Angular 9.6 to 14 Key Changes Explained | Generated by AI
I’ll help you understand the key differences between Angular 9.6 and Angular 14. This spans several major versions, so there are quite a few important changes:
Ivy Renderer (solidified after Angular 9) Angular 9 introduced Ivy as the default rendering engine, and by Angular 14, it’s fully mature with better performance, smaller bundle sizes, and faster compilation.
Standalone Components (Angular 14) This is one of the biggest changes. Angular 14 introduced standalone components, directives, and pipes that don’t require NgModules. This simplifies the application architecture significantly and reduces boilerplate code.
Typed Forms (Angular 14) Forms are now strictly typed, providing better type safety and autocomplete in your IDE. This catches errors at compile time rather than runtime.
Performance Improvements Angular 14 has faster build times, improved tree-shaking, and better runtime performance compared to Angular 9.6.
TypeScript and Node.js Requirements Angular 14 requires TypeScript 4.6+ (vs TypeScript 3.7-3.9 for Angular 9), and Node.js 14.15+ (vs Node.js 10.13+ for Angular 9).
CLI Enhancements The Angular CLI has received many improvements including better error messages, auto-completion in the terminal, and streamlined commands.
Removed Features View Engine (the old renderer) was deprecated and removed, IE11 support was dropped, and older legacy features were cleaned up.
Optional NgModules With standalone components in Angular 14, you can build entire applications without using NgModules at all, though they’re still supported.
Would you like me to go into more detail about any of these changes, or are you specifically looking at migration considerations?
