module-specifier-resolver

This tool transforms your local TypeScript code that gives you to rewrite file extension of module specifier automatically.

transform examples

export { foo } from "./foo"
transform to
export { foo } from "./foo.(ts|tsx|d.ts)"
import { bar } from "./bar"
transform to
import { bar } from "./bar.(ts|tsx|d.ts)"

limitation

  • Can’t resolve paths alias of TypeScript compiler options.
  • Can’t resolve import() syntax, commonly called dynamic import.
  • Can’t keep newline of original source code.

tips

After you ran bin.ts, you should run npx tsc --noEmit due to check correctness of transformation by this tool.

  • tsconfig.json example
{
  "compilerOptions": {
    "moduleResolution": "bundler",
    "allowImportingTsExtensions": true,
    "noEmit": true
