dsh-plugin-mermaid

A DeepSeek Harness (DSH) web client plugin that renders ```mermaid code blocks in chat messages, with a chart ↔ source toggle and live theme switching.

• Mermaid v11 loaded on demand from a CDN (no bundle bloat).
• Follows DSH dark/light theme automatically.
• 500 ms debounce so streaming tokens don't thrash the renderer.
• Native DSH code-block banner integration: buttons sit right next to the built-in Copy button; source view keeps Shiki highlight and copy.
• Zero build step — the browser entry is hand-written factory-form CJS exactly as DSH's client-modules service expects.

Install

From GitHub (recommended)

This package ships prebuilt lib/ files and declares dsh.bundle, so it can be installed directly into the DSH web profile:

dsh plugin --profile web add github:lj970926/dsh-plugin-mermaid

Then restart dsh web and hard-refresh the browser (Cmd+Shift+R).

To pin a revision for reproducibility, append a commit SHA or tag:

dsh plugin --profile web add github:lj970926/dsh-plugin-mermaid#

Because the published files are already in lib/, this package has no prepare build step and does not require pnpm allowBuilds authorization. If you fork the repository and add a build step, follow DSH's packaging docs and add the package key under allowBuilds in the profile's pnpm-workspace.yaml when prompted.

From a local checkout

If you are developing the plugin, install the checkout as a linked bundle:

dsh plugin --profile web add /absolute/path/to/dsh-plugin-mermaid

Legacy copy script

The repository also keeps for copying files directly into an existing web profile:
