Use the CData API Server to create an OData API on top of GraphQL data and visualize live GraphQL data in Infragistics Reveal.

Reveal is a data visualization solution provided by Infragistics and can be paired with the CData API Server to build dynamic dashboards from live GraphQL data. The CData API Server generates an OData API for GraphQL, which is natively consumable in Reveal. In this article, we walk through connecting to GraphQL in API Server and connecting to the API Server from Infragistics Reveal to create a simple dashboard.

Connect to GraphQL from API Server

CData API Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Open API Server and click Settings -> Connection -> Add Connection πŸ‘ Adding a connection
  2. Select "GraphQL" πŸ‘ Selecting a Connector (Salesforce is shown).
  3. Enter the necessary authentication properties to connect to GraphQL.

    You must specify the URL of the GraphQL service. The driver supports two types of authentication:

    • Set AuthScheme to Basic. You must specify the User and Password of the GraphQL service.
    • Take a look at the OAuth section in the Help documentation for detailed instructions.
    πŸ‘ Configuring a connection (Salesforce is shown).

Add GraphQL Resource Definitions in API Server

After connecting to GraphQL, create Resources, which represent API endpoints for GraphQL data.

  1. Click Settings -> Resources -> Add Resource πŸ‘ Adding a new resource
  2. Select the GraphQL connection πŸ‘ Selecting a connection (Salesforce is shown)
  3. Select the table you wish to retrieve and click Next πŸ‘ Selecting a Table (Salesforce is shown)
  4. (Optional) Edit the resource to select specific fields and more
  5. Save the settings

Add an API Server User

Create a User to connect to GraphQL from Reveal through API Server.

  1. Click Settings -> Users
  2. Click Add
  3. Configure a User with access to the GraphQL Connection and Resource(s) πŸ‘ Creating a new user
πŸ‘ API Server users

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple different domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in Settings -> Server.

  • Enable cross-origin resource sharing (CORS): ON
  • Allow all domains without '*': ON
  • Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
  • Access-Control-Allow-Headers: Authorization

Save the changes to the settings.

Create a Dashboard in Reveal

With the API Server configured, we can visualize GraphQL data in Reveal.

  1. Log into Reveal and click Dashboards -> New πŸ‘ Adding a new dashboard
  2. Click Data Source -> OData Feed πŸ‘ Adding a new OData data source
  3. Specify the API Server API endpoint URL, for example: https://serverurl/api.rsc πŸ‘ Configuring the OData URL
  4. Select Generic Credentials and specify the API Server username and authentication token πŸ‘ Configuring the credentials
  5. Select the entity you wish to visualize πŸ‘ Selecting an entity to visualize (Salesforce is shown.)
  6. Select fields and choose a chart type πŸ‘ Visualizing data in Reveal (Salesforce is shown.)
