Express is ripe to be replaced. It has the weirdest syntax I've ever seen and is basically designed around call back hell.

In Koa, handlers don't respond to the request. Instead, they update a representation of the response and return a promise. The response bubbles up to the top-level where the `res.send()` is done.
This way you have real middleware. You can post-process the response or do something else entirely after the downstream has run.
const middleware = async (ctx, next) => {
console.log('request going down')
await next()
console.log('request coming up')
}
