Enhancing Vue 3 Applications with PrimeVue: Tree Nodes & Accordions
Written on
Chapter 1: Introduction to PrimeVue
PrimeVue is a user interface framework designed to work seamlessly with Vue 3. In this section, we will delve into the basics of developing Vue 3 applications utilizing PrimeVue.
Section 1.1: Customizing Tree Node Content
In PrimeVue, we can personalize the content displayed in tree nodes through the default and URL slots. Here’s an example of how to implement this:
<template>
<div>
<Tree :value="nodes" :expandedKeys="expandedKeys">
<template #default="slotProps">
<b>{{ slotProps.node.label }}</b></template>
<template #url="slotProps">
<a :href="slotProps.node.data">{{ slotProps.node.label }}</a></template>
</Tree>
</div>
</template>
<script>
export default {
name: "App",
data() {
return {
expandedKeys: undefined,
nodes: [
{
key: "0",
label: "Introduction",
children: [
],
},
{
key: "1",
label: "Components In-Depth",
children: [
],
},
],
};
},
methods: {},
};
</script>
We can access the node data through the slotProps.node property in each slot. Additionally, a filter slot can be added to incorporate a text input for searching nodes.
Section 1.2: Implementing Accordions
PrimeVue also offers an accordion component, which allows us to organize content into collapsible tabs. To use it, we can write:
main.js
import { createApp } from "vue";
import App from "./App.vue";
import PrimeVue from "primevue/config";
import Accordion from 'primevue/accordion';
import AccordionTab from 'primevue/accordiontab';
import 'primevue/resources/primevue.min.css';
import 'primevue/resources/themes/saga-blue/theme.css';
import 'primeicons/primeicons.css';
import 'primeflex/primeflex.css';
const app = createApp(App);
app.use(PrimeVue);
app.component("Accordion", Accordion);
app.component("AccordionTab", AccordionTab);
app.mount("#app");
In the App.vue file, we can structure the accordion as follows:
<template>
<div>
<Accordion>
<AccordionTab header="Header 1"> Content </AccordionTab>
<AccordionTab header="Header 2"> Content </AccordionTab>
<AccordionTab header="Header 3"> Content </AccordionTab>
</Accordion>
</div>
</template>
<script>
export default {
name: "App",
data() {
return {};},
methods: {},
};
</script>
We register both the Accordion and AccordionTab components to allow for the addition of tabs. The content can be placed within the default slot of AccordionTab, and the headers are defined with simple strings. The multiple prop on Accordion permits multiple tabs to remain open simultaneously, while the disabled prop on AccordionTab can be used to disable certain tabs.
For custom content in the header, we can utilize the header slot:
<template>
<div>
<Accordion>
<AccordionTab>
<template #header>
<i class="pi pi-calendar p-mr-2"></i>
<span>Header 1</span>
</template>
Content
</AccordionTab>
<AccordionTab header="Header 2"> Content </AccordionTab>
<AccordionTab header="Header 3"> Content </AccordionTab>
</Accordion>
</div>
</template>
<script>
export default {
name: "App",
data() {
return {};},
methods: {},
};
</script>
Conclusion
Through the use of PrimeVue, we can effectively incorporate customizable tree nodes and accordion components into our Vue 3 applications, enhancing user experience and interface design.
