What is markstream-vue2-cli?

An integration guide for adding markstream-vue2 to Vue 2 applications built with Vue CLI or Webpack 4. It covers compatible styling, worker fallbacks, code-block choices, and streaming behavior.

Use it to configure markstream-vue2, import its CSS, connect Mermaid or KaTeX workers through a CDN, choose supported code blocks, and set up smooth streaming in chat interfaces.

It avoids setup that only works with newer build tools, such as Vite worker imports, and clarifies which renderer options are available in older Vue projects.

About the project

markstream-vue is a family of Markdown renderers that display AI-generated text while it is still arriving, including unfinished formatting, code blocks, diagrams, and mathematical notation. It is for AI chat interfaces built with Vue and other supported frameworks, with markstream-vue targeting Vue 3, Nuxt, and VitePress. The catalogue entries provide agent guidance for using the renderer family.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00083	$0.00808
Opus 5.5	$0.00033	$0.00323
Sonnet 5.5	$0.00017	$0.00162
Haiku 4.5	$0.00008	$0.00081

Security

Grade A, and why

markstream-vue2-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Markstream Vue 2 CLI

Use this skill when the host app is Vue 2 on Vue CLI or another Webpack 4-style stack.

Workflow

Confirm the repo uses Vue 2 plus Vue CLI or Webpack 4-era tooling.
Install markstream-vue2 and only the peers required for the requested features.
Import markstream-vue2/dist/index.css in the app shell.
Avoid Vite-style ?worker imports.
- Use createKaTeXWorkerFromCDN(...) and createMermaidWorkerFromCDN(...) when workers are needed.
Prefer stable code block defaults over brittle wiring.
- In Webpack 4-era repos, stream-diffs (or plain <pre>) is the only code block runtime — there is no Monaco/stream-monaco fallback and no MarkdownCodeBlockNode.
- Use top-level code-block-options or direct CodeBlockNode.code-block-options for the shared renderer-neutral option contract. Keep header/toolbar props in code-block-props.
- 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.
Validate with the smallest useful local dev or build command.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
