How to get the Keys in firebase?

Question

Hey there i am trying to get the random generated key of datasets from a firebase. like this:

projects ---12345 ---67890 ...

i just would like to get the key and safe it to another part in the Database.

I tried that: but it gives me everything under the node.

getKEY(){ 
    firebase.database().ref('project').once('value', function(snapshot) {
    console.log("Key" +  JSON.stringify(snapshot.val())  )       
 });
}

can some one help me out with that? How to get only the Key generated by firebase?

i would like to get these Keys and save it to another dataset but i don't know how to access them?

There is no way through the JavaScript SDK to get the keys without also getting the data under it. See https://stackoverflow.com/questions/32442546/firebase-retrieve-child-keys-but-not-values — Frank van Puffelen, May 20 '18 at 20:58

Try the following:

getKEY(){ 
firebase.database().ref('project').once('value', function(snapshot) {
snapshot.forEach(function(child) {
var keys=child.key;   
  });   
 });
}
