Thats not how one usually work. Whats the point in running tsc (the official transpiler) on each save? Plus, you are using an LSP client right? right??

Im a user of esbuild, and its so fast it can recompile on each save (see esbuild `serve` option) and i wont notice anything locally. Theres also a watch mode, and production build with minify.

So i work locally without a typecheck for my builds, and let my LSP client do the type checking. When i bundle for prod i run an additional tsc for type checks before the bundle is produced. Takes a few secs more (as tsc is slow) but this is a nonissue.

I recompile on every save too, all with full typechecking in under a second. As I've suspected, this is probably because most people here work in bigcorp projects where there are so many thousands of files that you cant work like this anymore. It's not because it's actually better workflow wise, it's only better for you now because otherwise the compilation is too slow. Same as the situation that has developed with Rust.

I don't, and I think maybe you should reconsider your assumptions about literally every single person replying.

Your assumption (from your first comment) is that people only run bundling. That's not the case. People run bundling in parallel to type checking, rather than in series. You still get the type checking benefits without blocking your build on it and thus slowing down your dev process.

that was never my assumption

Did sound like it:

> why would anyone want only bundling

> most people here work in bigcorp projects where there are so many thousands of files that you cant work like this anymore

This is not a bigcorp thing. The Typescript compiler starts becoming annoyingly slow much earlier. I have a project that's one 2000-line TS file that already takes 1.5 seconds to compile. Not yet slow enough to be frustrating, but ridiculous for the amount of code.
