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.

By following these steps and understanding the underlying code, you can create a secure and efficient signup page using Express.js. Stay tuned as I continue to explore more topics in my #100DaysOfMiva challenge.
Next up, I’ll be diving into authentication with a database to further enhance the security and functionality of this signup page.
