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",
...
},
...
}
