sails-hook-swagger

Important! develoment in progress..

• swagger.io hook for Sails JS.
• Customized to support the Swagger 2.0 specification, it is a simple and clean solution to integrate swagger with Sails JS, the application's models, controllers, and routes are automatically aggregated and transformed into a Swagger Document.
• Based in forks(outdated) of swagger-express, sails-swagger, sails-swagr and [sails-custom-swagger-hook][https://github.com/jasancheg/sails-custom-swagger-hook], but uptate and personalize to use with up to date dependencies and with a couple of extra features for allow inject CSS and JS files for brand personalization.

Summary

This module will do it best to autogenerate everything it can from Sails configuration and create a Swagger 2.0 JSON Specification to be used with the Swagger-UI. After routes and models have been generated, you may create a docs directory under api/ and place YML documents with paths definitions for each Controller. As a result, the generated JSONs and YAMLs will be merged.

Here is how documentation API page looks like (sample):

Logs

Installation

$ npm install @afidoss/sails-hook-swagger --save

Quick Start

Configure hook as express middleware.

Key	Example value	Description
apiVersion	'1.0'	Your api version. (optional)
swaggerVersion	'2.0'	Swagger version.(optional)
swaggerURL	'/api/docs'	Path to use for swagger ui web interface.(required)
swaggerJSON	'/api-docs.json'	Path to use for swagger ui JSON.(required)
basePath	process.env.HOST_NAME | | 'http://localhost:1337'	The basePath for swagger.js .(required)
info	{ title: '', description: ''}	[Metadata][info] about the API (optional)
apis	['./api/docs/User.yml']	Define your api array. (optional)
ui	'new'	Value list complet is: new, last or custom. Default is new
uiIndex	'index.html'	Index of ui .Default is index.html
docsFile	true	Is used for load documentation with file
swaggerDocsFile	'assets/api/docs-api.json'	manuelly set documentation of api on format json or yml.use this un production after set docsFile to true
uiPath	'/path-of-swagger-ui'	if ui= custom, you must specify this,otherwise that will throw error
folder	'/assets/docs'	Path to folder where custom-swagger.css and custom-swagger.js are stored (optional)

Note:

• Currently the implementation for personalization is very basic, you can place the folder for the customization files in any convenient folder of your application, for example assets/docs, however the name for the css/js files are mandatory. For properly operation of the hook please preserve the name for custom-swagger.css and custom-swagger.js
• Files placed in your customization folder are availables as static assets, For example if your customization folder is assets/docs any file placed on the folder is available in the url {host path}/api/docs/{file path/name}

Simple set sails.config.appPath variable

Read:

• Environment-specific files
• sails get base url

Steps (e.g.):

• In your config/local.js file add the value swagger.basePath': "http://localhost:1337"
• In your config/env/heroku.js file add the value swagger.basePath: "http://myapp.herokuapp.com"
• In your config/env/development.js file add the value swagger.basePath: "http://dev.myapp.com"
• In your config/env/staging.js file add the value swagger.basePath: "http://stg.myapp.com"
• In your config/env/production.js file add the value swagger.basePath: "http://myapp.com"
• Set the properly NODE_ENV variable on each environment that you configure

Sails Integration

Create the config/swagger.js to look like:

module.exports.swagger = {
    apiVersion: '1.0',
    swaggerVersion: '2.0',
    swaggerURL: '/api/docs',
    swaggerJSON: '/api-docs.json',
    basePath: process.env.HOST_NAME||'http://localhost:1337',
    info: {
      title: ' App API Documentation',
      description: ' API Swagger'
    },

    apis: [
        "Users.yml"
    ]
  }

Generate api documentation in command-line

Add this code on .sailsrc file:

{
  "modules": {
    "swagger": "@afidoss/sails-hook-swagger/generate"
  }
}

Next stape execute this command-line:

$ sails generate swagger

we will see :

you can also specify filename like: sails generate swagger my-api.yml

Note:

• commande line can support yml and json output
• you can also specify filename like: sails generate swagger my-api.yml

Inject files for look and feel customization, a JS and CSS file

Place the personalization files in your selected folder, for example '/assets/docs'. Find below a example for each one of this files:

// @Name: custom-swagger.js

// Swagger UI uses jQuery,
// so there is not problem with to use it here
$(document).ready(function() {

  // Change page title
  $("title").text("App Name");

  // Change logo link
  $("#logo").attr(
    'href',
    document.location.protocol + '//' + document.location.host
  );

  // Change brand text
  $(".logo__title").text("App name");

  // Change logo image
  // all files added to the folder with custom files
  // is public in /api/docs/{path to file}
  // also you can use the assets folder provided by sails
  // to store an image or point to an external file
  $(".logo__img").attr({
    alt: "App name",
    height: "30",
    width: "30",
    src: "my-logo.png"
  });

});

CSS file

/* @Name: custom-swagger.css */

#custom-swagger .swagger-section #header {
  background-color: #2BA0D3;
}

#custom-swagger .swagger-section #explore,
#custom-swagger .swagger-section #auth_container .authorize__btn {
  background-color: #42BFeF;
}

#custom-swagger .swagger-section #api_selector input {
  height: 20px;
  padding: 4px 12px;
  background-color: #fff;
  background-image: none;
  border: 1px solid #ccc;
  border-radius: 4px;
  box-shadow: inset 0 1px 1px rgba(0,0,0,.075);
  -webkit-transition: border-color ease-in-out .15s,box-shadow ease-in-out .15s;
  transition: border-color ease-in-out .15s,box-shadow ease-in-out .15s;
  color: #777;
  line-height: 1.4em;
}

Swagger-UI

Lift sails and navigate to the specified swaggerURL e.g.

http://localhost:1337/api/docs

Read from YAML file

Example 'Users.yml'

paths:
  /login:
    post:
      summary: Login with username and password
      notes: Returns a user based on username
      responseClass: User
      nickname: login
      consumes:
        - text/html
      parameters:

      - name: username
        dataType: string
        paramType: query
        required: true
        description: Your username

      - name: password
        dataType: string
        paramType: query
        required: true
        description: Your password

definitions:
  User:
    properties:
      username:
        type: String
      password:
        type: String
