Overview

Setting up user registration and login in Xano means creating endpoints to handle user data securely. Begin with designing a database schema to store details like usernames, passwords, and more. The next step is to configure API endpoints for both registration and login, while also integrating security measures such as password hashing and token generation. It's important to establish validation rules and error handling too, ensuring a smooth authentication process. This setup allows effective management of user accounts, delivering a seamless experience for all users.

How to set up user registration and login flows in Xano?

Step 1: Set Up Your Database

  1. Head over to the Database section in Xano.
  2. Create a new table and call it users.
  3. Add these fields to the users table:
    • id (Integer, Primary Key, Auto Increment)
    • email (String)
    • password_hash (String)
    • created_at (DateTime, default to current timestamp)

Step 2: Configure User Registration Endpoint

  1. Go to the API section and create a new API group named auth.

  2. Create a new POST endpoint and name it register.

  3. In the Input tab, set up the request body like this:

    • email (String, required)
    • password (String, required)
  4. In the Function tab, add these actions:

    • Validation: Check if a user with the given email already exists.
    • Data Transformation: Hash the password using a secure hashing algorithm.
    • Database Operation: Insert a new user record in the users table with the provided email and hashed password.
    • Response: Send a success message or an error message if the email is already in use.

Step 3: Configure User Login Endpoint

  1. In the auth API group, create a new POST endpoint and name it login.

  2. In the Input tab, set up the request body like this:

    • email (String, required)
    • password (String, required)
  3. In the Function tab, add these actions:

    • Database Operation: Retrieve the user record by email.
    • Validation: Check if the retrieved user exists and if the provided password matches the stored password hash.
    • Token Generation: Generate an authentication token (JWT) if the login is successful.
    • Response: Send the authentication token or an error message if the login fails.

Step 4: Secure Your Endpoints

  1. In the API section, edit the endpoints that should be restricted to authenticated users.
  2. Click on the Security tab.
  3. Enable security for the endpoints by checking the box and selecting the token type (JWT) defined in the previous step.

Step 5: Handle Token Validation Middleware

  1. In the auth API group, create a new POST endpoint and name it validate_token.
  2. In the Input tab, define the request header as Authorization (String, required).
  3. In the Function tab, add these actions:
  • Token Validation: Validate the provided token.
  • Response: Send user details or an error message if the token is invalid.

Step 6: Connect Endpoints to Frontend

  1. Set up HTTP requests in the frontend application to call the register and login endpoints.
  2. Store the authentication token received after a successful login in local storage or cookies.
  3. Include the token in the Authorization header for any restricted API calls.
