Question: So I am trying to fetch data from Firestore, when I console log it I got the content of my collection back, but when I move the code to a function I am not able to return it back.

This code works:

```
const db = firebase.firestore();
db.settings({ timestampsInSnapshots: true});
db.collection('story').get().then((snapshot) => {
snapshot.docs.forEach(doc => {console.log(doc.data())
    ;})
})

```

This doesnt work. (it compiles, but doesn`t return anything):

```
...
getMyStory = () => {
        const db = firebase.firestore();
        db.settings({ timestampsInSnapshots: true});
        db.collection('story').get().then((snapshot) => {
        snapshot.docs.forEach(doc => {
            let items = doc.data();
        })
        });
        return this.items;
    }

    render () {

        return (
        <p>{this.getMyStory}</p>
);
}

```

What am I doing wrong?

Based in your code *return this.items;* executed first and then resolve *db.collection('story').get()*, finally never get the results. 

Basically this line:

```
db.collection('story').get()

```

it's a promise then you must wait that resolve the result, below code:

```
getMyStory = () => {
    const db = firebase.firestore();

    db.settings({ timestampsInSnapshots: true});

    return db.collection('story').get()
}

```

=======================EDIT=========================

```
getMyStory().then((snapshot) => {
    const listItems = snapshot.map((element) =>
      <li>{element}</li>
    );

    ReactDOM.render(
      <ul>{listItems}</ul>,
      document.getElementById('root')
    );
});

if any one is using React with Redux with Firebase and has difficulty here is how to do it
here i get all the publications from firestore using redux

```
// publicationsActions.js

var publicationsRef = db.collection("publications")
var publicationsList = []

// Function that returns the publications list
export const getPublications = () => async (dispatch) => {
    await publicationsRef.get().then((res) => {
        res.docs.forEach(doc => {
            publicationsList.push(doc.data())
        })
        dispatch({
            type: GET_PUBS,
            payload: publicationsList
        })
    })
}

// publicationReducer.js

export default function (state = initialState, action) {
    switch(action.type){
        case GET_PUBS:
            return {
                ...state,
                items: action.payload
            }
        case ADD_PUB:
            return {
                ...state,
                items: [action.payload, ...state.items]
            }
        default:
            return state; 
    }
}

```
