A simple URL shortener built with Spin

This is a simple URL shortener built with Spin, running as a WebAssembly module.

The only configuration needed is the source and destination to redirect to:

[[route]]
source = "/spin"
destination = "https://github.com/fermyon/spin"

[[route]]
source = "/hype"
destination = "https://www.fermyon.com/blog/how-to-think-about-wasm"

Running can be done from the root of the repository with Spin:

$ spin up --file spin.toml

Then, sending requests to routes configured in routes.toml returns the response pointing to the configured destination:

$ curl -i localhost:3000/spin
HTTP/1.1 308 Permanent Redirect
location: https://github.com/fermyon/spin
