Vue / Nuxt.js - Calculate total value of nested JSON values
0
Using Nuxt async data, I am fetching a JSON object with a nested array in the following format:
"topic_list": {
"topics": [
{
"id": 9148,
"title": "A",
"views": 12
},
{
"id": 3228,
"title": "B",
"views": 88
}
]
}
The data is being loaded asynchronously:
export default {
data () {
return { topics: 'default', users: '0', views: '0', total: }
},
asyncData ({ params }, callback) {
axios.get(`data.json`)
.then((res) => {
callback(null, { topics: res.data.topic_list.topics, users: res.data.users,
})
})
}
}
I would like to know what would be the best approach to calculating the sum total of all views. I am aware of reduce() and imagine these values need to be pushed into an array - but how to do this with data loaded asynchronously?

you need computed property for total, where you need to check fortopicsupdates

How can you get all the views array data?res.data.views?

Just sum the views
callback(null, { topics: res.data.topic_list.topics, users: res.data.users, totalOfViews:
res.data.topic_list.topics.reduce((sum, currentItem) => (currentItem.views + sum), 0) })
This will add the views:
res.data.topic_list.topics.reduce((sum, currentItem) => (currentItem.views + sum), 0)
