📝 Walkthrough

Walkthrough

Added Streamdown plugin integration to the Response component (code, math, mermaid) and broadened Tailwind's content scan in app/globals.css to include Streamdown distribution files and scoped Streamdown packages via glob patterns.

Changes

Cohort / File(s)	Summary
Tailwind content scan app/globals.css	Replaced single-file Streamdown scan with glob patterns: streamdown/dist/*.js, and added scoped package paths: @streamdown/code/dist/*.js, @streamdown/math/dist/*.js, @streamdown/mermaid/dist/*.js.
Streamdown rendering components/ai-elements/response.tsx	Imported code, math, mermaid plugins, assembled defaultPlugins, and passed them to Streamdown via plugins={defaultPlugins} to enable plugin-based transformations during rendering.

Poem

A few plugins join the rendering song,
Tailwind widens its watch, scanning long,
Code, math, mermaid — now parsed with care,
Components harmonize; output's laid bare. ✨

Restore Streamdown plugins before shipping v2

Any chat response that contains fenced code, Mermaid, or LaTeX will regress after this bump. Streamdown 2.x moved those capabilities behind optional plugins (@streamdown/code, @streamdown/mermaid, @streamdown/math, etc.; see the upstream README usage for plugins={{ ... }}), but our renderer still mounts bare <Streamdown {...props} /> in components/ai-elements/response.tsx:11-29 and there are no @streamdown/* imports anywhere in the repo. The previous lockfile entry for streamdown@1.6.10 bundled shiki, remark-math, and rehype-katex, so upgrading only the package version here silently drops syntax highlighting/copy UI and math rendering for existing responses.

Useful? React with 👍 / 👎.

app/globals.css (1)

10-13: Correctly configured Tailwind v4 content scanning for Streamdown plugins.

The @source directives properly extend Tailwind's class detection to include the Streamdown plugin distribution files. This ensures any Tailwind classes used by these plugins are included in the final CSS bundle.

Regarding the Stylelint errors: these are false positives. The @source directive is valid Tailwind CSS v4 syntax, but Stylelint's scss/at-rule-no-unknown rule doesn't recognize it. Consider updating your Stylelint configuration to ignore Tailwind-specific at-rules:

💡 Stylelint configuration suggestion

{
  "rules": {
    "scss/at-rule-no-unknown": [
      true,
      {
        "ignoreAtRules": ["source", "plugin", "theme", "custom-variant", "utility", "tailwind", "apply", "layer"]
      }
    ]
  }
}

Or if using a .stylelintrc.js:

module.exports = {
  rules: {
    "scss/at-rule-no-unknown": [
      true,
      {
        ignoreAtRules: ["source", "plugin", "theme", "custom-variant", "utility", "tailwind", "apply", "layer"]
      }
    ]
  }
};
