rolldown 1.0.0-beta.57

v1.0.0-beta.57

on Node.js NPM

[1.0.0-beta.57] - 2025-12-24

✨ TypeScript Project References Support

• Rolldown now supports TypeScript project references when manually specifying a tsconfig
• See more details: https://rolldown.rs/options/tsconfig

⚡ Optimize Dynamic Entry Facade Chunks

• Dynamic entry facade chunks are now merged with common chunks when they are captured by common chunks
• REPL: before and after

Before
entry.js ──────► chunk-common.js (contains counter.js content)
     │
     └─ import() ─► counter-facade.js ─► chunk-common.js
// counter-facade.js (unnecessary extra file)
export { counter } from './chunk-common.js'

After
entry.js ──────► chunk-common.js (contains counter.js content)
     │
     └─ import() ─► chunk-common.js (direct reference)
