markstream-vue2

Development
View on GitHub

Integrate markstream-vue2 into a Vue 2.6 or 2.7 app. Use when Codex needs Vue 2-compatible setup, `@vue/composition-api` decisions, CSS wiring, optional peer setup, or scoped Markstream overrides in a Vue 2 repository that is not specifically Vue CLI / Webpack 4 constrained.

Markstream Vue 2

Use this skill when the host app is Vue 2 and not specifically a Vue CLI / Webpack 4 edge case.

Workflow

  1. Confirm the repo is Vue 2.6 or 2.7.
  2. Install markstream-vue2.
    • Add @vue/composition-api only when the repo is Vue 2.6 and uses Composition API patterns.
  3. Import markstream-vue2/index.css after resets.
  4. Start with <MarkdownRender :content="markdown" />.
    • 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. Smooth pacing handles gradual appearance; fade would flicker.
      • 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.
  5. Use scoped custom component mappings when the task needs overrides or trusted tags.
  6. Validate with the smallest useful dev or build command.

Default Decisions

  • Vue 2.7 can use built-in Composition API support.
  • Vue 2.6 needs @vue/composition-api only when the codebase actually relies on Composition API.
  • If the repo is Vue CLI / Webpack 4, prefer markstream-vue2-cli.
  • If the repo is Vue 2 plus Vite worker imports, prefer markstream-vue2-vite.
  • 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.
