draft of BApp #2732

BApp Component

The BApp component is the new recommended way to configure bootstrap-vue-next. It replaces the plugin-based approach and provides better defaults management and orchestrator integration.

Features

Defaults Management: Inject and merge component defaults throughout your application
Orchestrator Integration: Automatically includes Modal, Toast, and Popover orchestrators
Plugin Compatibility: Works alongside existing plugins for backward compatibility
Type Safety: Full TypeScript support with proper type inference
RTL Support: Built-in right-to-left language support
Flexible Teleporting: Control where orchestrators are rendered in the DOM

Basic Usage

<template>
  <BApp>
    <!-- Your application content -->
    <router-view />
  </BApp>
</template>

<script setup lang="ts">
import {BApp} from 'bootstrap-vue-next'
</script>

Configuration

Setting Component Defaults

<template>
  <BApp :defaults="appDefaults">
    <!-- Your application content -->
  </BApp>
</template>

<script setup lang="ts">
import {BApp} from 'bootstrap-vue-next'

const appDefaults = {
  BButton: {
    variant: 'primary',
    size: 'sm',
  },
  BModal: {
    centered: true,
    noCloseOnBackdrop: true,
  },
  BToast: {
    variant: 'success',
    solid: true,
  },
}
</script>

Advanced Defaults Configuration

<template>
  <BApp :defaults="appDefaults" :merge-defaults="true" :deep-merge="true">
    <!-- Your application content -->
  </BApp>
</template>

<script setup lang="ts">
import {BApp} from 'bootstrap-vue-next'

const appDefaults = {
  BButton: {
    variant: 'primary',
    size: 'sm',
  },
}
</script>

Orchestrator Configuration

<template>
  <BApp :teleport-to="'body'" :append-toast="true">
    <!-- Your application content -->
  </BApp>
</template>

Disabling Orchestrators

<template>
  <BApp :no-modals="true" :no-toasts="true" :no-popovers="true">
    <!-- Your application content -->
  </BApp>
</template>

RTL Configuration

<template>
  <BApp :rtl="rtlConfig">
    <!-- Your application content -->
  </BApp>
</template>

<script setup lang="ts">
import {BApp} from 'bootstrap-vue-next'

const rtlConfig = {
  rtlInitial: true,
  localeInitial: 'ar',
}
</script>

Migration from Plugins

Before (Plugin-based)

import {createApp} from 'vue'
import {createBootstrap} from 'bootstrap-vue-next'

const app = createApp(App)

app.use(
  createBootstrap({
    components: {
      BButton: {
        variant: 'primary',
      },
    },
  })
)

After (BApp-based)

<template>
  <BApp :defaults="{BButton: {variant: 'primary'}}">
    <App />
  </BApp>
</template>

<script setup lang="ts">
import {BApp} from 'bootstrap-vue-next'
import App from './App.vue'
</script>

Props

Prop	Type	Default	Description
`defaults`	`Partial<BvnComponentProps>`	`undefined`	Component defaults to apply globally
`mergeDefaults`	`boolean`	`false`	Whether to merge with existing defaults
`deepMerge`	`boolean`	`false`	Whether to perform deep merge of nested objects
`teleportTo`	`TeleportProps['to']`	`undefined`	Where to teleport the orchestrator container
`noModals`	`boolean`	`false`	Whether to disable modal orchestrator
`noToasts`	`boolean`	`false`	Whether to disable toast orchestrator
`noPopovers`	`boolean`	`false`	Whether to disable popover orchestrator
`noOrchestrator`	`boolean`	`false`	Whether to disable all orchestrators
`appendToast`	`boolean`	`false`	Whether new toasts should be appended to the list
`inhert`	`boolean`	`false`	Whether to inherit parent orchestrator controllers
`rtl`	`boolean \| RTLConfig`	`false`	RTL configuration object or boolean

RTL Configuration Object

interface RTLConfig {
  rtlInitial: boolean // Initial RTL state
  localeInitial?: string // Initial locale
}

Composables

When using BApp, the following composables work without requiring plugin installation:

useToastController() - Create and manage toasts programmatically
useModalController() - Create and manage modals programmatically
usePopoverController() - Create and manage popovers programmatically

Internal Features

The BApp component automatically provides several internal services:

Show/Hide Registry: Global registry for show/hide components
Modal Manager: Stack management for multiple modals
Breadcrumb Service: Global breadcrumb item management
RTL Service: Right-to-left text direction support

Default Merging Behavior

The component supports three modes for handling defaults:

Replace Mode (default): defaults prop completely replaces any existing defaults
Merge Mode (mergeDefaults: true): Shallow merge with existing defaults
Deep Merge Mode (mergeDefaults: true, deepMerge: true): Deep merge nested objects

Teleporting

By default, orchestrators render inline. Use teleportTo to render them elsewhere:

<template>
  <BApp teleport-to="body">
    <!-- Orchestrators will render in document.body -->
  </BApp>
</template>

Backward Compatibility

The BApp component is fully backward compatible with existing plugin-based setups. You can gradually migrate by:

Adding BApp to your root component
Moving defaults from plugin configuration to BApp props
Removing plugin installations once migration is complete

The plugins will show deprecation warnings but continue to work until removed in a future version.

Notes

Only one BApp or orchestrator should be active at a time per application
The component uses Vue's provide/inject system for dependency injection
All orchestrators are automatically teleported when teleportTo is specified
The component inherits all attributes and passes them to the default slot

@xvaara, I really like this for the core setup. It's what I would use in my app, given a choice between this and the current plugin.

The main question I have is about tree shaking. As @VividLemon mentioned previously, there is some segment of our user base that is quite concerned about the deployed size of BSVN. If we eventually deprecate the plugins and only allow this method of installation, do we effectively disable tree shaking?

I think the best solution to this is to effectively give people the tools to build their own "bapp" and document how to do it well

+  teleportTo: undefined,
+  defaults: undefined,
+  mergeDefaults: false,
+  deepMerge: false,


Maybe mergeDefaults is boolean | function to where the function is the algorithm to use for merging?

I generally dislike props that just effect the behavior of other props. Begs the question why it's not just an object
