Slade360-Backend-Screening-Challange

About The Project

This project was designed to test the skills/knowledge/experience that a SIL Backend Developer should possess for the purposes of recruitment. It can also be used as a yardstick for training and improving SIL’s existing backend developers.

The technical interview was built around a coding assignment that is designed to screen for the following basic skills:

  • Experience in developing REST and GraphQL APIs in Python/Go/C#/Java
  • Experience with a configuration management tool e.g. Chef, Puppet, Ansible etc
  • Experience working with containers and container orchestration tools:smile:
  • Experience writing automated tests at all levels - unit, integration and acceptance testing
  • Experience with CI/CD (any CI/CD platform)

They were particularly interested in:

  • Testing + coverage + CI/CD
  • HTTP and APIs e.g. REST
  • OAuth2
  • Web security e.g. XSS
  • Logic / flow of thought
  • Setting up a database
  • Version control

Roadmap

  • Create a simple Go service
  • Design a simple customers and orders database (Keeping it simple)
  • Add REST API to input/upload customers and orders:
    • Customers should have details e.g. names and code.
    • Orders have simple details e.g. amount and time
  • Impliment authentication and authorization via JWT
  • When an order is added, send the customer an SMS alterting them (You can use the Africa's talking SMS gateway and sandbox)
  • Write unit test (with coverage checking) and set up CI + automated CD. You can deploy to any PAAS/FAAS/IAAS of your choice.
  • Write a README for the project and host it on your GitHub.

Setup

You need to have Golang installed at the very least Go 1.20.3.

The easiest way to get started with the rest api in your local environment is to clone it using git:

git clone https://github.com/AbdulrahmanDaud10/slade360-customer-order-service.git

Environment Variables

You need to configure environment variables for the rest api to work as expected.

Copy the content on .env_example to .env file cat .env_example > .env

The .env file should look like this:

# Database Configurations
DB_HOST = "127.0.0.1"
DB_PORT = "5432"
DB_USER = "postgres"
DB_NAME = "customer_order"
DB_PASSWORD = ""

# Port for Application to listen and Server
LISTEN_ADDRESS = "127.0.0.1"
LISTEN_PORT = "3000"

# Africa's Talking Bulk SMS Configurations
BASE_LIVE_ENDPOINT    = " "
BASE_SANDBOX_ENDPOINT = " "
API_KEY               = " "
USERNAME              = " "

# The URL of our Auth0 Tenant Domain.
# If you're using a Custom Domain, be sure to set this to that value instead.
AUTH0_DOMAIN = ' '

# Our Auth0 application's Client ID.
AUTH0_CLIENT_ID = ' '

# Our Auth0 application's Client Secret.
AUTH0_CLIENT_SECRET = ' '

# The Callback URL of our application.
AUTH0_CALLBACK_URL = ' '

You can change the values to your own preference.
