dataSets

An async function that returns a list of data sets to make available to the user.

Parameters

We will call this function with a single argument containing the following information;

type IdentityConfig = {
  dashboardAccess: {
    accessType: "standard" | "admin";
 
    organisationId: string;
 
    // Unique identifier for the user
    userReference: string;
 
    // ISO 8601 format.
    expires: string;
 
    // Signature to verify this object hasn't been tampered with.
    // Use your Vizzly public key to verify this.
    signature: string;
  };
  dataAccess?: {
    dataSetIds: string[] | "*";
 
    // Secure filters which are sent with every query for
    // a given data set.
    secureFilters: {
      [dataSetId: string]: Array<Query.Filter>;
    };
 
    // ISO 8601 format.
    expires: string;
 
    // Signature to verify this object hasn't been tampered with.
    // Use your Vizzly public key to verify this.
    signature: string;
  };
};

The dataAccess object is optional, and will only be provided if your identity callback returns a data access token.

Return value

From this dataSets function, you should return an array of data sets. If there is an error, you should return null.

Array<{
  // ID of the data set.
  id: string;
 
  // Public name of the data set, displayed to your users.
  name: string;
 
  // Fields that make up the data set.
  fields: Array<{
    // Unique constant that identifies this field.
    id: string;
 
    // Public name of the field, displayed to your users.
    publicName: string;
 
    // Data type of the field
    dataType: "number" | "boolean" | "string" | "date_time";
 
    // Can this field be used as a dimension? Default: true
    canBeDimension?: boolean;
 
    // Can this field be used as a measure? Default: true
    canBeMeasure?: boolean;
 
    // What date/time granularities can be used on this field
    // Note; only valid for fields with a dataType of `date_time`.
    allowedGranularities?: Array<
      "second" | "minute" | "hour" | "day" | "month" | "year"
    >;
  }>;
}>;
