swaggerize-docs v1.0.0

swaggerize-docs

A complimentary swagger api docs that works especially well in conjunction with swaggerize-express.

NOTE: pre 1.0 did it a completely different way. This now is just a wrapper around swagger-parser with some default options in place.

Installation

npm install swaggerize-docs --save

You should also read up on the Swagger spec.

Usage

In pre 1.0 versions, the directory structure was automatically loaded into your paths property for your api docs. In this version, it leverages the path dereferencing used by swagger-parser.

The following code snippets layout an app that looks like this:

project/
├─ app.js
├─ docs/
│  ├─ main.yaml
│  ├─ paths/
│  │  ├─ users.yaml
│  │  └─ users/
│  │     └─ {id}.yaml
│  └─ definitions/
│     └─ User.yaml
└─ routes/
   ├─ users.js
   └─ users/
      └─ {id}.js

// app.js
'use strict';

var path = require('path');
var express = require('express');
var swagger = require('swaggerize-express');
var swaggerDocs = require('swaggerize-docs');
var app = express();

var DOCS_PATH = path.join(__dirname, 'docs', 'main.yaml');

swaggerDocs(DOCS_PATH).then(function(api) {
  app.use(swagger({
    api: api,
    docspath: '/api-docs'
    handlers: './routes'
  }));
  app.listen(8000, function() {
    console.log('server started');
  });
});

API Configuration

swaggerDocs(docs, options)

• docs (String|Object) If a string is passed, it will read that as a filepath. If you pass on object, it will read that as your swagger docs object.

• options (Object) This is just the options object as documented here
