Introduction to Modern Web Development Tools

Web development is constantly evolving, and tools like React and Chrome DevTools are at the forefront of this change. These tools not only help developers build better applications but also improve the debugging and optimization processes. Let's explore some of the latest features and tips that can enhance your development experience.

Improving Debugging with AI Assistance

Debugging is a critical part of software development, and AI is now playing a role in simplifying this process. Chrome DevTools has introduced an AI Assistant panel that allows developers to chat with AI to troubleshoot and optimize UI components. This tool can help by suggesting style tweaks or solving issues, effectively reducing the complexity involved in debugging.

For instance, if you encounter an error in a React Stocks app, the AI can provide a summary and suggest solutions based on the context available in DevTools. This feature aims to transform the debugging journey by offering instant insights and solutions.

Extensibility and Optimization with React DevTools

React DevTools provides several features that help developers optimize their applications. One such feature is the ability to highlight updates when components render, helping to identify unnecessary re-renders and improve performance.

Server components are now supported in React DevTools, allowing developers to distinguish between client and server components easily. This aids in optimizing server-side logging and debugging server component experiences.

Experimenting with Local Overrides

Local overrides in Chrome DevTools allow developers to experiment with changes without affecting the original code. This feature is particularly useful for testing color contrast or other style adjustments. Developers can save these changes locally, which persist across sessions, making it easier to test and refine applications.

The feature also supports overriding content for XHR and fetch requests, providing the ability to mock API responses and debug pages even if the backend isn't ready. This flexibility can be a game-changer when developing complex web applications.

Performance Optimization with New Tools

Performance is a crucial aspect of web development, and Chrome DevTools offers several tools to optimize it. The performance panel now includes insights into Core Web Vitals, providing actionable data to improve user experience.

Developers can also use the new trace annotation feature to collaborate on performance optimization. This tool allows for detailed annotations on performance traces, helping teams work together to enhance application speed and efficiency.

Exploring 3D Layering and Animation Debugging

Understanding how DOM elements are layered can be challenging, but Chrome DevTools offers a 3D view to visualize this structure. This feature is especially beneficial for designing interactions and refining user experiences.

The animation inspector in DevTools enables developers to tweak animations in real-time, making it easier to adjust timing and effects. This tool supports the creation of more engaging and responsive web applications.

Conclusion

The integration of AI, performance tools, and new debugging features in Chrome DevTools and React is transforming how developers build and optimize web applications. These tools provide practical solutions to common challenges, enhancing both the development process and the final user experience. By leveraging these features, developers can create more efficient, accessible, and visually appealing applications.

Routing in React 18 brings a native app-like user experience and allows applications to transition between different environments. React Router and Next.js have different approaches to routing, with React Router using component-based routing and Next.js using file system-based routing. React server components provide the primitives to address the disadvantages of multipage applications while maintaining the same user experience. Improving navigation and routing in React involves including loading UI, pre-rendering parts of the screen, and using server components for more performant experiences. Next.js and Remix are moving towards a converging solution by combining component-based routing with file system routing.

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 🤐)

With the release of React 18 we finally get the long awaited concurrent rendering. But how is that going to affect your application? What are the benefits of concurrent rendering in React? What do you need to do to switch to concurrent rendering when you upgrade to React 18? And what if you don’t want or can’t use concurrent rendering yet?

There are some behavior changes you need to be aware of! In this workshop we will cover all of those subjects and more.

Join me with your laptop in this interactive workshop. You will see how easy it is to switch to concurrent rendering in your React application. You will learn all about concurrent rendering, SuspenseList, the startTransition API and more.

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.

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 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.
Table of contents- The different kinds of React application tests, and where component tests fit in- A mental model for thinking about the inputs and outputs of the components you test- Options for selecting DOM elements to verify and interact with them- The value of mocks and why they shouldn’t be avoided- The challenges with asynchrony in RTL tests and how to handle them
Prerequisites- Familiarity with building applications with React- Basic experience writing automated tests with Jest or another unit testing framework- You do not need any experience with React Testing Library- Machine setup: Node LTS, Yarn
