With Shopify functions, a RUST deliverable is run on WASM with JS handling the front end. This is something Crystal would be perfect for, not only is RUST a lot more difficult to program with, but Shopify is a heavy Ruby development shop & Crystal is just as fast as RUST in these scenarios. Shopify…

Also very relevant: [image] WebAssembly potential use cases Community Serverless functions with WebAssembly seem to have a bright future. We are implementing a WebAssembly platform here at Shopify, you already pointed out Cloudflare, and there are others such as Fermyon . …

I consider this not always the tech issue. Maybe manas consider contribute Crystal to community, as rust get reborn after Mozilla contribute rust to https://foundation.rust-lang.org

Yes, if there was this level of funding it would make a lot of sense. Of course, the development experience vs RUST for Shopify Ruby devs coming from standard Ruby would be immense. If you hearing this Shopify, you should be a member ;) [Screen Shot 2022-06-23 at 5.04.14 pm]

Crystal is just as fast as RUST in these scenarios. Would be interesting to see that proved out. The system is in developer preview and we have a documented spec for adding new languages if folks want to give it a shot. We also have a tool for testing the performance/memory/module size.

See the “Roadmap to WebAssembly support” GitHub issue for some explanations of difficulties and possible solutions in adding a WASM target for Crystal. Before reading it, I thought that garbage collection would be a huge issue, but apparently the GC can be compiled to WASM as well. Related, I think…

Maybe it’s better to say “Would be faster to write” & “Easier code to understand” instead :sweat_smile:

From what I could see Shopify functions are short-lived, i.e. they start, read input, write output, and exit everytime. This is a good design for WebAssembly and this means that a GC won’t even need to run, most likely. Unless you are doing something really memory intensive and above 1 second or so.…
