Node.js: How do you implement a custom HTTP/2 server in Node.js?

1const http2 = require("http2");
2const fs = require("fs");
3
4const server = http2.createSecureServer({
5    key: fs.readFileSync("server.key"),
6    cert: fs.readFileSync("server.cert"),
7});
8
9server.on("stream", (stream, headers) => {
10    const path = headers[":path"];
11
12    // Server Push
13    if (path === "/index.html") {
14        stream.pushStream({ ":path": "/style.css" }, (err, pushStream) => {
15            pushStream.respond({ ":status": 200 });
16            pushStream.end(fs.readFileSync("style.css"));
17        });
18    }
19
20    // Regular response
21    stream.respond({ ":status": 200, "content-type": "text/html" });
22    stream.end("<h1>Hello HTTP/2</h1>");
23});
24
25server.listen(3000);

1const client = http2.connect("https://localhost:3000");
2
3const req = client.request({ ":path": "/data" });
4req.on("response", (headers) => {
5    console.log("Status:", headers[":status"]);
6});
7let data = "";
8req.on("data", (chunk) => data += chunk);
9req.on("end", () => console.log(data));
10req.end();
