Key Speakers:

• Alper Ebicoglu: ABP Core Team, provided updates on the ABP Framework and community contributions.
• Halil İbrahim Kalkan: ABP Core Team, presented on modular system design and implementation with ABP Framework.
• Ariful Islam: Co-founder and COO of Wafi Solutions, shared insights on using ABP in real-world projects.

I. ABP Community News (Alper Ebicoglu)

• Highlighted recent articles on the ABP Community platform covering topics like:
• Multilanguage functionality in ABP Framework.
• Cookies vs. local storage in web applications.
• .NET 9 features and ABP Framework compatibility.
• Integration of ABP with Inertia.js, React, and Vite.
• SignalR enhancements in .NET 9.
• Announced the release of ABP Framework version 8.3 with numerous bug fixes and improvements.
• Recognized top contributors to the ABP Community platform.

II. Modular Monolith Application Development (Halil İbrahim Kalkan)

A. Why Modularity?

• Reducing and managing code complexity: Enables parallel development, simplifies code maintenance, and allows for easier onboarding of new developers.
• Modular deployment: Allows customized deployments based on client needs, including or excluding specific modules.
• Microservice migration: Provides a foundation for future migration to a microservice architecture.

B. Module Types:

• Business Modules: Core functionalities directly related to the application’s business logic.
• Aggregator Modules: Combine data from multiple modules, typically for reporting or dashboards.
• Infrastructure Modules: Provide shared functionalities like settings management, permission management, background jobs, etc.
• Generic Modules: Offer cross-cutting concerns like audit logging, GDPR compliance, etc.

C. Architectural Considerations:

• Database: Single database: Easier for reporting and transactions, with potential scaling limitations.
• Separate databases: Improved data isolation, scalability, and more complex reporting and transactions.
• Codebase: Single solution: Easier for small teams and rapid development, potential for tighter coupling.
• Separate solutions: Encourages module isolation and increased complexity for multi-module development.
• Monorepo vs. multirepo: Monorepo simplifies versioning and deployment, while multirepo allows for more independent development.
• User Interface:
  • Unified UI: Simpler to develop pages utilizing multiple modules, less modular UI.
  • Modular UI: Promotes UI module isolation and challenges in integrating UI across modules.
  • Component-based UI: Balances modularity with cross-module integration.

D. Module Integration:

• Dependencies: Modules should depend on each other’s contracts (interfaces, DTOs, events), not implementations.
• Communication patterns: Direct API calls are suitable for read operations and prioritize caching.
• Integration events: Best for side effects triggered by changes in one module affecting another.

E. ABP Framework Tutorial:

• Demonstrated a step-by-step tutorial available on the ABP Framework website, covering:
• Creating a new solution with ABP Studio.
• Building modules with DDD principles.
• Implementing module integration using services and events.
• Performing database operations across modules.

III. Real-World ABP Experiences (Ariful Islam)

• Shared experiences from using ABP Framework for various projects, including large-scale SaaS applications.
• Highlighted the benefits of ABP in addressing challenges like:
• Multi-tenancy implementation.
• Supporting both cloud and on-premise deployments.
• Implementing recurring payments with Stripe.
• Building modular applications tailored to diverse customer needs.
• Emphasized the value of ABP’s:
• Pre-built modules and features (multi-tenancy, roles, settings, identity).
• DDD implementation and architectural guidance.
• Documentation and open-source projects as learning resources.
• Customization capabilities through extension methods and data filters.

IV. Q&A Session

• Addressed various community questions, including:
• Creating projects with multiple modules and Angular UI.
• Availability of simplified module templates.
• Choosing between modular monolith and single-layered architecture.
• Security controls are available in ABP Framework.
• Plans to move away from jQuery in ABP’s UI.

V. Key Takeaways:

• ABP Framework provides a robust foundation for building modular monolith applications with .NET.
• Modularity offers significant advantages for managing complexity, enabling flexible deployment, and easing potential microservice migration.
• The ABP Framework community is active and offers valuable resources for learning and sharing experiences.
• The ABP team continuously evolves the framework, adds new features, and addresses community needs.

Quotes:

“I honestly did not find any alternative to ABP for SaaS applications. It is very easy to get started.” — Ariful Islam.

“ABP provides us with nice architecture and nice documentation. We learn a lot from ABP documentation and the projects.” — Ariful Islam.

“ABP Studio is not a replacement for ABP Suite. You can use ABP Suite to create CRUD pages, and it’s inside ABP Studio.” — Alper Ebicoglu.
