rsbuild-plugin-dts

An Rsbuild plugin to emit declaration files for TypeScript which is built-in in Rslib.

Using in Rslib

Read DTS and lib.dts for more details.

Using in Rsbuild

Install:

npm add rsbuild-plugin-dts -D

Add plugin to rsbuild.config.ts:

// rsbuild.config.ts
import { pluginDts } from 'rsbuild-plugin-dts';

export default {
  plugins: [pluginDts()],
};

Options

bundle

• Type: boolean
• Default: false

Whether to bundle the DTS files.

If you want to bundle DTS files, you should:

1. Install @microsoft/api-extractor as a development dependency, which is the underlying tool used for bundling DTS files.

npm add @microsoft/api-extractor -D

2. Set bundle to true.

pluginDts({
  bundle: true,
});

distPath

• Type: string

The output directory of DTS files. The default value follows the priority below:

1. The distPath value of the plugin options.
2. The declarationDir value in the tsconfig.json file.
3. The output.distPath.root value of Rsbuild configuration.

pluginDts({
  distPath: './dist-types',
});

build

• Type: boolean
• Default: false

Determines whether to generate DTS files while building the project references. This is equivalent to using the --build flag with the tsc command. See Project References for more details.

When this option is enabled, you must explicitly set declarationDir or outDir in tsconfig.json in order to meet the build requirements.

abortOnError

• Type: boolean
• Default: true

Whether to abort the build process when an error occurs during DTS generation.

By default, type errors will cause the build to fail.

When abortOnError is set to false, the build will still succeed even if there are type issues in the code.

pluginDts({
  abortOnError: false,
});

dtsExtension

• Type: string
• Default: '.d.ts'

The extension of the DTS file.

pluginDts({
  dtsExtension: '.d.mts',
});

autoExternal

• Type: boolean
• Default: true

Whether to automatically externalize dependencies of different dependency types and do not bundle them into the DTS file.

The default value of autoExternal is true, which means the following dependency types will not be bundled:

• dependencies
• optionalDependencies
• peerDependencies

And the following dependency types will be bundled:

• devDependencies

pluginDts({
  autoExternal: {
    dependencies: true,
    optionalDependencies: true,
    peerDependencies: true,
    devDependencies: false,
  },
});

banner

• Type: string
• Default: undefined

Inject content into the top of each DTS file.

pluginDts({
  banner: '/** @banner */',
});

footer

• Type: string
• Default: undefined

Inject content into the bottom of each DTS file.

pluginDts({
  footer: '/** @footer */',
});
