Node.JS hangs after i do a basic set

[FireBoy]

This might be a dumm question but i cant find an answer in the firebase NodeJs samples or docs.

I used the sample provided and i am able to connect to Firebase Db and i can Set(insert) record 

fine but afterwards my node.JS script just sits there and i have to kill it. 

Here is the code i am using so what am i missing ?

// Get a database reference to our blog

var db = admin.database();

var ref = db.ref("server/saving-data/fireblog");

var usersRef = ref.child("users");

usersRef.set({

 alanisawesome: {

   date_of_birth: "June 23, 1912",

   full_name: "Alan Turing"

 },

 gracehop: {

   date_of_birth: "December 9, 2018",

   full_name: "Grace Hopper"

 }

});

The Firebase Node.js SDK keeps a connection to the Realtime Database open once you've first connected, so the event loop never clears. You have to manually exit the process with e.g.

return ref.set({...}).then(() => process.exit(0))

Thanks, after some digging i found that out as well. Wish they would mention that upfront in doc's / sample. The sample are great but only helpful

when they work as expected or are complete.

As I struggled with this as well, here is another way of closing the connections:

Depending on what features you use (ie. auth, firebase), some combination of the following will make your node script terminate without calling process.exit():


const app = firebase.initializeApp(...);

firebase.database().ref()
.update(...)
.then(() => firebase.database().goOffline())
.then(() => firebase.auth().signOut())
.then(() => app.delete())
