I am developing react native project using firebase as backend. And I am using firebase realtime database for saving user information now. I want to get only special field from realtime database. For example, I want to get only user information that email is "devsmith@gmail.com" like following image. Please help me. Thanks.
You should use @react-native-firebase/database to get your user's data
(doc in Realtime Database section => https://rnfirebase.io)
You should use react native firebase
The specific answer is in the Query section:
You will have to use the where operator like so :
import firestore from '@react-native-firebase/firestore';
// ...
firestore()
.collection('user')
// Filter results
.where('email', '==', 'devsmith@gmail.com')
.get()
.then(querySnapshot => {
/* ...do what you want with this querySnapshot */
}
