Build Presto-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 Cloud, you gain effortless no-code access to Presto data for streamlined app development. This article guides you through the integration process from Bubble to Presto using CData Connect Cloud.

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

Connect to Presto from Bubble

To work with Presto data from Bubble, we need to connect to Presto from Connect Cloud, provide user access to the connection, and create OData endpoints for the Presto data.

(Optional) Add a New Connect Cloud User

As needed, create Users to connect to Presto through Connect Cloud.

1. Navigate to the Users page and click Invite Users
2. Enter the new user's email address and click Send to invite the user
3. You can review and edit users from the Users page

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Connect to Presto from Connect Cloud

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

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Presto" from the Add Connection panel
3. Enter the necessary authentication properties to connect to Presto.

   Set the Server and Port connection properties to connect, in addition to any authentication properties that may be required.

   To enable TLS/SSL, set UseSSL to true.

   Authenticating with LDAP

   In order to authenticate with LDAP, set the following connection properties:

   • AuthScheme: Set this to LDAP.
   • User: The username being authenticated with in LDAP.
   • Password: The password associated with the User you are authenticating against LDAP with.

   Authenticating with Kerberos

   In order to authenticate with KERBEROS, set the following connection properties:

   • AuthScheme: Set this to KERBEROS.
   • KerberosKDC: The Kerberos Key Distribution Center (KDC) service used to authenticate the user.
   • KerberosRealm: The Kerberos Realm used to authenticate the user with.
   • KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.
   • KerberosKeytabFile: The Keytab file containing your pairs of Kerberos principals and encrypted keys.
   • User: The user who is authenticating to Kerberos.
   • Password: The password used to authenticate to Kerberos.
4. Click Create & Test
5. Navigate to the Permissions tab in the Add Presto Connection page and update the User-based permissions.

Configure Presto Endpoints for Bubble

After connecting to Presto, create a workspace and virtual dataset for your desired table(s).

1. Navigate to the Virtual Datasets page and click Add to create a new Workspace (or select an existing workspace).
2. Click Add to add new assets to the Workspace.
3. Select the Presto connection (e.g. Presto1) and click Next.
4. Select the table(s) you wish to work with and click Confirm.
5. Make note of the OData Service URL for your workspace, e.g. https://cloud.cdata.com/api/odata/{workspace_name}

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

Build a Presto-Connected App

With OData endpoints added to Connect Cloud, you can build an app in Bubble with live access to Presto data.

Configure the Bubble API Connector

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

1. In your app, click the Plugins tab and click Add plugins
2. Search for "API Connector" and click Install
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 Cloud user (e.g. user@mydomain.com)
   • Set Password to the PAT for the above 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)
4. Click the "Initialize call" button to adjust data types in the response (as needed)
5. After making any necessary changes, click "Save"

Configure the App UI

With the API Connector configure, you are ready to retrieve Presto 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"
2. On the Design tab, add an "Excel Table" to the workspace
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 Cloud - API Call's value" (or equivalent)
6. Click "Preview" to ensure the data was retrieved from Presto.

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

Live Access to Presto Data from Cloud Applications

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