Task Tracker Application

This is a task tracking application built with a FastAPI backend, PostgreSQL database, and a React frontend with TypeScript. The application allows users to track their tasks, record start and end times, and calculate the duration of each task. Additionally, users can see their tasks using a GraphQL API.

Features

• Task Tracking: Start and stop tasks with a description via Desktop GUI.
• Time Duration Calculation: Automatically calculate the duration of tasks.
• GraphQL API: Query tasks within a specified time period.
• React Frontend: View and query tasks through a user-friendly web interface.

Technologies Used

• Backend: Python 3.11.3, FastAPI, SQLAlchemy, PostgreSQL, Pydantic
• Frontend: React, TypeScript
• GraphQL: Graphene (Python library for GraphQL)
• DesktopGUI: Python 3.11.3, PyQT5

Installation

1. Clone the Repository:

   git clone https://github.com/egor-bondarev/Tracker.git
   cd Tracker

2. Run Backend services and Postgres in Docker:

   make run_tracker

3. Run the React Application:

   cd web_ui/tracker-client
   npm start

   Web UI will be available on http://localhost:3000

4. Run Desktop GUI:

   cd ../..
   cd ./desktop_gui
   python ./main.py

   

Usage

1. On desktop GUI type your task description and press Start.
2. After finishing your task press Stop.
3. If you forgot to start your task, you may type description and press Stop. In this case start time will be a finish time from your previous task.
4. To see your tasks list go to web ui (http://localhost:3000), set start and finish time by mask "YYYY-MM-DD hh:mm:ss" and click "Show Tasks".

Architecture

Record service:

This service works with desktop gui and write data to database.

API Endpoints:

• Start a new Task:

  POST /new/?is_task_finished=false
  

• Finish started Task:

  POST /finish/
  

• Start and Finish a new Task:

  POST /new/?is_task_finished=true
  

Analytic service:

This service works with web ui and show tasks list via GraphQL request.

API Endpoints:

• Get Tasks from period:

query GetTasksInPeriod($startDate: DateTime!, $endDate: DateTime!) {
    tasksInPeriod(start_date: $startDate, end_date: $endDate) {
        id
        description
        start_timestamp
        finish_timestamp
        duration
    }
}
