AssemblyScript

Actions Status npm npm@nightly

AssemblyScript compiles a strict subset of TypeScript (basically JavaScript with types) to WebAssembly using Binaryen. It generates lean and mean WebAssembly modules while being just an npm install away.

Check out the documentation or try it out in WebAssembly Studio!

Motivation

You are now able to write WebAssembly, without learning a new language, and harness all these benefits WebAssembly might offer you. I think that is kind of powerful. [...] It [AssemblyScript] is absolutely usable, and very enjoyable! - Surma, WebAssembly for Web Developers (Google I/O ’19) (May 8th, 2019)

AssemblyScript was frictionless. Not only does it allow you to use TypeScript to write WebAssembly, [...] it also produces glue-free WebAssembly modules that are very small with decent performance. – Surma, Replacing a hot path in your app's JavaScript with WebAssembly (Feb 16, 2019)

Perhaps the fundamental issue [to get a small .wasm file] is that JavaScript is the only language for which the Web runtime is a perfect fit. Close relatives that were designed to compile to it, like TypeScript, can be very efficient as well. But languages like C, C++, Rust, and so forth were not originally designed for that purpose. – Alon Zakai, Small WebAssembly Binaries with Rust + Emscripten (Apr 18, 2018)

JavaScript's heyday as the only browser language is over, but most web developers are used to writing JavaScript, and learning a new syntax just to get access to WebAssembly is not (always) ideal. If only there was something in to bridge the gap… – Jani Tarvainen, TypeScript is the bridge between JavaScript and WebAssembly (Feb 20, 2018)

I do think [compiling TypeScript into WASM] is tremendously useful. It allows JavaScript developers to create WASM modules without having to learn C. – Colin Eberhardt, Exploring different approaches to building WebAssembly modules (Oct 17, 2017)
