Hello World Rust Boilerplate
A template for creating Cloudflare Workers using Rust and WebAssembly with the workers-rs SDK.
What is Hello World Rust Boilerplate?
rustwasm-worker-template is a starter template for building Cloudflare Workers using Rust and WebAssembly. It provides a configured project structure that compiles Rust code to WebAssembly for execution on Cloudflare's edge network, allowing developers to write serverless functions in Rust instead of JavaScript.
Rust developers who want to build Cloudflare Workers, and JavaScript developers looking to leverage Rust's performance and safety for edge computing applications.
This template offers a production-ready starting point with the workers-rs SDK already configured, eliminating setup complexity and enabling immediate development of Rust-based Workers with WebAssembly compilation.
Overview
A template for kick starting a Cloudflare Worker project using workers-rs. Write your Cloudflare Worker entirely in Rust!
Use Cases
Best For
- Building high-performance Cloudflare Workers in Rust
- Creating serverless functions with Rust's memory safety guarantees
- Developing edge computing applications with WebAssembly
- Migrating existing Rust applications to Cloudflare Workers
- Learning how to use Rust with Cloudflare's edge platform
- Creating type-safe alternatives to JavaScript-based Workers
Not Ideal For
- Projects requiring rapid prototyping with minimal compilation overhead
- Teams heavily dependent on JavaScript libraries or npm ecosystem integration
- Simple edge functions where JavaScript Workers provide sufficient performance and faster iteration
Pros & Cons
Pros
Leverages Rust's memory safety and efficiency for high-performance serverless functions, as emphasized in the GitHub description for edge computing applications.
Built on the official Cloudflare SDK, providing a configured setup that eliminates complexity, with commands for building and deploying via Wrangler, as detailed in the README.
Includes commands like `wrangler dev` for local development and `wrangler publish` for global deployment, offering an integrated toolchain for efficient development and testing.
Compiles Rust to WebAssembly for execution on Cloudflare's edge network, enabling portable and optimized code, as stated in the README for leveraging edge infrastructure.
Cons
All dependencies must compile to `wasm32-unknown-unknown`, restricting the use of many Rust crates not designed for WebAssembly, a limitation highlighted in the README.
Rust compilation adds overhead compared to JavaScript, slowing down the edit-test-debug cycle and making rapid prototyping less efficient.
The Rust ecosystem for Cloudflare Workers is less mature than JavaScript, with fewer third-party libraries, examples, and community resources available.
