We +use GitHub pull requests for this purpose. Consult +[GitHub Help](https://help.github.com/articles/about-pull-requests/) for more +information on using pull requests. + +## Code Style + +- Coding style is fully defined in [`.eslintrc`](https://github.com/puppeteer/puppeteer/blob/main/.eslintrc.js) and we automatically format our code with [Prettier](https://prettier.io). +- It's recommended to set-up Prettier into your editor, or you can run `npm run eslint-fix` to automatically format any files. +- If you're working in a JS file, code should be annotated with [closure annotations](https://github.com/google/closure-compiler/wiki/Annotating-JavaScript-for-the-Closure-Compiler). +- If you're working in a TS file, you should explicitly type all variables and return types. You'll get ESLint warnings if you don't so if you're not sure use them as guidelines, and feel free to ask us for help! + +To run ESLint, use: + +```bash +npm run eslint +``` + +You can check your code (both JS & TS) type-checks by running: + +```bash +npm run tsc +``` + +## TypeScript guidelines + +- Try to avoid the use of `any` when possible. Consider `unknown` as a better alternative. You are able to use `any` if needbe, but it will generate an ESLint warning. + +## Project structure and TypeScript compilation + +The code in Puppeteer is split primarily into two folders: + +- `src` contains all source code +- `vendor` contains all dependencies that we've vendored into the codebase. See the [`vendor/README.md`](https://github.com/puppeteer/puppeteer/blob/main/vendor/README.md) for details. + +We structure these using TypeScript's project references, which lets us treat each folder like a standalone TypeScript project. + +### Shipping CJS and ESM bundles + +Currently Puppeteer ships two bundles; a CommonJS version for Node and an ESM bundle for the browser. Therefore we maintain two `tsconfig` files for each project; `tsconfig.esm.json` and `tsconfig.cjs.json`. At build time we compile twice, once outputting to CJS and another time to output to ESM. + +We compile into the `lib` directory which is what we publish on the npm repository and it's structured like so: + +``` +lib +- cjs + - puppeteer <== the output of compiling `src/tsconfig.cjs.json` + - vendor <== the output of compiling `vendor/tsconfig.cjs.json` +- esm + - puppeteer <== the output of compiling `src/tsconfig.esm.json` + - vendor <== the output of compiling `vendor/tsconfig.esm.json` +``` + +The main entry point for the Node module Puppeteer is `cjs-entry.js`. This imports `lib/cjs/puppeteer/index.js` and exposes it to Node users. + +### tsconfig for the tests + +We also maintain `test/tsconfig.test.json`. This is **only used to compile the unit test `*.spec.ts` files**. When the tests are run, we first compile Puppeteer as normal before running the unit tests **against the compiled output**. Doing this lets the test run against the compiled code we ship to users so it gives us more confidence in our compiled output being correct. + +### Root `tsconfig.json` + +The root `tsconfig.json` exists for the API Extractor; it has to find a `tsconfig.json` in the project's root directory. It is _not_ used for anything else. + + +## API guidelines + +When authoring new API methods, consider the following: + +- Expose as little information as needed. When in doubt, don’t expose new information. +- Methods are used in favor of getters/setters. + - The only exception is namespaces, e.g. `page.keyboard` and `page.coverage` +- All string literals must be small case. This includes event names and option values. +- Avoid adding "sugar" API (API that is trivially implementable in user-space) unless they're **very** demanded. + +## Commit Messages + +Commit messages should follow [the Conventional Commits format](https://www.conventionalcommits.org/en/v1.0.0/#summary). This is enforced via `npm run lint`. + +In particular, breaking changes should clearly be noted as “BREAKING CHANGE:” in the commit message footer. Example: + +``` +fix(page): fix page.pizza method + +This patch fixes page.pizza so that it works with iframes. + +Issues: #123, #234 + +BREAKING CHANGE: page.pizza now delivers pizza at home by default. +To deliver to a different location, use the "deliver" option: + `page.pizza({deliver: 'work'})`. +``` + +## Writing Documentation + +All public API should have a descriptive entry in [`docs/api.md`](https://github.com/puppeteer/puppeteer/blob/main/docs/api.md). There's a [documentation linter](https://github.com/puppeteer/puppeteer/tree/main/utils/doclint) which makes sure documentation is aligned with the codebase. + +To run the documentation linter, use: + +```bash +npm run doc +``` + +## Adding New Dependencies + +For all dependencies (both installation and development): +- **Do not add** a dependency if the desired functionality is easily implementable. +- If adding a dependency, it should be well-maintained and trustworthy. + +A barrier for introducing new installation dependencies is especially high: +- **Do not add** installation dependency unless it's critical to project success. + +There are additional considerations for dependencies that are environment agonistic. See the [`vendor/README.md`](https://github.com/puppeteer/puppeteer/blob/main/vendor/README.md) for details. + + +## Running & Writing Tests + +- Every feature should be accompanied by a test. +- Every public api event/method should be accompanied by a test. +- Tests should not depend on external services. +- Tests should work on all three platforms: Mac, Linux and Win. This is especially important for screenshot tests. + +Puppeteer tests are located in the test directory ([`test`](https://github.com/puppeteer/puppeteer/blob/main/test/) and are written using Mocha. See [`test/README.md`](https://github.com/puppeteer/puppeteer/blob/main/test/) for more details. + +Despite being named 'unit', these are integration tests, making sure public API methods and events work as expected. + +- To run all tests: + +```bash +npm run unit +``` + +- To run a specific test, substitute the `it` with `it.only`: + +```js + ... + it.only('should work', async function({server, page}) { + const response = await page.goto(server.EMPTY_PAGE); + expect(response.ok).toBe(true); + }); +``` + +- To disable a specific test, substitute the `it` with `xit` (mnemonic rule: '*cross it*'): + +```js + ... + // Using "xit" to skip specific test + xit('should work', async function({server, page}) { + const response = await page.goto(server.EMPTY_PAGE); + expect(response.ok).toBe(true); + }); +``` + +- To run tests in non-headless mode: + +```bash +HEADLESS=false npm run unit +``` + +- To run Firefox tests, firstly ensure you have Firefox installed locally (you only need to do this once, not on every test run) and then you can run the tests: + +```bash +PUPPETEER_PRODUCT=firefox node install.js +PUPPETEER_PRODUCT=firefox npm run unit +``` + +- To run tests with custom browser executable: + +```bash +BINARY=<path-to-executable> npm run unit +``` + +## Public API Coverage + +Every public API method or event should be called at least once in tests. To ensure this, there's a `coverage` command which tracks calls to public API and reports back if some methods/events were not called. + +Run coverage: + +```bash +npm run coverage +``` + +## Debugging Puppeteer + +See [Debugging Tips](README.md#debugging-tips) in the readme. + +# For Project Maintainers + +## Rolling new Chromium version + +The following steps are needed to update the Chromium version. + +1. Find a suitable Chromium revision + Not all revisions have builds for all platforms, so we need to find one that does. + To do so, run `utils/check_availability.js -rb` to find the latest suitable beta Chromium revision (see `utils/check_availability.js -help` for more options). +1. Update `src/revisions.ts` with the found revision number. +1. Run `npm run ensure-correct-devtools-protocol-revision`. + If it fails, update `package.json` with the expected `devtools-protocol` version. +1. Run `npm run tsc` and `npm install` and ensure that all tests pass. If a test fails, [bisect](#bisecting-upstream-changes) the upstream cause of the failure, and either update the test expectations accordingly (if it was an intended change) or work around the changes in Puppeteer (if it’s not desirable to change Puppeteer’s observable behavior). +1. Update `versions.js` with the new Chromium-to-Puppeteer version mapping. +1. Commit and push your changes and open a pull request. + +### Bisecting upstream changes + +Sometimes, performing a Chromium roll causes tests to fail. To figure out the cause, you need to bisect Chromium revisions to figure out the earliest possible revision that changed the behavior. The script in `utils/bisect.js` can be helpful here. Given a Node.js script that calls `process.exit(1)` for bad revisions, run this from the Puppeteer repository’s root directory: + +```sh +node utils/bisect.js --good 686378 --bad 706915 script.js +``` + +## Releasing to npm + +Releasing to npm consists of the following phases: + +1. Source Code: mark a release. + 1. Run `npm run release` to bump the version number in `package.json` and populate the changelog. + 1. Run `npm run doc` to update the docs accordingly. + 1.

Puppeteer runs [headless](https://developers.google.com/web/updates/2017/04/headless-chrome) by default, but can be configured to run full (non-headless) Chrome or Chromium. + +<!-- [START usecases] --> +###### What can I do? + +Most things that you can do manually in the browser can be done using Puppeteer! Here are a few examples to get you started: + +* Generate screenshots and PDFs of pages. +* Crawl a SPA (Single-Page Application) and generate pre-rendered content (i.e. "SSR" (Server-Side Rendering)). +* Automate form submission, UI testing, keyboard input, etc. +* Create an up-to-date, automated testing environment.

To skip the download, or to download a different browser, see [Environment variables](https://github.com/puppeteer/puppeteer/blob/v5.5.0/docs/api.md#environment-variables). + + +### puppeteer-core + +Since version 1.7.0 we publish the [`puppeteer-core`](https://www.npmjs.com/package/puppeteer-core) package, +a version of Puppeteer that doesn't download any browser by default. + +```bash +npm i puppeteer-core +# or "yarn add puppeteer-core" +``` + +`puppeteer-core` is intended to be a lightweight version of Puppeteer for launching an existing browser installation or for connecting to a remote one. Be sure that the version of puppeteer-core you install is compatible with the +browser you intend to connect to. + +See [puppeteer vs puppeteer-core](https://github.com/puppeteer/puppeteer/blob/main/docs/api.md#puppeteer-vs-puppeteer-core). + +### Usage + +Puppeteer follows the latest [maintenance LTS](https://github.com/nodejs/Release#release-schedule) version of Node. + +Note: Prior to v1.18.1, Puppeteer required at least Node v6.4.0. Versions from v1.18.1 to v2.1.0 rely on +Node 8.9.0+. Starting from v3.0.0 Puppeteer starts to rely on Node 10.18.1+. All examples below use async/await which is only supported in Node v7.6.0 or greater. + +Puppeteer will be familiar to people using other browser testing frameworks. You create an instance +of `Browser`, open pages, and then manipulate them with [Puppeteer's API](https://github.com/puppeteer/puppeteer/blob/v5.5.0/docs/api.md#). + +**Example** - navigating to https://example.com and saving a screenshot as *example.png*: + +Save file as **example.js** + +```js +const puppeteer = require('puppeteer'); + +(async () => { + const browser = await puppeteer.launch(); + const page = await browser.newPage(); + await page.goto('https://example.com'); + await page.screenshot({path: 'example.png'}); + + await browser.close(); +})(); +``` + +Execute script on the command line + +```bash +node example.js +``` + +Puppeteer sets an initial page size to 800×600px, which defines the screenshot size. The page size can be customized with [`Page.setViewport()`](https://github.com/puppeteer/puppeteer/blob/v5.5.0/docs/api.md#pagesetviewportviewport). + +**Example** - create a PDF. + +Save file as **hn.js** + +```js +const puppeteer = require('puppeteer'); + +(async () => { + const browser = await puppeteer.launch(); + const page = await browser.newPage(); + await page.goto('https://news.ycombinator.com', {waitUntil: 'networkidle2'}); + await page.pdf({path: 'hn.pdf', format: 'A4'}); + + await browser.close(); +})(); +``` + +Execute script on the command line + +```bash +node hn.js +``` + +See [`Page.pdf()`](https://github.com/puppeteer/puppeteer/blob/v5.5.0/docs/api.md#pagepdfoptions) for more information about creating pdfs. + +**Example** - evaluate script in the context of the page + +Save file as **get-dimensions.js** + +```js +const puppeteer = require('puppeteer'); + +(async () => { + const browser = await puppeteer.launch(); + const page = await browser.newPage(); + await page.goto('https://example.com'); + + // Get the "viewport" of the page, as reported by the page. + const dimensions = await page.evaluate(() => { + return { + width: document.documentElement.clientWidth, + height: document.documentElement.clientHeight, + deviceScaleFactor: window.devicePixelRatio + }; + }); + + console.log('Dimensions:', dimensions); + + await browser.close(); +})(); +``` + +Execute script on the command line + +```bash +node get-dimensions.js +``` + +See [`Page.evaluate()`](https://github.com/puppeteer/puppeteer/blob/v5.5.0/docs/api.md#pageevaluatepagefunction-args) for more information on `evaluate` and related methods like `evaluateOnNewDocument` and `exposeFunction`. + +<!-- [END getstarted] --> + +<!-- [START runtimesettings] --> +## Default runtime settings + +**1. Uses Headless mode** + +Puppeteer launches Chromium in [headless mode](https://developers.google.com/web/updates/2017/04/headless-chrome). To launch a full version of Chromium, set the [`headless` option](https://github.com/puppeteer/puppeteer/blob/v5.5.0/docs/api.md#puppeteerlaunchoptions) when launching a browser: + +```js +const browser = await puppeteer.launch({headless: false}); // default is true +``` + +**2. Runs a bundled version of Chromium** + +By default, Puppeteer downloads and uses a specific version of Chromium so its API +is guaranteed to work out of the box. To use Puppeteer with a different version of Chrome or Chromium, +pass in the executable's path when creating a `Browser` instance: + +```js +const browser = await puppeteer.launch({executablePath: '/path/to/Chrome'}); +``` + +You can also use Puppeteer with Firefox Nightly (experimental support). See [`Puppeteer.launch()`](https://github.com/puppeteer/puppeteer/blob/v5.5.0/docs/api.md#puppeteerlaunchoptions) for more information. + +See [`this article`](https://www.howtogeek.com/202825/what%E2%80%99s-the-difference-between-chromium-and-chrome/) for a description of the differences between Chromium and Chrome. [`This article`](https://chromium.googlesource.com/chromium/src/+/master/docs/chromium_browser_vs_google_chrome.md) describes some differences for Linux users. + +**3.

Turn off headless mode - sometimes it's useful to see what the browser is + displaying. Instead of launching in headless mode, launch a full version of + the browser using `headless: false`: + + ```js + const browser = await puppeteer.launch({headless: false}); + ``` + +2. Slow it down - the `slowMo` option slows down Puppeteer operations by the + specified amount of milliseconds. It's another way to help see what's going on. + + ```js + const browser = await puppeteer.launch({ + headless: false, + slowMo: 250 // slow down by 250ms + }); + ``` + +3. Capture console output - You can listen for the `console` event. + This is also handy when debugging code in `page.evaluate()`: + + ```js + page.on('console', msg => console.log('PAGE LOG:', msg.text())); + + await page.evaluate(() => console.log(`url is ${location.href}`)); + ``` + +4. Use debugger in application code browser + + There are two execution context: node.js that is running test code, and the browser + running application code being tested. This lets you debug code in the + application code browser; ie code inside `evaluate()`. + + - Use `{devtools: true}` when launching Puppeteer: + + ```js + const browser = await puppeteer.launch({devtools: true}); + ``` + + - Change default test timeout: + + jest: `jest.setTimeout(100000);` + + jasmine: `jasmine.DEFAULT_TIMEOUT_INTERVAL = 100000;` + + mocha: `this.timeout(100000);` (don't forget to change test to use [function and not '=>'](https://stackoverflow.com/a/23492442)) + + - Add an evaluate statement with `debugger` inside / add `debugger` to an existing evaluate statement: + + ```js + await page.evaluate(() => {debugger;}); + ``` + + The test will now stop executing in the above evaluate statement, and chromium will stop in debug mode. + +5. Use debugger in node.js + + This will let you debug test code. For example, you can step over `await page.click()` in the node.js script and see the click happen in the application code browser. + + Note that you won't be able to run `await page.click()` in + DevTools console due to this [Chromium bug](https://bugs.chromium.org/p/chromium/issues/detail?id=833928). So if + you want to try something out, you have to add it to your test file. + + - Add `debugger;` to your test, eg: + + ```js + debugger; + await page.click('a[target=_blank]'); + ``` + + - Set `headless` to `false` + - Run `node --inspect-brk`, eg `node --inspect-brk node_modules/.bin/jest tests` + - In Chrome open `chrome://inspect/#devices` and click `inspect` + - In the newly opened test browser, type `F8` to resume test execution + - Now your `debugger` will be hit and you can debug in the test browser + + +6. Enable verbose logging - internal DevTools protocol traffic + will be logged via the [`debug`](https://github.com/visionmedia/debug) module under the `puppeteer` namespace. + + # Basic verbose logging + env DEBUG="puppeteer:*" node script.js + + # Protocol traffic can be rather noisy. This example filters out all Network domain messages + env DEBUG="puppeteer:*" env DEBUG_COLORS=true node script.js 2>&1 | grep -v '"Network' + +7. Debug your Puppeteer (node) code easily, using [ndb](https://github.com/GoogleChromeLabs/ndb) + + - `npm install -g ndb` (or even better, use [npx](https://github.com/zkat/npx)!) + + - add a `debugger` to your Puppeteer (node) code + + - add `ndb` (or `npx ndb`) before your test command. For example: + + `ndb jest` or `ndb mocha` (or `npx ndb jest` / `npx ndb mocha`) + + - debug your test inside chromium like a boss! + +<!-- [END debugging] --> + + +<!-- [START typescript] --> +## Usage with TypeScript + +We have recently completed a migration to move the Puppeteer source code from JavaScript to TypeScript and we're currently working on shipping type definitions for TypeScript with Puppeteer's npm package. + +Until this work is complete we recommend installing the Puppeteer type definitions from the [DefinitelyTyped](https://definitelytyped.org/) repository: + +```bash +npm install --save-dev @types/puppeteer +``` + +The types that you'll see appearing in the Puppeteer source code are based off the great work of those who have contributed to the `@types/puppeteer` package. We really appreciate the hard work those people put in to providing high quality TypeScript definitions for Puppeteer's users. + +<!-- [END typescript] --> + + +## Contributing to Puppeteer + +Check out [contributing guide](https://github.com/puppeteer/puppeteer/blob/main/CONTRIBUTING.md) to get an overview of Puppeteer development. + +<!-- [START faq] --> + +# FAQ + +#### Q: Who maintains Puppeteer? + +The Chrome DevTools team maintains the library, but we'd love your help and expertise on the project! +See [Contributing](https://github.com/puppeteer/puppeteer/blob/main/CONTRIBUTING.md). + +#### Q: What is the status of cross-browser support? + +Official Firefox support is currently experimental. The ongoing collaboration with Mozilla aims to support common end-to-end testing use cases, for which developers expect cross-browser coverage. The Puppeteer team needs input from users to stabilize Firefox support and to bring missing APIs to our attention. + +From Puppeteer v2.1.0 onwards you can specify [`puppeteer.launch({product: 'firefox'})`](https://github.com/puppeteer/puppeteer/blob/v5.5.0/docs/api.md#puppeteerlaunchoptions) to run your Puppeteer scripts in Firefox Nightly, without any additional custom patches. While [an older experiment](https://www.npmjs.com/package/puppeteer-firefox) required a patched version of Firefox, [the current approach](https://wiki.mozilla.org/Remote) works with “stock” Firefox. + +We will continue to collaborate with other browser vendors to bring Puppeteer support to browsers such as Safari. +This effort includes exploration of a standard for executing cross-browser commands (instead of relying on the non-standard DevTools Protocol used by Chrome). + +#### Q: What are Puppeteer’s goals and principles? + +The goals of the project are: + +- Provide a slim, canonical library that highlights the capabilities of the [DevTools Protocol](https://chromedevtools.github.io/devtools-protocol/). +- Provide a reference implementation for similar testing libraries. Eventually, these other frameworks could adopt Puppeteer as their foundational layer. +- Grow the adoption of headless/automated browser testing. +- Help dogfood new DevTools Protocol features...and catch bugs! +- Learn more about the pain points of automated browser testing and help fill those gaps. + +We adapt [Chromium principles](https://www.chromium.org/developers/core-principles) to help us drive product decisions: +- **Speed**: Puppeteer has almost zero performance overhead over an automated page. +- **Security**: Puppeteer operates off-process with respect to Chromium, making it safe to automate potentially malicious pages. +- **Stability**: Puppeteer should not be flaky and should not leak memory. +- **Simplicity**: Puppeteer provides a high-level API that’s easy to use, understand, and debug. + +#### Q: Is Puppeteer replacing Selenium/WebDriver? + +**No**. Both projects are valuable for very different reasons: +- Selenium/WebDriver focuses on cross-browser automation; its value proposition is a single standard API that works across all major browsers. +- Puppeteer focuses on Chromium; its value proposition is richer functionality and higher reliability. + +That said, you **can** use Puppeteer to run tests against Chromium, e.g. using the community-driven [jest-puppeteer](https://github.com/smooth-code/jest-puppeteer). While this probably shouldn’t be your only testing solution, it does have a few good points compared to WebDriver: + +- Puppeteer requires zero setup and comes bundled with the Chromium version it works best with, making it [very easy to start with](https://github.com/puppeteer/puppeteer/#getting-started). At the end of the day, it’s better to have a few tests running chromium-only, than no tests at all. +- Puppeteer has event-driven architecture, which removes a lot of potential flakiness. There’s no need for evil “sleep(1000)” calls in puppeteer scripts. +- Puppeteer runs headless by default, which makes it fast to run. Puppeteer v1.5.0 also exposes browser contexts, making it possible to efficiently parallelize test execution. +- Puppeteer shines when it comes to debugging: flip the “headless” bit to false, add “slowMo”, and you’ll see what the browser is doing. You can even open Chrome DevTools to inspect the test environment. + +#### Q: Why doesn’t Puppeteer v.XXX work with Chromium v.YYY? + +We see Puppeteer as an **indivisible entity** with Chromium. Each version of Puppeteer bundles a specific version of Chromium – **the only** version it is guaranteed to work with. + +This is not an artificial constraint: A lot of work on Puppeteer is actually taking place in the Chromium repository. Here’s a typical story: +- A Puppeteer bug is reported: https://github.com/puppeteer/puppeteer/issues/2709 +- It turned out this is an issue with the DevTools protocol, so we’re fixing it in Chromium: https://chromium-review.googlesource.com/c/chromium/src/+/1102154 +- Once the upstream fix is landed, we roll updated Chromium into Puppeteer: https://github.com/puppeteer/puppeteer/pull/2769 + +However, oftentimes it is desirable to use Puppeteer with the official Google Chrome rather than Chromium. For this to work, you should install a `puppeteer-core` version that corresponds to the Chrome version. + +For example, in order to drive Chrome 71 with puppeteer-core, use `chrome-71` npm tag: +```bash +npm install puppeteer-core@chrome-71 +``` + +#### Q: Which Chromium version does Puppeteer use? + +Look for the `chromium` entry in [revisions.ts](https://github.com/puppeteer/puppeteer/blob/main/src/revisions.ts). To find the corresponding Chromium commit and version number, search for the revision prefixed by an `r` in [OmahaProxy](https://omahaproxy.appspot.com/)'s "Find Releases" section. + + +#### Q: Which Firefox version does Puppeteer use? + +Since Firefox support is experimental, Puppeteer downloads the latest [Firefox Nightly](https://wiki.mozilla.org/Nightly) when the `PUPPETEER_PRODUCT` environment variable is set to `firefox`. That's also why the value of `firefox` in [revisions.ts](https://github.com/puppeteer/puppeteer/blob/main/src/revisions.ts) is `latest` -- Puppeteer isn't tied to a particular Firefox version. + +To fetch Firefox Nightly as part of Puppeteer installation: + +```bash +PUPPETEER_PRODUCT=firefox npm i puppeteer +# or "yarn add puppeteer" +``` + +#### Q: What’s considered a “Navigation”? + +From Puppeteer’s standpoint, **“navigation” is anything that changes a page’s URL**. +Aside from regular navigation where the browser hits the network to fetch a new document from the web server, this includes [anchor navigations](https://www.w3.org/TR/html5/single-page.html#scroll-to-fragid) and [History API](https://developer.mozilla.org/en-US/docs/Web/API/History_API) usage. + +With this definition of “navigation,” **Puppeteer works seamlessly with single-page applications.** + +#### Q: What’s the difference between a “trusted" and "untrusted" input event? + +In browsers, input events could be divided into two big groups: trusted vs. untrusted. + +- **Trusted events**: events generated by users interacting with the page, e.g. using a mouse or keyboard. +- **Untrusted event**: events generated by Web APIs, e.g. `document.createEvent` or `element.click()` methods. + +Websites can distinguish between these two groups: +- using an [`Event.isTrusted`](https://developer.mozilla.org/en-US/docs/Web/API/Event/isTrusted) event flag +- sniffing for accompanying events. For example, every trusted `'click'` event is preceded by `'mousedown'` and `'mouseup'` events. + +For automation purposes it’s important to generate trusted events. **All input events generated with Puppeteer are trusted and fire proper accompanying events.** If, for some reason, one needs an untrusted event, it’s always possible to hop into a page context with `page.evaluate` and generate a fake event: + +```js +await page.evaluate(() => { + document.querySelector('button[type=submit]').click(); +}); +``` + +#### Q: What features does Puppeteer not support? + +You may find that Puppeteer does not behave as expected when controlling pages that incorporate audio and video. (For example, [video playback/screenshots is likely to fail](https://github.com/puppeteer/puppeteer/issues/291).) There are two reasons for this: + +* Puppeteer is bundled with Chromium — not Chrome — and so by default, it inherits all of [Chromium's media-related limitations](https://www.chromium.org/audio-video). This means that Puppeteer does not support licensed formats such as AAC or H.264. (However, it is possible to force Puppeteer to use a separately-installed version Chrome instead of Chromium via the [`executablePath` option to `puppeteer.launch`](https://github.com/puppeteer/puppeteer/blob/v5.5.0/docs/api.md#puppeteerlaunchoptions). You should only use this configuration if you need an official release of Chrome that supports these media formats.) +* Since Puppeteer (in all configurations) controls a desktop version of Chromium/Chrome, features that are only supported by the mobile version of Chrome are not supported. This means that Puppeteer [does not support HTTP Live Streaming (HLS)](https://caniuse.com/#feat=http-live-streaming). + +#### Q: I am having trouble installing / running Puppeteer in my test environment. Where should I look for help? +We have a [troubleshooting](https://github.com/puppeteer/puppeteer/blob/main/docs/troubleshooting.md) guide for various operating systems that lists the required dependencies. + +#### Q: How do I try/test a prerelease version of Puppeteer? + +You can check out this repo or install the latest prerelease from npm: + +```bash +npm i --save puppeteer@next +``` + +Please note that prerelease may be unstable and contain bugs. + +#### Q: I have more questions!

If the dep ships as compiled JS, you may need to disable TypeScript checking the file. Add an entry to the `excludes` property of the TSConfig files in `vendor`.
