Migrate AngularJS to Angular

Remove AngularJS End-of-Life Risk and Retain Business Continuity with AngularJS to Angular Migration

We convert AngularJS to Angular applications without halting delivery or initiating unnecessary rewrites. Legacy and Angular components run together to guarantee uninterrupted releases.

Corsac removes operational weaknesses stemming from digest cycles and legacy dependencies. Instead, Angular’s efficient change detection enables faster, more stable, and data-intensive UIs.

End-to-End AngularJS to Angular Migration Services

We conduct AngularJS to Angular migration not for cosmetic refactoring, but for future scaling. Without business disruption, we redesign the frontend structure instead of merely converting code and train your team to support and upgrade the Angular app.

modernization-solution

AngularJS Application Assessment

We analyze your AngularJS codebase, versions, modules, scopes, watchers, and performance weaknesses. Identify Angular equivalents for controllers, directives, and services. Compare ngUpgrade and phased rebuild strategies and reveal security, performance, and testing gaps.

Migration Strategy & Architecture Planning

We choose between a hybrid AngularJS + Angular approach or a clean-slate migration. Module boundaries, routing, and state management are determined. Migration is structured to protect production features, while frontend modernization is matched with backend and API upgrade.

Component & Module Migration

We transform legacy controllers and directives into Angular components, replacing $scope logic with reactive data flows. The UI is modularized for lazy loading and future expansion, while the full functional parity between the new and legacy UI is guaranteed.

State Management & Routing Migration

We migrate $rootScope and implicit state to explicit, predictable models. Reactive state is implemented via NgRx, signals, or simpler patterns where appropriate. Routing is rebuilt for reinforced performance, guards, and lazy-loaded modules.

Performance Optimization & Code Modernization

Our experts eliminate digest-cycle overhead, expedite rendering, change detection, and reduce bundle size. We remove legacy dependencies and polyfills while enforcing strict typing and linting for higher stability, performance, and code quality.

Testing, QA & Post-Migration Support

We rebuild test coverage with Angular TestBed, Jest, and Cypress or Playwright, preserving functionality and UX consistency. CI pipelines are optimized for speed and reliability, while migration documentation and knowledge are fully transferred to internal teams.

    Frequently Asked Questions

    AngularJS was an advanced tech stack in 2010. Since then, web development has significantly evolved. Today, you should convert AngularJS to Angular primarily because AngularJS reached end-of-life in 2021. Official support or updates are no longer available, so using it may pose risks to your security and compliance. Modern Angular versions offer remarkable performance improvements, enhanced developer experience, and a better ecosystem.

    To migrate from Angularjs to Angular safely, you should be aware of the common mistakes that may lead to risks and issues. Avoid rushing into migration without properly preparing the AngularJS application, as it can cause unnecessary complexity and errors. Make sure to test your app, because otherwise migration can cause painful breaks. Train your team, since Angular is significantly different from AngularJS.

    For large applications, a complete rewrite is not always necessary for Angular JS to Angular migration. We often apply an incremental (hybrid) migration to enable simultaneous operation of both frameworks. We transfer components and services one by one to guarantee smooth and uninterrupted operation. A full rewrite can be reasonable for small products that allow for quick transformation.

    AngularJS update can grant significant improvements. Better operation is attained thanks to faster rendering and smaller bundle sizes. You expand access to advanced features and tooling, including Angular CLI, AoT compilation, and mobile support. You can also enjoy continual support and guidance regarding the updates to further versions of the framework.

    We approach upgrading from AngularJS to Angular comprehensively, transforming your application for flexibility, security, compliance, and growth. Compliance is integrated into every stage of the modernization process, making technical progress reliable and safe. Our work is focused on meeting regulatory standards, from HIPAA and GDPR to SOC2 and ISO27001.
