Adidas Coding Challenge, March 2023

Approach

• I used node 18 LTS current version
• The development environment has been Arch Linux for all tests with node, docker and kubernetes and VS Code as editor.
• The endpoint tests and their documentation have been carried out with Postman (collection is attached in the root of the project).
• As you can expect, I have developed three independent services.
• Connections are protected user-facing and between microservices
• To simplify the application, the HTTPS protocol has not been used, although mTLS should ideally be used for connections.
• I have used nodemon and concurrently dependencies to run the application easily, as well as jsonserver as a persistent database.
• I have used nodemailer with ethereal to simulate sending emails. When you create or delete a subscription you will see a link to check the email.
• You have a CI/CD diagram is attached in the root of the project.
• Due to lack of time, I have not done unit tests.

Run application

• Locally with node.js

  • Yon need nodejs and npm to run the application.
  • Run npm run custom_install to install all the dependencies.
  • Run npm start to run all microservices.
  • You can run npm install and npm start on each microservice to run them independently.

• On Docker

  • You need Docker to run the application.
  • Inside the three microservices folders you have a docker_readme.md file with the instructions to build and run the image on Docker.

• On a Kubernetes cluster

  • You need kubectl, k8s or similar to run the application.
  • Run kubectl create -f .\kube.yaml on the root of the project to build and deploy the cluster with the three services.
