Hey, I was trying to do this same thing for a TypeScript project I was bootstrapping. Digging around the issue tracker, I recall the maintainer stating that this is currently not in the scope of esbuild, and that swc[0] might be better suited for this. Personally, I wrote a crude JS script using the esbuild transform API + node-watch to compile .ts files and copy files/folders during development. This is all very recent, so I can't ensure that it's bulletproof quite yet. [0] https://swc.rs/ https://swc.rs/
