Angular 10 introduces significant improvements, but migrating existing projects requires careful steps. Here's a quick overview:

Key Migration Steps

  1. Upgrade Angular CLI

    • Run npm install -g @angular/cli@10.0.0 to update tools.
    • Use ng update for automated package upgrades.
      ⚠️ Note: Check for breaking changes in Angular 10 Release Notes

  2. Update Dependencies

    • Ensure @angular/core and other packages are compatible with Angular 10.
    • Replace deprecated APIs (e.g., Renderer with Renderer2).
    • 🛠️ Use Angular Migrate Tool for code analysis.

  3. Test Thoroughly

    • Run unit and end-to-end tests after migration.
    • Verify compatibility with third-party libraries.
    • 🧪 Use Angular Test Suite for validation.

Common Challenges

  • Compatibility Issues: Some legacy libraries may require updates.
  • Build Errors: Check tsconfig.json for Angular 10-specific settings.
  • Performance Gains: Leverage new features like Ivy for faster rendering.

Best Practices

  • 📝 Document changes made during migration.
  • 🔄 Maintain a backup of your project before upgrading.
