In this workshop, we’ll explore how to manage application configurations directly in your Git repository and integrate them into the TypeScript type system. The goal is to make your code aware of the actual configuration at compile-time, reducing the need for runtime validation and unit tests.You'll discover:How to create lossless types for static dataTechniques to eliminate unnecessary code paths and reduce runtime validationHow to leverage utility types to extract specific information from configurationsKey TypeScript operators and how to handle common pitfalls when working with generic typesBest practices for improving type safety and developer experienceBy the end of this workshop, you'll have a solid understanding of how to implement Config as Code in your TypeScript projects, enhancing maintainability, type safety, and autocomplete support. This workshop is ideal for TypeScript developers looking to optimize their code and streamline configuration management.

You just shipped a new feature. Tests passed. CI’s green. Everything’s deployed. Life’s good… until the alerts start rolling in. Users reporting “weird stuff happening”, UI glitches, vague “it seems slow” reports, and that dreaded “can’t login” message. Well, this is shaping up to be a bad day. But… maybe not.Watch this hands-on session to learn how to build it, break it, debug it, and go from “no idea what’s wrong” to fixing issues—all in one go. Since we’re serious developers (obviously), we’ll use Next.js and:Setup Sentry from the ground up - including Errors, Session Replay, and TracingLearn ways to use Replays to understand the real user experience, and how to use Tracing to debug application issuesLeverage Sentry AI and the context of your application to understand what’s actually broken, and use Autofix to generate a fix - from root cause all the way to PR.Use this workshop guide to follow along: Quickstart Guide.

Tests first, code last!How to develop your frontend that the code isn't falling apart? How to make it scary free to deliver your work results? How to battle bugs that are chasing you at every step you make?I am going to answer these questions during the workshop and show how to follow TDD at React applications.To showcase the approach I am going to use Cypress, React, MobX, and even Dev Containers. These tools can be replaced by others that are in use in your projects today. Here and now tooling is not so important.In spite of the title the workshop is going to be useful not only for frontend developers. You can benefit from it even working in a different area of development because the key here is a mindset of how to make reliable applications through testing.

React and its ecosystem grows every year. New tools, new patterns, new concepts. This workshop covers the latest trends in the React development world. If you feel that you know how to use it but there is something more you could learn, this workshop is for you. We'll be going through the fundamentals, composition patterns, state management, styling workflows, routing, server-side rendering and components.

In this workshop, we'll go beyond the fundamentals and explore some of the more powerful features React Query has to offer. You'll gain a deeper understanding of how it works under the hood and learn how to write scalable, maintainable React Query code.Together, we'll build a simple example app and incrementally enhance it with one core objective in mind: delivering the best possible user experience. That means snappy interactions, minimal layout shifts, and avoiding unnecessary loading spinners wherever we can.To achieve this, we'll dive into advanced techniques like various forms of prefetching (including integration with route loaders), seeding the query cache, crafting smooth paginated experiences, and even persisting query state through full page reloads using persistence plugins.
Note: You should have prior knowledge about React Query if you attend this workshop.

Malicious code is out to get you. Can you keep your app working as expected and hold on to your secrets? Come to this workshop and try!The entire workshop will be delivered as bite-sized hands-on exercises where increasingly advanced threats are presented and you get to defend. 
No matter if you're concerned with malicious npm packages or building software to run other people's code, techniques presented in this workshop can be used to isolate JavaScript at runtime and protect against prototype poisoning.
We'll explore techniques allowing cooperation with packages that intend to steal your secrets and mess with built-in functionality of JavaScript via prototype-poisoning.Another part of the workshop will focus on using tools to isolate code and scale the defensive coding practice up for larger codebases.
If you're not dealing with security-critical code, it's a great opportunity to expand your awareness of rarely explored areas of JavaScript knowledge.

In the past few years, there have been a large number of generative AI use cases and adoption has grown increasingly. A large number of web and JS applications now leverage large language models (LLMs), vector search / RAG (Retrieval Augmented Generation) for building better user experiences. Now the tide is shifting, and we have entered the era of AI agents. This is a promising field which combines the different generative AI usecases and helps to simplify the process of interacting with Gen AI by essentially making agents act like humans and makes interactions feel more human like to solve problems in an automated fashion.In this workshop, while we give a quick over view of LLMs, RAG, we will dive deeper into concepts of AI Agents such has how one can leverage LLMs for specific tasks. How can we include tool calling / function calling in AI Agents. Thus showing how an AI Agent is a system that is capable of independently deciding which functions or data sources to used to efficiently execute users' orders.We will show how to develop an AI agent that runs purely on the browser vs running them using cloud.  This workshop is for javaScript developers, AI enthusiasts, and tech innovators who want to integrate the use of AI within web applications to create intelligent and interactive app experiences.
