VitePress Moves Build to tsdown

By RepoJournal · Filed · About Vue.js · Composed from the cited sources · methodology

VitePress is rebuilding its pipeline, and your theme components will finally get real prop types.

VitePress is ditching the rollup and tsc combo for tsdown [1], a move that modernizes the TypeScript setup without changing the published package layout. The notable win: shipped `.vue` files are now plain JavaScript with real generated declarations, so theme components finally have proper prop types [2]. The release notes call out that the new build is "unbundled (`src/client/**/*.ts`), emitting pe," though the exact performance numbers are still pending [2]. Meanwhile, eslint-plugin-vue fixed a broken CI workflow that had been failing with `Cannot read properties of null (reading 'querySelectorAll')` [3], caused by a `:scope` selector that never matched a DocumentFragment [4]. That fix keeps the deprecated HTML elements check running, so your linting rules stay accurate [4]. The rest of the activity is housekeeping: formatting and icon cleanup [5] and rolldown dedupe . Four commits and two PRs across the repos, so this is a maintenance day, but the VitePress build shift is one to watch.
