Firebase web - close connection to the realtime database

Question

I'm using Firebase on the web, with Javascript.
how can I close the connection to the realtime DB ?

var config = {....};
firebase.initializeApp(config);

// get the firebase DB reference
var db = firebase.database().ref();

//doing something
db.push(....);

// close the firebase connection ???
db.close() || firebase.disconnect() || or something like that...

Tried lots of functions - goOffline() , close() , ect.
But nothing does the trick.

Any help would be appreciated... tnx mates

Solution 1

Try this-

firebase.initializeApp(config);

// Kill this firebase app.
firebase.app().delete().then(function() {
  firebase.initializeApp(newConfig);
});

goOffline() will close connection but Firebase will continue to work locally and the app will remain in memory.

Solution 2

Try using:

firebaseRef.off();

This will end your connection with firebase and stop communicating with the database.

Solution 3

For JSv9, as @Frank van Puffelen said, calling goOffline(db)

Disconnects from the server (all Database operations will be completed offline).

Quoted from Official Document.

Note that the db here is a Database instead of a DatabaseRef. Maybe you didn't call it in the correct way.

I looked up for this for this jest error: A worker process has failed to exit gracefully and has been force exited. This is likely caused by tests leaking due to improper teardown. Try running with --detectOpenHandles to find leaks. (I made a note here in my knowledgebase.) And adding a goOffline(db) in afterAll() actually solved it.
