Router link support
Several BootstrapVue components support rendering <router-link>
components compatible with Vue Router and Nuxt.js. For more information, see the official Vue Router docs and official Nuxt.js docs.
Common router link props
In the following sections, we are using the <b-link>
component to render router links. <b-link>
is the building block of most of BootstrapVue's actionable components. You could use any other component that supports link generation such as <b-link>
, <b-button>
, <b-avatar>
, <b-breadcrumb-item>
, <b-list-group-item>
, <b-nav-item>
, <b-dropdown-item>
, and <b-pagination-nav>
. Note that not all props are available on all components. Refer to the respective component documentation for details.
to
- type:
string | Location
- required to generate a
<router-link>
Denotes the target route of the link. When clicked, the value of the to
prop will be passed to router.push()
internally, so the value can be either a string or a location descriptor object.
<div>
<!-- Literal string -->
<b-link to="home">Home</b-link>
<!-- Renders to -->
<a href="home">Home</a>
<!-- JavaScript expression using `v-bind` -->
<b-link v-bind:to="'home'">Home</b-link>
<!-- Omitting `v-bind` is fine, just as binding any other prop -->
<b-link :to="'home'">Home</b-link>
<!-- Same as above -->
<b-link :to="{ path: 'home' }">Home</b-link>
<!-- Named route -->
<b-link :to="{ name: 'user', params: { userId: 123 } }">User</b-link>
<!-- With query, resulting in `/register?plan=private` -->
<b-link :to="{ path: 'register', query: { plan: 'private' } }">Register</b-link>
<!-- Render a non-router link by omitting `to` and specifying an `href` -->
<b-link href="/home">Home</b-link>
</div>
replace
- type:
boolean
- default:
false
Setting replace
prop will call router.replace()
instead of router.push()
when clicked, so the navigation will not leave a history record.
<div>
<b-link :to="{ path: '/abc'}" replace></b-link>
</div>
append
- type:
boolean
- default:
false
Setting append
prop always appends the relative path to the current path. For example, assuming we are navigating from /a
to a relative link b
, without append
we will end up at /b
, but with append
we will end up at /a/b
.
<div>
<b-link :to="{ path: 'relative/path'}" append></b-link>
</div>
router-tag
- type:
string
- default:
'a'
Sometimes we want <router-link>
to render as another tag, e.g <li>
. Then we can use router-tag
prop to specify which tag to render to, and it will still listen to click events for navigation. router-tag
translates to the tag
prop on the final rendered <router-link>
.
<div>
<b-link to="/foo" router-tag="li">foo</b-link>
<!-- Renders as -->
<li>foo</li>
</div>
Note: Changing the tag from anything other than <a>
is discouraged, as it hinders accessibility of keyboard and/or screen-reader users, and is also not very SEO friendly.
active-class
- type:
string
- default:
'router-link-active'
('nuxt-link-active'
when using Nuxt.js)
Configure the active CSS class applied when the link is active. Note the default value can also be configured globally via the linkActiveClass
router constructor option.
With components that support router links (have a to
prop), you will want to set this to the class 'active'
(or a space separated string that includes 'active'
) to apply Bootstrap's active styling on the component when the current route matches the to
prop.
exact
- type:
boolean
- default:
false
The default active class matching behavior is inclusive match. For example, <b-link to="/a">
will get this class applied as long as the current path starts with /a/
or is /a
.
One consequence of this is that <b-link to="/">
will be active for every route! To force the link into "exact match mode", use the exact
prop:
<div>
<!-- This link will only be active at `/` -->
<b-link to="/" exact></b-link>
</div>

exact-active-class
- type:
string
- default:
'router-link-exact-active'
('nuxt-link-exact-active'
when using Nuxt.js) - availability: Vue Router 2.5.0+
Configure the active CSS class applied when the link is active with exact match. Note the default value can also be configured globally via the linkExactActiveClass
router constructor option.
With components that support router links (have a to
prop), you will want to set this to the class 'active'
(or a space separated string that includes 'active'
) to apply Bootstrap's active styling on the component when the current route matches the to
prop.
exact-path
- type:
boolean
- default:
false
- availability: Vue Router 3.5.0+
Allows matching only using the path
section of the url, effectively ignoring the query
and the hash
sections.
<!-- this link will also be active at `/search?page=2` or `/search#filters` -->
<router-link to="/search" exact-path> </router-link>
exact-path-active-class
- type:
string
- default:
'router-link-exact-path-active'
- availability: Vue Router 3.5.0+
Configure the active CSS class applied when the link is active with exact path match. Note the default value can also be configured globally via the linkExactPathActiveClass
router constructor option.
With components that support router links (have a to
prop), you will want to set this to the class 'active'
(or a space separated string that includes 'active'
) to apply Bootstrap's active styling on the component when the current route matches the to
prop.
Nuxt.js specific router link props
When BootstrapVue detects that your app is running under Nuxt.js, it will render a <nuxt-link>
sub component instead of a <router-link>
. <nuxt-link>
supports all of the above router link props, plus the following additional Nuxt.js specific props.
prefetch
- type:
boolean
- default:
null
- availability: Nuxt.js 2.10.0+ and BootstrapVue 2.15.0+
To improve the responsiveness of your Nuxt.js applications, when the link will be displayed within the viewport, Nuxt.js will automatically prefetch the code splitted page. Setting prefetch
to true
or false
will overwrite the default value of router.prefetchLinks
configured in the nuxt.config.js
configuration file.
Примечания:
- If you have are using a version of Nuxt.js
< 2.10.0
, then this prop will have no effect. - Remember to
v-bind
the prop value (e.g.:prefetch="true"
or:prefetch="false"
).
Prefetching support requires IntersectionObserver to be supported (see Can I use). For browsers that do not support IntersectionObserver, you can use the following conditional polyfill in nuxt.config.js
:
export default {
head: {
script: [
{
src: 'https://polyfill.io/v3/polyfill.min.js?features=es2015%2CIntersectionObserver',
body: true
}
]
}
}
no-prefetch
- type:
boolean
- default:
false
- availability: Nuxt.js 2.4.0+
To improve the responsiveness of your Nuxt.js applications, when the link will be displayed within the viewport, Nuxt.js will automatically prefetch the code splitted page. Setting no-prefetch
will disabled this feature for the specific link.
Note: If you have prefetching disabled in your nuxt.config.js
configuration (router: { prefetchLinks: false }
), or are using a version of Nuxt.js < 2.4.0
, then this prop will have no effect.
Third-party router link support
v2.15.0+
BootstrapVue auto detects using <router-link>
and <nuxt-link>
link components. Some 3rd party frameworks also provide customized versions of <router-link>
, such as Gridsome's <g-link>
component. BootstrapVue can support these third party <router-link>
compatible components via the use of the router-component-name
prop. All vue-router
props (excluding <nuxt-link>
specific props) will be passed to the specified router link component.
Примечания:
- The 3rd party component will only be used when the
to
prop is set. - Not all 3rd party components support all props supported by
<router-link>
, nor do not support fully qualified domain name URLs, nor hash only URLs. Refer to the 3rd party component documentation for details.
router-component-name
- type:
string
- default:
undefined
- availability: BootstrapVue 2.15.0+
Set this prop to the name of the <router-link>
compatible component, e.g. 'g-link'
for Gridsome.
If left at the default, BootstrapVue will automatically select <router-link>
or <nuxt-link>
.
