This period established the foundational structure for a crypto trading application, introducing a Spring Boot backend with MongoDB and Kafka integration alongside an Angular 18 frontend. The work focused on setting up core security, data persistence, and event streaming capabilities while enforcing architectural standards through comprehensive unit and architecture validation tests. Development environments were standardized with Eclipse configurations and Helm charts for local Kubernetes deployment.

5 changes.

This period focused on expanding unit test coverage for backend components, including the MyUser controller, MongoQuoteRepository, and JWT utilities, while configuring test environments for MongoDB and Kubernetes. Additionally, system architecture diagrams were added to document the Angular and Spring system structure.

A new Helm chart named 'kafkadev' has been added to the minikube/kafka directory to facilitate local development environments. This chart provisions Zookeeper and Kafka deployments, along with their respective services and Kubernetes Secrets for configuration. The Kafka container image is sourced from 'soldevelo/kafka' (latest), while Zookeeper uses 'bitnami/zookeeper' (latest). The setup exposes Kafka via a NodePort service on port 9092 and configures the broker to connect to Zookeeper on port 2181, allowing users to deploy a functional message queue stack locally with minimal configuration.

This change introduces new Helm chart templates for the minikube Angular and Spring Boot application. The \_helpers.tpl file provides utility functions for generating resource names and listing environment variables from secrets and config maps. The kubTemplate.yaml file defines the Kubernetes resources required to run the application, including a Secret for sensitive configuration, PersistentVolume and PersistentVolumeClaim for MongoDB data storage, a Deployment and Service for the MongoDB database, and a Deployment and NodePort Service for the web application. The web application deployment includes liveness and startup probes configured to check the Spring Boot Actuator health endpoints.

This change introduces the initial Helm chart structure for deploying the Angular and Spring application integrated with Kafka. It includes the chart metadata (Chart.yaml), default configuration values (values.yaml), and ignore patterns (.helmignore). The configuration defines container images for the web application, MongoDB, Kafka (using the Soldevelo image), and Zookeeper (using the Bitnami image), along with service names, environment variables, and secret references required for the Kubernetes deployment.

This change introduces the foundational configuration files and assets for the backend service. It adds environment-specific Spring Boot configurations (application.properties, application-kafka.properties, application-prod.properties) that define Kafka connectivity, MongoDB connection strings with compression, JWT security settings, and Actuator health/metrics endpoints. Additionally, it includes a .gitignore for static assets, a log4j.xml for logging configuration, and a currencyReport.jrxml file for generating cryptocurrency reports using JasperReports.

The backend application is introduced with a new Spring Boot entry point and a comprehensive set of configuration classes. Security is handled via a JWT token filter and a web security configuration that enforces stateless sessions and sets Content Security Policy headers. The system integrates with MongoDB for persistence and scheduling locks, and configures Kafka for event streaming. REST controllers are added to expose endpoints for Bitfinex, Bitstamp, and Coinbase orderbooks and quotes, alongside user authentication and statistics. Scheduled tasks are implemented to periodically fetch market data and calculate averages, utilizing virtual threads for asynchronous execution.

This change introduces the foundational build and operational infrastructure for the Angular and Spring Boot application. It adds a Dockerfile targeting JDK 25 with specific JVM memory tuning, a .travis.yml configuration for Java 11 CI, and a .gitignore for IDE and build artifacts. Additionally, it provides shell scripts to manage local development dependencies (MongoDB 8.2, Kafka via Soldevelo image, Prometheus, Grafana, and Structurizr) and a Maven wrapper for consistent builds, establishing the environment required to run the application and its associated monitoring stack.
