Sessions & Workshops

A lot technical learning opportunities ranging from introductions to deep dives, covering service and solution topics such as RxJS, TypeScript, Progressive Web Apps, NativeScript, Node.js and many more...


Sharpen the Saw

The idea is that sometimes you have to take a break from the “work” of your work to sharpen your skills. A dull axe won’t cut a tree nearly as effectively as a sharp one.

JS Workshops (January 27,2022)

10.00 - 17.00 January 27
Nir Kaufman - JS Poland

Advanced JavaScript Design Patterns and Data Structures for UI Engineers Master Class (online)
by Nir Kaufman

In this workshop, you will learn how to leverage object-oriented principles and functional programming design patterns in JavaScript. You will learn how to build modular, maintainable single-page applications. By the end of this session, you will understand the core principles beyond popular libraries (such as NGRX, RxJS, and more.), and how to leverage TypeScript for clean code.
This is a hands-on workshop. Each theoretical module is followed by exercise. We will use nothing but TypeScript (no external libraries or frameworks) and focus on practical software engineering. Some of the topics that we will cover:

- How classic design patterns can help us build modern JavaScript applications
- JavaScript built-in data structures in depth
- How to implement and leverage popular data structures in practice
- How to think, design, and implement clean code using OO principles.

Vanilla JS Performance Master Class (stationary & online)
by Michael Hladky

The Chrome DevTools are a powerful addition to the developer’s toolset that allows finding and eliminating your app’s performance bottlenecks. It is packed with features perfect for auditing page performance and deriving actionable insights. Visualizing data at a proper level of abstraction, it can help you pinpoint performance-related issues and set a baseline from which to start introducing improvements.
That said, knowing how to run performance tests on your web application properly is one thing, and putting those metrics to good use is another. Both aspects are critical to the overall success of the endeavor. Thus it is so crucial to understand all the ins and outs of performance data and performance tooling.
This might sound like a lot but don’t be put off! Over the course of this workshop, we will walk through the pitfalls and tricks of the trade of Chrome DevTools to provide you with a complete roadmap for performance analysis and optimization.
Chrome Developer Tools should be seen as a fount of knowledge about your app performance that anyone can benefit from. At that realization, the best part begins – experimenting and finding the most effective ways to improve the application’s speed.
In this workshop, we will explore the exciting hidden DevTools features and learn about:

- Web Vitals – what they are and how to measure them
- Scripting, parsing, and prioritization
- Network analysis and request debugging
- The browser’s rendering pipeline
- How to read the performance timeline
- Frame drop, and why we should care about it
- Scheduling techniques and scheduling priority
- HTML structures, their styling and rendering in a browser
- The Paint Flash APIs and scroll performance issues
- Layer composition, layer squashing, and reflow triggers
- Main thread scheduling and non-blocking UIs in Angular

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.

- Derived state (shared computations, distinct changes, and nullish values)
- Model vs. ViewModel
- OOP Design Patterns for Component state (Facade, MVVM/Presenter, MVC, Adapter)
- Subscription-less architecture
- Optimize data fetching with RxJS flattening operators
- How to handle error, complete, suspense, and values in the template

Fullstack GraphQL using Angular v12 Master Class (stationary & online)
by Gerard Sans

In this workshop we will create a Fullstack GraphQL app starting from the Server and building our way up to the client! We will cover everything you need to successfully adopt GraphQL across your stack from client to backend including tooling and best practices.
You will learn how to build and design a GraphQL Server starting by defining the GraphQL Schema using types and relations. Moving to the client side, we will create a simple client to demonstrate common usage. As we implement the different features we will introduce GraphQL query syntax including queries, mutations, alias, fragments and directives. At this point we will review how client and server communicate, what tooling is available to track usage and improve performance and how to add authorisation and authentication. Finally we will focus on designing real-time features and sharing best practices to improve performance and leverage scalability.

Topics we will cover:
- GraphQL Introduction
- Building a GraphQL Server
- Designing a GraphQL Schema
- Building a GraphQL Client using queries and mutations
- Common practices: error handling and pagination
- Adding authentication and authorisation
- Adding real-time with subscriptions

- Comfortable using Angular and JavaScript
- Basic knowldege of Node
- HTML and CSS
