express node js app code example
Example 1: express js server
const express = require('express');
const app = express();
const PORT = process.env.PORT || 3000;
app.get('/', (req, res) => {
res.send('<h1>Some HTML</h1>');
res.send('<p>Even more HTML</p>');
});
app.listen(PORT, () => console.log(`Server is listening on port ${PORT}`));
Example 2: node.js express
const express = require('express')
const app = express()
const port = 3000
app.get('/', (req, res) => res.send('Hello World!'))
app.listen(port, () => console.log(`Example app listening at http://localhost:${port}`))
Example 3: 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}/`);
})
Example 4: express nodejs
