Day 2: Creating a Signup Page with Express.js – Building the Foundation for User Registration

#backend #authentication #express

Despite a busy schedule as a Customer Engineer, I found time to explore the process of creating a signup page using Express.js. Here’s a step by step breakdown of the process:

Explanation of Steps

Create an Express App: Start by initializing a new Express.js application.

Create a Port for the Server: Define a port where your server will listen for requests.

Accept Body Data (Middleware): Middleware functions are crucial in Express.js to handle and process requests before they reach your route handlers. Use middleware like express.json() to handle incoming JSON or URL-encoded data.

Have HTML Pages for Signup Form: Design HTML pages to serve as the signup form interface. These pages will be served by your Express app.
Name the API Endpoint as /api/v1/signup: Define the signup API endpoint in your routes. This is where users will submit their signup information.

Check if User Already Exists: Implement logic to verify if the user is already registered in the database.

Validation of Input Data: Validate the data submitted by the user, ensuring it meets the required criteria. Here's an example of the validators:

Use Bcrypt to Encrypt the Password: Utilize the Bcrypt library to hash the user's password for secure storage.

Save User Data to Database: If validation passes, save the user's data in the database.

If Error Occurs, Send an Alert: Handle errors gracefully by sending an alert or error message. For example:

Redirect to Login Page or Dashboard: Upon successful signup, redirect the user to the login page or directly to the dashboard.
