Npm run build runs forever ?

Hi everyone!

Thanks for creating this! Allowing us to try CRA2. I have made the switch and npm start works great but somehow when its time to create a build it appears the build stop somewhere.

Is there any way to debug what is happening? My reason for customize-cra was mobx. Thinking of going decorator-less right now.

tried this config:

const rewireMobX = require('react-app-rewire-mobx');
const { override, addDecoratorsLegacy, disableEsLint, addBundleVisualizer, addWebpackAlias, adjustWorkbox } = require("customize-cra");
const path = require("path");

/* config-overrides.js */
module.exports = function override(config, env) {
  config = rewireMobX(config, env);
  return config;
}

module.exports = override(
  addDecoratorsLegacy(),
  disableEsLint(),  
);

and this one

const { override, addDecoratorsLegacy, disableEsLint, addBundleVisualizer, addWebpackAlias, adjustWorkbox } = require("customize-cra");
const path = require("path");

module.exports = override(
  addDecoratorsLegacy(),
  disableEsLint(),
 
);

Did i get something wrong ?

Turns out disabling sourcemap allows it to build !

GENERATE_SOURCEMAP=false yarn build

Not sure what happened here but at least I can build now.

Glad you figured it out!
