Write Your Own Express.js From Scratch

Want to become an Express expert? There's no better way to really grok a framework than to write your own clone from scratch.

In 15 concise pages, this tutorial walks you through how to write a simplified clone of Express called Espresso. Espresso supports:

- Route handlers, like `app.get()` and `app.post()`

- Express-compatible middleware, like `app.use(require('cors')())`

- Express 4.0 style subrouters

As a bonus, Espresso also supports async functions, unlike Express.
