**One App to Rule Them All: Multi-tenancy Patterns With NestJS**
Join us as Dustin, CTO at SIMPL Technologies GmbH, shares practical insights into implementing multitenancy in NestJS applications.
This technical session will cover three essential patterns - Silo, Bridge, and Pool - along with their real-world implementations and trade-offs.
You'll learn:
\- Different multitenancy approaches and when to use them
\- Implementation strategies in NestJS
\- Security patterns\, including Row Level Security
\- Practical considerations for scaling multi\-tenant applications
Perfect for backend developers and architects building SaaS applications with Node.js/NestJS.

**How to Manage Modules in NestJS**
NestJS boasts about solving the lack of architecture often seen with other Node.js frameworks.
Indeed, it provides tools similar to Angular, enabling the development of modular applications and offering a robust Dependency Injection system. However, at the end of the day, it’s just a tool. If used incorrectly, your architecture can devolve into the infamous Big Ball of Mud antipattern.

In this talk, Maciej will explain why applications built with NestJS often suffer from dependency chaos between modules. He will also outline key principles to follow when planning your modules to avoid these issues and create a clean, maintainable architecture.
