Middleware Example

HTTPure does not have a use function like systems such as express.js, but you can still use middlewares! This example illustrates how purely functional middlewares in HTTPure work. It includes an example middleware that logs to the console at the beginning and end of each request, one that injects a header into the response, and one that handles requests to a given path.

To run the example server, run:

nix-shell --run 'example Middleware'

Or, without nix:

spago -x test.dhall run --main Examples.Middleware.Main
