Lightweight library for building Rust-WASM services on Cloudflare Workers.

The goal of this library is to make it easy to build fast and lightweight HTTP-based services in WASM, hosted on Cloudflare Workers. To keep things fast and lightweight, there is a strong preference for significant new capabilities to added as compile-time features or separate libraries.

Features

• Fully async
• Request & response bodies can be text, json, or binary
• Non-blocking structured logging
• Deferred tasks that run after response is returned to client

Add-ons

• CORS handling and OAuth2

Getting started

To start a new project,

wrangler generate -t rust PROJECT \
    https://github.com/stevelr/rustwasm-service-template

where PROJECT is your project name.

rustwasm-service-template contains some relevant sample code, as well as instructions for setting up of Cloudflare and (optionally) Coralogix logging service.

Updates (v0.3)

• Changes to support add-ons. See CHANGELOG for recent changes including breaking api changes to Handler.handle and Runnable.run functions.
