Migrating Incrementally
Adopt TS gradually: enable checks, annotate with JSDoc, migrate hot files first, and keep builds green during the transition.
Why incremental migration?
Goal: Ship while you migrate.
- Add checks without breaking builds
- Annotate with JSDoc
- Migrate hot files first
Plan the migration
- Start with JSDoc on JS files
- Keep changes small; one component at a time
- Focus on frequently edited files
- Use type aliases to reuse shapes
