This repository is a proof of concept about the process of calling WASM code generated in Rust from ClojureScript through JavaScript interoperability.
To run this project you need Rust and Clojure.
I am using clojure 1.10.2, rustup 1.26.0 (stable channel) and rustc 1.70.0.
This project includes a makefile that will automatically:
- install some tools with specific versions
- build wasm
- copy wasm files to web site project
- build web site
- serve web site
You can run it executing:
make
I didn't found a way to serve the web site using ClojureScript. That means, that we cannot use the REPL. If you try to do that, you will find the following problem:
TypeError: WebAssembly: Response has unsupported MIME type 'text/html; charset=utf-8' expected 'application/wasm'
and
Uncaught CompileError: wasm validation error: at offset 4: failed to match magic number
If you search for the first error message you will find https://clojure.atlassian.net/browse/CLJS-3387. The problem seems to be solved, but Will Cohen complains that is still not working.
If you want to check that error. You have to move out, wasm and index.html from clojurescript-addition/public to clojurescript-addition/. Then run clojure -M -m cljs.main -c addition.core --repl.
Probably, you are going to build a web site using ClojureScript with a build tool. If you are going to use shadow cljs. I highly recommend that you take a look into a demo using wasm with clojurescript from the shadow cljs creator.
