Purpose and topology

This is a two-part task-management application: a Java/Spring backend exposes task-related server functionality, while a React frontend renders task, calendar, and work-session UI. The repository has independent build roots at backend/pom.xml and frontend/package.json.

Backend application entry and HTTP boundary

Spring Boot starts from backend/src/main/java/com/example/taskManager/TaskManagerApplication.java. HTTP-facing code is concentrated in:

• backend/src/main/java/com/example/taskManager/TaskController.java

• backend/src/main/java/com/example/taskManager/HelloController.java

• backend/src/main/java/com/example/taskManager/HelloController2.java

TaskController is the primary task API boundary; the Hello controllers appear to provide simple connectivity or diagnostic endpoints. Browser-origin behavior is likely configured at backend/src/main/java/com/example/taskManager/config/WebConfig.java.

Task domain and persistence

The core backend domain is represented by backend/src/main/java/com/example/taskManager/Task.java. Persistence is isolated behind backend/src/main/java/com/example/taskManager/TaskRepository.java, establishing the expected flow: HTTP request → controller → repository → task storage → HTTP response.

Database-related configuration belongs in backend/src/main/resources/application.properties. backend/src/main/java/com/example/taskManager/PgTest.java indicates PostgreSQL is a material intended or tested database integration, though the supplied tree alone does not establish deployment credentials or schema-management behavior.

Frontend entry and composition

The browser application mounts through:

• frontend/src/index.js

• frontend/src/App.js

• frontend/public/index.html

App.js is the application composition point. It should coordinate UI state and backend interaction rather than placing cross-screen orchestration in individual presentation components.

Task-management UI stages

The frontend’s architecture is organized around task lifecycle and planning views:

• Task creation: frontend/src/components/AddTask.js

• Task list and per-item rendering: frontend/src/components/TaskList.js, frontend/src/components/TaskItem.js

• Calendar-oriented planning: frontend/src/components/Calendar.js

• Focus/work tracking: frontend/src/components/WorkSession.js

The primary client flow is user input in these components → frontend state/API request → Spring task endpoint → persisted task data → refreshed list/calendar/session views. Styling for the task-list boundary is colocated in frontend/src/components/TaskList.css.

Runtime and operational boundaries

The backend uses Maven/Maven Wrapper (backend/mvnw, backend/pom.xml) and runs on the JVM with Spring Boot. The frontend uses the Node/npm ecosystem (frontend/package.json, frontend/package-lock.json) and produces a browser application.

The frontend/backend network boundary and database boundary are the major integration points. Cross-origin handling is architecturally relevant because UI and server live in separate project roots; backend/src/main/java/com/example/taskManager/config/WebConfig.java is the likely policy owner. The unusual backend/src/main/java/com/example/taskManager/config/src/Main.java is inside the compiled Java source tree and should be checked for an additional executable or accidental source placement before restructuring.
