Webinar: PWA Deep Dive: Offlineanwendungen im Griff
Christian hat in seinem Webinar am 18. September 2020 über Progressive Web Apps die Offline-Fähigkeit in den Mittelpunkt gerückt - denn: zentrale Eigenschaft jeder Progressive Web App (PWA) ist die Verbindungsunabhängigkeit. Dank dem Service Worker funktioniert die App auch dann, wenn der Anwender gerade offline ist: im Tunnel, im Park oder im Dschungel. Bei der Generierung eines Service Workers hilft das Toolkit Workbox.
Anwenderdaten werden hingegen in der Browserdatenbank IndexedDB hinterlegt. Wo Daten offline gehalten werden, müssen aber auch deren Synchronisierung und Konfliktauflösung in der Architektur bedacht werden. Christian Liebel zeigt Ihnen die Mechanik hinter dem Service-Worker-Cache und der Browserdatenbank IndexedDB, sodass es auch Ihre PWA mit den nativen Gegenstücken problemlos aufnehmen kann.
Christian Liebel ist Consultant bei Thinktecture. Sein Fokus liegt auf Webstandards und Progressive Web Apps. Er vertritt Thinktecture beim W3C.

Advanced Value Object Patterns in .NET
While basic value objects solve primitive obsession, complex domain requirements need sophisticated modeling techniques. This article explores advanced patterns using Thinktecture.Runtime.Extensions to tackle real-world scenarios: open-ended dates for employment contracts, composite file identifiers across storage systems, recurring anniversaries without year components, and geographical jurisdictions using discriminated unions.

Discriminated Unions in .NET: Modeling States and Variants
Domain models often involve concepts that exist in multiple distinct states or variations. Traditional approaches using enums and nullable properties can lead to invalid states and scattered logic. This article explores how discriminated unions provide a structured, type-safe way to model domain variants in .NET, aligning perfectly with Domain-Driven Design principles while enforcing invariants at the type level.

Value Objects in .NET: Enhancing Business Semantics
Value objects are fundamental building blocks in Domain-Driven Design, serving far more than simple data wrappers. This article explores their strategic importance in bridging technical code and business concepts, enforcing domain rules, and fostering clearer communication with domain experts. Learn how to build robust aggregates, cultivate ubiquitous language, and encapsulate domain-specific behavior using Thinktecture.Runtime.Extensions in .NET applications.

Pattern Matching with Discriminated Unions in .NET
Traditional C# pattern matching with switch statements and if/else chains is error-prone and doesn't guarantee exhaustive handling of all cases. When you add new types or states, it's easy to miss updating conditional logic, leading to runtime bugs. The library Thinktecture.Runtime.Extensions solves this with built-in Switch and Map methods for discriminated unions that enforce compile-time exhaustiveness checking.

Value Objects in .NET: Integration with Frameworks and Libraries
Value Objects in .NET provide a structured way to improve consistency and maintainability in domain modeling. This article examines their integration with popular frameworks and libraries, highlighting best practices for seamless implementation. From working with Entity Framework to leveraging their advantages in ASP.NET, we explore how Value Objects can be effectively incorporated into various architectures. By understanding their role in framework integration, developers can optimize data handling and enhance code clarity without unnecessary complexity.
