build by using command parcel --no-cache ./index.html
Error Uncaught SyntaxError: Unexpected token < in browser console

Please provide more information about your Project. I've started using parcel with React & Firebase and it seems to work perfectly.
For your interest, this is the build line I am using:
build:
cross-env NODE_ENV=production parcel build ./src/index.html --public-url ./
and locally run:
parcel ./src/index.html
@liranbg are you using reserved URLs for Firebase configuration? If yes, could you share how you got them working with Parcel; if no, please also share how you're including Firebase config for your setup.
@dinvlad I do not use reserved URLs.
'Firebase config' you mean the firebase.json file? if so, I do not include it anywhere in my code. it sits right in the root folder of my projects, and once I use the firebase cli tool, it detects it automatically.
Ok, that makes sense, thanks!
@liranbg Thank you for sharing your build line just wanted to add if anyone is using firebase just change the public in the firebase.json to dist/ like this :
"public": "dist/"
Mine is working now.
