The repository will contain a simple todo app for a perspective employer. The stack includes django, react, postgres and docker. As with code written outside business context, the app will differ from my usual coding style which is "minimalism and no gold-plating, test heavily but only end-to-end tests with unit tests only when required, comment heavily". The context of this app is a show of my technical skills, therefore, I will follow assignment requirements, choose careful standard style and probably do an overkill to demonstrate my abilities.
Since this is developed in my free time, I will take this opportunity to learn something new and use React, which I have never used before. I will follow parts of react tutorial but also check against http://todomvc.com/ when confused taking care not to use too much of their code.
The deploy to cloud should be straightforward to those familiar with docker[compose]. I planned to add pre-orchestration with Ansible but time is running out on me.
Note two env variables:
- CORS_ORIGIN_WHITELIST - whom should backend welcome
- REACT_APP_BACKEND_HOST - where is backend located
For the domains front1.com, front2.com, backend.com, one should provide these values in docker-compose.yml:
...
services:
frontend:
build:
args:
REACT_APP_BACKEND_HOST: http://backend_CHANGE_THIS.com
...
backend:
environment:
CORS_ORIGIN_WHITELIST: http://front1.com,http://front2.com
Two frontends are rather strange, this here is to demonstrate the relationships and capabilities.
