• (v1.38) Introduce @playwright/browser-chromium, @playwright/browser-webkit, @playwright/browser-firefox.
• (v1.38) Make playwright not install browsers.
• (v1.38) Create migration writeup for playwright package.
• (v1.38) Move code from playwright-test to playwright, make @playwright/test reexport everything from playwright - chore: make @playwright/test depend on playwright #26946

Breaking: Playwright no longer downloads browsers automatically

Note

If you are using @playwright/test package, this change does not affect you.

Playwright recommends to use @playwright/test package and download browsers via npx playwright install command. If you are following this recommendation, nothing has changed for you.

However, up to v1.38, installing the playwright package instead of @playwright/test did automatically download browsers. This is no longer the case, and we recommend to explicitly download browsers via npx playwright install command.

v1.37 and earlier

playwright package was downloading browsers during npm install, while @playwright/test was not.

v1.38 and later

playwright and @playwright/test packages do not download browsers during npm install.

Recommended migration

Run npx playwright install to download browsers after npm install. For example, in your CI configuration:

- run: npm ci
- run: npx playwright install --with-deps

Alternative migration option - not recommended

Add @playwright/browser-chromium, @playwright/browser-firefox and @playwright/browser-webkit as a dependency. These packages download respective browsers during npm install. Make sure you keep the version of all playwright packages in sync:

// package.json
{
  "devDependencies": {
    "playwright": "1.38.0",
    "@playwright/browser-chromium": "1.38.0",
    "@playwright/browser-firefox": "1.38.0",
    "@playwright/browser-webkit": "1.38.0"
  }
}
