@flink-app/api-docs-plugin v0.12.1-alpha.19

Flink API Docs Plugin

A FLINK plugin that automatically generates beautiful API documentation based on your app's registered routes and schemas. This plugin provides a modern, Swagger-like interface for exploring and understanding your API endpoints.

Features

• 🚀 Automatic API documentation generation
• 🔍 Detailed request/response schema documentation

Installation

Install the plugin to your Flink app project:

npm i -S @flink-app/api-docs-plugin

Usage

Add and configure the plugin in your app startup (typically in your root index.ts):

import { apiDocPlugin } from "@flink-app/api-docs-plugin";

function start() {
    new FlinkApp<AppContext>({
        name: "My app",
        plugins: [
            // Register plugin with custom options
            apiDocPlugin({
                title: "API Docs: My app",
                path: "/docs", // Optional: defaults to "/docs"
                apiPath: "/docs/api", // Optional: defaults to "/docs/api"
            }),
        ],
    }).start();
}

Configuration Options

The plugin accepts the following configuration options:

How It Works

The plugin automatically:

1. Sets up a static file server at the specified path (defaults to /docs)
2. Creates an API endpoint at /docs/api that exposes route information
3. Serves a React application that fetches and displays your API documentation
4. Groups endpoints by resource for better organization
5. Displays detailed request/response schemas with proper TypeScript types

Development

For local development of the API documentation UI:

1. Start the mock API server:

   npm run dev:mock-api

2. In another terminal, start the React development server:

   npm run dev:react

3. Open http://localhost:5173 in your browser

The development setup includes hot-reloading for the React application, allowing you to see changes instantly as you modify the UI components.

Architecture

The plugin consists of two main parts:

1. Express Plugin: Integrates with your Flink application to serve the documentation
2. React Application: Modern UI that displays the API documentation

The React app uses:

• Tailwind CSS for styling
• TypeScript for type safety
• Vite for fast development and building

Requirements

• Node.js v20.17.0 or higher (as specified in root .nvmrc)
• A Flink application with Express initialized

UI Features

• Method Badges: Color-coded HTTP method indicators (GET, POST, PUT, DELETE, etc.)
• Expandable Sections: Click on endpoints to view detailed information
• Schema Tables: Well-formatted tables showing request/response properties
• Type Information: Clear display of property types and requirements
• Description Support: Built-in support for endpoint and property descriptions
• Mock Endpoint Indicators: Visual indicators for mocked endpoints
• Responsive Design: Works seamlessly on desktop and mobile devices
• TypeScript Interface Generation: Copy TypeScript interfaces for request/response bodies

Building

To build the complete plugin:

npm run prepare

This will:

1. Build the React application
2. Compile TypeScript files
3. Copy all necessary assets to the dist directory

The built plugin can then be published to npm and used in any Flink application.
