Preview is a UI feedback tool built on top Vite.

Features

• Render any component in a sandbox environment
• Responsive previews of a component
• Use <preview> blocks as unit test fixtures/examples

Getting Started

VS Code

• When editor is focused on a .vue file, you can
  • Run Preview: Show preview command
  • Click on button on editor tab.

Vite

• Install @vuedx/preview as dev dependency

Guide

Defining Previews

Use <preview> custom block to define previews. e.g.

<script setup>
const props = defineProps({
  type: String,
});
</script>

<template>
  <button :class="type">
    <slot />
  </button>
</template>

<preview name="Primary">
  <Button type="primary">Primary Button</Button>
</preview>

<preview name="Secondary">
  <Button type="secondary">Secondary Button</Button>
</preview>

We try to generate previews when no <preview> blocks are defined. However, the automatic generation is trivial and only works for simpler cases for now.

We are exploring automatic generation using static code analysis, and active looking for feedback. You can help us by creating issues when generated preview is not helpful or any suggestions that might improve previews.

Mocking HTTP Requests

Delayed response

Use $p.http.delayed() helper to stub a delayed response.

<preview>
  <setup 
    :requests="{
      '/response/delayed': $p.http.delayed(1000)
    }"
  />
</preview>

Known Limitations

1. Using <preview> blocks could create noise and editor tools like "search in all files" would be difficult to use. We want to explore alternative to <preview> block:
   • Using .preview file next to .vue file using same SFC-like structure
