bookmark_borderHow to delete all documents from a collection in Google Cloud Firestore?

Posted on by kalkus

To delete all documents from a Firebase collection in Firestore we need to get the collection, iterate over its elements and delete each one of them:

const db = new Firestore({
  projectId: "projectId",
  keyFilename: "./key.json"
});

db.collection("collectionName")
  .get()
  .then(res => {
    res.forEach(element => {
      element.ref.delete();
    });
  });
