@loopback/openapi-spec-builder

Make it easy to create OpenAPI specification documents in your tests using the builder pattern.

Overview

Creating a full OpenAPI spec document in automated tests is rather cumbersome, long JSON-like objects pollute the test test code and make it difficult for readers to distinguish between what's important in the test and what's just shared OpenAPI boilerplate.

OpenApiSpecBuilder utilizes Test Data Builder pattern to provide a TypeScript/JavaScript API allowing users to create full OpenAPI Spec documents in few lines of code.

Installation

npm install --save-dev @loopback/openapi-spec-builder

This package is typically used in tests, save it to devDependencies via --save-dev.

Basic use

import {
  anOpenApiSpec,
  OpenApiSpecBuilder,
} from '@loopback/openapi-spec-builder';
 
const spec = anOpenApiSpec()
  .withOperationReturningString('get', '/hello', 'greet')
  .build();
 
// which is equivalent to the following longer form
const spec = new OpenApiSpecBuilder()
  .withOperation('get', '/hello', {
    'x-operation-name': 'greet',
    responses: {
      '200': {
        description: 'The string result.',
        content: {
          'text/plain': {
            schema: {
              type: 'string',
            },
          },
        },
      },
    },
  })
  .build();
 
// the spec
const spec = {
  openapi: '3.0.0',
  info: {title: 'LoopBack Application', version: '1.0.0'},
  servers: [
    {
      url: '/',
    },
  ],
  paths: {
    '/hello': {
      get: {
        'x-operation-name': 'greet',
        responses: {
          '200': {
            description: 'The string result.',
            content: {
              'text/plain': {
                schema: {
                  type: 'string',
                },
              },
            },
          },
        },
      },
    },
  },
};
