ApiSpark Technical Summary ApiSpark (also branded as MakeBoldSpark) is a modular ASP.NET Core backend API platform designed to consolidate multiple low-volume personal and portfolio APIs into a single, cost-effective Azure-hosted application. The platform serves as the centralized API layer for static websites and Single Page Applications, enabling a static-first architecture where public-facing sites remain lightweight while all business logic and data operations are delegated to this unified backend. Built on .NET (targeting .NET 10 LTS), Entity Framework Core, and SQLite for relational data with optional Azure Cosmos DB for document-oriented scenarios, the architecture implements role-based access control through distinct API route areas (/api/public/, /api/admin/, /api/publish/, /api/integrations/) that enforce authentication and authorization at the endpoint level. The project is optimized for Azure infrastructure—specifically Azure App Service (Linux B1 tier) with persistent SQLite storage and Azure Static Web Apps integration—making it particularly suited for developers and technical architects seeking to demonstrate scalable, maintainable multi-tenant API hosting patterns without enterprise-level complexity or cost. Its standout features include browser-based CMS/admin capabilities, static JSON generation for content websites, shallow and deep health check endpoints, and comprehensive Architecture Decision Records (ADRs) documenting design rationale. Though currently inactive (zero recent commits and no community engagement), ApiSpark functions as both a functional backend system for the MakeBoldSpark portfolio and an educational reference implementation for hosting multiple ASP.NET Core microservices cost-effectively on Azure.
