What is markstream-angular?

A setup guide for adding the alpha Markstream Markdown renderer to Angular 20 or newer applications. It covers standalone components, signals, CSS, optional integrations, and gradually streamed content.

Use it when integrating Markstream into an Angular app, including an AI chat interface. It helps configure Markdown content, animation settings, math styles, custom HTML tags, and standalone component imports.

It helps avoid mixing incompatible Angular versions or adding optional packages unnecessarily. It also explains how streaming chat output should differ from already-complete conversation history.

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	$0.00053	$0.00727
Opus 5.5	$0.00021	$0.00291

Security

Grade A, and why

markstream-angular 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 Angular

Use this skill when the host app is Angular and the task is to adopt the Angular package cleanly.

Workflow

Confirm the repo is Angular 20 or newer and accepts an alpha renderer API.
Install markstream-angular plus only the requested optional peers.
Import markstream-angular/index.css from the app shell.
- Add katex/dist/katex.min.css when math is enabled.
Prefer standalone Angular integration.
- Use MarkstreamAngularComponent in imports and keep examples signal-friendly.
Start with [content].
- For streaming AI chat, keep [content] and use built-in smooth streaming first.
  - [smoothStreaming]="'auto'" is the default and activates when [typewriter]="true" or [maxLiveNodes]="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 component starts streaming and later switches to history when [final]="true".
  - Streaming: [smoothStreaming]="'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: [smoothStreaming]="false", [fade]="true", [typewriter]="false". Content is already complete — pacing would slow it down, but fade gives a polished entry animation.
  - Dynamic switch: [smoothStreaming]="isStreaming ? 'auto' : false", [fade]="!isStreaming".
- Use [final] for end-of-stream state; final parsing is gated until visible content catches up when smooth streaming is active.
- Move to nodes + final only for worker-preparsed content, shared AST stores, or custom AST control.
- Remember that [htmlPolicy] now defaults to 'safe', and Mermaid strict mode is on by default through [mermaidProps].
Use [customHtmlTags] and [customComponents] for trusted tag workflows.
Validate with the smallest useful Angular 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.
