SuaVez - Queue Managment

SuaVez is a robust Queue Management System designed for fast-food chains, restaurants, and multi-company environments. It provides advanced queue control, priority management, and customization options to enhance operational efficiency and customer satisfaction.

This project was initially developed as a monolithic ASP.NET Core 3.1 application with Identity Pages integrated as Razor, and later refactored into a layered architecture with Identity moved to an MVC structure.

[!CAUTION] This project was originally developed from an abandoned client project. It will be over-engineered with a lot of unnecessary complexity and features, and is not recommended for use in a production or product environment. While it has been adapted for inclusion in a portfolio, it may not follow best practices for scalability, performance, or maintainability. If you're considering using it, please review the code thoroughly and make the necessary adjustments before deploying to production.

Key Features

Core Queue Management

• Multiple Companies Support: Manage queues for multiple companies simultaneously. Each company can have its own queue, and users can choose which queue to join.
• Position Tracking and Exit Option: Users can see their current position in the queue and leave the queue directly from the interface.
• Priority Logic: Customizable priority rules to prioritize certain users (e.g., VIPs, urgent requests) based on roles or other criteria.
• Handling Multiple Queues: Supports managing multiple queues in parallel for efficient handling of large groups or multiple service points.

Customization and Flexibility

• Customizable UI: Users and admins can personalize the interface (e.g., color schemes, layouts) to match branding or preferences.
• Scalability: Designed to handle small restaurants to large fast-food chains with multiple locations.

Advanced Features

• Real-Time Notifications: Notify users of their queue status via SMS, mobile app, or on-site displays.
• Wait Time Estimation: Provide accurate wait time predictions based on queue length and service speed.
• Scheduler Integration (Planned): Future integration with a scheduler for time-based queue management (e.g., appointments, reserved times).

Technical Improvements

• Refactored Architecture: Migrated from a monolithic ASP.NET Core 3.1 application to a layered architecture:
  • LCFila.Web: Frontend UI written in Razor MVC.
  • LCFila.Application: Backend services.
  • LCFila.Infra: Infrastructure logic for database and external services.
  • LCFila.Domain: Core domain logic (e.g., queue management, priority logic).
• Identity Migration: Refactored Identity Pages from Razor to an MVC structure for better maintainability and scalability.
• Database Migrations: Implemented EF Core migrations for database management.

Key Components

• LCFila.Web - Frontend UI for user interaction.
• LCFila.Application - Backend services for business logic.
• LCFila.Infra - Infrastructure layer for database and external integrations.
• LCFila.Domain - Core domain logic, including queue management and priority rules.

Getting Started

Requirements

• .NET 8
• A modern web browser (for the frontend)
• Optional: Scheduler integration (planned feature)

Setup

1. Clone the repository: bash git clone https://github.com/luigicfilho/SuaVez.git
2. Navigate to the project folder:

bash cd SuaVez

1. Run the migrations to create database

bash dotnet tool install --global dotnet-ef dotnet ef migrations add Initial --startup-project .\LCFila.Web\LCFila.Web.csproj --project .\LCFila.Infra\LCFila.Infra.csproj dotnet ef database update --project .\LCFila.Infra\LCFila.Infra.csproj -s .\LCFila.Web\LCFila.Web.csproj dotnet ef migrations script -o ../fileName.sql --startup-project .\LCFila.Web\LCFila.Web.csproj --project .\LCFila.Infra\LCFila.Infra.csproj

1. Run the development server:

bash dotnet run

Usage

• For Customers:
  • Join a queue for a company.
  • Track your position in real time.
  • See estimated wait time.
  • Leave the queue at any time if desired.
• For Admins/Companies:
  • Set up and manage multiple queues.
  • Customize the UI for your company.
  • Manage customer positions and set priority rules.
  • Monitor active queues and their statuses.

Planned Features

• Scheduler Integration: Automatically assign slots to users based on availability and timing.

• Mobile Optimization: Make the platform mobile-responsive for better usability across devices.

• Notifications: Implement push notifications to alert users when their turn is approaching or if there is an issue with the queue.

Architecture Decision Records (ADRs)

This project follows a documented decision-making process for key architectural choices. Below are the Architecture Decision Records (ADRs) that explain the reasoning behind major technical decisions:

• ADR-1: Using MVC Web App

  • Decision to use Razor MVC for the frontend UI to leverage its simplicity and integration with ASP.NET Core.

• ADR-2: Adopt Layered Architecture

  • Decision to refactor the monolithic application into a layered architecture (Domain-Driven Design) for better maintainability and scalability.
