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:
- 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.
- 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
- In your Bubble application, navigate to the list view page.
- Double-click on one of the list items to start editing a new workflow.
- When the list item is clicked, add a new action for navigation.
- Select "Go to a page" and choose a new page (e.g., "Additional Info").
- 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:
- In Xano, create a new endpoint or use an existing one that retrieves a single item based on the provided ID.
- Mark the endpoint as "Authentication Required."
- Add a database request to fetch the authenticated user's information.
- 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:
- Go to the "Additional Info" page and create a new group to hold the item details.
- Set the group's data source to the API endpoint you created in Xano.
- Insert the authentication token from the current user's data as a header.
- Insert the item ID from the page URL as a path parameter.
- 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:
- On the "Additional Info" page (or any other page where you want the logout button), drag a new button onto the page.
- Double-click the button to start editing a new workflow.
- When the button is clicked, navigate to the "Account" section and make changes to the current user's data.
- Clear the "Auth Token" field, effectively logging out the user by forgetting the authentication token.
- 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.
