# tsx

6 Hacker News commenters recommended tsx and 3 criticized it, November 2025 to November 2026. It was recommended in 5 of 13 months.

**Verdict:** Runs TypeScript files in Node.js, valued for static typing and type checking. One critic reports mangled source maps that complicate debugging.

## Why people recommend it

- Static typing and type safety (4 comments): "It works nicely for these things because it already supports typed parameters and can be treated as a a raw AST without JS engine." ([source](https://news.ycombinator.com/item?id=47681080)) "You get full support for static typing and IDE code intelligence. That's huge and pretty much unique to TSX."
