A barebones node express app with some basic CRUD operations using an object in place of a database. Includes unit tests using supertest https://www.npmjs.com/package/supertest

---

Architecture

---

This app uses a common pattern of having controllers and routes in separate folders.

Controllers are used to manipulate and query data.

Routes simply listen for requests on certain paths and provide methods which are called on those routes.

Middlewares are methods that are called before the request goes to a controller. In this app, we have a validateUserBody middleware which ensures all incoming requests have an id property - if they DO NOT, we simply reject the request - if they DO, we continue the request using next

How To Use

---

You'll see many comments throughout the codebase which highlight common patterns and libraries.

There are 4 routes you can reach from your localhost like so:

http://localhost:5000/user/add

http://localhost:5000/user/get

http://localhost:5000/user/update

http://localhost:5000/user/delete

Examples:

To create a new user http://localhost:5000/user/add

{
    "id": "123",
    "email": "brianjenney83@gmail.com",
    "name": "brian"
}

To get a user with an id of 123: http://localhost:5000/user/get?id=123

Next Steps

---

You can create a true database connection to persist your data and add new routes, controllers and middlewares.
