Build HCL Domino-Connected Web Apps with Axios and CData Connect Cloud



Use CData Connect Cloud to connect to live HCL Domino data and build HCL Domino-connected web apps with Axios.

Axios is a JavaScript library that allows developers to make HTTP requests to servers from a web browser or Node.js. When paired with CData Connect Cloud, you get access to live HCL Domino data for your web apps. This article shows how to connect to HCL Domino and build web apps in Axios with access to live HCL Domino data.

Connect to HCL Domino from Axios

To work with HCL Domino in Axios, we need to connect to HCL Domino from Connect Cloud, provide user access to the connection, and create OData endpoints for the HCL Domino data.

(Optional) Add a New Connect Cloud User

As needed, create Users to connect to HCL Domino 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 HCL Domino 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 "HCL Domino" from the Add Connection panel
  3. Enter the necessary authentication properties to connect to HCL Domino.

    Connecting to Domino

    To connect to Domino data, set the following properties:

    • URL: The host name or IP of the server hosting the Domino database. Include the port of the server hosting the Domino database. For example: http://sampleserver:1234/
    • DatabaseScope: The name of a scope in the Domino Web UI. The driver exposes forms and views for the schema governed by the specified scope. In the Domino Admin UI, select the Scopes menu in the sidebar. Set this property to the name of an existing scope.

    Authenticating with Domino

    Domino supports authenticating via login credentials or an Azure Active Directory OAuth application:

    Login Credentials

    To authenticate with login credentials, set the following properties:

    • AuthScheme: Set this to "OAuthPassword"
    • User: The username of the authenticating Domino user
    • Password: The password associated with the authenticating Domino user

    The driver uses the login credentials to automatically perform an OAuth token exchange.

    AzureAD

    This authentication method uses Azure Active Directory as an IdP to obtain a JWT token. You need to create a custom OAuth application in Azure Active Directory and configure it as an IdP. To do so, follow the instructions in the Help documentation. Then set the following properties:

    • AuthScheme: Set this to "AzureAD"
    • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
    • OAuthClientId: The Client ID obtained when setting up the custom OAuth application.
    • OAuthClientSecret: The Client secret obtained when setting up the custom OAuth application.
    • CallbackURL: The redirect URI defined when you registered your app. For example: https://localhost:33333
    • AzureTenant: The Microsoft Online tenant being used to access data. Supply either a value in the form companyname.microsoft.com or the tenant ID.

      The tenant ID is the same as the directory ID shown in the Azure Portal's Azure Active Directory > Properties page.

  4. Click Create & Test
  5. Navigate to the Permissions tab in the Add HCL Domino Connection page and update the User-based permissions.

Note the CData Connect Cloud SQL API Endpoint(s)

CData Connect Cloud contains API endpoints that allow you to submit SQL queries to HCL Domino through common web requests. To work with HCL Domino data in Axios web apps, you will use the query endpoint.

Query Endpoint

https://cloud.cdata.com/api/query

With the connection and Workspace configured, you are ready to connect to HCL Domino data from Axios.

Connect to HCL Domino Data in Axios Workflows

To establish a connection from Axios to CData Connect Cloud using the OData protocol, follow these steps.

  1. Create a project directory for your web app. For example: ~/connect_cloud/
  2. Open a terminal, navigate the the project directory and initialize a node project using the command: npm init -y
  3. Install the Axios dependency in the project using the following command: npm install axios
  4. In your project directory, create a file called server.js that contains the following code. Provide your CData Connect Cloud username (e.g. [email protected]) and PAT (the PAT you created in the prerequisites). You must also provide a query for your data, such as SELECT * FROM Domino1.SCHEMA.ByName.

    server.js code

    const axios = require('axios') const user = '[email protected]' const pat = '***********************************'; //Your API endpoint const url = 'https://cloud.cdata.com/api/query'; //Your data to be sent in the POST request const data = { "query":"SELECT * FROM Domino1.SCHEMA.ByName" }; axios.post(url, data, { auth: { username: user, password: pat } }) .then(response => { const rows = response.data.results[0].rows; const schema = response.data.results[0].schema; //Create an array of column names const columnNames = schema.map(col => col.columnName); //Loop through each row and log the column name with its value rows.forEach(row => { const rowObject = {}; row.forEach((value, index) => { const columnName = columnNames[index]; rowObject[columnName] = value; }); console.log(rowObject); }) }) .catch(error => { console.error('Error:', error); });
  5. In the terminal, execute the following command to run the server: node server.js The query results will appear: { ID: 1, VALUE: -2 } { ID: 2, VALUE: 1 } { ID: 11, VALUE: null } { ID: 3, VALUE: 2 } { ID: 4, VALUE: 5 } ...
