24 alternatives to Write Language-agnostic functions with WebAssembly you can use

Hey y’all, we’re really excited to share that we’re launching a new free, open source tool called Scale. It’s a highly-performant WebAssembly function runtime that enables composable, language-agnostic software development. TL;DR - Scale allows you to write functions in any language, then use them in any other language. It’s pretty exciting. We currently support Go and Rust, but TypeScript is coming soon and support for a handful of other languages is already in the works. We’d love to hear any feedback you have, so let us know what you think!

Scale is a free, open source WebAssembly runtime that lets developers write functions in one programming language and use them in another. Currently supporting Go and Rust with TypeScript and additional languages in… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Write Language-agnostic functions with WebAssembly you can use launched in 2023; newer entries below may have overtaken it.

    As a personal project I wrote a really tiny Wat 2 Wasm compiler in Go. Mainly for demonstrative and educational purposes. It was tough: I didn't know anything about WebAssembly internals and I'm a newbie with Go... so I tried to document it as much as I could for anyone that would like to approach the quest in the future! It misses a lot of features (that will be gradually implemented). Any feedback is welcomed!! Demo: https://luna-demo.vercel.app

    Show HN: TinyWasm - A tiny WebAssembly Runtime written in Rust Hi HN! I'm excited to share TinyWasm (https://github.com/explodingcamera/tinywasm), a WebAssembly Interpreter I developed for my final university project. The main goal of this project was to deepen my understanding of WebAssembly and interpreter design. TinyWasm successfully passes all the official WebAssembly 1.0 tests and also includes features from future proposals such as like bulk memory operations. Initially more of a research project, TinyWasm focuses on simplicity and portability. It has minimal…

    Hey HN! I've been working on a book about WebAssembly over the last few months, and it's finally available at http://levelupwasm.com! Why a book on WebAssembly you ask? Well... WebAssembly is awesome (obviously ) but it's certainly not the easiest thing to learn. So I wrote this book as a practical intro to using WebAssembly in your web apps. I would appreciate any feedback!

    An implementation of a dynamic programming language in Rust. Includes: Parser/Compiler, REPL, Virtual Machine, Bytecode Disassembler This started out as a learning project to teach myself Rust. It has grown into a decently substantial piece of software and I've learned quite a bit in the process! Some neat things: + A garbage collector that can store dynamically sized types without any double-indirection (i.e. I have my own Box implementation with manual alloc/dealloc) + The smart pointer used to reference GCed data is a thin pointer. The ptr metadata needed for DSTs is stored in…

    No gc, No goroutines, Produces small binaries while using the unmodified official go toolchain, and comes with complete Web SDK (generated from w3c/webref). We are building `pcz` to provide a reimagination of Go the language, in an effort to make it suitable for all kinds of programming tasks, and currently you can use it to build efficient web applications in Go using the generated Web SDK (as shown with the live web demo[1]). The journey is just starting, any suggestions? or any critics? [1]: https://primecitizens.github.io/livedemos/10-plat-web/

    I've open sourced a JavaScript to WASM compiler. It's an experimental tool, but given the semantics I already implemented, I'm fairly certain I am able to eventually cover 100% of JavaScript spec. Any ideas, questions or critique welcomed! If you are interested in WASM, especially with new proposals like WASM GC or exception handling, it might be a good source of seeing these features in action - the project has a few thousand lines of hand written WAT so far.

    I've built many interpreters over the years, and Bolt represents my attempt at building the scripting language I always wanted. This is the first public release, 0.1.0! I've felt like most embedded languages have been moving towards safety and typing over years, with things like Python type hints, the explosive popularity of typescript, and even typing in Luau, which powers one of the largest scripted evironments in the world. Bolt attempts to harness this directly in the lagnauge rather than as a preprocessing step, and reap benefits in terms of both safety and performance. I intend to be…

    Hey all, I just wanted to share a project I've been working on for the past month. After years of heavy frameworks, I really like the idea of using htmx, but it’s a little too low level for me and needs a thin layer above it to facilitate things like components, better syntax with complex JS inside of an attribute, etc To try and solve this problem with a very minimal stack (golang + htmx) that I've been really enjoying, I'm building this project to cater to my needs and was thinking it would be useful for other developers.

    I spent the past 2 weeks making this toy programming language. I basically forked the Go scanner/parser, and changed the syntax to have functions return a single value. This enable proper Result/Option type to be used as well as propagating errors with an operator. I also wanted to have short "type inferred" anonymous functions to be able to use functions like Map/Reduce/Filter, without having to use 100 characters to specify the types.

    Hey HN, I’m sharing ts-chan, an NPM package providing Go-like concurrency primitives, including channels and select statements, for TypeScript and JavaScript, supporting Node.js, Deno, Bun, and browsers. This is something I've built to make implementing Go-style "control loops" feasible in JavaScript, but there are many possible applications. Highlights: - Features a FIFO processing Chan class and versatile Select class for concurrency control. - Supports buffered channel and channel close semantics very close to Go's. - TypeScript-first implementation. - Defines a simple "channel protocol"…
