Playwright

Installing browsers for playwright under NixOS

Normally, at first run, playwright will tell you to run playwright install. The purpose of this is to install browsers for you that it can then use for testing. The installation itself will technically work. Unfortunately, the installed browsers will not be suitable to be used inside NixOS. This is due to the fact that dependencies will not be at places where the browsers expect them to be. To mitigate this problem, nixpkgs has a package called playwright-driver.browsers. Before you start your script, make sure to set

export PLAYWRIGHT_BROWSERS_PATH=/path/to/drivers
