🎭 Playwright CLI

Usage | Examples

Playwright CLI is a CLI wrapper around the Playwright library.

Playwright CLI is built to enable shell access to popular Playwright commands such as capturing screenshots, saving as PDF. But it is also useful if you want to see what your web page would look like in WebKit (Safari) while being on Window or Linux.

Install CLI as follows:

$ npm install --D playwright-cli

Print Playwright CLI help
