Tips for utilizing ES6 classes in Vue.js for code reusability

Seeking guidance on integrating existing ES6 classes with Vue Js.

I currently have a class where a variable is being updated by an observable function.

class A { 
    public a: string;
    someobservable.subscribe((a) =>{
         this.a = a;
    })
}

Within Vue.js, I have instantiated an object of this class.

Here's a sample of how the property is utilized:

created: {
    objA = new A();
}
methods: {
    getA() {
        if(this.objA !== undefined){
            return objA.a;
        }
    }
}

In the Vue template:

<div>{{getA()}}</div>

However, there seems to be a synchronization issue between the template value and the class variable.

Are there alternative methods for ensuring real-time updates in the Vue template when using properties?

Answer №1

To improve efficiency, consider using getA() as a computed property instead of a method. Additionally, you can eliminate the if statement since a return statement without a value will automatically return undefined.

computed: {
  getA() {
    return objA.a;
  }
}

When creating an instance, it is important to do so within the appropriate scope. To ensure that Vue can track any changes, instantiate your object in the data field.

data: {
    objA: new A();
},

Subsequently, you have the option to implement a method as shown below:

methods: {
    getA() {
       return this.objA.a;
    }
},

<div>{{getA()}}</div>

Alternatively, consider utilizing a computed property as suggested by others:

computed: {
    getA() {
       return this.objA.a;
    }
}

<div>{{getA}}</div>

Both approaches yield similar results, but incorporating a computed property is recommended for caching benefits.
