System requirements
Playwright requires Node.js version 10.15 or above. The browser binaries for Chromium, Firefox and WebKit work across the 3 platforms (Windows, macOS, Linux):
- Windows: Works with Windows and Windows Subsystem for Linux (WSL).
- macOS: Requires 10.14 or above.
- Linux: Depending on your Linux distribution, you might need to install additional
dependencies to run the browsers.
- For Ubuntu 18.04, the additional dependencies are defined in our Docker image, which is based on Ubuntu.
Managing browser binaries
Each version of Playwright needs specific versions of browser binaries to operate. By default Playwright downloads Chromium, WebKit and Firefox browsers into the OS-specific cache folders:
%USERPROFILE%\AppData\Local\ms-playwright
on Windows~/Library/Caches/ms-playwright
on MacOS~/.cache/ms-playwright
on Linux
npm i playwright
These browsers will take few hundreds of megabytes of the disk space when installed:
du -hs ./Library/Caches/ms-playwright/*
281M chromium-XXXXXX
187M firefox-XXXX
180M webkit-XXXX
You can override default behavior using environment variables. When installing Playwright, ask it to download browsers into a specific location:
$ PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers npm i playwright
When running Playwright scripts, ask it to search for browsers in a shared location:
$ PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers node playwright-script.js
Or you can opt into the hermetic install and place binaries under the node_modules/
folder:
$ PLAYWRIGHT_BROWSERS_PATH=0 node playwright-script.js
Playwright keeps track of packages that need those browsers and will garbage collect them as you update Playwright to the newer versions.
Note
Developers can opt-in in this mode via exporting
PLAYWRIGHT_BROWSERS_PATH=$HOME/pw-browsers
in their.bashrc
.
Download from artifact repository
By default, Playwright downloads browsers from Microsoft and Google public CDNs.
Sometimes companies maintain an internal artifact repository to host browser
binaries. In this case, Playwright can be configured to download from a custom
location using the PLAYWRIGHT_DOWNLOAD_HOST
env variable.
$ PLAYWRIGHT_DOWNLOAD_HOST=192.168.1.78 npm i playwright
Skip browser downloads
In certain cases, it is desired to avoid browser downloads altogether because browser binaries are managed separately.
This can be done by setting PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD
variable before installation.
$ PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 npm i playwright
Download single browser binary
Playwright ships three packages that bundle only a single browser:
Note
All configuration environment variables also apply to these packages.
Using these packages is as easy as using a regular Playwright:
Install a specific package
$ npm i playwright-webkit
Require package
// Notice a proper package name in require
const { webkit } = require('playwright-webkit');
(async () => {
const browser = await webkit.launch();
// ....
})();
