Accelerate TypeScript Migration with GitLab Duo Workflow

Refactoring JavaScript to TypeScript Using GitLab Duo Workflow

Modernising legacy JavaScript codebases has long been a challenge for development teams striving for better maintainability, improved type safety, and a more robust developer experience. With the new GitLab Duo Code Suggestions and GitLab Workflow integration, transitioning your code from JavaScript to TypeScript is now faster, safer, and more efficient than ever.

GitLab Duo leverages AI-powered assistance directly within your existing workflow to help teams automate and accelerate the refactoring process. Through natural language prompts and context-aware code generation, GitLab Duo can provide inline, accurate TypeScript suggestions where needed most—reducing the overall manual effort when updating your applications.

The recent example provided by the GitLab team showcases how a simple front-end JavaScript application was migrated to TypeScript using GitLab Duo’s intelligent recommendations. Errors like dynamic return types and missing type declarations were automatically detected and resolved with Duo’s step-by-step suggestions. Developers retained full control of every change by confirming, editing, or requesting clarification from Duo inside the IDE or GitLab’s Web IDE.

This workflow helps maintain code quality with consistent, systematised upgrades, all while keeping work within the familiar GitLab environment—streamlining iteration, review, and deployment processes significantly.
