Simplify implementation of serverless WASM on Cloudflare Workers

Features

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

Getting started

To get started with a WASM service, use

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

where PROJECT is your project name.

Follow instructions in rustwasm-service-template for Cloudflare setup and (optional) Coralogix logging setup

Dependencies

This crate takes advantage of some recent updates in the popular reqwest (v0.10.9+) that make it possible to do outgoing http requests from a Cloudflare worker. It is now possible to write libraries using http clients that compile for both wasm targets and other non-wasm targets such as native windows/mac/linux, without any feature switches.
