Cloudflare and VoidZero, in collaboration with Max Schwenk of Owner.com, have introduced 'tsrs', a Rust port of the TypeScript compiler. This initiative aims to enhance performance and memory efficiency, achieving benchmarks of up to 8x faster and using approximately 70% less memory than TypeScript 7.0. The project is incubated within the Oxc JavaScript compiler toolchain and maintains close collaboration with the TypeScript team to ensure compatibility. The tsrs package is available for experimental use via npm, targeting the main branch of TypeScript. The developers emphasize that tsrs is not a fork but a faithful port, aiming for 100% conformance with TypeScript's design and direction. Users can provide feedback on performance and memory usage through an experimental browser playground.
