  console.log("Test");
  db.collection("messages").where("date",">",yesterday)
      .get().then(function(querySnapshote) {
        querySnapshote.forEach(function(doc) {
          console.log(doc.id," => ",doc.data());

      })
  .catch(function(error) {
        console.log("Error getting documents: ", error);
  });

  db.collection("messages").where("date","<",yesterday)
    .get().then(function(querySnapshote) {
      querySnapshote.forEach(element => {
        element.ref.delete();
      });
    })
