Learn how to connect your frontend form to a Node.js backend using Express and the Fetch API.
In this step-by-step tutorial, I walk through the complete workflow: capturing form submissions, validating input, sending JSON requests to an Express route (/api/ask), and displaying the server’s response dynamically in the browser.

This tutorial covers:

Setting up a Node.js + Express backend

Creating an API endpoint (POST /api/ask)

Sending requests from the frontend with the Fetch API

Handling JSON responses and displaying them on the page

Error handling for invalid input, server errors, and network failures

Whether you're a beginner or brushing up on full-stack basics, this video gives you a practical example of how modern web apps communicate between the client and server.
