You need to query indexer to get this kind of data, Aptos labs hosted a public indexer, ts-sdk has a bunch of built-in functions to query indexer on NFT data.

To get all NFTs by owner from a collection, you can run

  const result = await aptos.getAccountOwnedTokensFromCollectionAddress({
    accountAddress: ownerAddr,
    collectionAddress: COLLECTION_ID,
  });

If there's no built-in function in ts-sdk to do what you need, you can also write graphql by hand and query it with ts-sdk, you can find all available queries on hasura.
