Create IBM Cloud Object Storage-Connected Applications in Appsmith
Appsmith is an open-source internal tool builder that allows teams to quickly and easily build a UI to help improve their business operations. When combined with CData Connect AI, you gain immediate access to IBM Cloud Object Storage data for business applications. This article outlines the process of connecting to IBM Cloud Object Storage using Connect AI and creating a basic application from IBM Cloud Object Storage data within Appsmith.
CData Connect AI offers a pure SQL Server, cloud-to-cloud interface for IBM Cloud Object Storage, enabling the creation of business applications directly from live IBM Cloud Object Storage data within Appsmith, all without the need for data replication to a native database. As you build applications, Appsmith generates SQL queries to gather data. With its inherent optimized data processing capabilities, CData Connect AI efficiently channels all supported SQL operations, including filters and JOINs, directly to IBM Cloud Object Storage. This leverages server-side processing to swiftly deliver the requested IBM Cloud Object Storage data.
Configure IBM Cloud Object Storage Connectivity for Appsmith
Connectivity to IBM Cloud Object Storage from Appsmith is made possible through CData Connect AI. To work with IBM Cloud Object Storage data from Appsmith, we start by creating and configuring a IBM Cloud Object Storage connection.
- Log into Connect AI, click Sources, and then click Add Connection
- Select "IBM Cloud Object Storage" from the Add Connection panel
-
Enter the necessary authentication properties to connect to IBM Cloud Object Storage.
Register a New Instance of Cloud Object Storage
If you do not already have Cloud Object Storage in your IBM Cloud account, follow the procedure below to install an instance of SQL Query in your account:
- Log in to your IBM Cloud account.
- Navigate to the page, choose a name for your instance and click Create. You will be redirected to the instance of Cloud Object Storage you just created.
Connecting using OAuth Authentication
There are certain connection properties you need to set before you can connect. You can obtain these as follows:
API Key
To connect with IBM Cloud Object Storage, you need an API Key. You can obtain this as follows:
- Log in to your IBM Cloud account.
- Navigate to the Platform API Keys page.
- On the middle-right corner click "Create an IBM Cloud API Key" to create a new API Key.
- In the pop-up window, specify the API Key name and click "Create". Note the API Key as you can never access it again from the dashboard.
Cloud Object Storage CRN
If you have multiple accounts, specify the CloudObjectStorageCRN explicitly. To find the appropriate value, you can:
- Query the Services view. This will list your IBM Cloud Object Storage instances along with the CRN for each.
- Locate the CRN directly in IBM Cloud. To do so, navigate to your IBM Cloud Dashboard. In the Resource List, Under Storage, select your Cloud Object Storage resource to get its CRN.
Connecting to Data
You can now set the following to connect to data:
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
- ApiKey: Set this to your API key which was noted during setup.
- CloudObjectStorageCRN (Optional): Set this to the cloud object storage CRN you want to work with. While the connector attempts to retrieve this automatically, specifying this explicitly is recommended if you have more than Cloud Object Storage account.
When you connect, the connector completes the OAuth process.
- Extracts the access token and authenticates requests.
- Saves OAuth values in OAuthSettingsLocation to be persisted across connections.
- Click Save & Test
-
Navigate to the Permissions tab in the Add IBM Cloud Object Storage Connection page and update the User-based 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.
- Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
- On the Settings page, go to the Access Tokens section and click Create PAT.
-
Give the PAT a name and click Create.
- The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
With the connection configured and a PAT generated, we are ready to connect to IBM Cloud Object Storage data from Appsmith.
Create an Appsmith Application from live IBM Cloud Object Storage Data
To establish a connection from Appsmith to the CData Connect AI Virtual SQL Server, follow these steps:
Connect to IBM Cloud Object Storage in Appsmith
- Log in to your Appsmith instance and create a new application.
-
In the new application, open the Data page and select Bring your data.
-
On this page, you can search for Microsoft SQL Server and select it as your data source.
-
Enter a name for the new data source and then enter the following connection settings:
- Host address: tds.cdata.com
- Port: 14333
- Database name: enter the Connection Name of the CData Connect AI data source you want to connect to (for example, IBMCloudObjectStorage1).
- Username: enter your CData Connect AI username. This is displayed in the top-right corner of the CData Connect AI interface. For example, [email protected].
- Password: enter the PAT you previously generated.
- Click Test configuration to confirm a successful connection, then click Save to save the datasource.
Create a new query
With a connection configured to a datasource, we can add a SQL query to actually retrieve data from the data source.
-
On the screen with the new data source, click New Query.
-
This opens the Query Editor to enter a SQL query to select data. To assist with specifying a SQL query, use the Explorer of CData Connect AI to preview the SQL queries and the data you want to retrieve.
-
After creating the SQL query, return to the Query Editor in Appsmith and enter the SQL query, then click Run.
- Once the query successfully runs, all that remains is to set up the Page to display the data retrieved.
Display IBM Cloud Object Storage data
-
Open the UI tab and click New UI element.
-
Choose a new UI element to grab, then drag and place the element on the page.
-
Click Connect data on the new UI element, then select the query previously created.
-
With the data connected, it is then displayed in the UI element.
Deploy the application
With the IBM Cloud Object Storage data connected to the UI elements in the application, we can deploy the Application. To do this, click Deploy in the top-right corner of Appsmith, then the application is opened in a separate window displaying the IBM Cloud Object Storage data.
