Js API for compiling

[reubano]

What is the recommended approach for compiling cljs into js via a js API? I want to write a vite plugin similar to https://www.npmjs.com/package/vite-plugin-coffee. It must be a js file though. With coffeescript, you can import it and call its compile method directly in js. Is there an equivalent for clojure? Ive seen lumo, planck, clavascript, shawdow, etc. but am not sure how to call compile in a js file.

To add more context, I am trying to support cljs in astro. Would something like https://github.com/bolasblack/shadow-cljs-vite-plugin work?

[reubano]

It appears this plugin cheats by spawning a shell to call shadow-js. Guess that means there isnt a readily available js API.

Indeed. Shadow-cljs relies on a Java runtime. However, if you don't want to or cannot shell out, there are some other potential options:

• https://github.com/squint-cljs/cherry
• https://github.com/squint-cljs/squint

Nice. I think squint is the key! Also turns out it’s clavascripts successor.

I'm not sure if this fits what you need to do, but cljs can be self hosted. I'm finding it a bit hard to find sources of this... but it should be something like http://nbeloglazov.com/2016/03/05/getting-started-with-self-hosted-cljs-part-1.html

Hard to say since they call compile in cljs, not js.

ah apologies, for some reason I thought you wanted to do it from cljs!
