WeatherTrack Pro - Performance Optimization Project

Overview

This project contains the WeatherTrack Pro application in two versions:

• old-code: Original version with performance issues
• new-code: Optimized version with fixes and improvements

Project Context

WeatherTrack Pro is a weather analysis application that provides comprehensive historical data for various geographic locations. Following the expansion of the data repository, significant performance issues appeared, including:

• Slowdown in data retrieval
• Inefficient analysis tools
• Negative impact on user experience

Objectives

• Identify and resolve performance issues
• Optimize data retrieval and processing
• Improve overall user experience

Documentation

• API.md - Complete API endpoints documentation
• OPTIMIZATIONS.md - Detailed list of optimizations performed

Quick Start

Prerequisites

• Docker and Docker Compose
• Node.js 20.10.0
• npm
• PowerShell (Windows)

Launch both versions

.\launch.ps1

Launch only the old version

.\launch.ps1 old

Launch only the new version

.\launch.ps1 new

Other available commands

.\launch.ps1 stop      # Stop all services
.\launch.ps1 restart   # Restart all services
.\launch.ps1 logs      # Display logs
.\launch.ps1 clean     # Stop and remove volumes
.\launch.ps1 help      # Display help

Run benchmarks

.\benchmark.ps1

This script compares the performance of both versions with different amounts of data in the database.

Benchmark features:

• Interactive choice of data sizes to test
• Progress bar for data generation
• Confirmation between each test
• Test of all endpoints (GET data, avg, max, min)
• Generation of a professional HTML report
• Automatic opening of the report in the browser

Ports

• old-code API: http://localhost:3000
• new-code API: http://localhost:3001
• old-code DB: localhost:5432
• new-code DB: localhost:5433

Testing with HTTP files

HTTP test files are available in the /http folder to quickly test the API endpoints.

Stop services

.\launch.ps1 stop

To also remove data volumes:

.\launch.ps1 clean
