apis-engine

Render a custom lightweight diagram DSL as a live, draggable node-and-edge diagram directly inside VS Code — no external services (no Mermaid, no PlantUML). Parsing and layout (via dagre) happen entirely inside the extension.

Features

• Open a live preview of a diagram written in the DSL via the Diagram: Open Preview command.
• Nodes and edges are laid out automatically and can be dragged around in the preview panel.
• Works on plain text/Markdown files — just write the DSL and preview it.

See DSL_GUIDE.md for the full syntax reference and example prompts for generating diagrams with an AI assistant.

Usage

1. Open a file containing diagram source written in the DSL.
2. Run the Diagram: Open Preview command from the Command Palette (Cmd+Shift+P / Ctrl+Shift+P).
3. The rendered diagram opens in a side panel and updates as you edit the source file.

Requirements

No external dependencies or services are required.

Known Issues

None currently tracked.
