Cloudflare and its acquired VoidZero announced that they are taking over the open-source project tsrs, a TypeScript compiler rewritten in Rust that has been merged into the Oxc toolchain. According to heise online, Cloudflare claims that with the same number of threads, tsrs's type checking is up to 8 times faster than TypeScript 7.0 and uses about 70% less memory; the project founder's own tests show 2.5 to 5 times faster with about one-third the memory. The current version 0.18 is still experimental, uses the Apache 2.0 license, and provides native binaries for macOS ARM and Linux, with no Windows version yet.
