Expo: Default browser for expo start

Question

Is there a way to change the browser in which the Expo interface ( http://localhost:19002/ ) opens after expo start ?

My default browser is Firefox, which I use for my private life. My work and coding browser is Chrome. Is there a way to tell Expo to use Chrome by default?

Answer 1

React native use chrome and chrome-debug-tool, because firefox's devtool is the big garbage. I recommend you to use chrome when you develop app by expo.

Answer 2

expo start looks at the BROWSER environment variable before using the default browser so you can switch to Chrome just by setting that env var before calling expo start

As a raw command it looks like this for Windows:

set BROWSER=%ProgramFiles(x86)%\Google\Chrome\Application\chrome.exe && expo start

For my workflow I have just updated package.json so the yarn run start script does it for me:

{
  "main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "set BROWSER=%ProgramFiles(x86)%\\Google\\Chrome\\Application\\chrome.exe && expo start",
    ...
  },
  ...
}

最简单的方法是复制您的“http://localhost:19002/”并将其粘贴到您要打开项目的浏览器中
