npm run build failing-CodePudding

I am trying to build my react and node.js web app but fail to build ever since fixing packages.

i get the following error


Module not found: Error: Can't resolve 'fs' in 'my-app/node_modules/dotenv/lib'


npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] build: `react-scripts build`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the [email protected] build script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

I have tried to clear the cache of node_modules, remove package-lock.json, re install with npm and re-build, but nothing works.

Does anyone know how to solve this please?

Node Core Modules like fs won't work in the browser because they require binaries that aren't present in the browser. It apparently has been stubbed out of create-react-app, as per this Github issue.

The web doesn't have a filesystem, so it makes sense it won't ever work. Unfortunately for you, it means you should find a workaround. What were you trying to achieve with fs ?

This may be a short hand fix, but i removed the dotenv package and loaded my env variables into the Azure config variables.
