BlockDiag with Next.js

Integration guide for teams shipping diagram rendering in Next.js.

BlockDiag usage guidance

Best for

  • General diagram rendering
  • Programmatic documentation pipelines
  • Automated visual generation

Syntax tip

Keep BlockDiag source deterministic and reusable across environments.

Quick start

Use a server route in Next.js to proxy BlockDiag source to ChartQuery, then render SVG in your page.

Recommended flow

  1. Store your BlockDiag source in code or markdown.
  2. Send source to a server-side endpoint backed by ChartQuery.
  3. Render returned SVG/PNG in Next.js pages and docs.

Typical Next.js integration path: /app/api/diagram/route.ts
