[Realm with Electron Using React] **Module** **not found** Error

[Yilmaz_Durmaz (Yılmaz Durmaz)]

**BREAKING CHANGE** **: webpack < 5 used to include polyfills for node.js core modules by default.**

[0] This is no longer the case. Verify if you need this module and configure a polyfill for it.

I guess “create-react-app@4” was using webpack 4.x and now it is highly possibly you have “create-react-app@5” with webpack 5.x. The error you get complaints about “fs” and “path” modules of nodejs and the part I quoted tells they are not included by default in the app’s packaging.

The error message also suggests you a solution in later lines, with path-browserify. please first try that and see if the error goes away.

@Alexander_Ye

[0] If you want to include a polyfill, you need to:

[0] - add a fallback 'resolve.fallback: { "path": require.resolve("path-browserify") }'

[0] - install 'path-browserify'
