What problem does it solve?

This guide helps teams migrate JavaScript projects to TypeScript progressively, reducing risk and downtime by sequencing changes and validating behavior in stages.

Core Features & Use Cases

  • Progressive three-stage migration strategy (allowJs → checkJs false → strict) to let existing JS code run under TS with minimal changes.
  • Layered tsconfig approach (base config, plus dedicated node and app configs) with practical examples for Vue 3 frontends, Express backends, and Node tooling.
  • JSDoc-based typing and transitional patterns to gradually add type safety when files or modules cannot be converted immediately.

Quick Start

Begin with Stage 1 by enabling allowJs and turning off checkJs, then gradually add types to key modules as you verify behavior.
