Build Privacy focused React Applications with Ollama, NextJS/React and LangChainJS

Shivay Lamba

Today, most of the AI applications send data to LLM cloud providers like OpenAI, raising privacy concerns. This talk an alternative and privacy focused way to build AI applications by running LLMs locally with Ollama that keep everything local on your computer. This approach allows to avoid sending sensitive information to external servers. The talk also highlights LangChain's ability to create versatile AI agents capable of handling tasks autonomously by creating embeddings for the data. So come learn how can you build the next gen, privacy focused React application powered by Local LLMs.

The talk covers the following topics:

1.Overview of cloud-based LLMs privacy issues and the importance of running Local LLM inferencing.

2.Detailed insights into generating embeddings with tools like Ollama and demonstrating how LangChain agents can perform tasks such as document summarisation and API interactions, all while maintaining data privacy in a NextJS / React application.

3.Discovering practical use-cases for this approach.

Composition is King

Chance Strickland

React has been through some major changes in its 11-year run. From classes to hooks, from the client to the server, some folks feel like they don’t recognize it anymore. I think if we look a bit closer we’ll see that the heart of React never been more stable, and it’s still all about component composition. In this talk we’ll explore how newer features like Suspense and server components build upon familiar core concepts, offering a more composable way to build across the stack.

Friday 9:35 - 10:10 -

Enhancing Forms with React Server Components and React 19

Attendees will gain insights into practical strategies for integrating RSC into forms, focusing on enhancing user experience and reducing front-end complexities.

Friday 10:10 - 10:45 -

Debugging JS and React

Mark Erikson

As developers, we spend much of our time debugging apps - often code we didn't even write. Sadly, few developers have ever been taught how to approach debugging - it's something most of us learn through painful experience. The good news is you _can_ learn how to debug effectively, and there's several key techniques and tools you can use for debugging JS and React apps.

In this talk, we'll look at:

- Core principles and steps for approaching debugging
- How to use both print logging and GUI debugging tools effectively
- Specific tips for debugging JS code
- Approaches and techniques for debugging React components and Redux logic

A Schema is all you need!

Mattia Manzati

Whenever you are receiving data for your APIs, or just reading it from some local storage, you can't assume anything. Sure you had your beautiful typescript typings, but at runtime they are gone.
That's why people use tools like zod to ensure the incoming data is fine.
But then you have to encode back the data to send or store. And thats additional work using other libs and code.
And maybe now you need to also provide open api description for your API request body and update that as well. And that's other code as well.
And maybe you need to version your request body to support multiple versions of the input? And that other code.
And maybe your backend is not written in javascript and you need to keep updated definitions of two different languages.

Don't you agree this is a complete mess? Are we doomed?

Let's see together how @effect/schema is able to help with all of that with a single centralized point of defining your data schema's, and automatically provides functionalities such as encoding/decoding/parsing and even allows us to write custom interpreters to build tools that for example generates JSON schemas or custom code for your structures! We can even define models that accepts older versions of the structures and automatically updates them to the latest one!

All with a single centralized data schema definition.

Evolving Game Development with Genetic Algorithms

Kevin Maes

Inspired by nature, genetic algorithms have existed for decades but they, along with other evolutionary algorithms, are seeing renewed interest and practical application as ML and AI push our industry forward. When it comes to game development, for entertainment or education, it can be challenging to adapt content to players of varying skill levels. In this talk, we’ll explore how genetic algorithms are great for this and how you can use them when programming games in a React project. See strategies in action as they solve problems, enhance player engagement and continuously evolve game experiences.

Type-Safe React with OCaml: A Practical Guide

Dillon Mulroy

In this talk, we'll explore how OCaml, with its robust type system, can be used
alongside React to create type-safe web applications. We'll introduce Melange,
a compiler that seamlessly compiles OCaml to idiomatic JavaScript, a
comprehensive set of React bindings in ReasonReact, and demonstrate how to
adopt this setup incrementally. Attendees will learn about the differences in
developer experience between using React in OCaml and TypeScript. They'll also
learn how to interface with JavaScript libraries using foreign function
interfaces (FFI). We'll also cover testing strategies and essential tooling to
streamline your development workflow. By the end of this session, you'll have a
practical understanding of how to leverage OCaml and Melange to enhance type
safety in your React projects.

Full Stack Form Validation with React Server Actions

Evyatar Alush

Forms are at the core of web development, but working with them can also be challenging. As they get more complex, they become harder to write, maintain, and validate effectively.

Introducing a new way of writing forms, using Vest - a new breed of validation framework that changes the way we handle form validation using the declarative and expressive syntax and style of testing libraries.

We will cover the history of forms on the web, why it is so hard to validate them - and how to fix that. We will together step up our form validation game by taking a complex validation scenario and make it simple using Vest.

The Illusion of Success: When Delivering on Time is not Everything

Paulina Chojnowska

In the world of software development, meeting deadlines is often considered the primary indicator of a project's success. Teams work hard to ensure timely delivery, celebrating their achievements once the project is completed. But is meeting deadlines truly enough to deem a project successful?

During my talk, I will explore the shortcuts often taken to achieve timely delivery, as well as their hidden costs. These shortcuts range from working excessive hours and compromising work-life balance to damaging team relationships and accruing technical debt. I would like to highlight the importance of comprehensive project management, emphasizing that success should be measured not just by the launch but by the entire process.
