Module not found: Error: Can't resolve 'crypto' in 'C:\

Question

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:

ERROR in ./node_modules/cipher-base/index.js 3:16-43

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.
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: { "stream": require.resolve("stream-browserify") }'
    - 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:

1. I tried performing the two suggestions from the error message, and it didn't work

2. I tried the first two solutions already:

   "compilerOptions": { "baseUrl": "./", "paths": { "crypto": [ "node_modules/crypto-js" ] }

Module not found: Error: Can't resolve 'crypto'

3. I tried this solution:

   "browser": { "crypto": false }

https://github.com/tensorflow/tfjs/issues/494#issuecomment-481636128

4. I tried this solution: node-polyfill-webpack-plugin

https://stackoverflow.com/a/65556946/18007508

const NodePolyfillPlugin = require("node-polyfill-webpack-plugin")
module.exports = {
        // Other rules...
        plugins: [
            new NodePolyfillPlugin()
        ]
    } 

My Code: webpack.config.js

const HtmlWebpackPlugin = require("html-webpack-plugin");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const NodePolyfillPlugin = require("node-polyfill-webpack-plugin")
module.exports = {
  entry: "./src/components/index.tsx",
  target: "web",
  mode: "development",
  output: {
    path: path.resolve(\__dirname, "build"),
    filename: "bundle.js",
  },
  resolve: {
    extensions: [".js", ".jsx", ".json", ".ts", ".tsx"],
    fallback: {
      "crypto":require.resolve('crypto-browserify') ,
    } 
  },
  module: {
    rules: [
      {
        test: /\.(ts|tsx)$/,
        loader: "awesome-typescript-loader",

        test: /\.js$/,

      },
      {

      },
    ],
  },
  plugins: [
    new HtmlWebpackPlugin({

    new MiniCssExtractPlugin({

Answer 1

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.
