Blank page after running build on create-react-app

Trying to deploy create-react-app on netlify, however my build is blank page. I'm using .env file for loading firebase api key is that a problem for build?

Even when I tried to open it locally on my computer its blank page and it outputs an error in console: "Loading failed for the with source “file:///event-app/static/js/main.108757a0.js”"

package.json: https://gist.github.com/Verthon/f82371ad2bb636b2e95c5b7697aa0bb5

➜  event-app git:(master) ✗ npm run build

I solved the problem by setting

"homepage": "."

in package.json according to this doc

If you're using react-router and trying to open index.html directly in the browser (or using electron, which essentially does that), in addition to setting homepage as others have suggested, replace your BrowserRouter with a HashRouter.

I was trying to build an electron app using create-react-app. When running in development everything was fine, but when I built the CRA and then pointed the electron app to the index.html file, I got the blank page.

I found that that was exactly the same as opening the index.html file directly in the browser. Everyone says "set homepage in package.json", but I already had that. So what now!?

I eventually figured out that the problem was react-router. I was using a BrowserRouter. Switching to a HashRouter solved the problem for me.

Add

"homepage": ".",

in your package.json then build again.

Just as @Verthon said putting the "homepage": ".", in your package.json file, in the top level like this:

{
     "name": "myApp",
     "homepage": ".",
     // all other package.json stuff...
}
