playwright-cli route mocks support URL patterns and route management

Introduced 2026-02-04 · score 0.98

HOW TO USE IT

When you need frontend development or testing without a backend, use `playwright-cli route` to mock requests by URL pattern, then use `route-list` or `unroute` to manage routes.

playwright-cli route "**/api/users" --body='[{"id":1,"name":"Alice"}]' --content-type=application/json
playwright-cli route "**/api/data" --body='{"ok":true}' --header="X-Custom: value"
playwright-cli route-list playwright-cli unroute "<URL pattern>" playwright-cli unroute

WHY THIS HELPS

Mock backend responses while developing or testing a web application's frontend.

REQUIREMENTS AND LIMITATIONS

  • Version: v0.0.63
  • <pattern> (required): URL pattern to match; examples include `**/api/users`, `**/api/*/details`, `**/*.{png,jpg,jpeg}`, and `**/search?q=*`.
  • --status: HTTP status code for the mock response; release example uses `404`.
  • --body: Response body, such as a JSON string.
  • --content-type: Content type for the response, such as `application/json`.
  • --header: Custom header in `Name: Value` format.
  • --remove-header: Comma-separated request headers to strip, such as `cookie,authorization`.
  • unroute <pattern>: Remove routes matching a URL pattern; omit the pattern to remove all routes.
  • Routes target URL patterns; the spans describe glob-style pattern support.
