Module not found: Error: Can't resolve 'crypto' in 'C:\
ERROR MESSAGE:
Compiled with problems:X
ERROR in ./node_modules/@solana/spl-name-service/dist/utils.js 16:17-34
Module not found: Error: Can't resolve 'crypto' in 'C:\Users\...\node_modules\@solana\spl-name-service\dist'
BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.
If you want to include a polyfill, you need to:
- add a fallback 'resolve.fallback: { "crypto": require.resolve("crypto-browserify") }'
- install 'crypto-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
resolve.fallback: { "crypto": false }
Where the problem started:
- I tried using getParsedNftAccountsByOwner() from: https://github.com/NftEyez/sol-rayz
- Then, I got this error message.
My project:
- getParsedNftAccountsByOwner()
- React, Typescript project
- Libraries used: @solana/web3.js | @nfteyez/sol-rayz
- webpack 5.67.0
Even though I was able to resolve these errors in a few minutes, the 'crypto' one is different:
Stream problem:

Module not found: Error: Can't resolve 'stream' in 'C:\Users\...\node_modules\cipher-base'
BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.

If you want to include a polyfill, you need to:

- install 'stream-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
resolve.fallback: { "stream": false }
assert problem:
ERROR in ./node_modules/@solana/spl-name-service/dist/utils.js 14:33-50
Module not found: Error: Can't resolve 'assert' in 'C:\Users\...\node_modules\@solana\spl-name-service\dist'
BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.
If you want to include a polyfill, you need to:
- add a fallback 'resolve.fallback: { "assert": require.resolve("assert/") }'
- install 'assert'
If you don't want to include a polyfill, you can use an empty module like this:
resolve.fallback: { "assert": false }
What I have done so far:
-
I tried performing the two suggestions from the error message, and it didn't work
-
I tried the first two solutions already:
"compilerOptions": { "baseUrl": "./", "paths": { "crypto": [ "node_modules/crypto-js" ] }
Module not found: Error: Can't resolve 'crypto'
-
I tried this solution:
"browser": { "crypto": false }
https://github.com/tensorflow/tfjs/issues/494#issuecomment-481636128
- I tried this solution: node-polyfill-webpack-plugin

I think that because your create react app (CRA) does not recognize your webpack.config.js. Your setting for polyfills is correct. Setting up node-polyfill-webpack-plugin itself is enough to load all node core polyfills.
In order to modify the webpack.config.js in CRA, you have to run
npm run eject
this will create a config directory and inside you will have webpack.config.js which has almost 1000 lines of code. Inside that file, setting up node-polyfill-webpack-plugin should be enough.
