Using Bootstrap 5 with Vue.js

carolskelly profile image Carol Skelly ・2 min read

It used to be that in order to use Bootstrap with Vue you had to use a 3rd party wrapper library like bootstrap-vue.

BUT, now that Bootstrap 5 no longer requires jQuery, using it in your Vue app is much easier and with no conflicts! 😲 Now that Bootstrap 5 components are written as vanilla JS plugins, you get improved alignment with Vue's best patterns & practices.

This also means it's possible to use Bootstrap 5 components without the need for a 3rd party library like bootstrap-vue.

Installing Bootstrap 5 in Vue

Install bootstrap as you would any other JS module in the Vue project using npm install or by adding it to the package.json.

Using Bootstrap 5 in Vue

The simplest way to use Bootstrap components in Vue is via the data-bs- attributes. For example here's the Bootstrap Collapse component...

        <button class="btn btn-primary" 
            data-bs-target="#collapseTarget" 
            data-bs-toggle="collapse">
            Bootstrap collapse
        </button>
        <div class="collapse py-2" id="collapseTarget">
            This is the toggle-able content!
        </div>
Enter fullscreen mode Exit fullscreen mode

Or, you can import any Bootstrap components and "wrap" them as Vue components. For example here's the Popover component...

import { Popover } from bootstrap

const popover = Vue.component('bsPopover', {
    template: `
        <slot/>
    `,
    props: {
        content: {
            required: false,
            default: '',
        },
        title: {
            default: 'My Popover',
        },
        trigger: {
            default: 'click',
        },
        delay: {
            default: 0,
        },
        html: {
            default: false,
        },
    },
    mounted() {
        // pass bootstrap popover options from props
        var options = this.$props
        var ele = this.$slots.default[0].elm
        new Popover(ele,options)
    },
})

   <bs-popover
        title="Hello Popover"
        content="This is my content for the popover!"
        trigger="hover">
        <button class="btn btn-danger">
           Hover for popover
        </button>
   </bs-popover>
Enter fullscreen mode Exit fullscreen mode

Here's another example componentizing the Collapse JS plugin:

const collapse = Vue.component('bsCollapse', {
    template: `
        <div>
            <slot name="trigger"></slot>
            <slot name="target"></slot>
        </div>
    `,
    props: {
        toggle: {
            required: false,
            default: false
        },
        id: {
            required: true
        }
    },
    mounted() {
        var trigger = this.$slots['trigger'][0].elm
        var target = this.$slots['target'][0].elm
        target.classList.add('collapse')
        target.setAttribute('id', this.id);
        trigger.setAttribute('data-bs-target', '#' + this.id);
        trigger.setAttribute('data-bs-toggle','collapse');
        new Collapse(target, {toggle: this.toggle })
    },
})

<bs-collapse id="collapse1">
       <button class="btn btn-info" slot="trigger">
            Bootstrap collapse
       </button>
       <div slot="target">Toggle the display of this collapsible content!</div>
</bs-collapse>
Enter fullscreen mode Exit fullscreen mode

Bootstrap 5 + Vue Demo

Of course using a lib like bootstrap-vue is still somewhat easier since they've already "wrapped" all the Bootstrap components for you. But this technique is helpful if you're only using Bootstrap CSS, and want the functionality of only a few JS components.
