Question

How can we best organize a VueJS application to accommodate this specific logic?

I am currently working on an app that needs to display data fetched from multiple sources based on a condition. The issue I am facing is that the process of fetching, organizing, and returning the data varies depending on the source, sometimes even requiring me to import additional libraries for just one method.

My current setup is similar to the example provided below. However, as my list of data sources continues to expand, I am concerned about scalability. How should I structure the app to accommodate a potentially large number of sources? Any guidance would be greatly appreciated!

<template>
    <div>
        <h1>{{data.title}}</h1>
        <h2>{{data.subtitle}}</h2>
        <p>{{data.description}}</p>
    </div>
</template>

<script>
export default {
    data() {
            return {
                data: {}
            }
        },
        methods: {
            getFetchMethod() {
                var i = Math.floor(Math.random() * 3);
                if (i == 0) {
                    this.getData();
                } else if (i == 1) {
                    this.getDataThisWay();
                } else if (i == 2) {
                    this.getDataAnotherWay();
                } else {
                    this.getDataEtc();
                };
            },
            getData() {
                this.data = {
                    'title': 'Foo',
                    'subtitle': 'Bar',
                    'description': 'Blah'
                };
            },
            getDataThisWay() {
                this.data = {
                    'title': 'Foo',
                    'subtitle': 'Bar',
                    'description': 'Blah'
                };
            },
            getDataAnotherWay() {
                this.data = {
                    'title': 'Foo',
                    'subtitle': 'Bar',
                    'description': 'Blah'
                };
            },
            getDataEtc() {
                this.data = {
                    'title': 'Foo',
                    'subtitle': 'Bar',
                    'description': 'Blah'
                };
            }
        },
        mounted() {
            this.getFetchMethod();
        }
}

If you're working with VueJS, it's important to understand how to handle data effectively. One way to do this is by creating an array of objects, each containing its own data set. Then, you can use a random number as an index to access the data.

// Store all your data in an array
var datasets = [
    {
        title: 'Foo',
        subtitle: 'Bar',
        description: 'Blah'
    },
    {
        title: 'Foo2',
        subtitle: 'Bar2',
        description: 'Blah2'
    }
    // Add more objects here...
];

// Generate a random number based on the array length
var i = Math.floor(Math.random() * datasets.length);

// Use the random number as an index to retrieve data
this.data = datasets[i];

UPDATE: If you have multiple functions that retrieve data differently, you can organize them into an array and access them using indexes.

// Store method references in an array
var methods = [
    this.getData,
    this.getDataThisWay,
    this.getDataEtc
];

var i = Math.floor(Math.random() * datasets.length);

// Call a specific method based on the index
this.data = datasets[i]();

Furthermore, if your methods require a specific context, you can use the call() method to provide a different context than the default this.

this.data = datasets[i].call(this); // Use a specific context

To enhance the efficiency of our code, I would suggest creating a separate component for the template that accepts props like title, subtitle, and description. The parent component can then pass the required data to this child component based on how it retrieves the data.

Child.vue

<template>
    <div>
        <h1>{{title}}</h1>
        <h2>{{subtitle}}</h2>
        <p>{{description}}</p>
    </div>
</template>

<script>
export default {
    props: ["title", "subtitle", "description"]
}
</script>

Parent.vue

<template>
    <div>
        <button @click="way1">Way 1</button>
        <button @click="way2">Way 2</button>
        <child :title="title" :subtitle="subtitle" :description="description"></child>
    </div>
</template>

<script>
import Child from "./Child.vue"

export default {
    components:{
        Child
    },
    data(){
        return {
            title: "",
            subtitle: "",
            description: ""
        };
    },
    methods: {
        way1(){
            this.title="way 1 title";
            this.subtitle="way 1 subtitle"
            this.description="way 1 description"
        },
        way2(){
            this.title="way 2 title";
            this.subtitle="way 2 subtitle"
            this.description="way 2 description"
        }
    }
}
</script>

EDIT: It is also advisable to import a "data provider" into Parent.vue to handle data retrieval logic. This provider should return data in a defined format that can easily be passed to the child component.

Parent2.vue

<template>
    <div>
        <button @click="get">Get</button>
        <child :title="title" :subtitle="subtitle" :description="description"></child>
    </div>
</template>

<script>
import dataProvider from "./dataProvider"
import Child from "./Child.vue"

export default {
    components:{
        Child
    },
    data(){
        return {
            title: "",
            subtitle: "",
            description: ""
        };
    },
    methods: {
        get(){
            var data = dataProvider.get();
            this.title=data.title;
            this.subtitle=data.subtitle;
            this.description=data.description;
        }
    }
}
