OpenApi-TS-Generator

NPM package based on swagger-ts-generator to generate typescript models for endpoints documented by swagger using the relatively new OpenAPI spec.

TypeScript usage with a hosted OpenApi Spec document.

import { generateTsModels } from 'openapi-ts-generator';

generateTsModels({
  openApiJsonUrl: '{Your Swagger Enpoint URL here}',
  outputPath: './{outputFolder}/',
});

TypeScript usage with an OpenApi Spec document stored on your local computer.

import { generateTsModels } from 'openapi-ts-generator';

generateTsModels({
  openApiJsonFileName: '{location and file name of your OpenApi document}',
  outputPath: './{outputFolder}/',
});

Javascript usage with a hosted OpenApi Spec document.

const generator = require('openapi-ts-generator');

generator.generateTsModels({
  openApiJsonUrl: '{Your Swagger Enpoint URL here}',
  outputPath: './{outputFolder}/',
  genAngularFormGroups: true /* Set this to true if only if you're in an Angular project*/
});

Javascript usage with an OpenApi Spec document stored on your local computer.

const generator = require('openapi-ts-generator');

generator.generateTsModels({
  openApiJsonFileName: '{location and file name of your OpenApi document}',
  outputPath: './{outputFolder}/',
});

Want to include Angular FormGroup Factories?

const generator = require('openapi-ts-generator');

generator.generateTsModels({
  openApiJsonFileName: '{location and file name of your OpenApi document}',
  outputPath: './{outputFolder}/',
  genAngularFormGroups: true
});

Working example with NRSRx based service

import { generateTsModels } from 'openapi-ts-generator';

generateTsModels({
  openApiJsonUrl: 'https://im-wa-cmpo-nrsr.azurewebsites.net/swagger/v1/swagger.json',
  outputPath: './models/',
  typeFilterCallBack: (val, i, arr) => !val.name.endsWith('ODataEnvelope'),
  valuePropertyTypeFilterCallBack: (val, i, arr) => !val.name.startsWith('created') && !val.name.startsWith('updated'),
});
