Global Layers

Available since v0.17

Global layers allow you to have custom components that persist across slides. This could be useful for having footers, cross-slide animations, global effects, etc.

Slidev provides three layers for this usage, create global-top.vue, global-bottom.vue or custom-nav-controls.vue under your project root and it will pick up automatically.

Layers relationship:

• Global Top (global-top.vue)
• Slides
• Global Bottom (global-bottom.vue)
• NavControls
  • Customized Navigation Controls (custom-nav-controls.vue)

Example

<!-- global-bottom.vue -->
<template>
  <footer class="absolute bottom-0 left-0 right-0 p-2">Your Name</footer>
</template>

The text Your Name will appear on all your slides.

<!-- custom-nav-controls -->
<template>
  <button class="icon-btn" title="Next" @click="$slidev.nav.next">
    <carbon:arrow-right />
  </button>
</template>

The button Next will appear in NavControls.

To enable it conditionally, you can apply it with the Vue Global Context.

<!-- hide the footer from Page 4 -->
<template>
  <footer
    v-if="$slidev.nav.currentPage !== 4"
    class="absolute bottom-0 left-0 right-0 p-2"
  >
    Your Name
  </footer>
</template>

<!-- hide the footer from "cover" layout -->
<template>
  <footer
    v-if="$slidev.nav.currentLayout !== 'cover'"
    class="absolute bottom-0 left-0 right-0 p-2"
  >
    Your Name
  </footer>
</template>

<!-- an example footer for pages -->
<template>
  <footer
    v-if="$slidev.nav.currentLayout !== 'cover'"
    class="absolute bottom-0 left-0 right-0 p-2"
  >
    {{ $slidev.nav.currentPage }} / {{ $slidev.nav.total }}
  </footer>
</template>

<!-- custom-nav-controls -->
<!-- hide the button in Presenter model -->
<template>
  <button v-if="!$slidev.nav.isPresenter" class="icon-btn" title="Next" @click="$slidev.nav.next">
    <carbon:arrow-right />
  </button>
</template>
