Demystifying Ahead-Of-Time compilation in Angular
summary
Compares JIT vs AOT with concrete build steps and tooling: use ngc or the Angular CLI (or the webpack AOT plugin) to emit v8‑friendly code, run tree‑shaking/rollup and source‑map‑explorer to shrink bundles. Claims the template compiler can be ~45% of generated code and AOT cuts runtime boot/compile work (author measures roughly a ~50% smaller runtime compile cost: ~1s vs ~700ms in a simple app). Notes AOT requires statically analyzable code — export factory functions, avoid lambdas in module metadata and use public properties.
