Deploying Machine Learning Models to the Web

Bolaji Ayodeji

One essential and last phase of the CRISP-DM data framework is deployment. The key focus in this phase is the usability of the developed model by intended users or customers. Depending on the type of solution and use case, this can involve deploying and integrating the model on any medium like the web, a mobile application, a hardware-embedded system, etc. While this might ""sounds easy,” many beginner ML engineers find it daunting to deploy their projects on the web for their intended users to test and for their solutions to solve their users' problems.

In this workshop, Bolaji will introduce you to ML model deployment by showing you the steps and processes involved with turning a machine learning model into an API with Python and Flask, testing the API with Postman, building a web application, and deploying it to the cloud for global usage. We would also discuss several other alternative frameworks and tools you can consider.

Hydration, Islands, Streaming, Resumability… Me, Oh My!

Matheus Albuquerque

Our ecosystem can be overwhelming! First, we had the rise of SSR and SSG—and each had its own gigantic pile of frameworks and tools. Then partial hydration enabled us to hydrate only some of our components on the client, which we've seen in React Server Components.

But what about islands? Do they relate at all to Streaming SSR? Moreover, what is resumability, and why do I keep hearing about it? […] Oh, did anyone say rendering on the Edge?

Well… There are many approaches out there, and all of them argue that their philosophy is best. In this session, we’ll go over these architecture/rendering patterns, to help shed some light on how some are implemented and the concepts behind them.

Friday 17:05 - 17:40 -

All you need is a contract…

Daniel Afonso

How many times have you had to wait for your backend team to finish building the API so you can start your tasks? What if all you needed to move that task to in progress was the API contract? What if there was a library that did this for REST and GraphQL APIs and, at the same time, taking your tests to the next level?
Join me and prepare to enhance your developer experience while learning all the battle-earned experiences of using one of my favorite libraries: Mock Service Worker.

Why I Still Choose React

Chance Strickland

It’s been 10 years since a small team at Facebook pitched this wacky idea to the greater JavaScript community that ultimately changed the way we all write and think about software on the web. Its core proposition—that UI should be expressed as a function of state—has stood the test of time.

In the years since, we’ve seen continuous efforts to move to the next thing, with brilliant engineers shipping capable alternatives and new modes of thinking about UI. In this talk I’ll explain why I believe React is still the right bet, why its mental model remains a thing of beauty, and why it will continue to grow in a sea of frameworks for years to come.

Processes, StateCharts and WorkFlows

Mattia Manzati

Every application has some business logic that lives across multiple requests, sessions, and sometimes this logic may even take multiple days between mutiple interactions or actors before completing.
Login workflows, Warehouse processes, wizards inside our applications, the examples are everywere.
Is this just a backend problem? Not at all! Even in the frontend and in react applications we have workflows. And what happens if one of the steps fails? And if the process needs to be shutdown?
In this talk well discover together and explore the different solutions to implement long running processes in JavaScript by using statecharts, event sourcing and generators and see pros and cons of each approach.
I'm sure you'll go back home knowing how to identify long running processes, and various ways to implement those in your application.

Resumability in the next generation frontend framework With O(1) loading time

Ruby Jane

Qwik is a JavaScript framework that uses a new rendering paradigm called resumability. It can serialize a JavaScript app into HTML, thus eliminating the need for the hydration technique used in meta-frameworks like Next.js. Is Qwik the world's first O(1) JavaScript framework? Let's find out.

I will teach you how to start with Qwik on this topic. We will cover the following topics: What is Qwik framework, Qwik vs. React, Qwik vs. Angular, How to make JS bundle smaller, and how to get started building with Qwik.

server-reason-react is an implementation of react-dom/server and some of React's internals in OCaml. Its purpose is to render HTML markup from the server for a Reason React application natively.
This talk provides an overview of some of the concepts of the library, what it means to render React in OCaml, how we use it at, a benchmark against a Node equivalent, and the future of all of this.

Bye-bye, weeds! Digital Gardening with Astro & MDX

Kathleen McMahon

Has your once-thriving digital garden become overgrown with weeds? Has your framework of choice changed from a suite of landscaping tools to a warehouse of industrial farming equipment? What if you're three versions behind? Do you upgrade and continue with complexity, or choose a new stack that meets your static site needs?

This talk will teach you to weed out site complexity with Astro, SolidJS, and MDX. Pair this with accessibility best practices, and breathe new life into your digital garden.

Rendering Dilemma: Reacting to State Change

Atila Fassina

React has exploded in popularity thanks to the performance and unrivaled developer experience the virtual DOM and reconciliation could offer. But as our apps grew, we started pushing the boundaries of managing client state in a performant way. Recently Signals have caught attention and curious eyes of developers that wish by default fine-grained control of how their applications re-render based on user actions. Let's have a look at the difference and how to achieve similar results with each paradigm.

Making state management intelligent

David Khourshid

Managing state is complicated. Humans are even more complicated. As developers, it's our job to deliver seamless and intuitive user experiences, but the sheer complexity of human behavior and the real world can make this a daunting task. In this talk, we'll explore a radical new approach to app development where language models (LLMs) and reinforcement learning (RL) can be used to handle app logic in a more intelligent and human-centric way. We're bringing artificial intelligence to state management in ways that go much, much further than existing methods. You will learn how you can leverage AI in your existing code to create the best UX possible, and peer into the future of AI and the path to AGI.

Building Machine Learning Models on Edge with React

Shivay Lamba

Ever got frustrated typing the `as` prop in React components? How about this in combination with `forwardRef`? To put it short: It's not easy. Let's delve into strategies for constructing Compound Components, Polymorphic Components, and Components wrapped in forwardRef, while avoiding the use of type casts and ensure precise TypeScript typings.

Imperative vs Declarative: Weathering the storm

Kyle Simpson

You've no doubt heard the terms "imperative" and "declarative" before, and you probably know that developers strongly prefer the latter whenever possible. But just how clear are you on what these really mean, when it comes to writing lines of code in your app? Most of us probably just wing it or feel "I know it when I see it."

Debates have raged for decades on this topic. In this talk, I'll drive straight into the eye of the storm and try to sift through what it all means for our apps. We'll look at how these concepts play out in a variety of webdev technologies, from HTML, to CSS, to JS, to (yes!) React... and more along the way. I hope you've brought your raincoat!
