Cursor deployment

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
Webpack config syntax errorUnexpected tokenCannot find moduleConfiguration invalid

Common Causes

  1. Missing closing braces or brackets in config object
  2. Rule syntax changed (loader vs loaders, use vs loader)
  3. Plugin instantiation syntax wrong (missing 'new')
  4. Entry/output points changed to invalid paths
  5. 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'].

Frequently Asked Questions

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.
