Getting Started

A template for kick starting a Cloudflare worker project using workers-rs.

This template is designed for compiling Rust to WebAssembly and publishing the resulting worker to Cloudflare's edge infrastructure.

Usage

This template starts you off with a src/lib.rs file, acting as an entrypoint for requests hitting your Worker. Feel free to add more code in this file, or create Rust modules anywhere else for this project to use.

With wrangler, you can build, test, and deploy your Worker with the following commands:

# compiles your project to WebAssembly and will warn of any issues
wrangler build 

# run your Worker in an ideal development workflow (with a local server, file watcher & more)
wrangler dev

# deploy your Worker globally to the Cloudflare network (update your wrangler.toml file for configuration)
wrangler publish

WebAssembly

workers-rs (the Rust SDK for Cloudflare Workers used in this template) is meant to be executed as compiled WebAssembly, and as such so must all the code you write and depend upon. All crates and modules used in Rust-based Workers projects have to compile to the wasm32-unknown-unknown triple.

Read more about this on the workers-rs project README.

Issues

If you have any problems with the worker crate, please open an issue on the upstream project issue tracker on the workers-rs repository.
