Panics in Rust Workers were historically fatal, poisoning the entire instance. By collaborating upstream on the wasm‑bindgen project, Rust Workers now support resilient critical error recovery, including panic unwinding using WebAssembly Exception Handling.
As a proof of concept, we built a Matrix homeserver to Cloudflare Workers — delivering encrypted messaging at the edge with automatic post-quantum cryptography.
Cloudflare Workers now support FinalizationRegistry, but just because you can use it doesn’t mean you should.
Introducing Cloudflare Workers in Python, now in open beta! We've revamped our systems to support Python, from the runtime to deployment. Learn about Python Worker's lifecycle, dynamic linking, and memory snapshots in this post
Debugging Rust and Wasm with Cloudflare Workers involves a lot of the good old time-consuming and nerve-wracking printf'ing strategy. What if there’s a better way? This blog is about enabling and using Wasm core dumps and how you can easily debug Rust in Cloudflare Workers
Today Pages is excited to offer support for WebAssembly when writing a Pages Function
After the recent announcement regarding WASI support in Workers I decided to see what it would take to get code written in Zig to run as a Worker, and it turned out to be pretty trivial. This post documents the process I followed
Today, we are announcing experimental support for WASI (the WebAssembly System Interface) on Cloudflare Workers and support within wrangler2 to make it a joy to work with
Introducing the Cloudflare Workers Rust SDK: write your entire Worker in Rust, no JavaScript required.
Let's combine the power of Haskell and WebAssembly in a Cloudflare Worker!
Today, we're open sourcing and announcing wrangler, a CLI tool for building, previewing, and publishing Rust and WebAssembly Cloudflare Workers. If that sounds like some word salad to you, that's a reasonable reaction.
