Getting metadata entries attached to a mosaic

Get the list of metadata entries attached to an mosaic.

Prerequisites

Complete assigning metadata entries to a mosaic guide.

Method #01: Using the SDK

// replace with mosaic id
const mosaicIdHex = '0DC67FBE1CAD29E3';
const mosaicId = new MosaicId(mosaicIdHex);
// replace with node endpoint
const nodeUrl = 'NODE_URL';
const repositoryFactory = new RepositoryFactoryHttp(nodeUrl);
const metadataHttp = repositoryFactory.createMetadataRepository();

const searchCriteria = {
  targetId: mosaicId,
  metadataType: MetadataType.Mosaic,
};
metadataHttp.search(searchCriteria).subscribe(
  (metadataEntries: Page<Metadata>) => {
    if (metadataEntries.pageSize > 0) {
      console.log('Page', metadataEntries.pageNumber);
      metadataEntries.data.map((entry: Metadata) => {
        const metadataEntry = entry.metadataEntry;
        console.log('\n \n Key:\t', metadataEntry.scopedMetadataKey);
        console.log('\n ---');
        console.log('\n Value:\t', metadataEntry.value);
