Markstream Vue 2 Vite

Use this skill when the host app is Vue 2 and the bundler is Vite.

Workflow

1. Confirm the repo is Vue 2 with Vite-based tooling.
2. Install markstream-vue2 plus only the requested optional peers.
3. Import markstream-vue2/index.css after resets.
4. Use Vite worker imports when the repo needs bundled workers.
   • markstream-vue2/workers/... ?worker or ?worker&inline patterns are allowed here.
5. Keep Composition API decisions explicit for Vue 2.6 repos.
   • For AI chat or streaming UIs, keep content and use built-in smooth streaming first.
     • smooth-streaming="auto" is the default and activates when typewriter=true or max-live-nodes <= 0.
     • typewriter only controls the blinking cursor and defaults to false.
     • fade controls node enter and streamed-text fade animations and defaults to true.
   • Streaming vs recovering history: in chat UIs the same MarkdownRender starts streaming and later switches to history when final=true.
     • Streaming: smooth-streaming="auto", :fade="false", typewriter=true. This is a conservative visual/performance choice, not an API incompatibility. This adapter has not adopted Vue 3's bounded append fades, so verify its animation behavior before enabling both.
     • Recovering history: :smooth-streaming="false", :fade="true", typewriter=false. Content is already complete — pacing would slow it down, but fade gives a polished entry animation.
     • Dynamic switch: :smooth-streaming="isStreaming ? 'auto' : false", :fade="!isStreaming".
   • Move to nodes + final only for worker-preparsed content, shared AST stores, or custom AST control.
   • Remember that html-policy now defaults to safe, and Mermaid strict mode is on by default through mermaid-props.
6. Validate with the smallest useful Vite dev or build command.

Default Decisions

• Prefer bundled workers over CDN workers in Vite-based Vue 2 repos.
• Keep UnoCSS or Tailwind resets before Markstream CSS.
• Use the generic markstream-vue2 skill only when the bundler-specific choice does not matter.
• Keep html-policy="safe" and Mermaid strict mode unless the task is preserving trusted legacy rendering.
• If a trusted surface needs older behavior, use html-policy="trusted" and :mermaid-props="{ isStrict: false }" only on that surface and explain why.
