How to Add Functionality to Your HTML Forms with Express
When building web applications using NodeJS and Express, one common challenge developers face is integrating form submissions with backend functionality. If you've rendered a form but aren’t sure how to process its data, you’re not alone. This guide will walk you through the steps for adding functionality to the HTML you render in Express.
Understanding the Problem
You might have a scenario where you’ve successfully set up a form in your HTML, but processing the data when the form is submitted seems daunting. You've likely rendered the form but now want the ability to grab the data entered into the form and write it to a local file or handle it in some way.
The confusion often lies in the separation of client-side and server-side code, as well as how to handle static assets in Express.
Solution Overview
Step 1: Setting Up Your Environment
First, ensure your Express server is set up correctly. Here’s an example of how to initialize it:

Step 3: Parsing Form Data in Express
To handle the data submitted from the form, you will need to create an Express route that listens for POST requests. This is how you can set it up:

Step 4: Understanding Client vs. Server Code
The main distinction to understand here is:
Client-Side Code: This includes HTML, CSS, and JavaScript that runs in the user’s browser. You can use different methods to execute JavaScript on the client-side:
Embedded: Directly within an HTML file.
Inline: Using event handlers directly in HTML tags.
Server-Side Code: This runs on the server and deals with processing and responding to client requests. In our case, it’s where you write logic to handle form submission.
Conclusion
Integrating form functionality in an Express application involves rendering the HTML form correctly and ensuring the server can process the form submissions. By setting up proper routes and understanding the difference between client and server code, you can efficiently handle user input and perform actions like saving data or responding with status messages.
Now, you’re ready to take the next step in your NodeJS and Express journey. Happy coding!
