Medley

Medley is a fast and modern web framework for Node.js. It fully supports both async/await and callbacks and is compatible with Node 6 or greater. It's design incorporates concepts found in Express, Koa, hapi, and Fastify. Most importantly, Medley aims to provide an API that is forward-compatible with future versions that will take full advantage of Node's HTTP/2 module.

Usage

Install:

npm install @medley/medley
# or
yarn add @medley/medley

Create a web server:

const medley = require('@medley/medley')
const app = medley()

app.get('/', (req, res) => {
  res.send('Hello World')
})

app.listen(3000)

Forward-Compatibility with the http2 Module

HTTP/2 is the future of the web. It is faster than HTTP/1.x and comes with new, speed-boosting features such as server push. The Node.js http2 module has a very different API from the http/https modules, but it also provides a compatibility API. Medley currently uses the compatibility API (to support both HTTP/1.x and HTTP/2), but Medley's API is designed such that when Medley upgrades to the full http2 API, application code built on Medley should not need to change. Medley's goal is to insulate application code from this transition (as much as possible) so that code written now that won't require massive rewrites in the future.
