We Rewrote Our Angular 18 App in React 20 and Increased Developer Velocity by 40% Last quarter, our engineering team made the bold call to rewrite our 3-year-old Angular 18 production application in React 20. After 6 months of development, we cut over to the new stack with zero downtime, and the results have exceeded our expectations: we’ve measured a 40% increase in developer velocity, alongside major gains in performance and team satisfaction. Why We Migrated Away from Angular 18 Our Angular 18 app had grown to over 400 components, with a mix of NgRx for state management, custom RxJS operators, and a complex dependency injection tree. While Angular served us well early on, we hit several scaling pain points: Build times ballooned to 8+ minutes for full production builds, slowing CI/CD pipelines and developer feedback loops.
