First of all, it's incorrect to refer to the Vue class function as "VueInstance", as it is not an instance of Vue but the actual class function itself.
To address your somewhat unclear question, it seems like you may need to implement a state management system.
If I understand correctly, you want to add a method to the Vue prototype that invokes another method within each instance of your component "Magic".
(Keep in mind that you must instantiate the component to access its methods or data, as you cannot call a method directly from the component definition).
Although this approach appears quite complex and without knowing your end goal, here are some suggestions:
- You could create an empty instance of your component to access its methods.
Import Magic from './Magic.vue';
const myMagic = new (Vue.extend(Magic));
export default {
install(VueInstance) {
console.log('Installing');
VueInstance.component('magic', Magic);
VueInstance.prototype.$magic = {
increment() {
myMagic.method()
}
};
}
};
In theory, all instances of your Magic component will share the same method. However, this does not update the state of each instance. It only provides access to the method (which may not be very useful unless used in a service/utility context).
- Instead of trying to use a method from your Magic component, consider using a shared state and method imported by the Magic component.
Shared.js
export const state = {
somedata: 0
};
export const methods = {
inc() {
state.somedata++
}
};
Magic.vue
import { state, methods} from './Shared.js'
export default {
data() {
return {
shared: state
}
},
methods: {
Something () {
methods.inc();
}
}
};
Plugin.js
import { state, methods} from './Shared.js'
import Magic from './Magic.vue';
export default {
install(VueInstance) {
console.log('Installing');
VueInstance.component('magic', Magic);
VueInstance.prototype.$magic = {
increment() {
methods.inc()
}
};
}
};
This approach ensures shared data across instances since the same reference is provided to each Magic component instance, making it reactive.
- Alternatively, employ vuex with state, mutations, or actions to achieve similar functionality as mentioned in #2.
Without clear details on your component's method requirements, it becomes challenging to offer precise recommendations. Kindly provide more specifics if none of the given solutions meet your needs.
