stc VS cross

Wonder no more: https://github.com/dudykr/stc

Written in Rust by the (lead?) dev of SWC

SWC (speedy web compiler) compiles TS to JS

The analogy (by swc's author) would be https://github.com/dudykr/stc

I'm also hoping for STC https://stc.dudy.dev/ but I don't think it will be released any time soon.

MyPy and tsc on the other hand? Please make a Ruff for MyPy and hurry up and fund the author of SWC to develop STC. I'm tired of waiting several seconds after each :w for my quickcheck window to update.

And it would speed up the TypeScript Compiler.

My bet is:

TypeScript typechecker in Rust:

https://github.com/dudykr/stc

typescript(tsc) is the only one that does type checking.

bun, deno, esbuild, swc etc. can parse the syntax, but they chuck the TS (they probably don't even add it to the AST, but I haven't checked).

Keeping up with syntax is very doable. It doesn't change often, and updating the parser when it does isn't much work.

There are some past/ongoing projects[1][2] to create type checkers faster than tsc, but they aren't going to reach full parity and probably don't plan on keeping up with language features.

Well the checker is in progress.

To compile a program with musl on a glibc system you can use cross-rs!

I cross compile to Mac, bsd, windows, etc cross ... Works great for me with either docker or podman.

If docker is available for you, https://github.com/cross-rs/cross is another and reliable way to solve this kind of problem. I do use it regularly.

We are using https://github.com/cross-rs/cross.

There is some built-in support in rustc for cross-compiling, but getting the build to actually work can be tricky due to the need for an appropriate linker. Instead, we’re going to use the Cross crate, which used to be maintained by the Rust Embedded Working Group Tools group.

I have used cross before to cross compile from Linux to other Linux. It has a section on it's wiki about this. Maybe that could be of help.

You can use cross to build your application and copy the artifacts into an alpine armv7 container. It would also build faster due to using cross compilation rather than QEMU.

Looks like cross is the easiest way to get something cross-compiled but its Mac support is blocked behind building your own build image. Even that repo says that it might be broken.

Bonus: if you’re working with Rust and doing a lot of cross platform stuff, check out cross. It runs QEMU in docker so you can run tests on a bunch of different emulated targets easily- literally a one line setup, it’s kind of magical.

It's also not as naturally cross-compilable as Go, though that's partly a side-effect of not accepting being a semi-closed ecosystem to achieve that and cross exists as a stop-gap while things like cargo-zigbuild explore less drastic options.
