API Changes (6)

  • (v2.6.1) /api/:dataSource/visualizations/:id/duplicate now returns the ID of the new visualization copy, instead of a full visualization.
  • (v2.6.0) GET /api/:dataSource/graph/schema/nodeTypes and GET /api/:dataSource/graph/schema/edgeTypes response body has changed to accomodate the accessibility of a given node/edge type by the user invoking the API. New response body:
type AccessLevel = "readable" | "editable" | "writable";
 
interface SchemaResult {
  // access-level for any category/type (for write-all and admins)
  any: {
    access: AccessLevel;
  };
 
  // access-level for specific categories/types
  results: Array<{
    name: string;
    access: AccessLevel;
    count?: number;
    properties?: Array<{
      key:string;
      count?:number;
      type?:string;
    }>;
  }>;
}
  • (v2.6.0) The new API GET /api/customFiles is introduced.
  • (v2.6.0) The search API no longer returns result highlighted and grouped per category. While the input is unchanged, the output of GET /api/:dataSource/search/:type is an object in the following format:
{
  "type": "node" | "edge",
  "totalHits": number,
  "results": Node[] | Edge[]
}
  • (v2.6.0) The following API have changed the way the output is returned:
  • Expand API
  • Search APIs
  • Run query API
  • Get node or edge APIs

The output, where before was in the format:

  {
    "nodes": Array<{..., edges: Edge[], ...}>
  }

Now it's in the format:

  {
    "nodes": Node[],
    "edges": Edge[]
  }

The edges are no longer contained in each node. To retrieve the nodes from the edges, it's necessary to look at the source and target property of the edge that contain the IDs of the nodes.

  • (v2.6.0) The following APIs have now the possibility to fetch edges between the result of the API and a list of node ids.
  • Expand API
  • Search API
  • Get node and edge API
  • Execute query API

A new option "edgesTo", has been added to the APIs to allow to specify the list of node ids to fetch the edges towards to. The same option was available only in the Expand API and was called "visibleNodeIds", now not available anymore.
