# TypeScript ESM Import Fix

TypeScript with ES modules requires explicit `.js` extensions in relative imports —
even though the source files are `.ts`.

1. Add a `.js` extension to every relative import (`./foo` → `./foo.js`).
2. Keep it `.js` even when the file on disk is `foo.ts`.
3. Run `tsc --noEmit` and confirm there are no module-resolution errors.

If you can't touch every import, set `"moduleResolution": "bundler"` in `tsconfig.json`.
