Building Your First Bubble Application: A Step-by-Step Guide

Let's walk through the process of building a simple application using Bubble. For this example, we'll create a basic "To-Do List" application.

1. Setting Up Your Project:

• Create a New Application: Navigate to Bubble's website and create a new account or log in to your existing one. Start a new application by clicking the "Create an app" button. Give your application a name and choose a plan that suits your needs.
• Choose a Template or Start from Scratch: Bubble offers a variety of templates that can serve as a starting point for your application. For this tutorial, we'll start with a blank page to gain a better understanding of the platform's fundamentals.

2. Designing the User Interface (UI):

• Add Input Fields: Drag and drop an "Input" element onto the canvas. This will allow users to enter their to-do items. Label this input field clearly (e.g., "New To-Do").
• Add a Button: Drag and drop a "Button" element onto the canvas. This button will trigger the action of adding the to-do item to the list. Label the button "Add To-Do."
• Add a Repeating Group: Drag and drop a "Repeating Group" element onto the canvas. This element will dynamically display the list of to-do items.

3. Configuring the Data Structure:

• Create a Data Type: Go to the "Data" tab in the Bubble editor. Create a new data type called "ToDo."
• Add a Field: Within the "ToDo" data type, add a field called "Task" of type "text." This field will store the text of each to-do item.
• Add a Field: Add another field within the "ToDo" data type called "Completed" of type "yes/no". This field will track if the task is completed.

4. Defining the Workflow:

• Create a Workflow for the "Add To-Do" Button: Select the "Add To-Do" button and click "Start/Edit Workflow."
• Create a New Thing: In the workflow editor, add an action to "Create a new thing."
• Set the Data Type: Set the type of thing to create to "ToDo."
• Set the Field Values: In the "Set fields" section, set the "Task" field to the value of the "New To-Do" input field (e.g., Input New To-Do's value). Set the "Completed" field to "no."
• Reset Input: Add an action to "Reset relevant inputs" to clear the input field after adding the to-do item.

5. Configuring the Repeating Group:

• Set the Data Source: Select the "Repeating Group" element. In the "Data source" field, search for all "ToDo" entries (e.g., Do a search for ToDos).
• Add a Text Element: Drag and drop a "Text" element inside the repeating group. This text element will display the task for each to-do item.
• Set the Text Content: Set the content of the text element to the current cell's "ToDo's Task" (e.g., Current cell's ToDo's Task).
• Add a Checkbox: Drag and drop a "Checkbox" element inside the repeating group.
• Create a Workflow for the Checkbox: Select the Checkbox element and click "Start/Edit Workflow."
  • Make changes to a thing: In the workflow editor, add an action to "Make changes to a thing."
  • Thing to change: Set the "Thing to change" to Current cell's ToDo.
  • Set the Field Values: In the "Set fields" section, set the "Completed" field to the value of the checkbox.

6. Testing Your Application:

• Preview Your Application: Click the "Preview" button in the Bubble editor to test your application in a new browser tab.
• Add To-Do Items: Enter text into the input field and click the "Add To-Do" button. Verify that the to-do items are added to the repeating group.
• Check To-Do Items: Click the checkbox to mark a task as completed. Verify that the checkmark shows on the task.

This simple To-Do List application provides a foundational understanding of Bubble's core concepts. You can expand upon this base by adding features like editing to-do items, deleting to-do items, and filtering the list based on completion status.

Building Two Interconnected Bubble Applications

Now, let's explore the more advanced scenario of building two separate but interconnected Bubble applications. This approach can be beneficial when you want to isolate specific functionalities, manage complex projects more effectively, or provide different user experiences based on specific roles.

Scenario: Building a Customer Portal and an Admin Dashboard

Imagine you're building a SaaS product that requires both a customer-facing portal and an administrative dashboard for managing users, content, and settings. Creating two separate Bubble applications for these purposes offers several advantages:

• Improved Performance: By separating the applications, you can reduce the load on each individual application, leading to faster loading times and a more responsive user experience.
• Enhanced Security: Separating the applications allows you to implement stricter security measures for the administrative dashboard, protecting sensitive data from unauthorized access.
• Simplified Development: Dividing the project into smaller, more manageable applications can simplify the development process and make it easier to maintain and update the codebase.
• Customized User Experiences: You can tailor the user interface and functionality of each application to meet the specific needs of its users, providing a more intuitive and efficient experience.

Strategies for Interconnecting Two Bubble Applications:

There are several ways to connect two Bubble applications, depending on the level of integration required:

• API Integration: This is the most robust and flexible method for connecting two Bubble applications. It involves creating an API (Application Programming Interface) in one application that allows the other application to access and manipulate its data.
  • Exposing Data via the API: In the first application (e.g., the main application), you can use Bubble's API Connector to expose specific data types and workflows as endpoints.
  • Connecting to the API: In the second application (e.g., the admin dashboard), you can use Bubble's API Connector to connect to the API endpoints exposed by the first application. This allows you to retrieve data, create new data, update existing data, and trigger workflows in the first application.
• Data Sharing via External Databases: You can use an external database (e.g., Firebase, Xano) to store data that needs to be shared between the two applications. Both applications can then connect to the external database and access the same data. This is useful for data that needs to be synchronized in real-time or for handling large datasets.
• URL Parameters: For simpler scenarios, you can pass data between the two applications using URL parameters. This involves encoding data into the URL when navigating from one application to the other. The receiving application can then extract the data from the URL parameters. This method is suitable for passing small amounts of data, such as user IDs or product IDs.
• Plugins: Some plugins offer built-in functionality for connecting to other Bubble applications or external services. These plugins can simplify the integration process and provide pre-built components for common tasks.

Example: Connecting the Customer Portal and Admin Dashboard via API Integration

Let's illustrate the API integration approach with a simplified example of connecting the Customer Portal and Admin Dashboard.

1. Setting up the API in the Customer Portal Application:

• Enable the Data API: In the Customer Portal application, go to "Settings" -> "API." Enable the "Data API" and select the data types that you want to expose to the Admin Dashboard (e.g., "User," "Product").
• Generate an API Token: Generate a new API token and save it securely. This token will be used by the Admin Dashboard to authenticate with the Customer Portal API.
• Enable Workflow API: Enable the "Workflow API" and create an endpoint to allow the Admin Dashboard to manage users.

2. Connecting to the API in the Admin Dashboard Application:

• Install the API Connector Plugin: In the Admin Dashboard application, install the "API Connector" plugin.
• Create a New API Connection: Create a new API connection in the API Connector plugin.
• Configure the API Connection:
  • API Name: Give the API connection a descriptive name (e.g., "Customer Portal API").
  • Authentication: Choose "Private key in header" as the authentication method.
  • Header Key: Enter "Authorization" as the header key.
  • Header Value: Enter "Bearer " followed by the API token you generated in the Customer Portal application (e.g., Bearer YOUR_API_TOKEN).
• Define API Calls: Define API calls for each endpoint that you want to use in the Admin Dashboard. For example, you can create API calls to:
  • Get a list of users: This API call would retrieve a list of all users from the Customer Portal application.
  • Get a specific user: This API call would retrieve the details of a specific user based on their ID.
  • Create a new user: This API call would create a new user in the Customer Portal application.
  • Update an existing user: This API call would update the details of an existing user.
  • Delete a user: This API call would delete a user from the Customer Portal application.
• Configure the API Calls: For each API call, specify the HTTP method (e.g., GET, POST, PUT, DELETE), the URL of the API endpoint, and any required parameters.

3. Using the API Calls in the Admin Dashboard:

• Retrieve Data: Use the API calls to retrieve data from the Customer Portal application and display it in the Admin Dashboard. For example, you can display a list of users in a repeating group, retrieve the details of a specific user when they are selected in the list, and display the user's information in input fields.
• Manipulate Data: Use the API calls to manipulate data in the Customer Portal application. For example, you can create new users, update existing users, and delete users using buttons and workflows in the Admin Dashboard.

This example demonstrates how to use API integration to connect two Bubble applications. You can extend this approach to connect any number of applications and build complex workflows that span across multiple applications.
