Migartion of vue2 to vue 3 - how to update the mixins added in vue2 components in vue3 setup api
问题
我们最近开始将我们的应用从vue2迁移到vue3,一些组件已经添加了mixins,我想知道如何在vue 3中添加这些mixins。
我尝试了几种解决方案,但找不到像vue 2中可用的特殊hook。
export default {
name: "Modal",
components: { Loader },
mixins: []
}
```如何添加mixins?

In Vue 3, you can still use mixins in a similar way to Vue 2 when using the Options API:
const mixin = {
created() { console.log('Mixin'); },
};
export default {
name: "Modal",
components: { Loader },
mixins: [mixin]
};
But as for the Composition API, you have to use composable functions instead:
// Composable declaration function
import { onMounted } from 'vue';
export function useMixin() {
onMounted(() => console.log('Mixin'));
return {};
}
// In your component
import { useMixin } from './mixin';
import Loader from './Loader';
export default {
name: "Modal",
components: { Loader },
setup() {
useMixin();
return {};
},
};
Composable functions provide a more explicit and flexible alternative to mixins when using Vue 3's Composition API.
