expressjsHow can I use Express.js to enable HTTP/2 support?
Express.js is a popular web application framework for Node.js that can be used to enable HTTP/2 support. To do so, you will need to use the spdy
module, which is included in the Express.js installation.
Here is an example of how to enable HTTP/2 support in Express.js:
const express = require('express');
const spdy = require('spdy');
const app = express();
spdy
.createServer({
key: fs.readFileSync('server.key'),
cert: fs.readFileSync('server.crt')
}, app)
.listen(3000, (error) => {
if (error) {
console.error(error);
return process.exit(1);
} else {
console.log('Listening on port: 3000.');
}
});
This code will create an HTTPS server on port 3000 using the server.key
and server.crt
files. It will also enable HTTP/2 support for the Express.js application.
Code explanation
const express = require('express')
- This imports the Express.js module.const spdy = require('spdy')
- This imports thespdy
module which is used to enable HTTP/2 support.const app = express()
- This creates an Express.js application.spdy.createServer()
- This creates an HTTPS server and enables HTTP/2 support.key: fs.readFileSync('server.key')
- This provides the server key which is used to create the HTTPS server.cert: fs.readFileSync('server.crt')
- This provides the server certificate which is used to create the HTTPS server.listen()
- This starts the server on the specified port.
