Setup: `npm install && npx playwright install` (downloads {chromium, firefox, webkit} (742 MB) to cache in home ([doc](https://playwright.dev/docs/browsers#managing-browser-binaries))).
Use `npm run login` which opens a browser where you can login. When closing the browser, it writes a file `auth.json` containing cookies that should keep you logged in for some time (`expires` in a month?).
<!-- Use `npm run login` which opens a browser where you can login. When closing the browser, it writes a file `auth.json` containing cookies that should keep you logged in for some time (`expires` in a month?). -->
Then use `npm start` to run Chrome in headless mode to claim the current free game.
Use `npm start` to start Chrome to claim the current free games.
The first time, the script will wait for you to login. Instead of redirecting back, the website seems to just reload the login URL. Go to https://www.epicgames.com/store/en-US/free-games manually, or restart the script.
If something goes wrong, use `PWDEBUG=1 npm start` to [inspect](https://playwright.dev/docs/inspector).
