Why and How We Migrated from AngularJS to VueJS

Description and use

The Holistics team migrated from AngularJS to VueJS to improve code maintainability and developer productivity. The migration involved rewriting components, services, and routing to leverage VueJS's modern architecture.

Problem

The development team needed to migrate their existing AngularJS codebase to VueJS due to AngularJS reaching end-of-life and to benefit from VueJS's lighter weight, simpler learning curve, and improved developer productivity.

Outcome

Successfully completed migration from AngularJS to VueJS, improving code maintainability, reducing bundle size, and enhancing developer productivity. The team benefited from VueJS's gentler learning curve and more intuitive API compared to AngularJS.

Workflow

• Assess the existing AngularJS codebase scope and complexity
• Plan the migration strategy (gradual vs. full rewrite)
• Set up VueJS development environment and build tools
• Identify core components that need migration first
• Migrate components one by one from AngularJS directives to VueJS components
• Replace AngularJS services with VueJS composables or plugins
• Migrate routing from AngularJS router to Vue Router
• Update state management approach
• Test migrated functionality thoroughly
• Deploy and monitor the migrated application
