Express

Make sure you have the express package installed in your project. If you don't have it installed, you can install it using the following command:

npm install express

How to use the Snippet

Write the snippet in your new file expsrv:

server.js

import express from 'express';

const app = express();

app.use(express.json());

const PORT = process.env.PORT || 3000;

app.get('/', (req, res) => {
  res.send('Hello World!');
});

app.use((req, res) => {
  res.status(404).send('404 Not Found');
});

app.listen(PORT, () => {
  console.log('Server is running on port: ', PORT);
});

In the snippet above, we created a simple Express.js server that listens on port 3000. The server has two routes:

1. The root route / that returns a Hello World! message.
2. A 404 route that returns a 404 Not Found message for all other routes.
