However, you can change that path with the PUPPETEER_DOWNLOAD_PATH environment variable. The default download path is node_modules/puppeteer/.local-chromium. Q: Chromium gets downloaded on every npm ci run.
We have a troubleshooting guide for various operating systems that lists the required dependencies. Q: I am having trouble installing / running Puppeteer in my test environment. This means that Puppeteer does not support HTTP Live Streaming (HLS).
(However, it is possible to force Puppeteer to use a separately-installed version Chrome instead of Chromium via the executablePath option to puppeteer.launch. This means that Puppeteer does not support licensed formats such as AAC or H.264. Puppeteer is bundled with Chromium - not Chrome - and so by default, it inherits all of Chromium's media-related limitations.(For example, video playback/screenshots is likely to fail.) There are two reasons for this: You may find that Puppeteer does not behave as expected when controlling pages that incorporate audio and video. The Puppeteer team needs input from users to stabilize Firefox support and to bring missing APIs to our attention.įrom Puppeteer v2.1.0 onwards you can specify puppeteer.launch( ) Q: What features does Puppeteer not support? The ongoing collaboration with Mozilla aims to support common end-to-end testing use cases, for which developers expect cross-browser coverage. Official Firefox support is currently experimental. Q: What is the status of cross-browser support? The Chrome DevTools team maintains the library, but we'd love your help and expertise on the project!
Contributing to PuppeteerĬheck out contributing guide to get an overview of Puppeteer development. We really appreciate the hard work those people put in to providing high quality TypeScript definitions for Puppeteer's users. It's just a small script that helps me build CLI utilities easily that opens the browser, navigates to a page, performs your action and then cleans up after itself.Npm install -save-dev types that you'll see appearing in the Puppeteer source code are based off the great work of those who have contributed to the package. Launch, Open tab, navigate - it's not complex, it's just more boilerplate than I want to create for simple scripts. The problem that I have with Puppeteer is the opening stanza that you need to do anything.
Instead of going to many pages, I wanted to take many screenshots of elements on the page. One demo I wanted to make was inspired by Ire's Capturing 422 live images post where she ran a puppeteer script that would navigate to many pages and take a screenshot. Specifically I love scripting the browser to scrape, manipulate and interact with pages. I love Puppeteer - it lets me play around with the ideas of The Headless Web - that is running the web in a browser without a visible browser and even build tools like DOM-curl (Curl that runs JavaScript).
