restViz

restViz is a lightweight library designed to create a dynamic web interface for Express applications. It automatically lists all defined API routes, providing an interactive interface to explore and document your API.

Features

• Automatic Route Discovery: Detects and lists all routes defined in your Express app.
• Dynamic API Documentation: No need for manually updating documentation as your app evolves.
• Seamless Integration: Works seamlessly with Express without additional configurations.

---

Installation

Install restViz using NPM:

npm install restviz

How It Works

• Simply import init from restviz and pass (express).
• pass init in your app.use(init(express)).
• Run your app, and restViz will generate a dynamic web interface listing all your routes.

Example Output: After starting your app, visit http://localhost:your-port-here in your browser. You’ll see:

A list of all defined routes:

GET /
PUT /
POST /
DELETE /
PATCH /

Configuration Options You can customize restViz by passing options to restViz.init():

import { init, Options, Theme } from 'restviz'

const app = express()

const theme: Theme = 'light'

const options: Options = {
  title: 'My API Documentation', // Set a custom title for the web interface
  theme: 'dark', // Choose between "light" or "dark" theme
}

app.use(init(express, options))

Available Options title: Customizes the web interface title (default: "API Documentation"). theme: Chooses the theme for the interface (default: "light")

Compatibility

⚠️ Note: restViz is currently compatible with Express v4. Support for Express v5 is not guaranteed and may result in unexpected behavior due to structural changes in routing and middleware handling. Please ensure your project uses Express v4:

npm install express@^4.18.0

Addtional usage

You can enrich your route documentation using metadata annotations. These are attached to each route and enhance the clarity and purpose of your API documentation.

Supported Metadata Fields:

• description: A brief explanation of what the endpoint does.
  Example: "description": "Update user details"

• notes: Extra details like warnings, use cases, or behavior explanation.
  Example: "notes": "Only admins can perform this action."

• responses: A key-value map describing expected HTTP response codes and their meanings.
  Example:

  "responses": {
    "200": "Success",
    "400": "Bad request",
    "401": "Unauthorized"
  }
