A guide on transforming a Firebase Snapshot child into a personalized object in a React Native environment

I'm looking for a way to retrieve data from Firebase Realtime Database and display it in FlatList format. What is the most efficient method for extracting the child value and converting it into a custom object?

For example:

class CustomObject {

    constructor(id, name, age) {
        this.id = id;
        this.name = name;
        this.age = age;
    }
}

export default new CustomObject();

// In my Screen.js file, here's how I retrieve the data...
useEffect(() => {
    reference
      .on('value', snapshot => {
        
        let data = [];
       
        snapshot.forEach((child) => {
          // Need to convert child.val() into a CustomObject
          data.push(child.val());
        })

        setArr(data);
      });
  });

Answer №1

Experiment with spreading the value in this manner and subsequently adding it to your collection:

const freshObject = new Model ({...data.val()})

Does this match your desired outcome?
