Controller Data Structure

postman-collection-generator creates postman collections from express controllers. In order for the collection and items to be generated correctly, each controller has to be a class that implements a PostmanControllerInterface and have the appropriate data structure. See example below:

// exampleController.ts
import {PostmanControllerInterface} from "@deskree/postman-collection-generator";

export class ExampleController implements PostmanControllerInterface {

    public name = 'Example Name of Postman Folder';
    public description = 'Example Description of Postman Folder';
    public routes = [
        {
            name: 'GET Something by id',
            url: '/example/{{id}}',
            method: 'GET',
            description: 'Get something from somewhere by some id',
            params: ['some_param=123'],
            headers: [{ key: 'Content-Type', value: 'application/json' }]
        },
        {
            name: 'Create Product',
            url: '/product',
            method: 'POST',
            body: {
                product: {
                    title: "Product Name",
                    price: 12,
                    tags: [
                        "Product"
                    ]
                }
