TypeScript Ninja - Master Class (stationary & online)
by Tomasz Ducin

Have you ever experienced getting a non-obvious compiler error, such as "[...] is a subtype, but could be instantiated with a different subtype", which you struggled to understand? Beyond both the basic and advanced topics, there's still a lot to learn about Generics, Recursive Types, Mapped and Conditional Types - and many constructs that make heavy use of all of them. This is a 100% hands-on workshop filled with lots of exercises which require to think in types, apply set theory to types, and, last but not least, write lots of generics, sometimes hardcore ones.
If you consider yourself a mid or senior, but you feel you could step up with your skills, this TypeScript workshop is just for you.

Building Fast WebApplications - Master Class (stationary & online)
by Miško Hevery

Building instant-on web applications at scale have been elusive. Real-world sites need tracking, analytics, and complex user interfaces and interactions. We always start with the best intentions but end up with a less-than-ideal site.
Let's look into the anatomy of a slow site and dissect it to find out how each issue got there and why fixing it is not a trivial exercise. Understanding the problem is the first step. Next is to think about possible solutions to prevent this.

Agenda:
- Anatomy of a slow site
- JavaScript over time: it is here to stay, and it is getting bigger
- JavaScript is single-threaded => CPUs cores are increasing
- Understanding the PageSpeed budget
- Third-party code
- Web-workers
- First-party code
- Hydration problem => front load JS
- Lazy loading problem => can't lazy-load visible components
- How can we have pull rather than push model of JavaScript
- Resumability is a possible solution => but it is hard

NgRx Store + ComponentStore - Master Class (stationary & online)
by Alex Okrushko

The synchronization of State is one of the most challenging parts in web applications. In this workshop we’ll go over what is this State and what are the problems that we are trying to solve. We’ll start with no libraries approach, pull and push-based services and then dive deeper into Global and Local state management with two of the most popular libraries designed to handle state: @ngrx/store and @ngrx/component-store.

This is a hands-on workshop. Each theoretical module is followed by exercise. Some of the topics that we will cover:
- Angular Ivy compiler
- Logic view and Render trees in Angular
- Content projection
- Templating in-depth: micro-syntax, patterns, and techniques
- Working with the Renderer
- Dynamic content rendering techniques
- DOM Manipulation techniques
- Directives API in depth

Performance and RxJS in Angular Master Class (stationary & online)
by Michael Hladky

Angular has a number of distinct performance bottlenecks to alleviate, especially in larger applications. However, even though there is information available on the web on improving performance, mostly this knowledge is limited to change detection strategy OnPush and async pipe. This for sure is only a tiny fraction of what’s possible so it’s time to raise the bar and double down on optimization efforts!
The web has never been more exciting! But it has also never been as demanding to our devices and infrastructure as it is today. Our browsers ship new features, and languages get updates only to squeeze out the last bit of performance we can get. The problem here, there are no real resources out there that would show us how to apply those optimization techniques in practice, which can be especially painful when it comes to framework-specific questions.
This talk will feature the most up-to-date information to expand your knowledge of performance optimization techniques beyond the basics. In the end, you will go home with lots of exercises to guide you and a wealth of insights to work with, impressed by how much faster your application can get.
Together we will take a closer look at what an auditing process looks like. Then, we will discuss how to read Flame Charts, learn how to navigate through the network tab, and increase our knowledge of network analysis features. Finally, we will take a spin on the brand-new Angular Performance DevTools and compare them with the original ChromeDevTools.

🎯 Takeaways
- How to record and analyze flame charts
- How to document performance issues and measure improvements
- How to detect performance bottlenecks
- Hands on with Angular’s brand new DevTools
- Blocking tasks and how to spot scripting bottlenecks
- Network analysis and improvement strategies
- Change detection strategies & IVY features
- Best & bad performance practices for modifying the DOM Structure and CSS rendering
- Runtime performance of scripting, rendering, and painting

In this session, we will take a closer look at what an auditing process looks like, discuss how to read Flame Charts, learn how to navigate through the network tab, and increase our knowledge of network analysis features.

Modern Angular Architectures: Standalone Components, Nx and More Master Class (stationary & online)
by Manfred Steyer & Michael Egger-Zikes

Wow, what a journey. This year, Angular already turns 6 years old. Of course, during these years it evolved a lot. Hence, it’s time to have a closer look to recently added modern features that allow for more modern, fresh, and lightweight architectures.

In this interactive workshop, we start with investigating the brand-new Standalone Components and migrate an existing Angular-Application to this innovation. We show how they work together with a professional Nx Workspace and Module Federation for building Micro Frontends and dramatically speeding up the build process.

Also, we discuss the new typed Forms and add it to our case study as well. Then, we develop some Nx Generators and Schematics for the Angular CLI allowing us to automate repeating and boring tasks related to the implementation of our architecture.

Furthermore, we introduce the NGRX Component Store as well as some advanced NGRX-Patterns. By the end you have a case study that shows how a modern Angular application can look like.

Technical Prerequisites for the Workshop:

a) Node.js installed
- LTS version or higher
- https://nodejs.org
b) Angular CLI
- npm install -g @angular/cli@latest
c) Test with “npm -v” and “ng v” from the command line whether npm and then Angular CLI work
d) Nx CLI
- npm install -g nx@latest
e) A modern browser like the current Chrome version
f) An IDE with Angular support like Visual Studio Code (free) or WebStorm/IntelliJ (commercial)
g) Optionally install git
- https://git-scm.com
- To clone the repo that I will provide at the begin of the workshop
- Alternatively the ZIP file download would work as well
h) We will use the following internet resources, so they need to be accessible for everyone:
- ANGULARarchitects.io (http://angulararchitects.io)
- npm Registry (https://registry.npmjs.org)
- GitHub (https://github.com)
