Example 1: express and node
// Load HTTP module
const http = require("http");
const hostname = "127.0.0.1";
const port = 8000;
// Create HTTP server
const server = http.createServer((req, res) => {
// Set the response HTTP header with HTTP status and Content type
res.writeHead(200, {'Content-Type': 'text/plain'});
// Send the response body "Hello World"
res.end('Hello World\n');
});
// Prints a log once the server starts listening
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
})
