PlantUML with Next.js

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

PlantUML usage guidance

Best for

  • UML modeling
  • Class and sequence diagrams
  • Architecture documentation

Syntax tip

Use explicit participant aliases and avoid deeply nested groups for better readability.

Quick start

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

Recommended flow

  1. Store your PlantUML 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

Next.js implementation checklist

  • Create a server route for rendering
  • Cache responses for repeated diagrams
  • Render SVG safely in server components
