Usage config in file

This package use cosmiconfig for find config.

Config can exist next places

• a swagger-to-js property in package.json
• a .swagger-to-jsrc file in JSON or YAML format
• a .swagger-to-jsrc.json file
• a .swagger-to-jsrc.yaml, .swagger-to-jsrc.yml, or .swagger-to-jsrc.js file
• a swagger-to-js.config.js file exporting a JS object

module.exports = {
  // Path to file with api (*.json, *.yaml, url)
  file: "./swagger-api.json", // string

  // Api in json (if not use option 'file', more important than path to file)
  apiJson: { ... },

  // Auth token for get api by url (it is header for request)
  authorization: "Token 123qwerty", // string

  // Path output directory js api with types
  outputDir: "./api", // string (default: "./api")

  // Mode for additional info
  mode: "prod", // "prod" | "dev" (default: "prod")

  // Action for deprecated methods
  deprecated: "warning", // "warning" | "ignore" | "exception" (default: "warning")

  // Import request code in out code
  // true — add import from `swagger-to-js/request`
  // false — embed request to `outputDir` and import from it
  // "disabled" — completely disable imporing `request`, use `templateCodeBefore`
  importRequest: true, // (default: false)

  // Build with original request body
  originalBody: true, // (default: false)

  // Ignore description of requests
  ignoreDescription: true, // default: false

  // Completely disable generating types file (.d.ts)
  disableTypesGenerate: true, // (default: false)

API

import { swaggerToJs } from "swagger-to-js";

const { code, types } = swaggerToJs({
  file: "./swagger-api.json",
});

console.log(code);
// => js code

console.log(types);
// => typescript types

Additional notes

• If you will use this package after application created, you will have problem with generated api, because current api in your app will have different with your swagger api maybe.

How to create custom preset

1. Create new NPM package (create directory and npm init there)
2. Name your package with -swagger-to-js-preset suffix
3. Create index.js and set "main": "index.js" in your package.json
4. Fill your index.js with any properties from list before
5. Save and publish
6. Use it like: presets: ['example-swagger-to-js-preset']

Hint: if you want to use local file as a preset, just use require.resolve: presets: [require.resolve('./local-preset')] It is works only in .js configs

Tests swagger versions

• 2.0
• 3.0.1
• 3.0.2

Roadmap

• Struct generated files by tags
