• Child category can have further child categories.
• Category can have multiple products and product can have a multiple categories.
• The Entities must get saved in MongoDb and be retrieved via POST and GET Methods respectively.

• You need to design a proper Mongodb data model and create APIs to

• Add a category

  Content-Type: application/json
  
  {
      "Name": "Category {{$randomInt 0 1000}}",

Use "REST Client" extension for VS Code to emulate request for development

"Request.rest" File has implemented requests for quick start

https://github.com/Huachao/vscode-restclient

• docker-compose
  • docker-compose.yml file at root has development mongo instance listening on 27017
  • If using docker-compose you might need to stop local mongodb instance or change port

• Clone this repo

• Install dependencies by

  npm install

• Run service in development mode using nodemon watching for file changes

  npm run dev
