What This Rule Detects

This rule detects repositories using webpack 5.x at a version below 5.50.

Why It Matters

webpack 5.50+ includes significant performance improvements:

• Faster incremental builds
• Better tree-shaking and dead code elimination
• Reduced memory usage during compilation
• Improved module federation performance
• Better caching behavior

Upgrading within the 5.x line is typically low-risk since webpack 5 maintains good backward compatibility within minor versions.

Suggested Action

Upgrade webpack to ^5.50.0 in your package.json. Review the webpack 5 changelog for any changes between your current version and 5.50.

Measurement

Compare CI build time before and after the upgrade. Verify that the build output and behavior remain unchanged.

Compatibility Notes

• webpack 5.x maintains good backward compatibility within minor versions
• Most projects can upgrade from 5.x to 5.50+ without major configuration changes
• Check for any deprecated APIs that may have been removed in newer versions
