Leveraging Vue mixin within a @Component

After implementing the vue-property-decorator package, I encountered an issue when trying to use a mixin method inside the beforeRouteEnter hook.

Here is what I initially tried:

import { Component, Mixins } from 'vue-property-decorator';
import { myMixin } from '../mixins';

@Component({})
export default class myClass extends Mixins(myMixin) {
  beforeRouteEnter(to, from, next) {
    next(vm => {
      vm.callMixinMethod();
    })
  }
}

The problem with this approach is that the types of to, from, next, and vm are not automatically assigned.

To address this issue, I moved the beforeRouteEnter hook into @Component:

@Component({
  beforeRouteEnter(to, from, next) {
    next(vm => {
      vm.callMixinMethod();
    })
  }
})

This solution successfully assigns types automatically. However, a new problem arises as the mixin method is no longer defined within @Component. This results in the error message:

Property 'callMixinMethod' does not exist on type 'Vue'

I attempted to register mixins inside @Component like so:

@Component({
  mixins: [myMixin],
  beforeRouteEnter...
})

Unfortunately, this did not resolve the issue.

Is there a way to enable the beforeRouteEnter hook inside @Component to access the methods of imported mixins? Perhaps by extending vm with mixins somehow?

Answer №1

Upon my investigation, I discovered a method to manually assign a type to the vm in the following manner:

@Component({
beforeRouteEnter(to, from, next) {
    next(vm: myCustomClass & myCustomMixin => {
      vm.callMixinMethod();
    })
  }
})
export default class myCustomClass extends Mixins(myCustomMixin) {
}

The structure of myCustomMixin is as follows:

@Component({})
export default class myCustomMixin extends Vue {
  public callMixinMethod() {
    // perform certain actions
  }
}
