How I get the generated document ID of a collection in Firestore?

CodePudding user response：

If you want to add a document to firestore with an auto id, you can use the add method on the collection with the data of the document.

If you want to get the id of a Firestore doc, call doc.id. This is not in doc.data and confused me as well.

const docs = await getDocs(collection(db, 'collection_name'));
docs.forEach((doc) => {
  console.log(doc.id);
});
