🚀 Quick Start

Basic Setup

const fastify = require('fastify')({ logger: true });
const elements = require('elements-fastify');

// Register the elements-fastify plugin
fastify.register(elements, {
  apiDescriptionUrl: '/openapi.json',
  title: 'My API Documentation',  // Optional: custom page title
  path: '/docs'  // Optional: custom path (defaults to '/docs')
});

// Serve your OpenAPI specification
fastify.get('/openapi.json', (request, reply) => {
  reply.sendFile('path/to/your/openapi.json');
});

// Run the server!
fastify.listen({ port: 3000 }, (err, address) => {
  if (err) {
    fastify.log.error(err);
    process.exit(1);
  }
  console.log(`Documentation available at http://localhost:3000/docs`);
});

⚙️ Configuration Options

Option	Type	Default	Description
apiDescriptionUrl	string	Required	URL to your OpenAPI specification (JSON or YAML)
title	string	'API Documentation'	Custom title for the documentation page
path	string	'/docs'	Path to serve the documentation

💡 How It Works

1. The plugin serves both the static CSS and JavaScript files from the @stoplight/elements package and generates an HTML page that includes the Stoplight Elements web component
2. The web component fetches your OpenAPI specification and renders interactive documentation
3. Developers can browse endpoints, test APIs directly in-browser, and understand your API quickly

📄 Example OpenAPI Specification

Place your OpenAPI specification file in your project and serve it with Fastify:

fastify.get('/openapi.json', (request, reply) => {
  reply.sendFile('public/openapi.json');
});
