[BUG] Install instructions fail when using bun (create script uses npm instead of bun)

[jsonMartin]

I'm trying to set up Playwright in my NextJS 14 project (which is built using a bun monorepo).

Unfortunately, the initial install step is failing when using bun because the install script tries to use npm package manager instead of bun. This is completely failing in a monorepo setup, because npm can't handle it. But even if the install step initially did work installiing via npm, then I'm assuming it still wouldn't correctly work with bun's lockfile as it's using a different package manager.

System info

• Playwright Version: [v1.41.2]

Bun is not supported by Playwright.

Hey @pavelfeldman , from what I see it appears that the blocking issues preventing bun from working were closed as resolved 2 weeks ago: oven-sh/bun#4751

After a little more tinkering I was able to get this working with bun successfully. The hard part was just getting it installed properly: yarn create also failed for me (because it didn't like the bun monorepo), but pnpm create worked to create the Playwright install files (I just discarded the lockfile afterwards).

Calling via the bun cli, the sample tests work just fine for me:

$ bunx playwright test

Running 6 tests using 6 workers
  6 passed (4.0s)

To open last HTML report run:

  npx playwright show-report

[edit]: I tested bunx playwright test and bunx playwright show-report and both work successfully. It does not work when I use npx playwright test and npx playwright show-report (likely due to monorepo), so bun's runtime appears to be working successfully.

Would you reconsider marking this as complete (or create a new issue) until there is a better solution? Even if bun has no plans to be officially supported, at least putting some documentation on the website would be helpful 🙏🏼
