Package Exports

@loopback/openapi-v2

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 (@loopback/openapi-v2) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@loopback/openapi-v2

This package contains:

Decorators that describe LoopBack artifacts as OpenAPI v2 (Swagger) metadata.
Utilities that transfer LoopBack metadata to OpenAPI v2 (Swagger) swagger specifications.

Overview

The package has functions described above for LoopBack controller classes. Decorators apply REST api mapping metadata to controller classes and their members. And utilities that inspect controller classes to build OpenAPI v2 (Swagger) specifications from REST api mapping metadata.

Functions for more artifacts will be added when we need.

Installation

$ npm install --save @loopback/openapi-v2

Basic use

Currently this package only has spec generator for controllers. It generates swagger paths and basePath specs for a given decorated controller class.

Here is an example of calling function getControllerSpec to generate the swagger spec:

import {api, getControllerSpec} from '@loopback/openapi-v2';

@api(somePathSpec)
class MyController {
    greet() {
        return 'Hello world!';
    }
}

const myControllerSpec = getControllerSpec(MyController);

then the myControllerSpec will be:

{
    swagger: '2.0',
    basePath: '/',
    info: { title: 'LoopBack Application', version: '1.0.0' },
    paths: { 
        '/greet': { 
            get: {
                responses:  { 
                    '200': { 
                        description: 'The string result.', 
                        schema: { type: 'string' } 
                    } 
                },
                'x-operation-name': 'greet' 
            }
        } 
    } 
}
