Module Federation lets you organize code into federated modules, dynamically loaded at runtime within a host application—a core mechanism behind Super Apps. On the web, this is typically handled with Webpack.Now, with Re.Pack as a Metro alternative, React Native supports it too. This allows existing native Super Apps to transition to React Native and enables truly cross-platform modules, letting developers use React and JavaScript without concern for where modules run.In this talk, we’ll explore these possibilities, best practices and real-world examples to help you build efficient, cross-platform Super Apps.

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. Table of contents:  1. Intro to the general landscape of LLMs, RAG2. What are AI Agents3. Core components of AI Agents4. How to build your first AI Agent with JavaScript5.

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.

Discover how we tackled the common challenges of a large E2E test suite and made our React codebase easier to refactor.In the past year, we went from zero to 20,000 lines of Playwright tests, pushing its capabilities beyond basic end-to-end testing. This talk will explore the challenges we encountered as we scaled our Playwright setup and how we solved them, thanks to the robust ecosystem and team creativity.The talk covers:- Testing approaches and where common tools fit on the testing pyramid- Challenges scaling E2E test suites: performance, flakiness, ownership, mocking and more- How we solved these challenges to unblock refactoring a large React codebase- Advanced Playwright tips and tricks

At the Top of the Pyramid: Playwright Testing at Scale

Kate Marshalkina

As applications scale in complexity, managing user permissions becomes a growing challenge. Without a structured approach, permissions quickly become a tangled mess of if-else statements, leading to poor maintainability and scalability. While Role-Based Access Control (RBAC) provides a strong starting point for managing user access, it may not offer the level of granularity needed as your app evolves. To gain finer control over who can perform what actions, on which objects, and under what conditions, the Attribute-Based Access Control (ABAC) model, recommended by OWASP, becomes invaluable. In this session, we’ll explore two practical approaches to building a scalable permissions system in React. First, I'll introduce CASL, a popular ABAC library that simplifies fine-grained access control. Then, I'll walk you through creating a custom permissions system from scratch, offering insight into designing a solution that fits your app’s needs. Throughout the session, I'll conduct detailed code walkthroughs for both approaches, covering key concepts like optimized state management, custom hooks, and caching/conditional queries using Redux Toolkit. You’ll learn how to implement these strategies to create a clean, efficient, and maintainable permissions framework. By the end of the session, you’ll have a solid understanding of how to implement scalable permission systems in React, whether you choose a pre-built solution like CASL or build your own.

What if the architecture of our web applications wasn't solely about technological choices? Many backend architecture practices could be relevant in the frontend but remain underutilized. These practices capitalize on how our brain functions to enhance efficiency. Since we spend over 70% of our time reading code, developing the ability to read more efficiently, achievable through solid architecture practices, would be advantageous.

Prioritizing Architecture Over Framework in Web Development

Alexandre Rivest

This talk explores the architectural implications for frontend development in serverless applications. I’ll examine how the stateless, on-demand nature of serverless backends requires frontend developers to adopt new patterns and strategies. We’ll discuss how architectural decisions around distributed state management, connection handling techniques to mitigate cold starts, designing better loading experiences, implementing robust error boundaries, and adapting authentication logic impact the frontend architecture in serverless environments. The presentation includes live demonstrations of real-world implementations, such as a real-time SSE dashboard, JWT authentication, and serverless image generation. Join me to discover how frontend architecture must evolve to complement modern serverless backends.
