User Authentication in Mongoose: Admins and Users in One Collection
In web development, managing user authentication effectively is crucial for the security of your application. This post addresses a common scenario many developers face: how to authenticate both admins and regular users when they are stored in a single MongoDB collection using Mongoose, Node.js, and Express. If you find yourself stuck trying to authenticate a user while maintaining access for your admin, you’re in the right place!
Understanding the Problem
You've likely defined a schema where both admins and users are nested in a single collection. It works great for admin access, but accessing user details can be troublesome because user data resides within an array, making it not as straightforward as it seems.
Take a look at the provided schema:

With this setup, when an admin logs in, they can easily access their information, but when a user tries to authenticate, they might face issues since user data is bundled inside an array.
The Solution
To solve the authentication issue for regular users while ensuring that admins can log in seamlessly, you’ll need a smart querying approach combined with password hashing for security. Here’s how you can set it up:
Step 1: Query the User's Data
You will need to modify your database query to correctly access the user's information. Here’s how to do that using an aggregation query:

This query checks for a user with a given email and filters the user array to return only the matching document.
Step 2: Handling the Response
The result from the aggregation query will include matched user data. It’ll look something like this:

Step 3: Comparing Passwords
Once you have the user's information, you can compare the passwords using bcrypt. Here's an example that demonstrates how to do this properly:

Conclusion
By applying the above aggregation approach, you can effectively manage authentication for both admins and users in a single collection. Remember, always hash passwords for security—bcrypt is a reliable library for this purpose.
If you find this process daunting, remember: practice makes perfect! Ensure you test your authentication flow thoroughly after implementing these changes.
By following these steps, you have set yourself on a path to smoothly handle user authentication in your Node.js application with Mongoose.
