To enable
HTTP/2
in
Koa.js
, you need to use a server that supports
HTTP/2
, such as Node.js with the
http2
module. The
http2
module is part of the
Node.js
standard library and provides support for the
HTTP/2
protocol.
Here's a step-by-step guide on how to enable
HTTP/2
in
Koa.js
using Node.js with the
http2
module:
1. Install Required Dependencies : Ensure you have
Node.js
installed on your machine. Additionally, make sure your project has the necessary dependencies, including koa and
http2
.
npm install koa http2?
2. Create an HTTP/2 Server with Koa : Use the
http2
module to create an
HTTP/2 server and integrate it with your Koa.js application.
const Koa = require('koa');
const http2 = require('http2');
const app = new Koa();
// Your Koa application setup goes here
// Create an HTTP/2 server with the Koa app as the callback
const server = http2.createSecureServer({
key: /* Your SSL key path */,
cert: /* Your SSL certificate path */,
}, app.callback());
// Start the server on the desired port (e.g., 3000)
const port = 3000;
server.listen(port, () => {
console.log(`HTTP/2 server is running on https://localhost:${port}`);
});?
Replace
/* Your SSL key path */
and
/* Your SSL certificate path */
with the paths to your SSL key and certificate files. For development purposes, you can generate self-signed certificates or use tools like
mkcert
.
3. Configure SSL for Local Development : For local development, you can generate self-signed certificates using a tool like
mkcert
. Install
mkcert
globally and generate a certificate for your local domain.
# Install mkcert
brew install mkcert
# Generate a certificate for localhost
mkcert -install
mkcert -key-file key.pem -cert-file cert.pem localhost?
Update the
SSL key
and certificate paths in your Koa app accordingly.
4. Verify HTTP/2 Support :Verify that your server is using
HTTP/2
by checking the protocol in your browser's developer tools or using online tools like
