 const reveal = need(' reveal').
const application = reveal().

app.get('/', (req, res) => > {
res.send(' Hi, Globe!').
} ).

app.listen( 3000, () => > {
console.log(' Web server operating on port 3000').
} ).

In this instance, we initially import the Express.js component as well as produce a brand-new circumstances of the application making use of the reveal() feature.

Following, we specify a path trainer for the origin link making use of the app.get() technique. This technique takes 2 debates: the link pattern as well as a callback feature that is called when an obtain demand is made to that link.

Inside the callback feature, we call the res.send() technique to send out an action to the customer with the message “Hi, Globe!”.

Ultimately, we begin the web server by calling the app.listen() technique, which pays attention on port 3000 as well as logs a message to the console when the web server is begun.

This is simply a straightforward instance, as well as Express.js can be utilized to construct far more complicated internet applications as well as APIs. Yet it shows the standard framework as well as phrase structure of an Express.js web server.
