AngularJS to Angular Migration
Migrate your application from the deprecated AngularJS technology to the powerful and versatile Angular for new opportunities and improved performance of your business.
Why your business should consider moving from AngularJS to Angular?
- Future-proofing with Angular:
As AngularJS is now deprecated, the migration becomes essential for longevity. Angular, backed by Google’s Long-Term Support (LTS) and updated biannually, ensures lasting functionality and relevance. - Scalability prospects:
Angular’s reusable, modular components make it easier to scale your application as your business grows.
- Efficient resource allocation:
Angular Material UI provides ready-to-use design components, allowing for faster and user-centric development and bringing polished results without the need to start from scratch. - Minimizing third-party tool dependence:
Angular’s built-in tools (CLI and IDE) reduce the need for third-party paid software, streamlining development.
- Enhanced speed and stability:
Web Workers support background processing, and server-side rendering boosts load times, while TypeScript improves error detection, ensuring a smoother, more reliable experience. - Optimized user experience:
Angular’s support for Progressive Web Apps (PWAs) and Ahead-of-Time (AOT) compilation offers fast, native-like user flow.
AngularJS vs. Angular
AngularJS and Angular, while sharing a common background, differ significantly in their architecture, language, performance, mobile support, dependency injection, and modularity.

- High downtime and potential business disruptions.
- Significant time and resource investment.
- Risks not justifying the effort if the transition impacts other ongoing projects or features.
- Large-scale projects that must operate consistently.
- Complex applications that require a gradual, risk-controlled approach.
- Projects that only allow for minimal downtime and ongoing feature updates.
- Supports a hybrid environment, running AngularJS and Angular at the same time.
- Allows you to carry out a gradual migration, transferring features incrementally.
- Reduces risk of breakdowns and gives you more time to address migration challenges.
- May take longer to complete the migration process.
- Requires you to manage both frameworks within a single project.

AngularJS to Angular migration process: How we build it at TYMIQ
The migration process varies for each project, depending on the starting point (current application setup) and the specific goals of the migration. Taking the full project scope into account, we divide the process into two stages: preparation and migration. Each stage includes key steps in which we provide our assistance when you entrust us with your app modernization.
We evaluate your AngularJS app to understand its structure, dependencies, and functionality. One of our key purposes here is to identify critical components and services to prioritize during migration.
We develop a detailed plan with timelines, resource allocation, and testing schedules. We distribute responsibilities and ensure time for validation to maintain stability.
We introduce TypeScript using the @types/angular package. Our task is to gradually migrate modules and leverage TypeScript’s error-checking capabilities for improved code quality.
Our team enables AngularJS and Angular to run concurrently. This toolkit allows for gradual updates and minimizes risks of disruption.
We utilize the downgrade feature to make Angular components usable in AngularJS. At this step, we rewrite or refactor services and components for compatibility with Angular standards.
By adopting tools like ngUpgrade and UI-Router, we ensure smooth navigation and maintain user experience during the migration.
- We help update Node.js and npm to the latest stable versions.
- Installing Angular CLI and configuring your development environment.
- We set up a hybrid environment to allow both frameworks to function together during migration.
- Installing necessary dependencies for ngUpgrade.
- Identifying components. Starting with simple, reusable ones.
- Migrating components: Refactoring or rewriting each component one at a time.
- Identifying services: Beginning with standalone services with minimal dependencies.
- Migrate services: Rewriting services to align with Angular’s DI system.
- Setting up Angular routing: We use RouterModule in app-routing.module.ts.
- Gradually migrating routes: Transitioning routing incrementally while maintaining app functionality.
- Directives: Replacing AngularJS directives with Angular directives, downgrading them for use in AngularJS as needed.
- Filters to pipes: Replacing AngularJS filters with Angular pipes.
- Unit testing: Testing each migrated component, service, and directive with Jasmine/Karma.
- Integration testing: Ensuring AngularJS and Angular components work together seamlessly.
- End-to-end testing: Validating app functionality with Protractor.
- Removing AngularJS dependencies: Eliminating remaining AngularJS-related code.
- Updating Bootstrap: Modifying main.ts to exclusively bootstrap the Angular app.
- Optimizing: Refactoring for performance and following Angular best practices.
- Building the application: We use Angular CLI to create a production-ready build.
- Deploying to server: Testing the deployed application to ensure stability and functionality.

LearnPotential hurdles of migrating large applications from AngularJS to Angular
Migrating a large application from AngularJS to Angular often involves complexities and advanced tasks for engineers. At TYMIQ, we understand these challenges and offer tailored solutions to address them. Here are some of the key complexities:
Challenge: Large applications tend to have intricate, interconnected codebases with numerous dependencies and custom directives.
Response: To manage this, migration strategies often involve auditing the codebase to map out critical components and dependencies. Utilizing tools like ngUpgrade enables phased implementation that allows for the two versions AngularJS and Angular to run side-by-side.
Challenge: The difference in state management approaches between AngularJS and Angular can complicate the transition of custom or complex logic.
Response: The typical response to this issue has been to map the existing state structure and align it with Angular’s tools like Services or advanced libraries like NgRx.
Challenge: Angular’s DI system offers greater modularity and flexibility compared to AngularJS, which complicates adapting existing services and dependencies.
Response: Common practices involve refactoring AngularJS services to fit Angular’s hierarchical DI model.
Challenge: Ensuring that the migrated application retains or improves performance, as AngularJS and Angular optimize applications differently.
Response: Angular’s advanced features like Ahead-of-Time (AOT) compilation, lazy loading, and tree-shaking often help optimize performance. Also, performance monitoring tools such as Angular DevTools help identify bottlenecks, enabling the refinement of change detection strategies.
Challenge: Moving from AngularJS to Angular brings in new technologies like TypeScript and architectural adjustments, which can be challenging for developers unfamiliar with them.
Response: Many organizations address this by investing in structured training programs, including workshops and tutorials. Encouraging collaborative practices like pair programming and cross-team knowledge transfer accelerates skill development.
Challenge: The extensive code changes involved in migration heighten the risk of bugs and regressions.
Response: A comprehensive testing strategy typically includes unit, integration, and end-to-end tests using Angular-compatible tools such as Jasmine and Karma. Automation through CI/CD pipelines ensures continuous testing, helping to maintain application quality.
