Minitwit

An application created for the 'DevOps, Software Evolution and Software Maintenance' course at ITU in Copenhagen. This application was refactored from the original minitwit project written in Python using flask.

Since then, it's been refactored to use TypeScript using modern DevOps features and practices:

• Continuous integration using GitHub Actions, with automatic unit testing, static analysis and coverage reporting.
• Continuous delivery through GitHub releases.
• Containerized using Docker.
• Logging support using Pino, ElasticSearch and Kibana.
• Performance monitoring using Promethus which is integrated through Grafana.
