The Pragmatic Migration: Moving from AngularJS to Angular v22

Short summary

AngularJS is end-of-life, requiring migration to modern Angular v22 for security and performance. Rather than risky Big Bang rewrites that halt feature development, use ngUpgrade to run both frameworks side-by-side, incrementally modernizing components. Angular v22 delivers major improvements: zoneless architecture reduces overhead, signals enable fine-grained reactivity, and OnPush change detection is now default.

• •AngularJS EOL creates security and modernization imperative for legacy applications
• •ngUpgrade enables safe incremental migration without halting feature delivery
• •Angular v22 offers significant performance gains through zoneless design and signal-based state management
