What is swagger-jsdoc?

swagger-jsdoc is a Node.js library that allows you to integrate Swagger/OpenAPI documentation into your Express.js or other Node.js applications. It generates the Swagger specification based on JSDoc comments in your code, making it easier to maintain and update API documentation.

What are swagger-jsdoc's main functionalities?

Generate Swagger Documentation

This feature allows you to generate Swagger documentation from JSDoc comments in your code. The `options` object specifies the OpenAPI version, API info, and the files containing the JSDoc comments.

const swaggerJsdoc = require('swagger-jsdoc');
const options = {
  definition: {
    openapi: '3.0.0',
    info: {
      title: 'Express API with Swagger',
      version: '1.0.0',
    },
  },
  apis: ['./routes/*.js'], // files containing annotations as above
};
const swaggerSpec = swaggerJsdoc(options);

Integrate with Express

This feature demonstrates how to integrate Swagger UI with an Express application. The Swagger documentation is served at the `/api-docs` endpoint.

const express = require('express');
const swaggerUi = require('swagger-ui-express');
const swaggerJsdoc = require('swagger-jsdoc');

const app = express();
const options = {
  definition: {
    openapi: '3.0.0',
    info: {
      title: 'Express API with Swagger',
      version: '1.0.0',
    },
  },
  apis: ['./routes/*.js'],
};
const swaggerSpec = swaggerJsdoc(options);

app.use('/api-docs', swaggerUi.serve, swaggerUi.setup(swaggerSpec));

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

JSDoc Annotations

This feature shows how to use JSDoc annotations to document an API endpoint. The annotations provide metadata about the endpoint, such as the HTTP method, summary, and response schema.

/**
 * @swagger
 * /users:
 *   get:
 *     summary: Retrieve a list of users
 *     responses:
 *       200:
 *         description: A list of users
 *         content:
 *           application/json:
 *             schema:
 *               type: array
 *               items:
 *                 type: object
 *                 properties:
 *                   id:
 *                     type: integer
 *                   name:
 *                     type: string
 */
app.get('/users', (req, res) => {
  res.json([{ id: 1, name: 'John Doe' }]);
});
