Playwright Runner

Install

From the Zed extension registry

Section titled “From the Zed extension registry”

Open zed: extensions and search for Playwright Runner. The listing is under review in the Zed extension registry (zed-industries/extensions#7975). Until the review completes, install from source.

The extension installs the language server package playwright-zed-language-server from npm on first use. Nothing is bundled.

From source

Section titled “From source”

For the unreleased version, or while the registry listing is under review:

  1. rustup target add wasm32-wasip2
  2. cd server && npm install && npm run build in a clone of the repository
  3. In Zed, run zed: install dev extension and pick the repository’s root.

If you installed a dev extension before 0.4.0, it is listed as “Playwright for Zed” with the id playwright; uninstall it in zed: extensions first, otherwise two Playwright language servers start on the same files.

After an update or reinstall

Section titled “After an update or reinstall”

Files that are already open when the extension is installed are picked up without closing and reopening them. One exception: after an update, a reinstall, or a rerun of zed: install dev extension in the same Zed session, Zed keeps the Playwright server stopped. It marks the server as manually stopped when the old extension version unloads and never clears the mark, so no file is served, open before or after. Run editor: restart language server from any TypeScript or JavaScript file of the project, or restart Zed; closing and reopening files does not help. Tracked in Zed as zed-industries/zed#60405.

Next: First run.
