WebAssembly Today

Access local files from web browsers via WASI 👏

The WebAssembly Systems Interface (WASI) allows WebAssembly apps to access the file system. So, now you can access local files from a browser-based app.

wasmbin: a self-generating WebAssembly parser & serializer 👊

The wasmbin library gives Rust developers the ability to manipulate WASM code directly in Rust source code as macros. Very impressive.

Towards sockets and networking in WebAssembly and WASI ✍️

WASI gives WASM programs access to operating standard libraries, except for networking and sockets! This article proposes a way to add socket support for WASI and describes a minimal implementation in AssemblyScript and Rust.

on "binary security of webassembly" 🗣

This article provides a critical response to the paper “Everything Old is New Again: Binary Security of WebAssembly”, which we covered in past issues. Worth reading.

File Converter, a free and unlimited file converter 💻

File Converter converts media files, including images and videos, from one type to another, right inside your browser. Behind the scene, it uses the FFMPEG library, which is compiled to WebAssembly, to perform the conversion in the browser.

WASM Sunray, a ray-tracing tool 👁

(The image is generated from WASM Sunray, and I added the watermark via serverless wasm.)

WASM Sunray is written in Rust and compiled to WebAssembly to run in the browser. It uses thread.js to run the WASM rendering functions in a worker thread.

Vugu: a modern UI library for Go+WebAssembly (experimental) 😎

Have you ever wanted to write a Web UI without JS? Try Vugu, a VUE-js inspired library in GO, and compiled to WebAssembly. Write Web UI in Go and run it in the browser.

Tutorial: How to Use Rust, WebAssembly, JavaScript, and PubSub+ to Run Native Apps in Your Browser 🤜

PubSub+ is a JavaScript framework that can tie together the browser JS host with WebAssembly programs written in Rust.

Rusty News

The fastest and most energy-efficient languages ⚡️

C is the fastest and most energy-efficient. Rust wins second place ahead of even C++. In comparison, Go is 3x, JavaScript is 6x, and Python is 70x slower and wasteful.

Valve's Proton 5.13, now uses Rust 🦀

Proton 5.13 is released. The exciting news is that Proton is now using Rust, in production, as part of media-converter!
