Ways to generate data following the integration of Firebase Firestore in Vue.JS

How can I display the orders data retrieved from Firebase in my browser console? See the image link below for reference.

https://i.sstatic.net/HPlaC.png

This is the code snippet for fetching data from Firebase and displaying it in the console:

orders(){
    const db = firebase.firestore();
    const dbOrderRef = db.collection('order');
    dbOrderRef.get()
        .then(res => {
            res.forEach(doc => {
                console.log(doc.data())
            })
        })
        .catch(err => {
            console.log('error', err)
        })
}

I attempted to store the data in an instance variable like so:

ordersData = []

and then assign it in a method:

this.ordersData = doc.data()

However, this did not work as expected. Any suggestions on how to achieve this goal?

Thank you

Answer №1

To clarify your question, it seems like you are looking to populate an array named ordersData with orders retrieved from a Firestore query.

You can achieve this by using the following code snippet:

const db = firebase.firestore();
const dbOrderRef = db.collection('order');

let orderArray = [];
dbOrderRef.get()
    .then(res => {
        res.forEach(doc => {
            let orderObj = doc.data();
            orderObj.id = doc.id;
            orderArray.push(orderObj);
        });
        this.ordersData = orderArray;
    })
    .catch(err => {
        console.log('error', err)
    })

Subsequently, you can render the ordersData array within your template as shown below:

            <div v-if="ordersData.length">
                <div v-for="order in ordersData">
                    <h5>{{ order.name }}</h5>
                    <p>Price: {{ order.price }}</p>
                    <p>
                     <a @click="openOrderDetail(order.id)">Open order</a>  
                     // This demonstrates how to invoke the openOrderDetail() method with the Firestore document id of the order.
                     // By doing so, you can potentially navigate to a page where you retrieve detailed information about the order based on its id.
                    </p>
                </div>
            </div>

When utilizing the then method, the keyword used inside the block pertains to the block itself rather than the Vue object. To handle this, we can create a workaround by saving the Vue reference in another variable and accessing the necessary data using that variable.

let _self = this;
const db = firebase.firestore();
const dbOrderRef = db.collection('order');
dbOrderRef.get()
    .then(response => {
        response.forEach(document => {
            _self.ordersData = document.data();
            console.log(_self.ordersData);
        })
    })
    .catch(error => {
        console.log('error', error);
    });
