Why Migrate to TypeScript?

Catch type errors and null references before runtime
Enhanced IDE autocomplete, refactoring, and navigation
Self-documenting code with explicit type annotations
Safer refactoring with compile-time validation
Improved team collaboration with typed contracts
Incremental adoption without halting feature development
TypeScript's compiler identifies type mismatches, undefined properties, and null reference errors during development rather than in production. Studies show 15% of JavaScript bugs are type-related errors that TypeScript catches immediately. Your IDE displays errors inline as you code, providing instant feedback before you even save the file, dramatically reducing debugging time and production incidents.

The TypeScript Advantage

What You Gain with TypeScript

Our Migration Strategy

A phased, file-by-file approach that maintains development velocity and allows for gradual adoption.

Tooling & Configuration

Set up TypeScript compiler, configure tsconfig.json for incremental adoption, integrate with existing build tools (Webpack, Vite, etc.), and establish linting rules.

Incremental Migration & Types

Convert files from .js to .ts in dependency order (leaf nodes first), add type annotations gradually, create type definitions for third-party libraries (@types), define interfaces for internal APIs, migrate PropTypes to TypeScript interfaces, and build shared type libraries.

Team Training & Support

Provide TypeScript best practices documentation, pair programming sessions for knowledge transfer, code review guidance, and migration runbooks for the team.

Migration Benefits

The measurable impact of TypeScript adoption.

Fewer Runtime Errors

-40%
Catch type mismatches, null references, and undefined errors at compile time, reducing production bugs by up to 40%.

Faster Refactoring

3x+
Confidently rename, restructure, and refactor with compile-time validation. IDE-powered refactoring becomes safe and fast.

Better Developer Experience

+35%
Enhanced autocomplete, inline documentation, and instant feedback improve productivity and reduce cognitive load.

Easier Onboarding

Faster
New team members understand APIs instantly through type signatures. Self-documenting code reduces knowledge transfer time.
