We Migrated from AngularJS to React/Redux in 2 Weeks

Описание и применение

Перенос AngularJS в React/Redux за 2 недели: план, шаги и результаты.

The legacy AngularJS application was difficult to maintain, had performance issues, and lacked modern tooling.

The migration was completed in two weeks, reducing build times by 40%, improving load performance, and enabling faster feature development.

1. Conducted a code audit to identify reusable components and services.
2. Created a migration plan prioritizing critical features.
3. Set up a new React/Redux project with TypeScript and ESLint.
4. Re‑implemented AngularJS services as Redux thunks and selectors.
5. Converted AngularJS directives to React components, preserving templates where possible.
6. Migrated routing from UI-Router to React Router.
7. Implemented unit and integration tests using Jest and React Testing Library.
8. Performed incremental integration testing and user acceptance testing.
9. Deployed the new application to staging and monitored performance metrics.
10. Switched traffic to the new React/Redux app and decommissioned the AngularJS codebase.
