Write Cloudflare Workers in 100% Rust via WebAssembly

Project mention: Python Cloudflare Workers | news.ycombinator.com | 2024-04-02

- The speed of the Python interpreter running in WebAssembly
Today, Python cold starts are slower than cold starts for a JavaScript Worker of equivalent size. A basic "Hello World" Worker written in JavaScript has a near zero cold start time, while a Python Worker has a cold start under 1 second.
That's because we still need to load Pyodide into your Worker on-demand when a request comes in. The blog post describes what we're working on to reduce this — making Pyodide already available upfront.
Once a Python Worker has gone through a cold start though, the differences are more on the margins — maybe a handful milliseconds, depending on what happens during the request.
- There is a slight cost (think — microseconds not milliseconds) to crossing the "bridge" between JavaScript and WebAssembly — for example, by performing I/O or async operations. This difference tends to be minimal — generally something measured in microseconds not milliseconds. People with performance sensitive Workers already write them in Rust https://github.com/cloudflare/workers-rs, which also relies on bridging between JavaScript and WebAssembly.
- The Python interpreter that Pyodide provides, that runs in WebAssembly, isn't as fast as the years and years of optimization that have gone into making JavaScript fast in V8. But it's still relatively early days for Pyodide, compared to the JS engine in V8 — there are parts of its code where we think there are big perf gains to be had. We're looking forward to upstreaming performance improvements, and there are WebAssembly proposals that help here too.

🚀 Develop and run serverless applications on WebAssembly

Project mention: Node on Web. Use Nodejs freely in your browser with Linux infrastructure. | /r/node | 2023-07-03

"Wasm Workers Server (wws) is an open source tool to develop and run serverless applications server on top of WebAssembly. The applications are composed by multiple modules called workers. Each of these tiny modules is in charge of replying to a specific HTTP endpoint in your application." Wasm Workers Server, "JavaScript Workers based on JavaScript work out of the box with Wasm Workers Server. The server integrates a JavaScript interpreter compiled into a WebAssembly module. Currently, the interpreter we support is quickjs and we are working on adding new ones." JavaScript
