tsdown + tsgo + Vue #

Build a Vue component library with JavaScript and TypeScript declarations.

Both rolldown-plugin-dts and the Vue content mapper are still under development and are not yet stable. APIs and behavior may change.

pnpm install
pnpm build
pnpm typecheck
pnpm test:types

Output: dist/index.mjs and dist/index.d.mts.

Configuration #

• unplugin-vue compiles Vue components to JavaScript.
• tsconfig.json registers the Vue content mapper.
• tsdown uses generator: 'tsgo' with tsgo.runExternalCode: true.
• pnpm overrides rolldown-plugin-dts with 0.29.0-beta.2.

Vue mapper #

The mapper is not yet published to npm. vendor/ contains local builds of @vue/content-mapper and @vue/language-core from Vue Language Tools PR #6170, with the upstream MIT license.

The mapper uses TypeScript 6 internally; declaration generation and type checking use TypeScript 7.1.0-beta. No external checkout is required.

VS Code #

Install the recommended TypeScript 7 extension and reload the window. Workspace settings select the local TypeScript 7 package. Trust this workspace and approve the Vue content mapper when prompted to enable editor features.
