• examples/advanced/composables.md - Using composables (useToast, useModal)

3. Follow the specific instructions in that example file for syntax, structure, and best practices

Important Notes:

• All examples follow Bootstrap Vue 3.0 API (Vue 3 + Bootstrap 5)
• Examples use Composition API syntax
• Each example file includes key concepts, code examples, and key points
• Always check the example file for best practices and common patterns

4. Reference API documentation in the api/ directory when needed:

Components (组件):

• See component files in examples/components/ → https://bootstrap-vue.org/docs/components

Examples and Templates

This skill includes detailed examples organized to match the official documentation structure. All examples are in the examples/ directory (see mapping above).

To use examples:

• Identify the topic from the user's request
• Load the appropriate example file from the mapping above
• Follow the instructions, syntax, and best practices in that file
• Adapt the code examples to your specific use case

To use templates:

• Reference templates in templates/ directory for common scaffolding
• Adapt templates to your specific needs and coding style

API Reference

• Component types and interfaces

Directives API (api/directives.md)

• Directive syntax and usage
• Directive modifiers
• Directive options

Composables API (api/composables.md)

• useToast composable
• useModal composable
• usePopover composable

To use API reference: 1. Identify the API you need help with 2. Load the corresponding API file from the api/ directory 3. Find the API signature, parameters, return type, and examples 4. Reference the linked example files for detailed usage patterns 5. All API files include links to relevant example files in the examples/ directory

Best Practices

1. Import Bootstrap CSS: Import Bootstrap CSS in your entry file 2. Use Composition API: Prefer Composition API for Vue 3 projects 3. Tree-shaking: Import components individually for better tree-shaking 4. Responsive design: Use Bootstrap grid system for responsive layouts 5. Accessibility: Follow Bootstrap accessibility guidelines 6. Theme customization: Use Bootstrap variables for consistent theming 7. Directives: Use directives for programmatic component control 8. Composables: Use composables for programmatic API access 9. Component composition: Compose components for complex UIs 10. Performance: Optimize bundle size with tree-shaking

<script setup>
import { ref, computed } from 'vue'
import { BForm, BFormGroup, BFormInput, BButton } from 'bootstrap-vue-next'

const form = ref({
  email: '',
  password: ''
})

const emailState = computed(() => {
  return form.value.email.length > 0 && form.value.email.includes('@')
})

const emailFeedback = computed(() => {
  return emailState.value ? '' : 'Please enter a valid email'
})

const passwordState = computed(() => {
  return form.value.password.length >= 6
})

const passwordFeedback = computed(() => {
  return passwordState.value ? '' : 'Password must be at least 6 characters'
})

const onSubmit = () => {
  if (emailState.value && passwordState.value) {
    console.log('Form submitted:', form.value)
  }
}
</script>

Example: Form with Select

<template>
  <BForm>
    <BFormGroup label="Select" label-for="select">

Example: Form Input

<template>
  <BFormInput
    v-model="value"
    placeholder="Enter text"
  />
</template>

<script setup>
import { ref } from 'vue'
import { BFormInput } from 'bootstrap-vue-next'

const value = ref('')
</script>

Example: Multiple Components

<template>
  <BCard title="Example Card">
    <BFormInput v-model="value" placeholder="Enter text" />
    <BButton variant="primary" class="mt-3">Submit</BButton>
  </BCard>
</template>

<script setup>
import { ref } from 'vue'
import { BCard, BFormInput, BButton } from 'bootstrap-vue-next'

const value = ref('')
</script>

Key Points

• Import components from 'bootstrap-vue-next'
• Use component props to configure behavior
• Use v-model for two-way binding
• Use @click for event handling
• Use Composition API with script setup
• Components follow Bootstrap 5 styling

Instructions

This example demonstrates how to install Bootstrap Vue 3.0 and set it up in a Vue 3 project.

Key Concepts

• Installing Bootstrap Vue
• Importing Bootstrap CSS
• Registering components
• Basic setup

Example: Installation

# Using npm
npm install bootstrap-vue-next bootstrap

# Using yarn
yarn add bootstrap-vue-next bootstrap

# Using pnpm
pnpm add bootstrap-vue-next bootstrap

Example: Import Bootstrap CSS

// In main.js or main.ts
import 'bootstrap/dist/css/bootstrap.css'

Example: Basic Setup

// main.js
import { createApp } from 'vue'
import App from './App.vue'
import BootstrapVue3 from 'bootstrap-vue-next'
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue-next/dist/bootstrap-vue-next.css'

const app = createApp(App)
app.use(BootstrapVue3)
app.mount('#app')

Example: Tree-shaking Setup

// main.js
import { createApp } from 'vue'
import App from './App.vue'
import { BButton, BFormInput } from 'bootstrap-vue-next'
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue-next/dist/bootstrap-vue-next.css'

const app = createApp(App)
app.component('BButton', BButton)
app.component('BFormInput', BFormInput)
app.mount('#app')

Example: TypeScript Setup

// main.ts
import { createApp } from 'vue'
import App from './App.vue'
import BootstrapVue3 from 'bootstrap-vue-next'
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue-next/dist/bootstrap-vue-next.css'

const app = createApp(App)
app.use(BootstrapVue3)
app.mount('#app')

Key Points

• Install bootstrap-vue-next and bootstrap packages
• Import Bootstrap CSS in entry file
• Use app.use(BootstrapVue3) for global registration
• Or register components individually for tree-shaking
• Works with both JavaScript and TypeScript
• Requires Vue 3 and Bootstrap 5

Component Template | 组件模板

Basic Component Usage

<template>
  <BComponentName
    prop1="value1"
    prop2="value2"
    @event="handleEvent"
  />
</template>

<script setup>
import { BComponentName } from 'bootstrap-vue-next'

const handleEvent = () => {
  console.log('Event handled')
}
</script>

Component with v-model

<template>
  <BFormInput
    v-model="value"
    placeholder="Enter text"
  />
</template>

<script setup>
import { ref } from 'vue'
import { BFormInput } from 'bootstrap-vue-next'

const value = ref('')
</script>

Component in Form

<template>
  <BForm @submit.prevent="onSubmit">
    <BFormGroup label="Field" label-for="field">
      <BFormInput
        id="field"
        v-model="form.field"
        required
      />
    </BFormGroup>
    <BButton type="submit" variant="primary">Submit</BButton>
  </BForm>
</template>

<script setup>
import { ref } from 'vue'
import { BForm, BFormGroup, BFormInput, BButton } from 'bootstrap-vue-next'

const form = ref({
  field: ''
})

const onSubmit = () => {
  console.log('Form submitted:', form.value)
}
</script>

Project Setup Template | 项目设置模板

Basic Vue 3 + Bootstrap Vue Setup

// package.json
{
  "dependencies": {
    "vue": "^3.0.0",
    "bootstrap-vue-next": "^0.0.0",
    "bootstrap": "^5.0.0"
  }
}

// main.js
import { createApp } from 'vue'
import App from './App.vue'
import BootstrapVue3 from 'bootstrap-vue-next'
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue-next/dist/bootstrap-vue-next.css'

const app = createApp(App)
app.use(BootstrapVue3)
app.mount('#app')

<!-- App.vue -->
<template>
  <BContainer>
    <BRow>
      <BCol>
        <h1>Bootstrap Vue App</h1>
      </BCol>
    </BRow>
  </BContainer>
</template>

<script setup>
import { BContainer, BRow, BCol } from 'bootstrap-vue-next'
</script>

With TypeScript

// main.ts
import { createApp } from 'vue'
import App from './App.vue'
import BootstrapVue3 from 'bootstrap-vue-next'
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue-next/dist/bootstrap-vue-next.css'

const app = createApp(App)
app.use(BootstrapVue3)
app.mount('#app')

<!-- App.vue -->
<template>
  <BContainer>
    <BRow>
      <BCol>
        <h1>Bootstrap Vue App</h1>
      </BCol>
    </BRow>
  </BContainer>
</template>

<script setup lang="ts">
import { BContainer, BRow, BCol } from 'bootstrap-vue-next'
</script>

With Tree-shaking

// main.js
import { createApp } from 'vue'
import App from './App.vue'
import { BButton, BFormInput, BContainer, BRow, BCol } from 'bootstrap-vue-next'
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue-next/dist/bootstrap-vue-next.css'

const app = createApp(App)
app.component('BButton', BButton)
app.component('BFormInput', BFormInput)
app.component('BContainer', BContainer)
app.component('BRow', BRow)
app.component('BCol', BCol)
app.mount('#app')
