+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+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:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">

+
+#### 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);
+```
+
+In Chromium-based web browsers (e.g. Brave, Chrome, and Electron), the JavaScript console will—by default—only show messages logged by `debug` if the "Verbose" log level is _enabled_.
+
+<img width="647" src="https://user-images.githubusercontent.com/7143133/152083257-29034707-c42c-4959-8add-3cee850e6fcf.png">
+
+## 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
+```
+
+`disable()`
+
+Will disable all namespaces. The functions returns the namespaces currently
+enabled (and skipped). This can be useful if you want to disable debugging
+temporarily without knowing what was enabled to begin with.
+
+For example:
+
+```js
+let debug = require('debug');
+debug.enable('foo:*,-foo:bar');
+let namespaces = debug.disable();
+debug.enable(namespaces);
+```
+
+Note: There is no guarantee that the string will be identical to the initial
+enable string, but semantically they will be identical.
+
+## 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.
+
+## Usage in child processes
+
+Due to the way `debug` detects if the output is a TTY or not, colors are not shown in child processes when `stderr` is piped. A solution is to pass the `DEBUG_COLORS=1` environment variable to the child process.  
+For example:
+
+```javascript
+worker = fork(WORKER_WRAP_PATH, [workerPath], {
+  stdio: [
+    /* stdin: */ 0,
+    /* stdout: */ 'pipe',
+    /* stderr: */ 'pipe',
+    'ipc',
+  ],
+  env: Object.assign({}, process.env, {
+    DEBUG_COLORS: 1 // without this settings, colors won't be shown
+  }),
+});
+
+worker.stderr.pipe(process.stderr, { end: false });
+```

+# ms
+
+![CI](https://github.com/vercel/ms/workflows/CI/badge.svg)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days')  // 172800000
+ms('1d')      // 86400000
+ms('10h')     // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h')      // 7200000
+ms('1m')      // 60000
+ms('5s')      // 5000
+ms('1y')      // 31557600000
+ms('100')     // 100
+ms('-3 days') // -259200000
+ms('-1h')     // -3600000
+ms('-200')    // -200
+```
+
+### Convert from Milliseconds
+
+```js
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(-3 * 60000)        // "-3m"
+ms(ms('10 hours'))    // "10h"
+```
+
+### Time Format Written-Out
+
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(-3 * 60000, { long: true })        // "-3 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
+```
+
+## Features
+
+- Works both in [Node.js](https://nodejs.org) and in the browser
+- If a number is supplied to `ms`, a string with a unit is returned
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
+- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
+
+## Related Packages
+
+- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
+
+## Caught a Bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+
+- `opts` **PluginOptions?**
+
+Base class for `puppeteer-extra` plugins.
+
+Provides convenience methods to avoid boilerplate.
+
+All common `puppeteer` browser events will be bound to
+the plugin instance, if a respectively named class member is found.
+
+Please refer to the [puppeteer API documentation](https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md) as well.
+
+Example:
+
+```javascript
+// hello-world-plugin.js
+const { PuppeteerExtraPlugin } = require('puppeteer-extra-plugin')
+
+class Plugin extends PuppeteerExtraPlugin {
+  constructor(opts = {}) {
+    super(opts)
+  }
+
+  get name() {
+    return 'hello-world'
+  }
+
+  async onPageCreated(page) {
+    this.debug('page created', page.url())
+    const ua = await page.browser().userAgent()
+    this.debug('user agent', ua)
+  }
+}
+
+module.exports = function(pluginConfig) {
+  return new Plugin(pluginConfig)
+}
+
+// foo.js
+const puppeteer = require('puppeteer-extra')
+puppeteer.use(require('./hello-world-plugin')())
+;(async () => {
+  const browser = await puppeteer.launch({ headless: false })
+  const page = await browser.newPage()
+  await page.goto('http://example.com', { waitUntil: 'domcontentloaded' })
+  await browser.close()
+})()
+```

+
+Type: **[string](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)**
+
+Plugin name (required).
+
+Convention:
+
+- Package: `puppeteer-extra-plugin-anonymize-ua`
+- Name: `anonymize-ua`
+
+Example:
+
+```javascript
+get name () { return 'anonymize-ua' }

+
+Type: **PluginOptions**
+
+Plugin defaults (optional).
+
+If defined will be ([deep-](https://github.com/jonschlinkert/merge-deep))merged with the (optional) user supplied options (supplied during plugin instantiation).
+
+The result of merging defaults with user supplied options can be accessed through `this.opts`.
+
+Example:
+
+```javascript
+get defaults () {
+  return {
+    stripHeadless: true,
+    makeWindows: true,
+    customFn: null
+  }
+}
+
+// Users can overwrite plugin defaults during instantiation:
+puppeteer.use(require('puppeteer-extra-plugin-foobar')({ makeWindows: false }))
+```
+
+- **See: \[[opts]]**
+

+
+#### .[requirements](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L145-L147)
+
+Type: **PluginRequirements**
+
+Plugin requirements (optional).
+
+Signal certain plugin requirements to the base class and the user.
+
+Currently supported:
+
+- `launch`
+  - If the plugin only supports locally created browser instances (no `puppeteer.connect()`),
+    will output a warning to the user.
+- `headful`
+  - If the plugin doesn't work in `headless: true` mode,
+    will output a warning to the user.
+- `dataFromPlugins`
+  - In case the plugin requires data from other plugins.
+    will enable usage of `this.getDataFromPlugins()`.
+- `runLast`
+  - In case the plugin prefers to run after the others.
+    Useful when the plugin needs data from others.
+
+Example:
+
+```javascript
+get requirements () {
+  return new Set(['runLast', 'dataFromPlugins'])
+}
+```
+
+---
+
+#### .[dependencies](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L160-L162)
+
+Type: **PluginDependencies**
+
+Plugin dependencies (optional).
+
+Missing plugins will be required() by puppeteer-extra.
+
+Example:
+
+```javascript
+get dependencies () {
+  return new Set(['user-preferences'])
+}
+// Will ensure the 'puppeteer-extra-plugin-user-preferences' plugin is loaded.
+```
+
+---
+
+#### .[data](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L196-L198)
+
+Type: **[Array](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Array)&lt;PluginData>**
+
+Plugin data (optional).
+
+Plugins can expose data (an array of objects), which in turn can be consumed by other plugins,
+that list the `dataFromPlugins` requirement (by using `this.getDataFromPlugins()`).
+
+Convention: `[ {name: 'Any name', value: 'Any value'} ]`
+
+Example:
+
+```javascript
+// plugin1.js
+get data () {
+  return [
+    {
+      name: 'userPreferences',
+      value: { foo: 'bar' }
+    },
+    {
+      name: 'userPreferences',
+      value: { hello: 'world' }
+    }
+  ]
+
+// plugin2.js
+get requirements () { return new Set(['dataFromPlugins']) }
+
+async beforeLaunch () {
+  const prefs = this.getDataFromPlugins('userPreferences').map(d => d.value)
+  this.debug(prefs) // => [ { foo: 'bar' }, { hello: 'world' } ]
+}
+```
+
+- **See: \[[getDataFromPlugins]]**
+
+---
+
+#### .[opts](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L215-L217)
+
+Type: **PluginOptions**
+
+Access the plugin options (usually the `defaults` merged with user defined options)
+
+To skip the auto-merging of defaults with user supplied opts don't define a `defaults`
+property and set the `this._opts` Object in your plugin constructor directly.
+
+Example:
+
+```javascript
+get defaults () { return { foo: "bar" } }
+
+async onPageCreated (page) {
+  this.debug(this.opts.foo) // => bar
+}
+```
+
+- **See: \[[defaults]]**
+
+---
+
+#### .[debug](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L235-L237)
+
+Type: **Debugger**
+
+Convenience debug logger based on the [debug] module.
+Will automatically namespace the logging output to the plugin package name.
+
+[debug]: https://www.npmjs.com/package/debug
+
+```bash
+# toggle output using environment variables
+DEBUG=puppeteer-extra-plugin:<plugin_name> node foo.js
+# to debug all the things:
+DEBUG=puppeteer-extra,puppeteer-extra-plugin:* node foo.js
+```
+
+Example:
+
+```javascript
+this.debug('hello world')
+// will output e.g. 'puppeteer-extra-plugin:anonymize-ua hello world'
+```
+
+---
+
+#### .[beforeLaunch(options)](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L256-L258)
+
+- `options` **any** Puppeteer launch options
+
+Before a new browser instance is created/launched.
+
+Can be used to modify the puppeteer launch options by modifying or returning them.
+
+Plugins using this method will be called in sequence to each
+be able to update the launch options.
+
+Example:
+
+```javascript
+async beforeLaunch (options) {
+  if (this.opts.flashPluginPath) {
+    options.args.push(`--ppapi-flash-path=${this.opts.flashPluginPath}`)
+  }
+}
+```
+
+---
+
+#### .[afterLaunch(browser, opts)](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L287-L292)
+
+- `browser` **Puppeteer.Browser** The `puppeteer` browser instance.
+- `opts` (optional, default `{options:({}as Puppeteer.LaunchOptions)}`)
+
+After the browser has launched.
+
+Note: Don't assume that there will only be a single browser instance during the lifecycle of a plugin.
+It's possible that `pupeeteer.launch` will be called multiple times and more than one browser created.
+In order to make the plugins as stateless as possible don't store a reference to the browser instance
+in the plugin but rather consider alternatives.
+
+E.g. when using `onPageCreated` you can get a browser reference by using `page.browser()`.
+
+Alternatively you could expose a class method that takes a browser instance as a parameter to work with:
+
+```es6
+const fancyPlugin = require('puppeteer-extra-plugin-fancy')()
+puppeteer.use(fancyPlugin)
+const browser = await puppeteer.launch()
+await fancyPlugin.killBrowser(browser)
+```
+
+Example:
+
+```javascript
+async afterLaunch (browser, opts) {
+  this.debug('browser has been launched', opts.options)
+}
+```
+
+---
+
+#### .[beforeConnect(options)](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L305-L307)
+
+- `options` **[Object](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object)** Puppeteer connect options
+
+Before connecting to an existing browser instance.
+
+Can be used to modify the puppeteer connect options by modifying or returning them.
+
+Plugins using this method will be called in sequence to each
+be able to update the launch options.
+
+---
+
+#### .[afterConnect(browser, opts)](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L319-L321)
+
+- `browser` **Puppeteer.Browser** The `puppeteer` browser instance.
+- `opts` **[Object](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object)** (optional, default `{}`)
+  - `opts.options` **[Object](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object)** Puppeteer connect options used.
+
+After connecting to an existing browser instance.
+
+> Note: Don't assume that there will only be a single browser instance during the lifecycle of a plugin.
+
+---
+
+#### .[onBrowser(browser, opts)](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L335-L337)
+
+- `browser` **Puppeteer.Browser** The `puppeteer` browser instance.
+- `opts` **any**
+
+Returns: **[Promise](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise)&lt;void>**
+
+Called when a browser instance is available.
+
+This applies to both `puppeteer.launch()` and `puppeteer.connect()`.
+
+Convenience method created for plugins that need access to a browser instance
+and don't mind if it has been created through `launch` or `connect`.
+
+> Note: Don't assume that there will only be a single browser instance during the lifecycle of a plugin.
+
+---
+
+#### .[onTargetCreated(target)](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L348-L350)
+
+- `target` **Puppeteer.Target**
+
+Called when a target is created, for example when a new page is opened by window.open or browser.newPage.
+
+> Note: This includes target creations in incognito browser contexts.
+>
+> Note: This includes browser instances created through `.launch()` as well as `.connect()`.
+
+---
+
+#### .[onPageCreated(page, target)](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L371-L373)
+
+- `page` **Puppeteer.Page**
+- `target` **Puppeteer.Target**
+
+Same as `onTargetCreated` but prefiltered to only contain Pages, for convenience.
+
+> Note: This includes page creations in incognito browser contexts.
+>
+> Note: This includes browser instances created through `.launch()` as well as `.connect()`.
+
+Example:
+
+```javascript
+async onPageCreated (page) {
+  let ua = await page.browser().userAgent()
+  if (this.opts.stripHeadless) {
+    ua = ua.replace('HeadlessChrome/', 'Chrome/')
+  }
+  this.debug('new ua', ua)
+  await page.setUserAgent(ua)
+}
+```
+
+---
+
+#### .[onTargetChanged(target)](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L384-L386)
+
+- `target` **Puppeteer.Target**
+
+Called when the url of a target changes.
+
+> Note: This includes target changes in incognito browser contexts.
+>
+> Note: This includes browser instances created through `.launch()` as well as `.connect()`.
+
+---
+
+#### .[onTargetDestroyed(target)](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L397-L399)
+
+- `target` **Puppeteer.Target**
+
+Called when a target is destroyed, for example when a page is closed.
+
+> Note: This includes target destructions in incognito browser contexts.
+>
+> Note: This includes browser instances created through `.launch()` as well as `.connect()`.
+
+---
+
+#### .[onDisconnected()](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L408-L410)
+
+Called when Puppeteer gets disconnected from the Chromium instance.
+
+This might happen because of one of the following:
+
+- Chromium is closed or crashed
+- The `browser.disconnect` method was called
+
+---
+
+#### .[onClose()](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L424-L426)
+
+**Deprecated:** Since puppeteer v1.6.0 `onDisconnected` has been improved
+and should be used instead of `onClose`.
+
+In puppeteer &lt; v1.6.0 `onDisconnected` was not catching all exit scenarios.
+In order for plugins to clean up properly (e.g. deleting temporary files)
+the `onClose` method had been introduced.
+
+> Note: Might be called multiple times on exit.
+>
+> Note: This only includes browser instances created through `.launch()`.
+
+---
+
+#### .[onPluginRegistered()](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L433-L435)
+
+After the plugin has been registered in `puppeteer-extra`.
+
+Normally right after `puppeteer.use(plugin)` is called
+

+
+#### .[getDataFromPlugins(name?)](https://github.com/berstend/puppeteer-extra/blob/dc8b90260a927c0c66c4585c5a56092ea9c35049/packages/puppeteer-extra-plugin/src/index.ts#L448-L450)
+
+- `name` **[string](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)?** Filter data by `name` property
+
+Returns: **[Array](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Array)&lt;PluginData>**
+
+Helper method to retrieve `data` objects from other plugins.
+
+A plugin needs to state the `dataFromPlugins` requirement
+in order to use this method. Will be mapped to `puppeteer.getPluginData`.
