JS Poland is a premier technology conference in CEE, focused on JavaScript ecosystem Warsaw & Online October 2022


Modern Angular Architectures is an online course with live Q&A calls and a community of experienced Angular developers. In this interactive course, you will learn from Manfred Steyer - Angular GDE and Trusted Collaborator in the Angular team - how large enterprise-scale Angular applications can be planned and developed. For this, we learn how Domain Driven Design (DDD) can help with planning a huge solution and how Nx Monorepos can be used for implementing our Strategic Domain Design.

The async pipe is boring! We will skip ChangeDetection OnPush & trackBy and jump straight to the guts of performance. Exciting exercises as well as deep knowledge is core of this training.
Angular has known performance bottlenecks. Especially in larger applications. 

If you already know REDUX or reactive state management patterns and want to learn more about the internal architectural implementation details, this is the workshop you need to book. Local component state, flattening operators, contextual state and its display component templates.

It’s time to take the next step. If you feel you are comfortable with RxJS and confident to solve common challenges in your applications, this workshop is a perfect fit! Push ;) your knowledge to the next level and learn to handle the tricky things.

Business applications must be scalable, extendable and maintainable in the long term! This creates several challenges for the underlying software architecture.

In this workshop you will get to know some architectural styles, patterns and tools to master these challenges. You will learn how monorepos improve your architecture, how Nx supports you, and how it can be used to monitor and enforce your architecture.


This workshop will bring your RxJS skills to the next level! We will focus on **framework-agnostic** techniques that you can use to improve the UX of your application and learn about the essential parts of reactive architecture. Error handling, and retry strategies, as well as combination and flattening scenarios and also topics related to state management are just some of the topics covered in this workshop.

Learn how to leverage object-oriented programming principles and design patterns for creating modular, maintainable applications – in the context of modern UI development. Learn how to think, describe, and communicate with other developers using a common language and terms. Learn how to complex frameworks and libraries work under the hood by identifying the patterns that were used.
– You will use just TypeScript. No frameworks or external libraries.
– All patterns will be explained using real-world, practical use-cases.
– Solve real-world problems through hands-on exercises

During this training you will build a cloud-enabled offline-first Progressive Web App (PWA) that can seamlessly transition from online to offline while providing a great user experience. 

Offline-first apps need to support: intermittent connectivity, transition seamlessly between online and offline states, provide reliable CRUD on-device data, data synchronisation and data conflict resolution to enable real-time collaboration. Amplify DataStore is an on device persistent repository for interacting with local data and able to automatically synchronize via GraphQL. Using Amplify DataStore will allow us to implement offline-first while using a simple programming model.
