Markstream Vue 2 CLI

Overview

Handle Vue CLI and Webpack 4 constraints that differ materially from modern Vue 2/Vite setup.

When to Use

Use when Vue 2 runs on Vue CLI or Webpack 4 and package export maps or Vite worker imports are unavailable.

Workflow

Before changing dependencies or source files, inspect the existing package manager and project conventions, preview the intended edits, and obtain explicit user approval.

1. Confirm Vue 2 plus Vue CLI/Webpack 4.
2. Install markstream-vue2 and only requested peers.
3. Import markstream-vue2/dist/index.css, because legacy tooling may not understand the CSS export map.
4. Avoid ?worker imports. Use Markstream CDN worker helpers for KaTeX or Mermaid only when needed.
5. Prefer stream-markdown code blocks over fragile Monaco worker wiring.
6. Keep content with smooth streaming for chat; set final and disable pacing/cursor for completed history.
7. Keep HTML safe and Mermaid strict; validate the actual legacy build.

Example

vue
<script>
import MarkdownRender from 'markstream-vue2'
// Legacy Webpack may not resolve the package CSS export map.
import 'markstream-vue2/dist/index.css'

export default {
  components: { MarkdownRender },
  data: () => ({ content: '# Answer', done: false }),
}
</script>

<template>
  <MarkdownRender
    :content="content"
    :final="done"
    :fade="false"
  />
</template>

Limitations

• CDN workers require network access and compatible content-security policy.
• Monaco-style worker setups are intentionally not covered.
• Vue 2.6 may also require @vue/composition-api.

Security & Safety Notes

Do not introduce CDN workers without reviewing CSP, network policy, and dependency trust. Preserve safe rendering defaults.
