simplediag

A small TypeScript renderer for nwdiag-compatible network diagrams. Pure JS, browser-native, no Python/Java backend required.

import { renderFromSource } from "simplediag";

const { svg } = renderFromSource(`
nwdiag {
  network dmz {
    address = "10.0.0.0/24";
    web01 [address = ".10"];
    web02 [address = ".11"];
  }
}
`);
