Cloudflare has open sourced wrangler, a CLI tool for building, previewing, and publishing Rust and WebAssembly Cloudflare Workers. The company aims to help build a better internet by leveraging its large global network of servers to run code as close as possible to end users, reducing latency associated with server-side logic or large client-side bundles. Wrangler is designed to enable developers to harness the power of WebAssembly on Workers and support various toolchains such as Emscripten (C, C++) and AssemblyScript (TypeScript). The open source release aims to broaden the community that has access at the early stages of this technology and gather valuable feedback from users.
