This is a simple Express.js application that uses the Kroki API to generate Mermaid diagrams in SVG format.

Features

• Generates an SVG diagram using Kroki's API.
• Returns the generated SVG diagram in the response.

Usage

1. Start the server

npm run dev

2. The server will start on http://localhost:3000 (or any other port specified in the .env file).

3. To generate a diagram, send a POST request to /generate with the following JSON payload:

}

Replace the diagram value with your Mermaid diagram source code.
