. |
+| `%s`      | String. |
+| `%d`      | Number (both integer and float). |
+| `%j`      | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%`      | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+  return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+//   foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+  a('doing some work');
+}, 1000);
+
+setInterval(function(){
+  b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Extend
+You can simply extend debugger 
+```js
+const log = require('debug')('auth');
+
+//creates new debug instance with extended namespace
+const logSign = log.extend('sign');
+const logLogin = log.extend('login');
+
+log('hello'); // auth hello
+logSign('hello'); //auth:sign hello
+logLogin('hello'); //auth:login hello
+```
+
+## Set dynamically
+
+You can also enable debug dynamically by calling the `enable()` method :
+
+```js
+let debug = require('debug');
+
+console.log(1, debug.enabled('test'));
+
+debug.enable('test');
+console.log(2, debug.enabled('test'));
+
+debug.disable();
+console.log(3, debug.enabled('test'));
+
+```
+
+print :   
+```
+1 false
+2 true
+3 false
+```
+
+Usage :  
+`enable(namespaces)`  
+`namespaces` can include modes separated by a colon and wildcards.
+   
+Note that calling `enable()` completely overrides previously set DEBUG variable : 
+
+```
+$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
+=> false
+```
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+  // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

+// that triggers a 'done' event when the request/response process is complete.
+needle
+  .post('https://my.server.com/foo', data, { multipart: true })
+  .on('readable', function() { /* eat your chunks */ })
+  .on('done', function(err) {
+    console.log('Ready-o!');
+  })
+```
+
+From version 2.0.x up, Promises are also supported. Just call `needle()` directly and you'll get a native Promise object.
+
+```js
+needle('put', 'https://hacking.the.gibson/login', { password: 'god' }, { json: true })
+  .then(function(response) {
+    return doSomethingWith(response)
+  })
+  .catch(function(err) {
+    console.log('Call the locksmith!')
+  })
+```
+
+With only two real dependencies, Needle supports:
+
+ - HTTP/HTTPS requests, with the usual verbs you would expect
+ - All of Node's native TLS options, such as 'rejectUnauthorized' (see below)
+ - Basic & Digest authentication with auto-detection
+ - Multipart form-data (e.g. file uploads)
+ - HTTP Proxy forwarding, optionally with authentication
+ - Streaming gzip, deflate, and brotli decompression
+ - Automatic XML & JSON parsing
+ - 301/302/303 redirect following, with fine-grained tuning, and
+ - Streaming non-UTF-8 charset decoding, via `iconv-lite`
+
+And yes, Mr. Wayne, it does come in black.
+
+This makes Needle an ideal alternative for performing quick HTTP requests in Node, either for API interaction, downloading or uploading streams of data, and so on. If you need OAuth, AWS support or anything fancier, you should check out mikeal's request module.
+
+Install
+-------
+
+```
+$ npm install needle
+```
+
+Usage
+-----
+
+```js
+// using promises
+needle('get', 'https://server.com/posts/123')
+  .then(function(resp) {
+    // ...
+  })
+  .catch(function(err) {
+    // ...
+  });
+
+// with callback
+needle.get('ifconfig.me/all.json', function(error, response, body) {
+  if (error) throw error;
+
+  // body is an alias for `response.body`,
+  // that in this case holds a JSON-decoded object.
+  console.log(body.ip_addr);
+});
+
+// no callback, using streams
+needle.get('https://google.com/images/logo.png')
+  .pipe(fs.createWriteStream('logo.png'))
+  .on('done', function(err) {
+    console.log('Pipe finished!');
+  });
+```
+
+As you can see, you can use Needle with Promises or without them. When using Promises or when a callback is passed, the response's body will be buffered and written to `response.body`, and the callback will be fired when all of the data has been collected and processed (e.g. decompressed, decoded and/or parsed).
+
+When no callback is passed, however, the buffering logic will be skipped but the response stream will still go through Needle's processing pipeline, so you get all the benefits of post-processing while keeping the streamishness we all love from Node.
+
+Response pipeline
+-----------------
+
+Depending on the response's Content-Type, Needle will either attempt to parse JSON or XML streams, or, if a text response was received, will ensure that the final encoding you get is UTF-8.
+
+You can also request a gzip/deflated/brotli response, which, if sent by the server, will be processed before parsing or decoding is performed. (Note: brotli is only supported on Node 10.16.0 or above, and will not be requested or processed on earlier versions.)
+
+```js
+needle.get('http://stackoverflow.com/feeds', { compressed: true }, function(err, resp) {
+  console.log(resp.body); // this little guy won't be a Gzipped binary blob
+                          // but a nice object containing all the latest entries
+});
+```
+
+Or in anti-callback mode, using a few other options:
+
+```js
+var options = {
+  compressed         : true, // sets 'Accept-Encoding' to 'gzip, deflate, br'
+  follow_max         : 5,    // follow up to five redirects
+  rejectUnauthorized : true  // verify SSL certificate
+}
+
+var stream = needle.get('https://backend.server.com/everything.html', options);
+
+// read the chunks from the 'readable' event, so the stream gets consumed.
+stream.on('readable', function() {
+  while (data = this.read()) {
+    console.log(data.toString());
+  }
+})
+
+stream.on('done', function(err) {
+  // if our request had an error, our 'done' event will tell us.
+  if (!err) console.log('Great success!');
+})
+```
+
+API
+---
+
+### needle(method, url[, data][, options][, callback]) `(> 2.0.x)`
+
+Calling `needle()` directly returns a Promise. Besides `method` and `url`, all parameters are optional, although when sending a `post`, `put` or `patch` request you will get an error if `data` is not present.
+
+```js
+needle('get', 'http://some.url.com')
+  .then(function(resp) { console.log(resp.body) })
+  .catch(function(err) { console.error(err) })
+```
+
+Except from the above, all of Needle's request methods return a Readable stream, and both `options` and `callback` are optional. If passed, the callback will return three arguments: `error`, `response` and `body`, which is basically an alias for `response.body`.
+
+### needle.head(url[, options][, callback])
+
+```js
+needle.head('https://my.backend.server.com', {
+  open_timeout: 5000 // if we're not able to open a connection in 5 seconds, boom.
+}, function(err, resp) {
+  if (err)
+    console.log('Shoot! Something is wrong: ' + err.message)
+  else
+    console.log('Yup, still alive.')
+})
+```
+
+### needle.get(url[, options][, callback])
+
+```js
+needle.get('google.com/search?q=syd+barrett', function(err, resp) {
+  // if no http:// is found, Needle will automagically prepend it.
+});
+```
+
+### needle.post(url, data[, options][, callback])
+
+```js
+var options = {
+  headers: { 'X-Custom-Header': 'Bumbaway atuna' }
+}
+
+needle.post('https://my.app.com/endpoint', 'foo=bar', options, function(err, resp) {
+  // you can pass params as a string or as an object.
+});
+```
+
+### needle.put(url, data[, options][, callback])
+
+```js
+var nested = {
+  params: {
+    are: {
+      also: 'supported'
+    }
+  }
+}
+
+needle.put('https://api.app.com/v2', nested, function(err, resp) {
+  console.log('Got ' + resp.bytes + ' bytes.') // another nice treat from this handsome fella.
+});
+```
+
+### needle.patch(url, data[, options][, callback])
+
+Same behaviour as PUT.
+
+### needle.delete(url, data[, options][, callback])
+
+```js
+var options = {
+  username: 'fidelio',
+  password: 'x'
+}
+
+needle.delete('https://api.app.com/messages/123', null, options, function(err, resp) {
+  // in this case, data may be null, but you need to explicity pass it.
+});
+```
+
+### needle.request(method, url, data[, options][, callback])
+
+Generic request. This not only allows for flexibility, but also lets you perform a GET request with data, in which case will be appended to the request as a query string, unless you pass a `json: true` option (read below).
+
+```js
+var params = {
+  q    : 'a very smart query',
+  page : 2
+}
+
+needle.request('get', 'forum.com/search', params, function(err, resp) {
+  if (!err && resp.statusCode == 200)
+    console.log(resp.body); // here you go, mister.
+});
+```
+
+Now, if you set pass `json: true` among the options, Needle won't set your params as a querystring but instead send a JSON representation of your data through the request's body, as well as set the `Content-Type` and `Accept` headers to `application/json`.
+
+```js
+needle.request('get', 'forum.com/search', params, { json: true }, function(err, resp) {
+  if (resp.statusCode == 200) console.log('It worked!');
+});
+```
+
+Events
+------
+
+The [Readable stream](https://nodejs.org/api/stream.html#stream_class_stream_readable) object returned by the above request methods emits the following events, in addition to the regular ones (e.g. `end`, `close`, `data`, `pipe`, `readable`).
+
+### Event: `'response'`
+
+ - `response <http.IncomingMessage>`
+
+Emitted when the underlying [http.ClientRequest](https://nodejs.org/api/http.html#http_class_http_clientrequest) emits a response event. This is after the connection is established and the header received, but before any of it is processed (e.g. authorization required or redirect to be followed). No data has been consumed at this point.
+
+### Event: `'redirect'`
+
+ - `location <String>`
+
+Indicates that the a redirect is being followed. This means that the response code was a redirect (`301`, `302`, `303`, `307`) and the given [redirect options](#redirect-options) allowed following the URL received in the `Location` header.
+
+### Event: `'header'`
+
+ - `statusCode <Integer>`
+ - `headers <Object>`
+
+Triggered after the header has been processed, and just before the data is to be consumed. This implies that no redirect was followed and/or authentication header was received. In other words, we got a "valid" response.
+
+### Event: `'done'` (previously 'end')
+
+ - `exception <Error>` (optional)
+
+Emitted when the request/response process has finished, either because all data was consumed or an error ocurred somewhere in between. Unlike a regular stream's `end` event, Needle's `done` will be fired either on success or on failure, which is why the first argument may be an Error object. In other words:
+
+```js
+var resp = needle.get('something.worthy/of/being/streamed/by/needle');
+resp.pipe(someWritableStream);
+
+resp.on('done', function(err) {
+  if (err) console.log('An error ocurred: ' + err.message);
+  else console.log('Great success!');
+})
+```
+
+### Event: `'err'`
+
+ - `exception <Error>`
+
+Emitted when an error ocurrs. This should only happen once in the lifecycle of a Needle request.
+
+### Event: `'timeout'`
+
+ - `type <String>`
+
+Emitted when an timeout error occurs. Type can be either 'open', 'response', or 'read'. This will called right before aborting the request, which will also trigger an `err` event, a described above, with an `ECONNRESET` (Socket hang up) exception.
+
+Request options
+---------------
+
+For information about options that've changed, there's always [the changelog](https://github.com/tomas/needle/releases).
+
+ - `agent`       : Uses an [http.Agent](https://nodejs.org/api/http.html#http_class_http_agent) of your choice, instead of the global, default one. Useful for tweaking the behaviour at the connection level, such as when doing tunneling (see below for an example).
+ - `json`        : When `true`, sets content type to `application/json` and sends request body as JSON string, instead of a query string.
+ - `open_timeout`: (or `timeout`) Returns error if connection takes longer than X milisecs to establish. Defaults to `10000` (10 secs). `0` means no timeout.
+ - `response_timeout`: Returns error if no response headers are received in X milisecs, counting from when the connection is opened. Defaults to `0` (no response timeout).
+ - `read_timeout`: Returns error if data transfer takes longer than X milisecs, once response headers are received. Defaults to `0` (no timeout).
+ - `follow_max`  : (or `follow`) Number of redirects to follow. Defaults to `0`. See below for more redirect options.
+ - `multipart`   : Enables multipart/form-data encoding. Defaults to `false`. Use it when uploading files.
+ - `proxy`       : Forwards request through HTTP(s) proxy. Eg. `proxy: 'http://user:pass@proxy.server.com:3128'`. For more advanced proxying/tunneling use a custom `agent`, as described below.
+ - `headers`     : Object containing custom HTTP headers for request. Overrides defaults described below.
+ - `auth`        : Determines what to do with provided username/password. Options are `auto`, `digest` or `basic` (default). `auto` will detect the type of authentication depending on the response headers.
+ - `stream_length`: When sending streams, this lets you manually set the Content-Length header --if the stream's bytecount is known beforehand--, preventing ECONNRESET (socket hang up) errors on some servers that misbehave when receiving payloads of unknown size. Set it to `0` and Needle will get and set the stream's length for you, or leave unset for the default behaviour, which is no Content-Length header for stream payloads.
+ - `localAddress`: <string>, IP address. Passed to http/https request. Local interface from which the request should be emitted.
+ - `uri_modifier`: Anonymous function taking request (or redirect location if following redirects) URI as an argument and modifying it given logic. It has to return a valid URI string for successful request.
+
+Response options
+----------------
+
+ - `decode_response` : (or `decode`) Whether to decode the text responses to UTF-8, if Content-Type header shows a different charset. Defaults to `true`.
+ - `parse_response`  : (or `parse`) Whether to parse XML or JSON response bodies automagically. Defaults to `true`. You can also set this to 'xml' or 'json' in which case Needle will *only* parse the response if the content type matches.
+ - `output`          : Dump response output to file. This occurs after parsing and charset decoding is done.
+ - `parse_cookies`   : Whether to parse response’s `Set-Cookie` header. Defaults to `true`. If parsed, response cookies will be available at `resp.cookies`.
+
+HTTP Header options
+-------------------
+
+These are basically shortcuts to the `headers` option described above.
+
+ - `cookies`   : Builds and sets a Cookie header from a `{ key: 'value' }` object.
+ - `compressed`: If `true`, sets 'Accept-Encoding' header to 'gzip,deflate', and inflates content if zipped. Defaults to `false`.
+ - `username`  : For HTTP basic auth.
+ - `password`  : For HTTP basic auth. Requires username to be passed, but is optional.
+ - `accept`    : Sets 'Accept' HTTP header. Defaults to `*/*`.
+ - `connection`: Sets 'Connection' HTTP header. Not set by default, unless running Node < 0.11.4 in which case it defaults to `close`. More info about this below.
+ - `user_agent`: Sets the 'User-Agent' HTTP header. Defaults to `Needle/{version} (Node.js {node_version})`.
+ - `content_type`: Sets the 'Content-Type' header. Unset by default, unless you're sending data in which case it's set accordingly to whatever is being sent (`application/x-www-form-urlencoded`, `application/json` or `multipart/form-data`). That is, of course, unless the option is passed, either here or through `options.headers`. You're the boss.
+
+Node.js TLS Options
+-------------------
+
+These options are passed directly to `https.request` if present. Taken from the [original documentation](http://nodejs.org/docs/latest/api/https.html):
+
+ - `pfx`                : Certificate, Private key and CA certificates to use for SSL.
+ - `key`                : Private key to use for SSL.
+ - `passphrase`         : A string of passphrase for the private key or pfx.
+ - `cert`               : Public x509 certificate to use.
+ - `ca`                 : An authority certificate or array of authority certificates to check the remote host against.
+ - `ciphers`            : A string describing the ciphers to use or exclude.
+ - `rejectUnauthorized` : If true, the server certificate is verified against the list of supplied CAs. An 'error' event is emitted if verification fails. Verification happens at the connection level, before the HTTP request is sent.
+ - `secureProtocol`     : The SSL method to use, e.g. SSLv3_method to force SSL version 3.
+ - `family`             : IP address family to use when resolving host and hostname. Valid values are 4 or 6. When unspecified, both IP v4 and v6 will be used.
+
+Redirect options
+----------------
+
+These options only apply if the `follow_max` (or `follow`) option is higher than 0.
+
+ - `follow_set_cookies`      : Sends the cookies received in the `set-cookie` header as part of the following request. `false` by default.
+ - `follow_set_referer`      : Sets the 'Referer' header to the requested URI when following a redirect. `false` by default.
+ - `follow_keep_method`      : If enabled, resends the request using the original verb instead of being rewritten to `get` with no data. `false` by default.
+ - `follow_if_same_host`     : When true, Needle will only follow redirects that point to the same host as the original request. `false` by default.
+ - `follow_if_same_protocol` : When true, Needle will only follow redirects that point to the same protocol as the original request. `false` by default.
+ - `follow_if_same_location` : Unless true, Needle will not follow redirects that point to same location (as set in the response header) as the original request URL. `false` by default.
+
+Overriding Defaults
+-------------------
+
+Yes sir, we have it. Needle includes a `defaults()` method, that lets you override some of the defaults for all future requests. Like this:
+
+```js
+needle.defaults({
+  open_timeout: 60000,
+  user_agent: 'MyApp/1.2.3',
+  parse_response: false });
+```
+
+This will override Needle's default user agent and 10-second timeout, and disable response parsing, so you don't need to pass those options in every other request.
+
+More advanced Proxy support
+---------------------------
+
+Since you can pass a custom HTTPAgent to Needle you can do all sorts of neat stuff. For example, if you want to use the [`tunnel`](https://github.com/koichik/node-tunnel) module for HTTPS proxying, you can do this:
+
+```js
+var tunnel = require('tunnel');
+var myAgent = tunnel.httpOverHttp({
+  proxy: { host: 'localhost' }
+});
+
+needle.get('foobar.com', { agent: myAgent });
+```
+
+Otherwise, you can use the [`hpagent`](https://github.com/delvedor/hpagent) package, which keeps the internal sockets alive to be reused.
+
+```js
+const { HttpsProxyAgent } = require('hpagent');
+needle('get', 'https://localhost:9200', {
+  agent: new HttpsProxyAgent({
+    keepAlive: true,
+    keepAliveMsecs: 1000,
+    maxSockets: 256,
+    maxFreeSockets: 256,
+    scheduling: 'lifo',
+    proxy: 'https://localhost:8080'
+  })
+});
+```
+
+Regarding the 'Connection' header
+---------------------------------
+
+Unless you're running an old version of Node (< 0.11.4), by default Needle won't set the Connection header on requests, yielding Node's default behaviour of keeping the connection alive with the target server. This speeds up immensely the process of sending several requests to the same host.
+
+On older versions, however, this has the unwanted behaviour of preventing the runtime from exiting, either because of a bug or 'feature' that was changed on 0.11.4. To overcome this Needle does set the 'Connection' header to 'close' on those versions, however this also means that making new requests to the same host doesn't benefit from Keep-Alive.
+
+So if you're stuck on 0.10 or even lower and want full speed, you can simply set the Connection header to 'Keep-Alive' by using `{ connection: 'Keep-Alive' }`. Please note, though, that an event loop handler will prevent the runtime from exiting so you'll need to manually call `process.exit()` or the universe will collapse.
+
+Examples Galore
+---------------
+
+### HTTPS GET with Basic Auth
+
+```js
+needle.get('https://api.server.com', { username: 'you', password: 'secret' },
+  function(err, resp) {
+    // used HTTP auth
+});
+```
+
+Or use [RFC-1738](http://tools.ietf.org/html/rfc1738#section-3.1) basic auth URL syntax:
+
+```js
+needle.get('https://username:password@api.server.com', function(err, resp) {
+    // used HTTP auth from URL
+});
+```
+
+### Digest Auth
+
+```js
+needle.get('other.server.com', { username: 'you', password: 'secret', auth: 'digest' },
+  function(err, resp, body) {
+    // needle prepends 'http://' to your URL, if missing
+});
+```
+
+### Custom Accept header, deflate
+
+```js
+var options = {
+  compressed : true,
+  follow     : 10,
+  accept     : 'application/vnd.github.full+json'
+}
+
+needle.get('api.github.com/users/tomas', options, function(err, resp, body) {
+  // body will contain a JSON.parse(d) object

+});
+```
+
+### GET XML object

+```js
+needle.get('https://news.ycombinator.com/rss', function(err, resp, body) {
+  // you'll get a nice object containing the nodes in the RSS
+});
+```
+
+### GET binary, output to file
+
+```js
+needle.get('http://upload.server.com/tux.png', { output: '/tmp/tux.png' }, function(err, resp, body) {
+  // you can dump any response to a file, not only binaries.
+});
+```
+
+### GET through proxy
+
+```js
+needle.get('http://search.npmjs.org', { proxy: 'http://localhost:1234' }, function(err, resp, body) {
+  // request passed through proxy
+});
+```
+
+### GET a very large document in a stream (from 0.7+)
+
+```js
+var stream = needle.get('http://www.as35662.net/100.log');
+
+stream.on('readable', function() {
+  var chunk;
+  while (chunk = this.read()) {
+    console.log('got data: ', chunk);
+  }
+});
+```
+
+### GET JSON object in a stream (from 0.7+)
+
+```js
+var stream = needle.get('http://jsonplaceholder.typicode.com/db', { parse: true });
+
+stream.on('readable', function() {
+  var node;
+
+  // our stream will only emit a single JSON root node.
+  while (node = this.read()) {
+    console.log('got data: ', node);
+  }
+});
+```
+
+### GET JSONStream flexible parser with search query (from 0.7+)
+
+```js
+
+ // The 'data' element of this stream will be the string representation
+ // of the titles of all posts.
+
+needle.get('http://jsonplaceholder.typicode.com/db', { parse: true })
+      .pipe(new JSONStream.parse('posts.*.title'));
+      .on('data', function (obj) {
+        console.log('got post title: %s', obj);
+      });
+```
+
+### File upload using multipart, passing file path
+
+```js
+var data = {
+  foo: 'bar',
+  image: { file: '/home/tomas/linux.png', content_type: 'image/png' }
+}
+
+needle.post('http://my.other.app.com', data, { multipart: true }, function(err, resp, body) {
+  // needle will read the file and include it in the form-data as binary
+});
+```
+
+### Stream upload, PUT or POST
+
+``` js
+needle.put('https://api.app.com/v2', fs.createReadStream('myfile.txt'), function(err, resp, body) {
+  // stream content is uploaded verbatim
+});
+```
+
+### Multipart POST, passing data buffer
+
+```js
+var buffer = fs.readFileSync('/path/to/package.zip');
+
+var data = {
+  zip_file: {
+    buffer       : buffer,
+    filename     : 'mypackage.zip',
+    content_type : 'application/octet-stream'
+  }
+}
+
+needle.post('http://somewhere.com/over/the/rainbow', data, { multipart: true }, function(err, resp, body) {
+  // if you see, when using buffers we need to pass the filename for the multipart body.
+  // you can also pass a filename when using the file path method, in case you want to override
+  // the default filename to be received on the other end.
+});
+```
+
+### Multipart with custom Content-Type
+
+```js
+var data = {
+  token: 'verysecret',
+  payload: {
+    value: JSON.stringify({ title: 'test', version: 1 }),
+    content_type: 'application/json'
+  }
+}
+
+needle.post('http://test.com/', data, { timeout: 5000, multipart: true }, function(err, resp, body) {
+  // in this case, if the request takes more than 5 seconds
+  // the callback will return a [Socket closed] error
+});
+```
+
+For even more examples, check out the examples directory in the repo.
+
+### Testing
+
+To run tests, you need to generate a self-signed SSL certificate in the `test` directory. After cloning the repository, run the following commands:
+
+    $ mkdir -p test/keys
+    $ openssl genrsa -out test/keys/ssl.key 2048
+    $ openssl req -new -key test/keys/ssl.key -x509 -days 999 -out test/keys/ssl.cert
+
+Then you should be able to run `npm test` once you have the dependencies in place.
+
+> Note: Tests currently only work on linux-based environments that have `/proc/self/fd`. They *do not* work on MacOS environments.
+> You can use Docker to run tests by creating a container and mounting the needle project directory on `/app`
+> `docker create --name Needle -v /app -w /app -v /app/node_modules -i node:argon`
