SVAR React Gantt is a customizable, high-performance Gantt chart component written in React. It offers a developer-friendly API, full TypeScript support, React 19 compatibility, and flexible CSS styling. The component supports multiple task types, dependencies, custom time scales, and light/dark themes. It is designed to handle thousands of tasks efficiently (see demo with 10k tasks). Interactive, drag-and-drop interface allows users to add, edit, and organize tasks and dependencies directly on the timeline or through a simple task edit form.

in a modern web app there are many potential causes of a performance problem: third-party JavaScript, overburdened servers, bloated assets, missing database indexes - a list as long as your arm. But decades of building for the web told me that this was a frontend problem. I could just smell it. The page looked janky while loading. And despite being the least-bad approach for web frontends today, the React ecosystem is lousy with ways for a codebase to get tangled, slow, and fishy.

Today's users expect fast, smooth experiences by default. Performance is no longer just a "nice to have"; it's a real product advantage that directly impacts retention, conversions, and revenue. The challenge is that debugging performance issues can feel overwhelming because there are so many reasons an app might be slow. In this guide, I'll share a step-by-step framework for optimizing React apps from bundle analysis all the way to server-side rendering.

The web is full of AI assistants that appear to understand application UIs, user data, and intent. In practice, however, most of these systems operate outside the application itself. When you try to build one from scratch, you quickly run into a core limitation: large language models have no native understanding of your React state, component hierarchy, or business logic.

React tutorial: Get started with the React libraryDespite the endless churn of new frameworks, React remains the quintessential reactive engine. This updated guide walks you through the fundamentals of React development, including a This is Spinal Tap variant on the canonical counter application. Sometimes, your components just need to go to 11.

Hi everyone! This week, we saw a lot of activity on X about the new AI skills system. Personally, what excited me most is the new Firefox release that unlocks interesting things for React developers. The React Native ecosystem is also super active, with many interesting releases. And I'm sure Expo 55 beta will drop just after we send our email 😅, so make sure to check their blog because it's coming soon. Don't miss the next email! As always, thanks for supporting us on your favorite platform:

How does generation work? (Does it generate source code?)Generated UIs must be secure, reusable and cacheable. As such, syntux does not generate source code. It generates a schema for the UI, known as a "React Interface Schema" (RIS). See the question below to get a better understanding. This schema is tailored to the value that you provide. It is then hydrated by syntux and rendered.

It's been another challenging week for the React ecosystem. Developers worldwide have been rushing to update their React versions to patch two new vulnerabilities. This serves as a good reminder for all of us to prioritize security during testing. Fortunately, React Native remains mostly unaffected by these threats, as Server Components aren't yet widely used in the mobile environment. We are taking a well-deserved Christmas break 🎄 so this will be our last issue until January 14th.

Apple's Liquid Glass UI for iOS 26 is getting a lot of attention. Beyond the visual hype, it is also raising questions about accessibility and usability. Developers, however, are already trying to recreate the effect for the web and mobile interfaces. On iOS, Liquid Glass is backed by a rendering engine designed to generate high-fidelity, physics-like glass patterns efficiently. Web browsers do not expose this kind of native abstraction, but we do have SVG filters, which are powerful enough to approximate the same effect.

Maintained by Meta, React is an open source resource designed to enable developers to build user interfaces (UIs) for both native and web applications. The vulnerability in question, assigned CVE-2025-55182 and dubbed React2Shell by the cyber community, is a critically-scored pre-authentication RCE flaw in versions 19.0.0, 19.1.0, 19.1.1, and 19.2.0 of React Server Components that exploits a flaw in how they decode payloads sent to React Function Endpoints.

Happy Monday 👋 and welcome to another special edition of Tech Talks Weekly! This edition includes the most-watched talks in the React and Vue ecosystem in 2025 so far. If you're interested in how this list was built, head over the last section. Get ready for a bit of scrolling, but it's worth it! With that said, expect your watchlist to grow!

At React Advanced 2025, Aurora Scharff presented Building Interactive Async UI with React 19 and Ariakit and shared how ARIAKit, an open-source accessibility library, enables developers to build custom UI components that meet WCAG standards without requiring deep accessibility expertise. The presentation showcased a practical approach to combining ARIAKit's unstyled primitives with modern React patterns to create production-ready, accessible interfaces.

When you are building a social feed, data grid, or chat UI, everything feels fine with 10 mock items. Then you connect a real API, render 50,000 rows with myList.map(...), and the browser locks up. The core problem is simple: you are asking the DOM to do too much work. Virtualization solves this by rendering only what the user can actually see. Instead of mounting 50,000 nodes, you render the 15-20 items that are visible in the viewport, plus a small buffer.

Build an AI assistant with Vercel AI Elements, which provides pre-built React components specifically designed for AI applications.

Modern web development is all about efficiency. We have libraries, frameworks, packages, AI tools, and Hooks. We need to build and ship fast. When React Hooks came into the picture, it was revolutionary. It changed the React game forever. Now, we know and use built-in Hooks like useState or useEffect, but we also know that there are custom Hooks. React is flexible enough to let developers write and reuse their own Hooks, or share them so that other developers can benefit too.

Meta is transferring React, React Native, and JSX to a new organization: the React Foundation. This foundation will become part of the Linux Foundation. The organization's purpose is to ensure that the development of the popular JavaScript framework is no longer under the direct influence of a single company. React was developed by Facebook in 2013. It has grown to become the most widely used front-end framework for web development.

React allows multiple updates to be batched together, which minimizes the number of render passes and significantly improves performance in applications. With this optimization, developers can create smoother and more efficient user interfaces by reducing the number of times components are rendered.

React Server Components (RSC) enable components to be rendered on the server, delivering HTML or serialized data to the client, enhancing application performance.

Vitest, by introducing its Browser Mode, allows tests to run in an actual browser context, enhancing reliability and realism in UI testing.

forwardRef is a React utility that allows a parent component to pass a ref through a child component to directly access the child's DOM node or instance.

The article discusses creating a typed routing navigation system for React apps, focusing on scenarios where simpler solutions replace traditional URL navigation, especially for apps like Electron.

The Container & Presentational Components pattern effectively separates logic from presentation, allowing for clearer and more maintainable code structure in React.

Goldfish Ads, established for 9 years, has developed a unique planning tool for Media Agencies and Brands to run Digital Out-of-Home campaigns.

The WebSocket protocol offers persistent, real-time, full-duplex communication between the client and the server over a single TCP socket connection.

The React View Transition API simplifies the addition of animations during page transitions, streamlining the process for developers by automatically managing DOM interactions.
