The online documentation is comprised of the following sections:
Before getting started with BootstrapVue, you should have general familiarity with Vue functionality and Bootstrap v4 CSS. If you are unfamiliar with Vue and/or Bootstrap, some good starting points would be:
.vue
filesIn many of the examples shown in BootstrapVue's documentation, you may see the use of CSS classes such as ml-2
, py-1
, etc. These are Bootstrap v4.4 utility classes that help control padding, margins, positioning and more. You can find information on these classes in the Utility Classes reference section.
Many of the examples in this documentation are live and can be edited in-place for an enhanced learning experience (note some examples may not work in IE 11 due to use of ES6 JavaScript code in the <template>
sections).
BootstrapVue also provides an interactive playground where you can experiment with the various components and export your results to JSFiddle, CodePen, and/or CodeSandbox.
Bootstrap v4 CSS employs a handful of important global styles and settings that you'll need to be aware of when using it, all of which are almost exclusively geared towards the normalization of cross browser styles. Refer to the following sub-sections for details.
Bootstrap requires the use of the HTML5
doctype. Without it, you may see some funky incomplete styling, but including it shouldn't cause any considerable hiccups.
<!doctype html> <html lang="en"> ... </html>
Bootstrap is developed for mobile first, a strategy in which code is optimized for mobile devices first and then scales up components as necessary using CSS media queries. To ensure proper rendering and touch zooming for all devices, add the responsive viewport meta tag to your <head>
.
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
For more straightforward sizing in CSS, the global box-sizing
value is switched from content-box
to border-box
. This ensures padding
does not affect the final computed width of an element, but it can cause problems with some third party software like Google Maps and Google Custom Search Engine.
On the rare occasion you need to override it, use something like the following:
.selector-for-some-widget { box-sizing: content-box; }
With the above snippet, nested elements — including generated content via ::before
and ::after
— will all inherit the specified box-sizing
for that .selector-for-some-widget
.
Learn more about box model and sizing at CSS Tricks.
For improved cross-browser rendering, Bootstrap v4.4 uses Reboot to correct inconsistencies across browsers and devices while providing slightly more opinionated resets to common HTML elements.
If you are using module bundlers like Webpack, Parcel or rollup.js, you may prefer to directly include the package into your project. To get started, use yarn
or npm
to get the latest version of Vue.js, BootstrapVue and Bootstrap v4:
# With npm npm install vue bootstrap-vue bootstrap # With yarn yarn add vue bootstrap-vue bootstrap
Then, register BootstrapVue in your app entry point:
import Vue from 'vue' import { BootstrapVue, IconsPlugin } from 'bootstrap-vue' // Install BootstrapVue Vue.use(BootstrapVue) // Optionally install the BootstrapVue icon components plugin Vue.use(IconsPlugin)
And import Bootstrap and BootstrapVue css
files:
import 'bootstrap/dist/css/bootstrap.css' import 'bootstrap-vue/dist/bootstrap-vue.css'
Alternatively you can import Bootstrap and BootstrapVue scss
files in a custom SCSS file:
@import 'node_modules/bootstrap/scss/bootstrap'; @import 'node_modules/bootstrap-vue/src/index.scss';
Make sure to import the custom.scss
file in your app entry point:
import './custom.scss'
Be sure to @import
or define your custom variable values before including Bootstrap SCSS (bootstrap.scss
), and include BootstrapVue SCSS (bootstrap-vue.scss
) after that to ensure variables are set up correctly.
Place all of the SCSS @import
s into a single SCSS file, and import that single file into your project. Importing individual SCSS files into your project will not share variable values and functions between files by default.
Webpack and Parcel support prepending the scss
modules with tilde paths (~
) when importing from a scss
file:
// Webpack example @import '~bootstrap'; @import '~bootstrap-vue';
// Parcel example @import '~bootstrap/scss/bootstrap'; @import '~bootstrap-vue/src/index.scss';
For more details how to configure asset loading and how modules are resolved, please consult the module bundlers documentation.
Notes:
For information on theming Bootstrap, check out the Theming reference section.
BootstrapVue and PortalVue require access to the global Vue
reference (via import Vue from 'vue'
).
If you are using a specific build of Vue (i.e. runtime-only vs. compiler + runtime), you will need to set up an alias to 'vue'
in your bundler config to ensure that your project, BootstrapVue and PortalVue are all using the same build version of Vue. If you are seeing an error such as "$attr and $listeners is readonly"
, or "Multiple instances of Vue detected"
, then you will need to set up an alias.
Example: Vue alias in webpack.config.js
module.exports = { // ... resolve: { alias: { // If using the runtime only build vue$: 'vue/dist/vue.runtime.esm.js' // 'vue/dist/vue.runtime.common.js' for webpack 1 // Or if using full build of Vue (runtime + compiler) // vue$: 'vue/dist/vue.esm.js' // 'vue/dist/vue.common.js' for webpack 1 } } }
Note: If your project has multiple webpack config files (i.e. webpack.config.js
, webpack.renderer.config.js
, webpack.vendor.config.js
, webpack.server.config.js
, webpack.client.config.js
, etc), you will need to set the appropriate alias in all of them.
See the Vue.js Guide for full details on setting up aliases for webpack, rollup.js, Parcel, etc.
When using a module bundler you can optionally import only specific components groups (plugins), components and/or directives. Note that tree shaking only applies to the JavaScript code and not CSS/SCSS.
Note: Optimal tree shaking only works when webpack 4 is in production
mode and javascript minification is enabled.
You can import component groups and directives as Vue plugins by importing from the bootstrap-vue
:
// This imports all the layout components such as <b-container>, <b-row>, <b-col>: import { LayoutPlugin } from 'bootstrap-vue' Vue.use(LayoutPlugin) // This imports <b-modal> as well as the v-b-modal directive as a plugin: import { ModalPlugin } from 'bootstrap-vue' Vue.use(ModalPlugin) // This imports <b-card> along with all the <b-card-*> sub-components as a plugin: import { CardPlugin } from 'bootstrap-vue' Vue.use(CardPlugin) // This imports directive v-b-scrollspy as a plugin: import { VBScrollspyPlugin } from 'bootstrap-vue' Vue.use(VBScrollspyPlugin) // This imports the dropdown and table plugins import { DropdownPlugin, TablePlugin } from 'bootstrap-vue' Vue.use(DropdownPlugin) Vue.use(TablePlugin)
When importing as plugins, all subcomponents and related directives are imported in most cases. i.e. When importing <b-nav>
, all the <nav-*>
sub components are also included, as well all dropdown sub components. Component shorthand aliases (if any) are also included in the plugin. Refer to the component and directive documentation for details.
There are two additional helper plugins for providing the $bvModal
and $bvToast
injections (if you are not using the ModalPlugin
or ToastPlugin
plugins) which are available for import from 'bootstrap-vue'
:
BVModalPlugin
- provides the injection $bvModal
for generating message boxes.BVToastPlugin
- provides the injection $bvToast
for generating on demand toasts.When importing multiple component group and/or directive group plugins, include all imports in a single import
statement for optimal tree shaking.
If you would like to only pull in a specific component or set of components, you can do this by directly importing those components.
To cherry pick a component/directive, start by importing it in the file where it is being used:
// Place all imports from 'bootstrap-vue' in a single import // statement for optimal bundle sizes import { BModal, VBModal } from 'bootstrap-vue'
Then add it to your component definition:
Vue.component('my-component', { components: { 'b-modal': BModal }, directives: { // Note that Vue automatically prefixes directive names with `v-` 'b-modal': VBModal } // ... })
Or register them globally:
Vue.component('b-modal', BModal) // Note that Vue automatically prefixes directive names with `v-` Vue.directive('b-modal', VBModal)
Vue allows for various component and directive name syntaxes here, so feel free to utilize kebab-casing (shown), camelCasing, PascalCasing, and/or object property shorthand (components only).
When using module bundlers, they will usually default to using the esm/
modular build, which has been pre-transpiled by Babel for our supported browsers.
You can override the use of the esm/
build by aliasing 'bootstrap-vue'
to use the BootstrapVue source files, and whitelisting node_modules/bootstrap-vue/src/*
for transpilation by your build process, in your module bundler config. This will allow you to transpile BootstrapVue for your target browsers/environments and potentially reduce bundle sizes (and will only include the babel helper utils once) at the expense of slightly longer build times.
Example webpack.config.js for Babel transpilation:
module.exports = { resolve: { alias: { // Alias for using source of BootstrapVue 'bootstrap-vue$': 'bootstrap-vue/src/index.js' } }, module: { rules: [ { test: /\.js$/, // Exclude transpiling `node_modules`, except `bootstrap-vue/src` exclude: /node_modules\/(?!bootstrap-vue\/src\/)/, use: { loader: 'babel-loader', options: { presets: ['env'] } } } ] } }
You may need to install babel-core
, babel-loader
, and babel-preset-env
:
# If using npm npm install babel-core babel-loader babel-preset-env --save-dev # If using yarn yarn add babel-core babel-loader babel-preset-env --dev
For more details see:
BootstrapVue provides a Nuxt.js module for easily importing BootstrapVue (or portions of BootstrapVue) into your Nuxt.js app.
Nuxt.js version 2.11.0
(or greater) is recommended.
Install dependencies:
# With npm npm install bootstrap-vue # With yarn yarn add bootstrap-vue
Add bootstrap-vue/nuxt
to modules section of your nuxt.config.js
file.
This will include both bootstrap.css
and bootstrap-vue.css
default pre-compiled CSS.
module.exports = { modules: ['bootstrap-vue/nuxt'] }
Note that this will not install the Icons components. To see how to include icons via the Nuxt.js module, refer to the Icons section below.
If you are using custom Bootstrap SCSS, you can disable automatic inclusion of Bootstrap and BootstrapVue pre-compiled CSS files by setting the following option(s) to false
:
module.exports = { modules: ['bootstrap-vue/nuxt'], bootstrapVue: { bootstrapCSS: false, // Or `css: false` bootstrapVueCSS: false // Or `bvCSS: false` } }
BootstrapVue's custom SCSS relies on Bootstrap SCSS variables and mixins, and any variable overrides you may have set. You can include Bootstrap and BootstrapVue SCSS in your project's custom SCSS file:
// Custom Bootstrap variable overrides go first $grid-breakpoints: ( xs: 0, sm: 480px, md: 640px, lg: 992px, xl: 1300px ); $enable-rounded: false; // Then include the following @import 'bootstrap/scss/bootstrap.scss'; @import 'bootstrap-vue/src/index.scss'; // And define any of your custom or additional CSS/SCSS here, // or via an @import
In your app main entry point include the single custom SCSS file (when using sass-loader
):
import 'custom.scss'
transformAssetUrls
with Nuxt.jsThe BootstrapVue Nuxt plugin module will automatically add in the BootstrapVue specific transformAssetUrls
image src
prop configuration for you.
If you wish to reduce your production bundle size because you only use a subset of the available BootstrapVue plugins, you can configure the list of BootstrapVue componentPlugins
or directivePlugins
you want to globally install in your Nuxt.js project. Note tree shaking only applies to the JavaScript code and not CSS/SCSS.
module.exports = { modules: ['bootstrap-vue/nuxt'], bootstrapVue: { componentPlugins: [ 'LayoutPlugin', 'FormPlugin', 'FormCheckboxPlugin', 'FormInputPlugin', 'FormRadioPlugin', 'ToastPlugin', 'ModalPlugin' ], directivePlugins: ['VBPopoverPlugin', 'VBTooltipPlugin', 'VBScrollspyPlugin'] } }
There are two additional helper plugins for providing the $bvModal
and $bvToast
injections (if you are not using the ModalPlugin
or ToastPlugin
plugins) that are available in the componentPlugins
option:
BVModalPlugin
- provides the injection $bvModal
for generating message boxes.BVToastPlugin
- provides the injection $bvToast
for generating on demand toasts.You can also optionally import individual components and/or directives, by configuring the list of BootstrapVue components
or directives
you want to globally install in your Nuxt.js project.
module.exports = { modules: ['bootstrap-vue/nuxt'], bootstrapVue: { components: ['BContainer', 'BRow', 'BCol', 'BFormInput', 'BButton', 'BTable', 'BModal'], directives: ['VBModal', 'VBPopover', 'VBTooltip', 'VBScrollspy'] } }
Feel free to mix and match plugin imports with individual component and directive imports.
Refer to the reference section at the bottom of each of the component and directive docs for details on the plugin names available (and which components and directives are included in each plugin) and component and/or directive import names.
Note that when importing individual components, any component aliases will not be available.
Note: Optimal tree shaking only works when your Nuxt.js app is in production
mode. You may notice larger bundle sizes when not in production
mode (i.e. dev
mode).
If you want to import individual BootstrapVue components into specific pages and/or components of your Nuxt app, you may want to bypass the Nuxt.js module and, instead, follow the module bundlers and Tree shaking with module bundlers sections above. Alternatively you may want to to just import a few plugins (such as LayoutPlugin
) in your Nuxt.js module config, and then import additional components or plugins in the pages where needed.
The icons plugin is not automatically installed when using the Nuxt.js module. You must either explicitly enable the IconsPlugin
, or specify which icon components you wish to import.
All Icons:
module.exports = { modules: ['bootstrap-vue/nuxt'], bootstrapVue: { icons: true // Install the IconsPlugin (in addition to BootStrapVue plugin } }
Specific icons:
module.exports = { modules: ['bootstrap-vue/nuxt'], bootstrapVue: { // Add the desired icon components to the `components` array components: ['BIcon', 'BIconAlertFill', 'BIconCalendar', 'BIconGears'] } }
Icons plugin:
module.exports = { modules: ['bootstrap-vue/nuxt'], bootstrapVue: { // Add the icon plugin to the `componentsPlugins` array componentPlugins: ['IconsPlugin'] } }
If you need to pass a custom BootstrapVue configuration, you may do so by setting the config
property in your nuxt.config.js
:
module.exports = { modules: ['bootstrap-vue/nuxt'], bootstrapVue: { config: { // Custom config options here } } }
Nuxt.js module uses the pre-transpiled versions of BootstrapVue for faster development builds and the source (src/
) of BootstrapVue for higher quality and smaller production builds.
You can override this option using usePretranspiled
option. Setting to true
always uses the pre-transpiled versions, while setting it to false
will always use src/
. By default usePretranspiled
is enabled in development mode only. You should not need to use this option as the default is most optimal for performance.
Unlike V2, Vue CLI 3 doesn't use templates.
Create a new project in the directory my-project
:
npx @vue/cli create my-project
Enter the my-project
directory and install bootstrap-vue
:
npm install bootstrap-vue
Under the hood, Vue CLI uses webpack, so we can register the BootstrapVue plugin as with the webpack instructions.
import Vue from 'vue' import { BootstrapVue, BootstrapVueIcons } from 'bootstrap-vue' import 'bootstrap/dist/css/bootstrap.css' import 'bootstrap-vue/dist/bootstrap-vue.css' Vue.use(BootstrapVue) Vue.use(BootstrapVueIcons)
For additional configuration for Vue CLI 3 for using project relative paths for image src props on various BootstrapVue components, refer to the Vue CLI 3 section of the Image Src Resolving reference page.
As an alternative, you can use the Bootstrap-Vue Vue CLI 3 plugin to help you configure your app.
vue create my-app cd my-app vue add bootstrap-vue
This will create a new app with basic BootstrapVue settings to get your project started.
In the future this plugin will provide options for more advanced configurations and templates.
For Icons support, you may need to edit the resultant config file.
If not using a module bundler or compile process, you can instead add the Bootstrap and BootstrapVue CSS URLs in your HTML <head>
section, followed by the required JavaScript files.
When supporting older browsers (see Browser Support below), you will need to include a polyfill for handling modern JavaScript features before loading Vue and BootstrapVue JavaScript files.
<!-- Add this to <head> --> <!-- Load required Bootstrap and BootstrapVue CSS --> <link type="text/css" rel="stylesheet" href="//unpkg.com/bootstrap/dist/css/bootstrap.min.css" /> <link type="text/css" rel="stylesheet" href="//unpkg.com/bootstrap-vue@latest/dist/bootstrap-vue.min.css" /> <!-- Load polyfills to support older browsers --> <script src="//polyfill.io/v3/polyfill.min.js?features=es2015%2CIntersectionObserver" crossorigin="anonymous"></script> <!-- Load Vue followed by BootstrapVue --> <script src="//unpkg.com/vue@latest/dist/vue.min.js"></script> <script src="//unpkg.com/bootstrap-vue@latest/dist/bootstrap-vue.min.js"></script> <!-- Load the following for BootstrapVueIcons support --> <script src="//unpkg.com/bootstrap-vue@latest/dist/bootstrap-vue-icons.min.js"></script>
Choosing the best variant for your build environment / packager helps reduce bundle sizes. If your bundler supports esm modules, it will automatically prefer it over commonjs.
Variant | Environments | Tree Shake | Package path |
---|---|---|---|
ESM module | webpack 2+ / rollup.js | Yes | esm/index.js |
ESM bundle | webpack 2+ / rollup.js | Yes | dist/bootstrap-vue.esm.js |
commonjs2 | webpack 1 / ... | No | dist/bootstrap-vue.common.js or dist/bootstrap-vue.common.min.js |
UMD | Browser | No | dist/bootstrap-vue.js or dist/bootstrap-vue.min.js |
Note the UMD (browser) variant does not include BootstrapVue icons support. All other variants listed above do include the BootstrapVueIcons
(IconsPlugin
) plugin (note the icons plugin is not automatically installed, and must explicitly installed via Vue.use()
. See the Icons usage section for more details.
Icons only modules:
Variant | Environments | Tree Shake | Package path |
---|---|---|---|
ESM bundle | webpack 2+ / rollup.js | Yes | dist/bootstrap-vue-icons.esm.js |
commonjs2 | webpack 1 / ... | No | dist/bootstrap-vue-icons.common.js or dist/bootstrap-vue-icons.common.min.js |
UMD | Browser | No | dist/bootstrap-vue-icons.js or dist/bootstrap-vue-icons.min.js |
The ESM
module build and the ESM
bundles (single file) are tree-shakeable, but you will experience smaller final bundle sizes when using the ESM
module vs. the ESM
bundle.
All of the build variants listed above have been pre-transpiled targeting the browsers supported by BootstrapVue. However, if you are targeting only modern browsers, you may want to import BootstrapVue
from src/index.js
, (by aliasing bootstrap-vue
to bootstrap-vue/src/index.js
) and whitelisting bootstrap-vue/src
for transpilation via your own project. This can potentially reduce final project bundle sizes. See the Using BootstrapVue source code for smaller bundles section above for more details.
BootstrapVue relies on Popper.js
(for Tooltip, Popover, and Dropdown positioning), PortalVue
(for toasts) and vue-functional-data-merge
(used by our functional components). These three dependencies are included in the BootstrapVue UMD
bundle, while the UMD (browser) icons only bundle includes vue-functional-data-merge
.
If you've already been using Bootstrap v4, there are a couple adjustments you may need to make to your project:
bootstrap.js
file from your page scripts or build pipelinejQuery
, you can safely remove it — BootstrapVue does not depend on jQuery
BootstrapVue is to be used with Bootstrap v4.4 CSS/SCSS. Please see Browsers and devices for more information about browsers currently supported by Bootstrap v4.
BootstrapVue is written in Vue.js! So it is up to your project and bundler which browsers are supported.
Following features and APIs are used by BootstrapVue:
Array.from()
, Array.isArray()
, Object.assign()
, Object.is()
, etc.)Promise
MutationObserver
IntersectionObserver
(optional)If you want to support older IE, Android, and iOS device web browsers, you may want to use core-js and intersection-observer:
npm install core-js regenerator-runtime intersection-observer
Then import the polyfills in your app main entry point:
import 'core-js/stable' import 'regenerator-runtime/runtime' import 'intersection-observer' // Optional import Vue from 'vue' import BootstrapVue from 'bootstrap-vue'
If using deprecated @babel/polyfill:
npm install @babel/polyfill intersection-observer
Then import the polyfills in your app main entry point:
import '@babel/polyfill' import 'intersection-observer' // Optional import Vue from 'vue' import BootstrapVue from 'bootstrap-vue'
Alternatively, use Polyfill.io to dynamically serve browser specific polyfills via <script>
tags in the HTML <head>
section. See the Browser section above for an example.
BootstrapVue provides additional helper files for auto completion in popular IDE editors.
If you are using VS Code as your text editor, BootstrapVue has intellisense autocompletion for component attributes and directives available via the dist/vetur-tags.json
and dist/vetur-attributes.json
files.
For WebStorm editor (or web-types compatible), BootstrapVue provides the file dist/web-types.json
for component attribute and directive auto-completion.
