Reveal is a data visualization solution provided by Infragistics and can be paired with the CData API Server to build dynamic dashboards from live Neo4J data. The CData API Server generates an OData API for Neo4J, which is natively consumable in Reveal. In this article, we walk through connecting to Neo4J in API Server and connecting to the API Server from Infragistics Reveal to create a simple dashboard.
Connect to Neo4J from API Server
CData API Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
- Open API Server and click Settings -> Connection -> Add Connection
π Adding a connection
- Select "Neo4J"
π Selecting a Connector (Salesforce is shown).
- Enter the necessary authentication properties to connect to Neo4J.
To connect to Neo4j, set the following connection properties:
- Server: The server hosting the Neo4j instance.
- Port: The port on which the Neo4j service is running. The provider connects to port 7474 by default.
- User: The username of the user using the Neo4j instance.
- Password: The password of the user using the Neo4j instance.

Add Neo4J Resource Definitions in API Server
After connecting to Neo4J, create Resources, which represent API endpoints for Neo4J data.
- Click Settings -> Resources -> Add Resource
π Adding a new resource
- Select the Neo4J connection
π Selecting a connection (Salesforce is shown)
- Select the table you wish to retrieve and click Next
π Selecting a Table (Salesforce is shown)
- (Optional) Edit the resource to select specific fields and more
- Save the settings
Add an API Server User
Create a User to connect to Neo4J from Reveal through API Server.
- Click Settings -> Users
- Click Add
- Configure a User with access to the Neo4J Connection and Resource(s)
π Creating a new user
π 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 Neo4J data in Reveal.
- Log into Reveal and click Dashboards -> New
π Adding a new dashboard
- Click Data Source -> OData Feed
π Adding a new OData data source
- Specify the API Server API endpoint URL, for example: https://serverurl/api.rsc
π Configuring the OData URL
- Select Generic Credentials and specify the API Server username and authentication token
π Configuring the credentials
- Select the entity you wish to visualize
π Selecting an entity to visualize (Salesforce is shown.)
- Select fields and choose a chart type
