Run Puppeteer with your local chrome browser (not Chromium)

How to run puppeteer tests with your local Chrome browser

  1. Find browser's executable path:
    Go to chrome://version/ (inside Chrome browser) and find "Executable Path" variable ("/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" in my case)
  2. Modify your script:
const browser = await puppeteer.launch({
    executablePath: '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome',
    args: ['--disable-blink-features=AutomationControlled'],
 headless: false,

How to fix regeneratorRuntime is not defined

Add line "browserslist": ["since 2017-06"] to your package.json file. Babel won't add polyfills for async/await, es6. So you don't need to install and add reneneratorRuntime (or babel-polyfill) to your bundle!

Пример, нужно дернуть какую-то стороннюю апиху https://my-awesome-api.haha
CORS настроен таким образом что ты не можешь это сделать со стороннего домена, а доступа
к серверу апихи нет (сторонеее апи же).
То можно использовать прокси-сервер для этого. CORS реализованы в браузере только.


npx local-cors-proxy --proxyUrl https://my-awesome-api.haha


Это тулза выдаст примерно следующее:
