Bubble and Xano Part 2: Single Detail View and Logout

Welcome to Xano, the no-code platform that empowers you to build and deploy backend services for web and mobile applications without writing a single line of code. In this step-by-step guide, we'll explore how to create a secure and dynamic application using Xano's visual interface and Bubble, a popular no-code platform for building web applications.

Part 1: Setting up Authentication and Fetching User-Specific Data

In the first part of this tutorial, we covered how to set up authentication using Xano's authentication engine and retrieve user-specific data from the backend. Here's a quick recap:

1. Authenticate Users with Xano: We integrated Xano's authentication engine with the Bubble front-end, storing the authentication token in the current user's data to keep track of the user's session.

2. Fetch User-Specific Data: We passed the authentication token to an authenticated endpoint in Xano, ensuring that users could only access data that belonged to them in the list view.

Part 2: Building a Detailed View and Implementing Logout

Now, let's take our application to the next level by creating a detailed view for individual items and adding a logout feature.

Step 1: Create a Detailed View

1. In your Bubble application, navigate to the list view page.
2. Double-click on one of the list items to start editing a new workflow.
3. When the list item is clicked, add a new action for navigation.
4. Select "Go to a page" and choose a new page (e.g., "Additional Info").
5. Send the item's ID as data to the new page by selecting "Current cell > My Restaurant ID" (or the appropriate field name) under "Data to send."

Now, let's set up the backend in Xano to fetch the detailed item information:

1. In Xano, create a new endpoint or use an existing one that retrieves a single item based on the provided ID.
2. Mark the endpoint as "Authentication Required."
3. Add a database request to fetch the authenticated user's information.
4. Add a precondition to ensure that the requested item belongs to the authenticated user (e.g., user.id === item.userId).

Back in Bubble, set up the API call to fetch the detailed item information:

1. Go to the "Additional Info" page and create a new group to hold the item details.
2. Set the group's data source to the API endpoint you created in Xano.
3. Insert the authentication token from the current user's data as a header.
4. Insert the item ID from the page URL as a path parameter.
5. Add dynamic data elements within the group to display the item's details (e.g., name, description, favorite dish).

Step 2: Implement Logout

To add a logout feature to your application, follow these steps:

1. On the "Additional Info" page (or any other page where you want the logout button), drag a new button onto the page.
2. Double-click the button to start editing a new workflow.
3. When the button is clicked, navigate to the "Account" section and make changes to the current user's data.
4. Clear the "Auth Token" field, effectively logging out the user by forgetting the authentication token.
5. Navigate back to the index page (or any other page you prefer) after logout.

That's it! You've now created a detailed view for individual items and implemented a logout feature in your Xano and Bubble application.
