Serverless React with GraphQL and AWS Amplify - Master Class
by Marcin Mieszek

*AWS Amplify* makes it very easy to build cloud-enabled React applications. Using it you can easily create and configure in your app services like user signup and authentication, *GraphQL APIs* and *Lambda* functions. Amplify provides also a complete JavaScript SDK to connect your front-end application to these services. With *GraphQL* you can dictate exactly what data you need from the server and eliminate overfetching. In this workshop you will learn to utilise Amplify capabilities to quickly build a production-ready React application.

Hook up your React - Master Class
by Tomasz Ducin

Hooks is the new approach to tackle complex and cross cutting concerns in React applications. Not only it is the most important way forward for React, but also it becomes a standard architecture, being reimplemented in other major frameworks, becoming a de facto frontend standard. It is, however, completely different way to code than what you might be familiar with - and that’s why you should attend the workshop on hooks!

TypeScript - Master Class
by Miłosz Piechocki

During this workshop you will dive deep into TypeScript’s advanced features. First, we’ll see how to make type checks stricter so that TypeScript can catch more errors for you. Importantly, you’ll also learn how enable stricter checks on large existing codebases. Second, we’ll go through TypeScript’s many advanced types and see how they can be useful. Next, we’ll investigate TypeScript’s support for functional programming, which is becoming the dominant paradigm in frontend development. Finally, we’ll look at some of the features that are included in TypeScript’s roadmap so that when they finally come, you’ll be ready for them!

How to use NgRx in your Angular application - Master Class
by Alex Okrushko

NgRx is the de facto state management library for Angular apps at Google. It's widely used, well supported and is the great addition for any non-trivial web app. Whether you hadn't used NgRx before or were using it for a while - you'll learn something new during this training. We'll start the workshop with the step-by-step migration of the existing angular app to NgRx-based one - this will help you understand why, where and how to use it.

Scalable Node.js with NestJS - Master Class
by Kamil Myśliwiec

When Node.js came up for the first time, it was considered as an outstanding revolution. After few years, the platform evolved substantially, albeit, tooling wasn't good enough to compete with mature technologies from other languages. NestJS has been formed to bring hope back by applying modern techniques and design patterns to the Node.js world. Finally, we've got a framework that allows creating progressive server-side applications, we back to the game!

JavaScript - Master Class
by Tomasz Ducin

Whether you’re using one or another framework... this or that library for state management… prefer either promises, async await, or RxJS for your async operations… rather sooner than later you’ll find yourself in situations where expert knowledge of the JavaScript language will be crucial to find more scalable and more performant solutions. This workshop will raise your JS skills in regards to not only the modern language specs and various usecases, but will also apply to general architectural styles and design patterns.

Advanced RxJS - Master Class
by Michael Hladky

This training will bring your RxJs skills to the next level! RxJs is more popular than ever. It is backed into the Angular core and also used in frameworks like React, Vue, and others! This doesn't surprise as it leverages a powerful and elegant way to work with sync as well as async collections. In this workshop, you will get a really deep and complete knowledge of this library. We will learn about the big and little things that make the difference in understanding! After a practical and detailed tour from creation to the destruction of observables we will work on some concepts like multicasting, custom pipes and higher order observables. As the last exercise, we will solve a couple of real-life problems in a complete example from start to end. Sounds interesting? Looking forward to meeting you at the workshop.

Unit Testing in Angular - Master Class
by David Müllerchen

We know that: you take a task in the project, complete it and continue to the next task. But how do I know if the first task is solved? Sure, monkey test. So test it manually. But what if this feature does not work anymore because of somebody else (we seldom do it ourselves)? Sure, after every commit, we'll test all the features. But that takes time. Time is money, and that after every commit. Expensive! No, a better solution are unit tests, which test the developed feature. Together with the CI, they can also be run automatically after each commit, without having to spend time on it. Let's write unit tests.

End-To-End : Distributed Systems with ASP.NET Core and Angular - Master Class
by Fabian Gosebrink

Today's distributed systems consist of front and back ends that can communicate with each other via HTTP, for example. In this workshop Fabian Gosebrink shows how to develop a user-friendly and well-structured frontend with Angular and how to provide a clean REST interface with ASP.NET Core. Using components and a modular architecture, a maintainable and scalable application is created on the client that communicates with the backend. The backend will also be developed in this workshop with ASP.NET Core from the ground up to provide the data using a REST interface. Live updates with SignalR also offer the possibility to inform the client about events without having to reload the page manually. After this workshop you will have a comprehensive impression to develop frontends with Angular and backends with ASP.NET Core so that nothing stands in the way of working on your next projects with Angular and ASP.NET Core.
