To start the app:

1. Clone repo

2. Switch to dev branch

3. Run npm i to install the dependencies.

4. The app supports 2 modes of running application (development and production)

   • To start app in dev mode please run npm run start:dev
   • To start app in prod mode please run npm run start:prod.

5. After running the app you can use. for example, Postman to send the request to the server.

With this server you can:

• receive all users using GET request and api/users path
• receive user by id using GET request and api/users/{userId} path. You can get the user id from GET api/users request.
• add user to the server using POST request and api/users.
  You must specify username, age and hobbies properties and put them into the body of your request
  username (string, required)
  age (number, required)
  hobbies — (array of strings or empty array, required)
  for example
  { "username": "user", "age": 33, "hobbies": ["sport"] }
• update user data using PUT request and api\users path. You need to specify all the fields as for POST request.
• delete user using DELETE request and api\users\{userId} path. You can get the user id from GET api/users request.

The server should answer with 400 and 404 codes if userId is invalid or user is missing or the path is not valid
