With that, we have created a simple node server to serve static content as well a simple API to return JSON data.

We have also added an else statement to handle all other requests where we simply return a message to the browser that the request is not supported.

createServer ( serverHandler ) // callback function definition function serverHandler ( req, res ) =>. Server.js const http = require ( 'http' ) const path = require ( 'path' ) const fs = require ( 'fs' ) const PORT = 3000 const hostname = 'localhost' // createServer is the http method used to create a web server that takes a callback.

Now we will create a node server that will serve our index.html file when a request is sent to /. Index.html Demo Coming from the Root Step 3: Add our server code to serve the static assets Create a directory called public at the root of your project.Īdd a file named index.html with the following content.
