I am quite new to VueJS. In react you can easily use rest params for passing props to children. Is there a similar pattern in Vue?
Consider this parent component that has a few children components:
<template>
<header class="primary-nav">
<search-bar :config="searchBar"><search-bar>
// ^^^^ this becomes the key on the props for SearchBar
header>
</template>
export default {
data(){
return {
... a few components ...
searchBar : {
model: '',
name: 'search-bar',
placeholder: 'Search Away',
required:true,
another: true
andanother: true,
andonemoreanotherone:true,
thiscouldbehundredsofprops:true
}
}
}
}
<template>
<div :class="name">
<form action="/s" method="post">
<input type="checkbox">
<label :for="config.name" class="icon-search">{{config.label}}</label>
<text-input :config="computedTextInputProps"></text-input>
//^^^^ and so on. I don't like this config-dot property structure.
</form>
</div>
</template>
export default {
props: {
name: String,
required: Boolean,
placeholder: String,
model: String,
},
computed: {
computedtextInputProps(){
return justThePropsNeededForTheTextInput
}
}
...
What I don't like is that the props are named-spaced with the key config
, or any other arbitrary key. The text-input component ( not shown ) is a glorified input
field that can take a number of attributes. I could flatten the props when the component is created, but is that generally a good idea?
I am surprised this question hasn't been asked before.
Thanks.

Once you are satisfied with all the props, then you can use v-bind="$props" inside your child component to retrieve all the props. Show activity on this post. In Vue 2.6+ , in addition to attributes passing, events/listeners can be also passed to child components.
Parent component
<template>
<div id="app">
<child-component v-bind="propsToPass"></child-component>
</div>
</template>
<script>
import ChildComponent from './components/child-component/child-component'
export default {
name: 'app',
components: {
ChildComponent
},
data () {
return {
propsToPass: {
name: 'John',
last_name: 'Doe',
age: '29',
}
}
}
}
</script>
Child Component
<template>
<div>
<p>I am {{name}} {{last_name}} and i am {{age}} old</p>
<another-child v-bind="$props"></another-child> <!-- another child here and we pass all props -->
</div>
</template>
<script>
import AnotherChild from "../another-child/another-child";
export default {
components: {AnotherChild},
props: ['name', 'last_name', 'age'],
}
</script>
Another Child component inside the above component
<template>
<h1>I am saying it again: I am {{name}} {{last_name}} and i am {{age}} old</h1>
</template>
<script>
export default {
props: ['name', 'last_name', 'age']
}
</script>
