How can I write my component to wrap another vue component, while my wrapper component get some extra props? My wrapper template component should be:
<wrapper-component>
<v-table></v-table> <!-- pass to v-table all the props beside prop1 and prop2 -->
</wrapper-component>
and the wrapper props:
props: {
prop1: String,
prop2: String
}
Here I want to wrap a table component, and pass to the table component all the props and events that were passed to the wrapper, beside two extra props prop1
and prop2
. What is the correct way of doing this in vue? And is there a solution for events too?
Place the component you wish to wrap into the template of the wrapper component, add v-bind="$attrs" v-on="$listeners"
to that component tag, then add the inner component (and, optionally, inheritAttrs: false
) to the wrapper component's config object.
Vue's documentation doesn't seem to cover this in a guide or anything, but docs for $attrs , $listeners , and inheritAttrs can be found in Vue's API documentation . Also, a term that may help you when searching for this topic in the future is " Higher-Order Component " (HOC) - which is basically the same as your use of "wrapper component". (This term is how I originally found $attrs)
For example...
<!-- WrapperComponent.vue -->
<template>
<div class="wrapper-component">
<v-table v-bind="$attrs" v-on="$listeners"></v-table>
</div>
</template>
<script>
import Table from './BaseTable'
export default {
components: { 'v-table': Table },
inheritAttrs: false // optional
}
</script>
Edit : Alternatively, you may want to use dynamic components via the is
attribute so you can pass in the component to be wrapped as a prop (closer to the higher-order component idea) instead of it always being the same inner component. For example:
<!-- WrapperComponent.vue -->
<template>
<div class="wrapper-component">
<component :is="wraps" v-bind="$attrs" v-on="$listeners"></component>
</div>
</template>
<script>
export default {
inheritAttrs: false, // optional
props: ['wraps']
}
</script>
Edit 2 : The part of OP's original question that I missed was passing all props EXCEPT one or two. This is handled by explicitly defining the prop on the wrapper. To quote the documentation for $attrs
:
Contains parent-scope attribute bindings (except for class and style) that are not recognized (and extracted) as props
For example, example1
is recognized and extracted as a prop in the snippet below, so it doesn't get included as part of the $attrs
being passed down.
Vue.component('wrapper-component', { template: ` <div class="wrapper-component"> <component :is="wraps" v-bind="$attrs" v-on="$listeners"></component> </div> `, // NOTE: "example1" is explicitly defined on wrapper, not passed down to nested component via $attrs props: ['wraps', 'example1'] }) Vue.component('posts', { template: ` <div> <div>Posts component</div> <div v-text="example1"></div> <div v-text="example2"></div> <div v-text="example3"></div> </div> `, props: ['example1', 'example2', 'example3'], }) new Vue({ el: '#app', template: ` <wrapper-component wraps="posts" example1="example1" example2="example2" example3="example3" ></wrapper-component> `, })
