Npm ci # Q: I have more questions! Where do I ask? # a new run of npm ci will check for the existence of # by default the Chromium executable path is inferred Puppeteer uses that variable to resolve the Chromium executable location during launch, so you don’t need to specify PUPPETEER_EXECUTABLE_PATH as well.įor example, if you wish to keep the Chromium download in ~/.npm/chromium: export PUPPETEER_DOWNLOAD_PATH =~/.npm/chromium 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). 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.You should only use this configuration if you need an official release of Chrome that supports these media formats.) (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! See Contributing.
