I am able to add data in firebase, but its throwing error on using onSnapshot — Md. Parvez Alam, Mar 25 '19 at 12:13
did you follow this documentation [rn-firebase](https://rnfirebase.io/docs/v4.3.x/installation/initial-setup#Creating-a-new-project) ?? — Ron Astle Lobo, Mar 25 '19 at 12:16
yes getting error here this.unsubscribe = firebase.firestore().collection('locations').onSnapshot(this.getCollectionData — Md. Parvez Alam, Mar 25 '19 at 12:20
Could you try this code `firebase .firestore() .collection("locations") .get() .then(QuerySnapshot => { console.log( QuerySnapshot._docs.length); });` — Ron Astle Lobo, Mar 25 '19 at 12:33
Yes I did, I am able to add data, but unable to get , when I did "firebase.firestore().collection('locations').doc('test').set({ test: 'test' })" it is able to add data data in firestore — Md. Parvez Alam, Mar 25 '19 at 13:10
add documents like this `firebase.firestore().collection('locations').add({ test: 'test' })` and check. — Ron Astle Lobo, Mar 25 '19 at 13:20
There is not issue with add or set,,, the issue is with fetch only — Md. Parvez Alam, Mar 25 '19 at 13:25
there could be problem with document creating. Just give a try with the abov code for both adding and retrival — Ron Astle Lobo, Mar 25 '19 at 13:27
