How to Enable HTTP/2.0 in Node.Js

Written by Rahul K. | December 23, 2015

Node-http2 is a node module which provides client and server implementation of HTTP/2 protocol for nodejs application. This node API is very similar to node https module with extended support for HTTP/2.

Install Node.Js

You may skip this step if you have already installed node.js on your system. If you don’t have node.js on your system, use following commands to install it.

$ sudo apt-get install python-software-properties python g++ make
$ curl -sL https://deb.nodesource.com/setup_5.x | sudo -E bash -
$ sudo apt-get update
$ sudo apt-get install nodejs

Or you can also upgrade Node.js via npm.

Install Node-HTTP2 Module

node-http2 module is available under default npm library. So just execute following command to install it for your application.

$ npm install http2

Create Sample Node Server

Let’s create a sample node server with http/2 support. First create a self signed ssl certificate or get a valid SSL from authorized ssl providers.

$ openssl req -x509 -nodes -newkey rsa:2048 -keyout example.com.key -out example.com.crt

Now create http2-server.js file with following content.

var fs = require('fs');
var options = {
  key: fs.readFileSync('./example.com.key'),
  cert: fs.readFileSync('./example.com.crt')
};

require('http2').createServer(options, function(request, response) {
  response.end('Welcome HTTP/2.0');
  console.log(&quot;Server listening on: http://localhost:8000&quot;);
}).listen(8000);

var fs = require('fs');

var options = {

key: fs.readFileSync('./example.com.key'),

cert: fs.readFileSync('./example.com.crt')

};

require('http2').createServer(options, function(request, response) {

response.end('Welcome HTTP/2.0');

console.log("Server listening on: http://localhost:8000");

}).listen(8000);

Start Node Server

Let’s start the node.js server using following command. It will start a web server on port 8000 port on your system.

$ node http2-server.js

and access localhost on port 8000 like below.
