In the process of developing a Vue component that will be released once completed, I am wrapping Clusterize.js (note that the vue-clusterize component is only compatible with v1.x). The goal is to efficiently render a large list of items using Vue, particularly for a table. I experimented with vue-virtual-scroll but it does not support tables and the performance was subpar. Thus, I turned my attention to Clusterize.js.
To ensure high configurability of this component, I have planned to allow users to provide a scoped slot for each row in the items list where they can manipulate the item data. However, I encountered an issue when trying to assign the scoped slot from the Clusterize components to each row before mounting the component.
Below are snippets of the MVP code:
clusterize.vue
Template
<div class="clusterize">
<table>
<thead>
<tr>
<th>Headers</th>
</tr>
</thead>
</table>
<div
ref="scroll"
class="clusterize-scroll">
<table>
<tbody
ref="content"
class="clusterize-content">
<tr class="clusterize-no-data">
<td>Loading...</td>
</tr>
</tbody>
</table>
</div>
Script
import Vue from 'vue';
import Clusterize from 'clusterize.js';
export default {
name: 'Clusterize',
props: {
items: {
type: Array,
required: true,
},
},
data() {
return {
clusterize: null,
};
},
computed: {
rows() {
return this.items.map(item => '<tr><slot :item="1"/></tr>');
},
},
watch: {
rows() {
this.clusterize.update(this.rows);
},
},
mounted() {
const scrollElem = this.$refs.scroll;
const contentElem = this.$refs.content;
this.clusterize = new Clusterize({
rows: this.rows,
scrollElem,
contentElem,
});
this.clusterize.html = (template) => {
contentElem.innerHTML = template;
const instance = new Vue({ el: contentElem });
instance.$slots = this.$slots;
instance.$scopedSlots = this.$scopedSlots;
instance.$mount();
console.log(instance.$scopedSlots); // empty
console.log(instance.$slots) // not empty
};
},
};
component.vue
<clusterize :items="test">
<template slot-scope="props">
item
</template>
</clusterize>
The challenge arises when attempting to utilize scoped slots, as without them, the component functions flawlessly. Your assistance or advice on this matter would be greatly appreciated. Thank you in advance.
