It doesn't matter if you're only learning ReactJS fundamentals or you're ready to boost your skills with advanced courses, the remote conferences brought a number of great presentations for everyone over the past 12+ months. We've selected the top ones available online.

React, the favorite library of web and mobile developers alike, doesn't need a long introduction. The framework has become essential for creating modern applications, and while other JS tools have expanded or revised it, React is still the one to beat. 

That's why we've compiled the following list of great conference talks from 2020/2021 – the season of COVID but also the season of awesome remote events – that will guide you through all things React, from state management to improving performance. We highly recommend that you watch these if you want to improve your next JavaScript project!

Shawn Swyx Wang: Lessons to outlive React

There was a time before React, and there will be time after it. If you tie yourself too closely to any technology, you might trap yourself and miss the next wave. So let's zoom out from the state management library 'du jour' — what timeless lessons can we learn from React? 

In the talk, Shawn Swyx Wang discusses the lessons he's learned from studying React, especially the ones that are going to stick with him for the rest of his career.

Sara Vieira: React is hard but not why you may think

React is hard. There are many resources for getting started, but things can get complex and confusing when writing full-blown applications. Navigating the React ecosystem is a lot to take in and sometimes highly overwhelming. With this talk, Sara hopes to help you understand some of its 'gotchas' more clearly while giving you some confidence when building bigger React apps.

Brandon Bayer: The dawning of a new age for fullstack React

New frameworks like Blitz.js and Redwood.js are ushering us into a new era for full-stack development. They are mixing old concepts and ideas with cutting edge technologies to make full-stack developers more productive than ever. Brandon Bayer's talk will take you on a journey through time and show you the exciting things that lie ahead.

Kent C. Dodds: Managing React application state management

Application state management is one of the hardest parts of building and maintaining React applications. One thing that makes it complicated is when you aren't thoughtful about how that state is organized and categorized in your app. There are different kinds of state, and they require different approaches for management. And when you try to treat all app state the same, that's when problems come into play. 

Kent C. Dodds' talk deals with what some of those categories are and how you can drastically simplify your application code and improve your app's performance thinking about and organizing your state differently.

David Khourshid: XState – The visual future of state management

With this talk David Khourshid, you'll learn how state modeling with state machines and statecharts can improve the way you develop your React applications. You'll also get a sneak peek of never-before-seen visual tools that will take state management to the next level.

Paul Henschel: Making games in React

Paul Henschel's talk focuses on react-three-fiber — and with his guidance, you'll be making a mini-game. You'll see how you can make it through all the heavy boilerplate and math without losing your mind, even when you're a beginner. You'll also see how to translate the process to anything, be it a game or a website with some exciting visuals and effects.

Omri Bruchim (Wix): Making your React Native app fast

In the past five years, the Wix mobile app has gone through quite a bit: a brand new look was launched, a large number of features were added in a short time, and the number of users tripled. Unfortunately, one implication of product growth is slower performance, especially when it comes to seamless transitions, fluent animations, and the general slickness of the app. 

Wix made a tremendous effort to improve these regressions, and the ongoing efforts have so far resulted in almost 60% cumulative improvement in all performance metrics. In his talk, Omri Bruchim from Wix dives deep into all of the secret ingredients for better performance in React Native applications and gives practical examples on improving startup time, responsive gestures, and preload prioritization. 

Nader Dabit: Next.js on AWS

In this video, you'll learn how to implement authentication in a Next.js app using AWS Amplify and Amazon Cognito. Nader Dabit's talk covers everything from SSR authentication, SSR redirects, protected routes, client-side redirects, and authenticating a request in an API route.

A Guide to React Rendering Behavior
React is a library for "rendering" UI from components, but many users find themselves confused about how React rendering actually works. What do terms like "rendering", "reconciliation", "Fibers", and "committing" actually mean? When do renders happen? How does Context affect rendering, and how do libraries like Redux cause updates? In this talk, we'll clear up the confusion and provide a solid foundation for understanding when, why, and how React renders. We'll look at: - What "rendering" actually is - How React queues renders and the standard rendering behavior - How keys and component types are used in rendering - Techniques for optimizing render performance - How context usage affects rendering behavior| - How external libraries tie into React rendering

Everything Beyond State Management in Stores with Pinia
When we think about Vuex, Pinia, or stores in general we often think about state management and the Flux patterns but not only do stores not always follow the Flux pattern, there is so much more about stores that make them worth using! Plugins, Devtools, server-side rendering, TypeScript integrations... Let's dive into everything beyond state management with Pinia with practical examples about plugins and Devtools to get the most out of your stores.

Using useEffect Effectively
Can useEffect affect your codebase negatively? From fetching data to fighting with imperative APIs, side effects are one of the biggest sources of frustration in web app development. And let’s be honest, putting everything in useEffect hooks doesn’t help much. In this talk, we'll demystify the useEffect hook and get a better understanding of when (and when not) to use it, as well as discover how declarative effects can make effect management more maintainable in even the most complex React apps.

React Query: It’s Time to Break up with your "Global State”!
An increasing amount of data in our React applications is coming from remote and asynchronous sources and, even worse, continues to masquerade as "global state". In this talk, you'll get the lowdown on why most of your "global state" isn't really state at all and how React Query can help you fetch, cache and manage your asynchronous data with a fraction of the effort and code that you're used to.

React Hooks Tips Only the Pros Know
The addition of the hooks API to React was quite a major change. Before hooks most components had to be class based. Now, with hooks, these are often much simpler functional components. Hooks can be really simple to use. Almost deceptively simple. Because there are still plenty of ways you can mess up with hooks. And it often turns out there are many ways where you can improve your components a better understanding of how each React hook can be used.
You will learn all about the pros and cons of the various hooks. You will learn when to use useState() versus useReducer(). We will look at using useContext() efficiently. You will see when to use useLayoutEffect() and when useEffect() is better.

React, TypeScript, and TDD
Workshop Free
ReactJS is wildly popular and thus wildly supported. TypeScript is increasingly popular, and thus increasingly supported.
The two together? Not as much. Given that they both change quickly, it's hard to find accurate learning materials.
React+TypeScript, with JetBrains IDEs? That three-part combination is the topic of this series. We'll show a little about a lot. Meaning, the key steps to getting productive, in the IDE, for React projects using TypeScript. Along the way we'll show test-driven development and emphasize tips-and-tricks in the IDE.

React Performance Debugging Masterclass
Workshop Free
Ivan’s first attempts at performance debugging were chaotic. He would see a slow interaction, try a random optimization, see that it didn't help, and keep trying other optimizations until he found the right one (or gave up).
Back then, Ivan didn’t know how to use performance devtools well. He would do a recording in Chrome DevTools or React Profiler, poke around it, try clicking random things, and then close it in frustration a few minutes later. Now, Ivan knows exactly where and what to look for. And in this workshop, Ivan will teach you that too.
Here’s how this is going to work. We’ll take a slow app → debug it (using tools like Chrome DevTools, React Profiler, and why-did-you-render) → pinpoint the bottleneck → and then repeat, several times more. We won’t talk about the solutions (in 90% of the cases, it’s just the ol’ regular useMemo() or memo()). But we’ll talk about everything that comes before – and learn how to analyze any React performance problem, step by step.
(Note: This workshop is best suited for engineers who are already familiar with how useMemo() and memo() work – but want to get better at using the performance tools around React. Also, we’ll be covering interaction performance, not load speed, so you won’t hear a word about Lighthouse 🤐)

Designing Effective Tests With React Testing Library
React Testing Library is a great framework for React component tests because there are a lot of questions it answers for you, so you don’t need to worry about those questions. But that doesn’t mean testing is easy. There are still a lot of questions you have to figure out for yourself: How many component tests should you write vs end-to-end tests or lower-level unit tests? How can you test a certain line of code that is tricky to test? And what in the world are you supposed to do about that persistent act() warning?
In this three-hour workshop we’ll introduce React Testing Library along with a mental model for how to think about designing your component tests. This mental model will help you see how to test each bit of logic, whether or not to mock dependencies, and will help improve the design of your components. You’ll walk away with the tools, techniques, and principles you need to implement low-cost, high-value component tests.
