Build Google Spanner-Connected Apps in Bubble

Bubble is a no-code platform that simplifies the process of developing and launching apps and businesses. When coupled with CData Connect AI, you gain effortless no-code access to Google Spanner data for streamlined app development. This article guides you through the integration process from Bubble to Google Spanner using CData Connect AI.

CData Connect AI provides a pure cloud-to-cloud OData interface for Google Spanner data that allows you to integrate from Bubble to Google Spanner data in real time.

Connect to Google Spanner from Bubble

To work with Google Spanner data from Bubble, we need to connect to Google Spanner from Connect AI, provide user access to the connection, and create a Workspace for the Google Spanner data.

Connect to Google Spanner from Connect AI

CData Connect AI uses a straightforward, point-and-click interface to connect to data sources.

1. Log into Connect AI, click Sources, and then click Add Connection
👁 Adding a Connection

2. Select "Google Spanner" from the Add Connection panel
👁 Selecting a data source

3. Google Spanner uses OAuth to authenticate. Click "Sign in" to authenticate with Google Spanner. 👁 Authenticating with OAuth (Salesforce is shown).
   
4. Navigate to the Permissions tab in the Add Google Spanner Connection page and update the User-based permissions. 👁 Updating permissions
   

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create. 👁 Creating a new PAT
   
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Configure Google Spanner Endpoints for Bubble

After connecting to Google Spanner, create a workspace for your desired table(s).

1. Navigate to the Workspaces page and click Add to create a new Workspace (or select an existing workspace). 👁 The Workspaces page.
   👁 Adding a new Workspace.
   
2. Click Add to add new assets to the Workspace.
3. Select the Google Spanner connection (e.g. GoogleSpanner1) and click Next. 👁 Selecting an Asset (Salesforce is shown).
   
4. Select the table(s) you wish to work with and click Confirm. 👁 Selecting Tables (Salesforce is shown).
   
5. Make note of the OData Service URL for your workspace, e.g. https://cloud.cdata.com/api/odata/{workspace_name}

With the connection, PAT, and Workspace configured, you are ready to connect to Google Spanner data from Bubble.

Build a Google Spanner-Connected App

With OData endpoints added to Connect AI, you can build an app in Bubble with live access to Google Spanner data.

Configure the Bubble API Connector

To start, Configure the API Connector for accessing CData Connect AI from Bubble.

1. In your app, click the Plugins tab and click Add plugins
2. Search for "API Connector" and click Install 👁 Installing the API Connector plugin
   
3. After installation, click the "Add another API" button and configure the API:
   • Name the API
   • Set Authentication to "HTTP Basic Auth"
   • Set Username to a Connect AI user (e.g. [email protected])
   • Set Password to the PAT for the user
   • Expand the API Call, select the "GET" command and set the URL to a Workspace endpoint you previously configured (e.g. https://cloud.cdata.com/api/odata/{workspace_name}/Customer)
   👁 Configuring the API Call
   
4. Click the "Initialize call" button to adjust data types in the response (as needed) 👁 Initializing the call
   
5. After making any necessary changes, click "Save" 👁 Saving the data types
   

Configure the App UI

With the API Connector configure, you are ready to retrieve Google Spanner data in your Bubble app. In this article, we request the data with a UI component that can display an Excel-like table.

1. On the Plugin tab, install the "Excel-like HandsonTable" 👁 Adding the Excel-like HandsonTable plugin
   
2. On the Design tab, add an "Excel Table" to the workspace 👁 Adding an Excel Table to the app
   
3. In the Excel Table, in Data source, select "Get data from an external API"
4. Set Type of content to "API Call value"
5. Set Data source to "CData Connect AI - API Call's value" (or equivalent) 👁 Binding the Excel Table to the API Call
   
6. Click "Preview" to ensure the data was retrieved from Google Spanner. 👁 Previewing the app
   

At this point, you can develop applications with live access to Google Spanner data without needing to know the complexities of the back-end API.

Live Access to Google Spanner Data from Cloud Applications

Now you have a direct connection to live Google Spanner data from Bubble. You can create more Google Spanner-connected apps — all without writing any code or replicating Google Spanner data.
