How do I change `src` folder to something else in create-react-app

You can use react-app-rewired to override react paths configuration. In my case, I can change the paths in config-overrides.js file

const path = require('path');module.exports = {    paths: function (paths, env) {                paths.appIndexJs = path.resolve(__dirname, 'mysrc/client.js');        paths.appSrc = path.resolve(__dirname, 'mysrc');        return paths;    },}

I know this is an old question but I'm still gonna post my solution since it might help someone.

I got it working by doing the following:

1. Run npm run eject. This exposes some internal configuration stuff from create-react-app
2. Open your package.json and edit the respective regexes under jest.collectCoverageFrom and jest.testMatch to match your test path
3. Alter the paths for appSrc, appIndexJs and testsSetup in the config/paths.js file

Not sure if this answers your question but I'll give it a shot. My directory structure looks like this:

/root--/app----/build----/public------index.html----/src------index.jsapp.jspackage.js

My /root/package.json has this in it:

  "scripts": {    "build": "cd app && npm run build",    "start": "node app.js",    "serve": "cd app && npm run start"  },  "dependencies": {    "express": "^4.8.0",    "react": "^16.2.0",    "react-dom": "^16.2.0",    "react-router": "^4.2.0",    "react-router-dom": "^4.2.2",    "react-scripts": "^1.0.17"  },

and my /root/app/package.json looks like this:

  "scripts": {    "build": "react-scripts build",    "start": "set PORT=3000 && react-scripts start"  },  "dependencies": {    "react-scripts": "^1.0.17"  }

To run the development version of Reactjs, in the /root I can just npm run serve to serve up the dev version.

I am using node and express, so to run the production version of Reactjs, in the /root I can just npm run build to create the /root/app/build directory. I have a router that looks like this:

var options = {root : config.siteRoot + '/app/build'};mainRte.all('/', function(req, res) {    console.log('In mainRte.all Root');    res.sendFile('index.html', options);});

so when I run /root/app.js in node and surf to "/" it opens up /root/app/public/index.html and then /root/app/index.js.

Hopefully that helps.
