To create dynamic breadcrumbs in Vue.js, you can use a combination of route navigation guards and a tracked breadcrumb trail object.
Here's a step-by-step guide on how to achieve this:
- Create a breadcrumb component that will render the list of breadcrumb links.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 |
<template>
<nav>
<ol class="breadcrumbs">
<li v-for="(crumb, index) in breadcrumbs" :key="index">
<router-link :to="crumb.path">{{ crumb.label }}</router-link>
</li>
</ol>
</nav>
</template>
<script>
export default {
data() {
return {
breadcrumbs: []
};
},
mounted() {
this.updateBreadcrumbs();
},
watch: {
$route() {
this.updateBreadcrumbs();
}
},
methods: {
updateBreadcrumbs() {
const matchedRoutes = this.$route.matched;
this.breadcrumbs = matchedRoutes.map(route => ({
label: route.meta.title,
path: route.path
}));
}
}
};
</script>
<style>
.breadcrumbs {
list-style-type: none;
padding: 0;
margin: 0;
}
</style>

- Define the breadcrumb metadata in your router configuration.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
const routes = [
{
path: '/',
component: Home,
meta: {
title: 'Home'
}
},
{
path: '/about',
component: About,
meta: {
title: 'About Us'
}
},
{
path: '/contact',
component: Contact,
meta: {
title: 'Contact Us'
}
}
]
|
- Add the breadcrumb component to your main App.vue file.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
<template>
<div id="app">
<breadcrumb />
<router-view />
</div>
</template>
<script>
import Breadcrumb from './Breadcrumb.vue';
export default {
components: {
Breadcrumb
}
};
</script>

With these steps, you'll have a dynamic breadcrumb component that updates based on the current route in your Vue.js application. Make sure to customize the breadcrumb component and route metadata according to your application's navigation structure.
