Webpack Configuration Broken After Edit
After Cursor refactored your webpack configuration, the build process fails with syntax errors or configuration errors. The webpack config is malformed.
The configuration syntax or structure was changed incorrectly.
Error Messages You Might See
Webpack config syntax error
Unexpected token
Cannot find module
Configuration invalid
Common Causes
- Missing closing braces or brackets in config object
- Rule syntax changed (loader vs loaders, use vs loader)
- Plugin instantiation syntax wrong (missing 'new')
- Entry/output points changed to invalid paths
- Loader configuration object malformed
How to Fix It
Verify syntax with node -c webpack.config.js. Check structure: module.exports = {entry, output, module: {rules}, plugins}. Plugins need 'new': new HtmlPlugin({}). Loaders use 'use': use: ['style-loader', 'css-loader'].

What's the difference between loaders and plugins?
Loaders transform files (css -> js). Plugins do everything else (minimize, extract, generate HTML).
How do I debug webpack?
Run with --mode development for readable output. Use webpack --debug. Check final bundle structure with webpack-bundle-analyzer.
