rollup-plugin-dts-bundle-generator

Just a small plugin that wraps the dts-bundle-generator CLI application to ease the integration in rollup builds.

dts-bundle-generator

All the heavy lifting in this plugin is done by the dts-bundle-generator CLI application.

dts-bundle-generator was created as zero-config solution to generate a single, flattened .d.ts file that contains no further declarations than those that are exported by the specified entry file and its descendants.

I am NOT affiliated with or a maintainer of dts-bundle-generator.

If you're using this plugin and find it helpful, please consider a donation to the authors of the dts-bundle-generator CLI application to sustain their efforts.

Usage

Installation:

npm i -D rollup-plugin-dts-bundle-generator

In your rollup configuration:

const config = {
  ...
  plugins: [..., generateDtsBundle(options)],
  ...
}

If the options are omitted / undefined, the plugin attempts to derive reasonable defaults from the input / output values of the rollup configuration.

The following options are currently supported:

export type PluginConfig = {
  entry?: EntryPointConfig[]         // see https://github.com/timocov/dts-bundle-generator/blob/master/src/bundle-generator.ts
  compilation?: CompilationOptions   // see https://github.com/timocov/dts-bundle-generator/blob/master/src/bundle-generator.ts
  outFile?: string                   // custom output filename, e.g. "types/index.d.ts"
}

Motivation

A simple, bundled export of TypeScript typings in rollup builds has been among the most requested features for years and is still difficult to accomplish without plugins, out of which many seem quirky and difficult to use.

Discussion:

• Generating d.ts files in TypeScript projects
• Tools comparisson (dts-bundle-generator, api-extractor, rollup-plugin-dts, npm-dts)
• Use-cases of incorrect result for dts-bundle-generator
