Httpolyglot

Part of HTTP Toolkit: powerful tools for building, testing & debugging HTTP(S)

A module for serving HTTP, HTTPS and HTTP/2 connections, all over the same port.

Forked from the original httpolyglot to fix various issues required for HTTP Toolkit, including:

• Support for HTTP/2
• Fixing tlsClientError: https://github.com/mscdex/httpolyglot/pull/11
• Include initially sniffed bytes aren't lost in subsequent clientError events (https://github.com/mscdex/httpolyglot/issues/13)
• Dropping support for very old versions of Node (and thereby simplifying the code somewhat)
• Converting to TypeScript
• Event subscription support (subscribe to server.on(x, ...) to hear about x from all internal servers - HTTP/2, HTTP/1, TLS and net)

Requirements

• node.js -- v12.0.0 or newer

Install

npm install @httptoolkit/httpolyglot

Examples

• Simple usage:

const httpolyglot = require('@httptoolkit/httpolyglot');
const fs = require('fs');

httpolyglot.createServer({
  key: fs.readFileSync('server.key'),
  cert: fs.readFileSync('server.crt')
}, function(req, res) {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.end((req.socket.encrypted ? 'HTTPS' : 'HTTP') + ' Connection!');
}).listen(9000, 'localhost', function() {
  console.log('httpolyglot server listening on port 9000');
  // visit http://localhost:9000 and https://localhost:9000 in your browser ...
});

• Simple redirect of all http connections to https:

const httpolyglot = require('@httptoolkit/httpolyglot');
const fs = require('fs');

httpolyglot.createServer({
  key: fs.readFileSync('server.key'),
  cert: fs.readFileSync('server.crt')
}, function(req, res) {
  if (!req.socket.encrypted) {
    res.writeHead(301, { 'Location': 'https://localhost:9000' });
    return res.end();
  }
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.end('Welcome, HTTPS user!');
}).listen(9000, 'localhost', function() {
  console.log('httpolyglot server listening on port 9000');
  // visit http://localhost:9000 and https://localhost:9000 in your browser ...
});

API

Exports

• Server - A class similar to https.Server (except instances have setTimeout() from http.Server).

• createServer(< object >tlsConfig[, < function >requestListener]) - Server - Creates and returns a new Server instance.

How it Works

TLS and HTTP connections are easy to distinguish based on the first byte sent by clients trying to connect. See this comment for more information.
