Trident

Open-source core of Trident — a text-based diagramming tool.

This repo contains the parser, serializer, and read-only renderer. No auth, no collaboration, no dependencies.

What's here

Quick start

<script type="module">
import { Trident2DParserV2 } from './parser.js';
import { renderToSVG, renderToPNG, mountViewer } from './renderer-oss.js';

const parser = new Trident2DParserV2();

const markup = `trident
container backend color:#4A90E2 label:"Backend"
node api[API Server] in backend at (150, 100)
node db[Database]   in backend at (350, 100)
api --> |Query| db`;

// SVG string
const svg = await renderToSVG(markup, parser);

// Interactive canvas with zoom + pan (no editing)
await mountViewer(document.getElementById('diagram'), markup, parser);

// PNG blob (2× retina)
const blob = await renderToPNG(markup, parser, { scale: 2 });
</script>
