CLI Application API for codegeneration from OAS3

> This is an experimental library. Now supporting TypeScript data types and model. Also, generating experimental Angular2+ services.
>
> Supporting of other languages and frameworks might be possible in the future.

It's a part of @codegena scope.

See in action: https://codegena-playground.stackblitz.io/ / https://stackblitz.com/edit/codegena-playground.

Using in NodeJS scripts

Install (without optional dependencies):

``
npm i @codegena/oapi3ts-cli --no-optional
`

or

`
yarn add @codegena/oapi3ts-cli --ignore-optional
`

So you can use @codegena/oapi3ts-cli in NodeJS scripts. For example, lets create update-typings.js script with code:

`javascript
"use strict";

var cliLib = require('@codegena/oapi3ts-cli');
var cliApp = new cliLib.CliApplication;

cliApp.createTypings();
cliApp.createServices('angular');
`

Then launch:

`
node ./update-typings.js --srcPath ./specs/todo-app-spec.json --destPath ./ --separatedFiles true
`

Class CliApplication will get command line arguments destPath, srcPath and separatedFiles by itself.

#### CLI arguments

|--------------------|-------------------------------------------------------------------------------|
| srcPath | Path of url of JSON file with OpenAPI3 specification |
| destPath | Path for destination directory |
| separatedFiles | Whether should converted types been saved in separate files, or in single file |

Also, you can set some of options for convertor's configuration
config via CLI:
