Contact Manager SPA

ASP.NET Web API & Single Page Application C#| .NET 10| MySQL| HTML| CSS| JavaScript| Git

A modern Single Page Application (SPA) built on a REST API architecture for seamless contact management, featuring dictionary-based categorization, secure ASP.NET Identity authentication, and a streamlined layout.

Project Overview & Architecture

Developed as a quick Proof of Concept (PoC) / MVP to present a working concept to a client. The backend leverages .NET 10.0 Web API integrated with MySQL via Entity Framework Core. The interface acts as a streamlined SPA where login credentials, action forms, and data tables operate synchronously within a single persistent view, supported by clear user feedback and inline notifications.

Key Features & Endpoints

Contacts Controller: Handles comprehensive listing (`GetContact`), selective fetch, secure creation (`PostContact` with BCrypt hashing, requires authorization), and removal (`DeleteContact`).
Auth Controller: Manages user lifecycle including registration via ASP.NET Identity, session initialization (`Login`), and secure termination (`Logout`).
Structured Data Models: Relational schema utilizing `Contact` entities coupled with dictionary tables (`Category` / `SubCategory`) for systematic segmentation.
Default Credentials: Preconfigured admin setup for quick testing-Email: admin@admin.com | Password: Admin123!.
