Why and How We Migrated from AngularJS to VueJS

Description and use

Migrating from AngularJS to Vue.js improved maintainability, build speed, and developer experience.

Problem

The AngularJS application had become difficult to maintain and lacked modern features, leading to performance and developer productivity issues.

Outcome

The migration resulted in a more maintainable codebase, faster build times, and improved developer onboarding.

Workflow

• 1. Conducted a code audit to identify AngularJS components and services.
• 2. Created a migration plan prioritizing core features.
• 3. Set up a new Vue.js project with Vite and TypeScript.
• 4. Replaced AngularJS modules with Vue components and Composition API.
• 5. Migrated services to Vuex store modules.
• 6. Updated routing from ui-router to Vue Router.
• 7. Refactored templates to Vue single-file components.
• 8. Implemented unit tests with Jest and Vue Test Utils.
• 9. Performed integration testing and performance benchmarking.
• 10. Deployed the new Vue.js application and phased out AngularJS code.

Evidence

We decided to migrate from AngularJS to Vue.js because the former was becoming increasingly difficult to maintain and lacked modern features.
