bun-plugin-dts

A Bun plugin for generating .d.ts files.

Install

bun add -d bun-plugin-dts

Usage

import dts from 'bun-plugin-dts'

await Bun.build({
  entrypoints: ['./src/index.ts', './src/other/foo.ts'],
  outdir: './dist',
  plugins: [
    dts()
  ],
})

// Generates `dist/index.d.ts` and `dist/other/foo.d.ts`

Options

This plugin utilizes dts-bundle-generator internally, allowing you to easily customize its behavior by passing specific options for dts-bundle-generator.

type Options = {
  libraries?: LibrariesOptions;
  /**
   * Fail if generated dts contains class declaration.
   */
  failOnClass?: boolean;
  output?: OutputOptions;
  compilationOptions?: CompilationOptions;
}

   * Used types will be inlined into the output file.

   * Array of package names from node_modules to import typings from.
   * Used types will be imported using `import { First, Second } from 'library-name';`.
   * By default all libraries will be imported (except inlined libraries and libraries from @types).
   */
  importedLibraries?: string[];
  /**
   * Array of package names from @types to import typings from via the triple-slash reference directive.
   * By default all packages are allowed and will be used according to their usages.
   */

   * Sort output nodes in ascendant order.

   */
  respectPreserveConstEnum?: boolean;
  /**
   * By default all interfaces, types and const enums are marked as exported even if they aren't exported directly.
