# express-jsdoc-swagger

With this library, you can document your express endpoints using swagger [OpenAPI 3 Specification](https://swagger.io/specification/) without writing YAML or JSON. You can write jsdoc comments on each endpoint, and the library is going to create the swagger UI.

## Prerequisites
This library assumes you are using:
1. [NodeJS](https://nodejs.org)
2. [Express.js](http://www.expressjs.com)

## Installation
```
npm i express-jsdoc-swagger
```

## Usage
```javascript
const express = require('express');
const expressJSDocSwagger = require('express-jsdoc-swagger');

const options = {
  info: {
    version: '1.0.0',
    title: 'Albums store',
    license: {
      name: 'MIT',
    },
  },
  security: {
    BasicAuth: {
      type: 'http',
      scheme: 'basic',
    },
  },
  filesPattern: ['./**/*.js'], // Glob pattern to find your jsdoc files
  swaggerUIPath: '/your-url', // SwaggerUI will be render in this url. Default: '/api-docs'
  baseDir: __dirname,
};

const app = express();
const PORT = 3000;

expressJSDocSwagger(app)(options);

/**
 * GET /api/v1
 * @summary This is the summary or description of the endpoint
 * @return {object} 200 - success response
 */
app.get('/api/v1', (req, res) => res.json({
  success: true,
}));

app.listen(PORT, () => console.log(`Example app listening at http://localhost:${PORT}`));

```

## Examples
1. Basic configuration
```javascript
const options = {
  info: {
    version: '1.0.0',
    title: 'Albums store',
    license: {
      name: 'MIT',
    },
  },
  security: {
    BasicAuth: {
      type: 'http',
      scheme: 'basic',
    },
  },
  filesPattern: ['./**/*.js'], // Glob pattern to find your jsdoc files
  baseDir: __dirname,
};
```

2. Components definition
```javascript
/**
 * A song type
 * @typedef {object} Song
 * @property {string} title.required - The title
 * @property {string} artist - The artist
 * @property {number} year - The year - double
 */
```

3. Endpoint that returns a `Songs` model array
```javascript
/**
 * GET /api/v1/albums
 * @summary This is the summary or description of the endpoint
 * @tags album
 * @return {array<Song>} 200 - success response - application/json
 */
app.get('/api/v1/albums', (req, res) => (
  res.json([{
    title: 'abum 1',
  }])
));
```

4. Basic endpoint definition with tags, params and basic authentication
```javascript
/**
 * GET /api/v1/album
 * @summary This is the summary or description of the endpoint
 * @security BasicAuth
 * @tags album
 * @param {string} name.query.required - name param description
 * @return {object} 200 - success response - application/json
 * @return {object} 400 - Bad request response
 */
app.get('/api/v1/album', (req, res) => (
  res.json({
    title: 'abum 1',
  })
));
```
