Tomograph

Convert API Blueprint, Swagger and OpenAPI to minimal routes with JSON Schema. For ease of use and creation of new tools.

Will look like

[
  {
    "path": "/sessions",
    "method": "POST",
    "content-type": "application/json",
    "requests": [{
      "$schema": "http://json-schema.org/draft-04/schema#",

        }
      },
      "required": [
        "login",
        "password"
      ]
    }],
    "responses": [

            }
          }
        }

    ]
  }
]

Installation

Then add this line to your application's Gemfile:

gem 'tomograph'

After that execute:

$ bundle

Or install the gem by yourself:

$ gem install tomograph

Usage

In code

OpenAPI 2.0

Also Swagger

require 'tomograph'

tomogram = Tomograph::Tomogram.new(openapi2_json_path: '/path/to/doc.json')

OpenAPI 3.0

Also OpenAPI

require 'tomograph'

tomogram = Tomograph::Tomogram.new(openapi3_yaml_path: '/path/to/doc.yaml')

API Blueprint

First you need to install drafter. Works after conversion from API Blueprint to API Elements (in YAML file) with Drafter.

That is, I mean that you first need to do this

drafter doc.apib -o doc.yaml

and then

require 'tomograph'

tomogram = Tomograph::Tomogram.new(drafter_yaml_path: '/path/to/doc.yaml')

Tomograph

To use additional features of the pre-converted

require 'tomograph'

tomogram = Tomograph::Tomogram.new(tomogram_json_path: '/path/to/doc.json')

prefix

Default: ''

You can specify API prefix and path to the spec using one of the possible formats:

Tomograph::Tomogram.new(prefix: '/api/v2', drafter_yaml_path: '/path/to/doc.yaml')

Tomograph::Tomogram.new(prefix: '/api/v2', tomogram_json_path: '/path/to/doc.json')

to_json

Use to_json for converting to JSON, example from API Blueprint:

tomogram.to_json

Example input

FORMAT: 1A
HOST: http://test.local

# project

# Group project

### Sign In [POST]

+ Request (application/json)

    + Attributes
     + login (string, required)

# Data Structures

      }
    ]
  }
]

to_a

tomogram.to_a

find_request

request = tomogram.find_request(method: 'GET', path: '/status/1?qwe=rty')

find_request_with_content_type

request = tomogram.find_request_with_content_type(method: 'GET', path: '/status/1?qwe=rty', content_type: 'application/json')

find_responses

responses = request.find_responses(status: '200')

prefix_match?

This may be useful if you specify a prefix.

tomogram.prefix_match?('http://local/api/v2/users')

to_resources

Maps resources for API Blueprint with possible requests.

Example output:

{
  '/sessions' => ['POST /sessions']
}

Command line tool

CLI allows you to convert files from API Blueprint (API Elements), Swagger and OpenAPI to JSON Schema.

Run CLI with -h to get detailed help:

tomograph -h

To specify the handler version use the -d flag:

OpenAPI 2.0

tomograph -d openapi2 openapi2.json tomogram.json

OpenAPI 3.0

tomograph -d openapi3 openapi3.yaml doc.json

API Blueprint

tomograph -d 4 apielemetns.yaml doc.json

exclude-description

Exclude "description" keys from json-schemas.

tomograph -d 4 apielemetns.yaml doc.json --exclude-description

split

Split output into files by method. Output in dir path.

tomograph -d 4 --split apielemetns.yaml jsons/
