Fastest, baddest and most experimental HTTP/2 framework for Node.js

Installation

Install from npm, note that funl requires Node 8.4.0 and above with the --expose-http2 for 8.x.x versions.

$ npm install funl --save

Write a funl Http/2 server

const Funl = require('funl');
const app = new Funl({
  cert: "", // SSL Cert
  key: "" // SSL Key
});

app.on('/', async (stream) => {
  stream.end("Hello World!");
});

app.listen(8080);

A short bit on Multiplexing and Stream Objet

Http/2 has many differences from Http/1.1, perhaps the most notable difference is multiplexing. For this reason routing in funl is not mapped to a request but rather to a substream. This interface allows you to push handles from a specific path without redefining them.

Write a middleware

Middlewares are special handles in funl that allow for interception of streams pre and post processing/flight. You can add a middleware preflight executing before all handles are consumed and postflight after the handles are done. A stream may or may not be open when postflight handles are called.

app.preflight(async (stream) => {
  console.log({ method: stream.method });
});

app.postflight(async (stream) => {
  console.log({ headers: stream.headers });
});

Middlewares can be called via internal requests (push) and don't map into an actual client-side request.
