Package Exports

express-jsdoc-swagger

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (express-jsdoc-swagger) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

npm

express-jsdoc-swagger

With this library, you can document your express endpoints using swagger OpenAPI 3 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:

Installation

npm i express-jsdoc-swagger

Usage

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

Examples
