How do insert multiple entities and return them in TypeORM

Question

Let's say i have a Vote entity. I want to insert an array with 5 votes simultaneously and return them. I have tried : await Vote.save(votes) but that doesnt work and it doesnt return them either. Any ideas?

Firstly you need to prepare entities instances (it's not just an object which you must probably have made in some place):

const votesEntities = Vote.create(votes);

And then you could save these entities:

await Vote.save(votesEntities);

But I would advise to use an insert instead of save (because save forms a separate query to DB for each entity) and return previously prepared entities. How it might look in the end:

async insertVotes(votes) {
  const votesEntities = Vote.create(votes);
  await Vote.insert(votesEntities);
  return votesEntities;
}
