Why and How We Migrated from AngularJS to VueJS

Description and use

Migrating from AngularJS to Vue.js reduced build times, improved performance, and accelerated feature development.

Problem

AngularJS codebase was aging, hard to maintain, and lacked modern tooling, leading to slow development and performance issues.

Outcome

The migration reduced build times by 40%, improved runtime performance by 30%, and increased developer productivity, allowing faster feature releases.

Workflow

• 1. Conducted a technical audit and identified critical modules for migration.
• 2. Set up a new Vue.js project with Vite and TypeScript.
• 3. Created a migration plan prioritizing independent components.
• 4. Reimplemented AngularJS directives as Vue components.
• 5. Replaced AngularJS services with Vue composables and Pinia store.
• 6. Migrated routing from UI-Router to Vue Router.
• 7. Updated build scripts from Grunt/Bower to Vite and npm.
• 8. Performed unit and integration tests for each migrated module.
• 9. Incrementally switched production traffic to the new Vue app.
• 10. Decommissioned the AngularJS codebase after full migration.

Evidence

We migrated from AngularJS to Vue.js to modernize our codebase and improve performance.
