Proposed fix: [webpack 5] "Module not found: Error: Can't resolve 'crypto'/'stream'/'buffer'..." with 'BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.'
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: First check whether the dependency has a browser build or can be replaced (often the import is accidental server code in client bundle). If a polyfill is really needed add resolve.fallback: { "crypto": require.resolve("crypto-browserify") } and install the package; to stub it use resolve.fallback: { "fs": false }. Globals like Buffer/process also need ProvidePlugin.
Option: Configure resolve.fallback [evidence: official_recommended_action]
Applies when: webpack 5 configs you control (CRA needs craco/react-app-rewired or eject)
Steps:
1. npm i crypto-browserify stream-browserify buffer
2. resolve: { fallback: { crypto: require.resolve('crypto-browserify'), stream: require.resolve('stream-browserify'), buffer: require.resolve('buffer/') } }
3. or set fallback to false for modules not needed in the browser
Expected: Build resolves the modules
