Problem

Hi, I would like to know if Express 5.0 will have support for http2: https://github.com/molnarg/node-http2 I was reading a bit and I noticed that exist a problem with http2 module: https://github.com/molnarg/node-http2/issues/100 I have tested in local and the problem continues: https://github.com/jabrena/CloudFoundryLab/blob/master/Node_HelloWorld_http2_express/index.js It this issue in the roadmap? Does exist another alternative to run a express application with http2? Many thanks in advance. Juan Antonio

Implement HTTP/2 Support in Express Application

Medium Risk

The current version of Express (5.0) does not natively support HTTP/2 due to dependencies on the underlying Node.js HTTP module, which has limitations and issues when used with the 'node-http2' module. This results in incompatibility and errors when attempting to run an Express application over HTTP/2.

Awaiting Verification

Be the first to verify this fix

  1. 1

    Install Required Packages

    To enable HTTP/2 support, install the 'http2' module and 'express' if not already installed. This allows you to create an HTTP/2 server that can handle requests.

    bash
    npm install express http2
  2. 2

    Create an HTTP/2 Server

    Use the 'http2' module to create a server that wraps your Express application. This will allow you to serve your Express app over HTTP/2.

    javascript
    const http2 = require('http2');
const express = require('express');
const app = express();

const server = http2.createServer(app);

server.on('stream', (stream, headers) => {
  app.handle(stream, headers);
});

server.listen(3000);
  3. 3

    Update Express Middleware for HTTP/2

    Ensure that any middleware used in your Express application is compatible with HTTP/2. Some middleware may need adjustments to properly handle streams.

    javascript
    // Example middleware adjustment
app.use((req, res, next) => {
  res.stream = res; // Adjust response object for HTTP/2
  next();
});
  4. 4

    Test Your Application

    Run your application and test it using an HTTP/2 client or browser that supports HTTP/2. Check for any errors in the console and ensure that the application responds correctly.

    bash
    curl -I --http2 https://localhost:3000
  5. 5

    Monitor Performance and Logs

    After deploying the application, monitor performance metrics and logs to ensure that HTTP/2 is functioning as expected and to identify any potential issues.

    javascript
    // Use logging middleware to monitor requests
app.use((req, res, next) => {
  console.log(`Request: ${req.url}`);
  next();
});

Validation

Confirm that the application is accessible via HTTP/2 by using a compatible client or browser. Check the response headers for 'HTTP/2' and ensure that there are no errors in the console. Additionally, monitor logs for any unexpected behavior.
