Module not found can't resolve 'fs' in node_modules\tempa-xlsx

[Srivastava295]

We tried updating react-scripts from 4.0.3 to 5.0.0 with react-data-export 0.6.0 and xlsx 0.17.2, and when we try to build it fails with the error Module not found: Error: Can't resolve 'fs' in react-data-export\node_modules\tempa-xlsx

What fix needs to be applied to maintain react-scripts version 5.0.0? Thanks!

I have also the same problem. I tried to use older version but it is still the same. Do you have any workaround to solve this problem?

Thanks!

I'm having this problem too. I made the build work by adding this lines to the 'resolve' field of webpack.config.js file (which is located in node_modules/react-scripts/config):

fallback: { "fs": false, "crypto": false },

Of course, this is a temporary fix.

The problem can be fixed definitively by replacing tempa-xlsx with xlsx in the package's source code. I'll try to make a pull request fixing it soon.

Any updates for the fix? Also will I be able to export if I add the above code?

I guess the package is not being maintained anymore. If you add the above code, it will work as long as you don't cause your webpack.config.js file to lose the added lines (e.g. by re-creating your node_modules). This may make it difficult to use this package in a continuous integration environment, because of the manual edit of webpack.config.js you have to make

Any updates?

I switched from NPM to YARN and everything works perfectly. NPM has a lot of problems, try switching to YARN if you can. Maybe it can solve your problem

Hi guy, any fix on this bug yet?

[Natnaelh]

Adding
"browser": { "fs": false, },
in the package.json file fixed it for me.

I added the following dependencies to package.json:

"react-data-export": "^0.6.0"
"xlsx": "^0.17.0"
"tempa-xlsx": "0.0.1"
Then, I deleted the node_modules and build folders.

After that, I ran these commands in order:

bash
Kodu kopyala
npm cache clear --force
npm install
npm run build
This resolved the issue I was facing.

"tempa-xlsx": "0.0.1"
