BuildConfig.dts

dts?: boolean

Write a TypeScript declaration file (.d.ts) for each source file, and each JavaScript output file once more with its types kept (index.js and index.aot.ts). The entrypoints and everything they import are type checked first, as with check. Equivalent to --dts in the CLI.

bun compile compiles a package from its .aot.ts files where the "aot" condition in the "exports" of its package.json names them. Every other tool reads index.js and index.d.ts. "compilerOptions" in the package.json says how strict they are. Without it they are checked as strict.

The files are in outputs with kind: "asset". They are written to outdir if there is one. Can't be used with compile.

await Bun.build({
  entrypoints: ['./src/index.ts'],
  outdir: './dist',
  dts: true,
});
// dist/index.js, dist/index.d.ts, dist/index.aot.ts
