fetchEntityAggregateScorefromChain

fetchEntityAggregateScorefromChain(entity, ratingType?): Promise<IAggregateScore[] | null>

Fetches and aggregates scores for a specific entity from the blockchain.

This asynchronous function retrieves aggregate score data for a given entity from the blockchain. If a specific rating type is provided, it fetches the aggregate score for that rating type. Otherwise, it fetches aggregate scores across all rating types. The function decodes the retrieved data into a readable and structured format (IAggregateScore). This function is crucial for analyzing and presenting an overview of how an entity is rated across different parameters or overall.

Parameters

• entity: string

The identifier of the entity for which aggregate scores are to be fetched.

• ratingType?: RatingTypeOf

(Optional) The specific rating type to fetch the aggregate score for.

Returns

Promise<IAggregateScore[] | null>

• A promise that resolves to an array of aggregate score objects, or null if no data is found.

Example

// Example usage of the function to fetch aggregate scores for a specific entity and rating type
const entityId = 'entity123';
const ratingType = RatingTypeOf.overall;

fetchEntityAggregateScorefromChain(entityId, ratingType)
  .then(aggregateScores => {
    if (aggregateScores) {
      console.log('Aggregate Scores:', aggregateScores);
    } else {
      console.log('No aggregate scores found for the specified entity and rating type.');
    }
  })
  .catch(error => {
    console.error('Error fetching aggregate scores:', error);
  });
