Basic Component

Create components/Counter.vue:

<script setup>
import { ref } from 'vue'

const props = defineProps({
  start: {
    type: Number,
    default: 0
  }
})

const count = ref(props.start)
</script>

<template>
  <div class="counter">
    <button @click="count--">-</button>
    <span class="count">{{ count }}</span>
    <button @click="count++">+</button>
  </div>
</template>

<style scoped>
.counter {
  display: flex;
  align-items: center;
  gap: 1rem;
}
button {
  padding: 0.5rem 1rem;
  font-size: 1.5rem;
  cursor: pointer;
}
.count {
  font-size: 2rem;
  min-width: 3rem;
  text-align: center;
}
</style>

Usage:

# Interactive Counter

<Counter :start="10" />

Component with Slots

<!-- components/Card.vue -->
<script setup>
defineProps({
  title: String,
  color: {
    type: String,
    default: 'blue'
  }
})
</script>

<template>
  <div :class="`card card-${color}`">
    <h3 v-if="title">{{ title }}</h3>
    <slot />
  </div>
</template>

<style scoped>
.card {
  padding: 1.5rem;
  border-radius: 0.5rem;
  margin: 1rem 0;
}
.card-blue { background: #3b82f6; color: white; }
.card-green { background: #22c55e; color: white; }
.card-red { background: #ef4444; color: white; }
</style>

Usage:

<Card title="Important" color="red">
  This is a red card with important content.
</Card>

Component with Slidev Context

<!-- components/ProgressBar.vue -->
<script setup>
import { computed } from 'vue'
import { useNav } from '@slidev/client'

const { currentSlideNo, total } = useNav()

const progress = computed(() =>
  (currentSlideNo.value / total.value) * 100
)
</script>

<template>
  <div class="progress-bar">
    <div
      class="progress"
      :style="{ width: `${progress}%` }"
    />
  </div>
</template>

<style scoped>
.progress-bar {
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  height: 4px;
  background: #e5e7eb;
}
.progress {
  height: 100%;
  background: #3b82f6;
  transition: width 0.3s;
}
</style>

Code Demo Component

<!-- components/CodeDemo.vue -->
<script setup>
import { ref, computed } from 'vue'

const props = defineProps({
  code: String,
  language: {
    type: String,
    default: 'javascript'
  }
})

const output = ref('')
const error = ref('')

const run = () => {
  try {
    output.value = eval(props.code)
    error.value = ''
  } catch (e) {
    error.value = e.message
    output.value = ''
  }
}
</script>

<template>
  <div class="code-demo">
    <pre><code>{{ code }}</code></pre>
    <button @click="run">Run</button>
    <div v-if="output" class="output">{{ output }}</div>
    <div v-if="error" class="error">{{ error }}</div>
  </div>
</template>

Composables

useNav

Access navigation state:

<script setup>
import { useNav } from '@slidev/client'

const {
  currentSlideNo,  // Current slide number
  total,           // Total slides
  next,            // Go to next
  prev,            // Go to previous
  go               // Go to specific slide
} = useNav()
</script>

useSlideContext

Access slide context:

<script setup>
import { useSlideContext } from '@slidev/client'

const {
  $slidev,         // Global context
  $clicks,         // Current click count
  $page            // Current page number
} = useSlideContext()
</script>

Global Components

global-top.vue

Appears above all slides:

<!-- global-top.vue -->
<template>
  <div class="absolute top-4 right-4">
    <img src="/logo.png" class="h-8" />
  </div>
</template>

global-bottom.vue

Appears below all slides:

<!-- global-bottom.vue -->
<template>
  <footer class="absolute bottom-4 left-4 text-sm opacity-50">
    © 2025 My Company
  </footer>
</template>

Component Patterns

Progress Indicator

<div class="fixed bottom-4 right-4 text-sm">
  <SlideCurrentNo /> / <SlidesTotal />
</div>

Social Links

<!-- components/SocialLinks.vue -->
<template>
  <div class="flex gap-4">
    <a href="https://twitter.com/..." target="_blank">
      <carbon-logo-twitter class="text-2xl" />
    </a>
    <a href="https://github.com/..." target="_blank">
      <carbon-logo-github class="text-2xl" />
    </a>
  </div>
</template>

QR Code

<!-- components/QRCode.vue -->
<script setup>
import { ref, onMounted } from 'vue'
import QRCodeLib from 'qrcode'

const props = defineProps({
  url: String,
  size: { type: Number, default: 200 }
})

const qrDataUrl = ref('')

onMounted(async () => {
  qrDataUrl.value = await QRCodeLib.toDataURL(props.url, {
    width: props.size
  })
})
</script>

<template>
  <img :src="qrDataUrl" :width="size" :height="size" />
</template>

Best Practices

1. Keep Components Simple: Focus on single responsibilities
2. Use Props: Make components configurable
3. Style Scoped: Avoid global style pollution
4. Document Usage: Add comments showing how to use
5. Test Interactivity: Verify components work in presenter mode

Output Format

When creating components, provide:

COMPONENT: [name]
PURPOSE: [what it does]

FILE: components/[Name].vue
---
<script setup>
[script content]
</script>

<template>
[template content]
</template>

<style scoped>
[styles]
</style>
---

USAGE IN SLIDES:
```markdown
<[Name] prop="value" />
