About Brave Brave is on a mission to protect the human right to privacy online. Weâ've built a free web browser that blocks creepy ads and trackers by default, a private search engine with a truly independent index, a private ad network (opt-in!) that directly rewards you for your attention, and a browser-native AI integration focused on keeping private data private. And weâ're just getting started. Already 110 million people have switched to Brave for a faster, more private web. Millions more switch every month. The internet is a sea of ads, hackers, and echo chambers. Big Tech makes huge profits off our data, and tells us whatâ's true and whatâ's not. Brave is fighting back. Join us! The Browser AI team are building core browser features, and exploring new ideas about how the personal nature of the browser can help create the best AI experience for research and creative tasks. Brave allows the user to attach tabs, history, bookmarks and files to AI conversations. Brave also allows the user to experiment with AI joining in with its own web browsing. Weâ're looking for a new team member capable of iterating these ideas and creating beautiful user experiences for these features. UI engineers will often work with other engineers to create the end-to-end features, or develop the skills necessary to implement the entire feature themselves. Brave has an exciting UI engineering culture. We share knowledge and patterns across both teams and disciplines, overlapping closely with designers. We work with internal design systems, multiple UI frameworks, and make effective decisions on these features as a team. This role is at an exciting intersection between web UI, web browser internals, and AI possibilities. Brave is a start-up, and we have the ability to change plans quickly in response to new information or circumstances. This means that new needs can emerge on short notice, and projects are often re-mixed and adjusted in response to new input. Successful applicants will have the opportunity to influence those choices and other areas of the team. Many engineers in this role at Brave start from a frontend or full-stack background and grow into browser-level C++ feature work over time. Responsibilities will include: Implementing browser-integrated Web UI (e.g. AI conversations, browser settings, new tab page) using Typescript, JavaScript, HTML and CSS with React as well as other frameworks such as Web Components, Svelte and Lit Working with our product development team to collaborate on designs and specs and bring them to life on Brave's desktop and mobile browsers Integrating with custom browser APIs using Chromium's communications frameworks. Helping to customize the native UI provided by Chromium to add new product features and modify existing features. These UI elements include toolbars, modals, buttons, and more Delivering code which is well tested with high confidence Working alongside and learn from our experienced Chromium engineers - helping with peer reviews and helping improve our engineering processes Required experience: Strong skills building complex web apps with state management Deep knowledge of a Javascript UI framework such as React, Svelte, Vue, or native Web Components Proven expertise with CSS for building UI Commitment to various UI accessibility and localization techniques Understanding of performance impact and how both to measu

, the Turbopack team has published a detailed look into the architectural decisions that make their bundler significantly faster than existing solutions. The post, published on January 20, 2026, reveals how incremental computation forms the foundation of Turbopack's performance gains, particularly for massive Next.js applications.

The announcement details Turbopack's core architectural principle: incremental computation. Rather than rebuilding entire dependency graphs on every change, Turbopack tracks granular dependencies at the function level and only recomputes what's actually affected by changes. This approach fundamentally differs from traditional bundlers that operate at the file or module level.

The system works through a fine-grained dependency graph where each computation task (like transforming a file, resolving imports, or bundling modules) becomes a node. When source files change, Turbopack traces through this graph to identify exactly which computations need to run again. Everything else gets pulled from cache.

What makes this particularly effective for React development is how well it aligns with component-based architecture. When developers modify a single component, Turbopack doesn't need to re-process the entire module graph. It identifies the affected component, its direct dependencies, and any modules that import it—then stops. For large Next.js applications with hundreds of routes and thousands of components, this selective recomputation delivers substantial performance improvements.

The blog post also covers how Turbopack handles different types of changes differently. CSS modifications, for example, can often be hot-reloaded without triggering any JavaScript recompilation. Import changes trigger more extensive recomputation since they affect the dependency graph structure, but even then, Turbopack minimizes unnecessary work by caching transformation results.

The practical impact centers on development velocity at scale. Teams working on large Next.js applications often face frustratingly slow Hot Module Replacement (HMR) times. When every component change takes 5-10 seconds to reflect in the browser, developers lose flow state and productivity drops.

Turbopack's incremental approach addresses this by keeping HMR times consistent regardless of application size. A change in a leaf component should update just as quickly in a 1,000-component app as in a 10-component prototype. This consistency matters enormously for team productivity—developers can maintain the same rapid iteration cycle whether they're building new features or maintaining established codebases.

The architecture also enables better caching strategies. Since Turbopack tracks dependencies at such a fine-grained level, it can safely cache more aggressively. Switching between git branches, for instance, becomes faster because Turbopack can reuse cached computations for unchanged files even when the overall project state differs.

For mobile-first development, where quick iteration on UI components is critical, this speed improvement compounds. Testing responsive layouts, animation timing, and gesture interactions requires frequent code changes and immediate visual feedback. Turbopack's fast HMR enables the tight feedback loop necessary for polishing mobile experiences.

Consider a typical Next.js app with client and server components, API routes, and middleware. Here's how incremental computation changes the development experience:

When developers modify just the button text in this component, traditional bundlers might reprocess:

- CSS modules associated with the component

Turbopack's incremental computation identifies that only the component's render output changed. The addToCart import didn't change, the component's props interface didn't change, and the CSS class references didn't change. It recompiles just the component and triggers HMR without touching anything else.

Now consider a more complex scenario—adding a new prop:

Here, the component's interface changed. Turbopack detects this and recompiles:

- All files that render ProductCard (since the props changed)

- Unrelated components in the same directory

- API routes that don't import ProductCard

- Server components that don't use ProductCard

This selective recompilation becomes increasingly valuable as applications grow. In a monorepo with multiple Next.js apps sharing components, changes to shared components only trigger recompilation in apps that actually use those components.

The incremental computation model shows its strength under specific conditions. Initial builds take roughly the same time as other bundlers—there's no magic for processing files from scratch. The performance gains appear during development iteration:

- Modifying component logic without changing imports

- Adding/removing code within existing functions

- Adding new imports (requires dependency graph updates)

- Renaming exports (affects all importers)

- Modifying shared utilities (impacts many dependents)

Developers can optimize for Turbopack's strengths by structuring code to minimize cascading changes. Keeping components focused and limiting deep import chains helps the incremental computation system work efficiently.

Next.js 15 and later include Turbopack support. Enable it in development:

For existing applications, the migration is typically straightforward. Most webpack-specific configurations need translation to Turbopack equivalents, but standard Next.js features work without changes. The 

 provides migration guides for common webpack configurations.

Teams should expect some differences in behavior around module resolution and asset handling. Testing thoroughly in development before committing to Turbopack full-time is advisable, particularly for applications with complex webpack configurations.

The incremental computation architecture positions Turbopack well for future optimizations. As the system matures, expect improvements in:

- Build-time optimizations using the same incremental approach

- Better integration with React Server Components

- Smarter caching strategies across deployments

- Enhanced support for monorepo scenarios

For React developers, especially those working on large-scale Next.js applications, Turbopack's approach represents a meaningful step forward in development tooling. The focus on incremental computation addresses real pain points in the development workflow without requiring significant changes to how developers write code.

Turbopack's Lazy Bundling: Speed Through Selectivity

, a critical security vulnerability has been discovered in the React Server Components protocol, identified as CVE-2025-66478. This vulnerability affects applications using React Server Components and requires immediate attention from development teams running affected versions.

The vulnerability exists in the serialization layer of React Server Components, specifically in how server-rendered component props are transmitted to the client. The flaw allows potential exploitation through carefully crafted payloads that can bypass security checks during the deserialization process.

This isn't just another routine security patch. The React Server Components architecture fundamentally changed how data flows between server and client, introducing new serialization mechanisms that differ significantly from traditional SSR approaches. The vulnerability targets this specific protocol layer, where component props and server actions are encoded for transmission.

The affected versions span multiple framework releases that implement RSC:

- React versions 18.3.0 through 19.0.0 when used with RSC-compatible frameworks

Patched versions include Next.js 15.0.4+ and React 19.0.1+, along with backported fixes for earlier major versions still in active support.

The immediate concern centers on applications that use server actions or pass complex objects as props to server components. The vulnerability specifically affects scenarios where user input flows through server components without proper validation at the protocol level.

Consider a typical server action pattern:

The vulnerability doesn't stem from the application logic itself, but from how the RSC protocol handles the serialized data before it reaches your server action. An attacker could potentially craft malicious payloads that exploit the deserialization process.

Mobile developers using React Native with RSC-compatible frameworks face similar concerns, though the attack surface differs slightly due to the native bridge layer. Cross-platform applications that share server component code between web and native need to ensure both environments receive the patched versions.

The RSC protocol uses a custom serialization format that differs from standard JSON. It needs to handle special types like promises, server references, and component trees that traditional serialization can't represent. This custom format introduced edge cases in the deserialization logic.

The vulnerability likely exists in how the protocol handles circular references or deeply nested structures. Developers familiar with prototype pollution attacks in JavaScript will recognize similar patterns here. The deserialization process could be tricked into creating objects with unexpected properties or prototype chains.

Here's what a safer implementation pattern looks like after patching:

While this validation helps at the application layer, the protocol-level fix prevents exploitation before your code even executes.

Teams need to audit their server components for patterns that accept complex user input. Priority should go to:

1. Server actions that parse JSON from form data - These directly expose the vulnerable deserialization path

2. Dynamic imports in server components - If user input influences what gets imported

3. Third-party libraries that use RSC - Check if dependencies need updates too

The mobile-first perspective adds another dimension. React Native applications using frameworks like Expo with RSC support need coordinated updates across both the native app bundle and backend infrastructure. This isn't a simple npm update situation for mobile teams.

For applications in production, the mitigation path depends on your deployment setup:

Edge runtime deployments need special attention. If you're using Vercel Edge Functions or Cloudflare Workers with RSC, ensure your edge runtime versions also receive the security patches. The edge environment uses different serialization optimizations that might have distinct vulnerability characteristics.

The patched versions maintain backward compatibility for most use cases, but teams should test thoroughly. The serialization format changes might affect:

- Development tools that parse the RSC protocol

- Testing utilities that mock server components

For teams that can't immediately upgrade due to other dependencies, temporary mitigations include:

- Implementing strict input validation at every server action entry point

- Adding rate limiting to server action endpoints

- Monitoring for unusual payload patterns in server logs

- Restricting server component usage to internal, authenticated routes only

These mitigations don't fix the underlying vulnerability but reduce the attack surface while teams coordinate upgrades.

React Native developers using Expo Router with RSC features need to consider the native build cycle. Unlike web deployments that can update instantly, mobile apps require:

1. Updating the JavaScript bundle (can be done via OTA updates)

2. Potentially updating native dependencies if the fix touches native modules

3. Submitting new builds to app stores if native changes are required

The good news: most RSC implementations in React Native run entirely in the JavaScript layer, so OTA updates through Expo Updates or similar services should suffice for most teams.

Developers should prioritize this update in their sprint planning. The critical severity rating indicates active exploitation potential, making this more urgent than typical dependency updates.

For detailed technical information and official patch notes:

Monitor your framework's GitHub repository for additional security advisories, as the RSC ecosystem continues to evolve rapidly. Security researchers will likely discover related issues as they investigate the protocol more thoroughly following this disclosure.

React Native Security: CVE-2025-66478 Explained

Animation libraries have become essential tools for creating engaging user interfaces in React applications. While Framer Motion has dominated the React animation space for years, Motion One emerged as a lightweight alternative that challenges the status quo. Both libraries offer declarative APIs and powerful animation capabilities, but they take fundamentally different approaches to solving the same problems.

The most significant difference between these libraries lies in their underlying architecture. Framer Motion builds on top of React's component model, providing a comprehensive animation framework tightly integrated with React's lifecycle. The library weighs in at approximately 32KB minified and gzipped, which includes its entire feature set.

Motion One takes a different path. Built on the Web Animations API (WAAPI), it provides a framework-agnostic core that React bindings wrap around. The base Motion library is just 4KB, while the React-specific @motionone/react package adds another 2KB. This architectural decision results in a dramatically smaller footprint—roughly 85% smaller than Framer Motion.

The bundle size difference matters most for mobile applications and sites where every kilobyte counts toward performance metrics. Teams working on content-heavy sites or mobile-first applications often find Motion One's smaller footprint compelling.

Framer Motion provides an extensive API surface with specialized components for different use cases. The motion component can wrap any HTML element or React component, offering props like whileHover, whileTap, whileInView, and gesture controls out of the box.

Motion One provides a more minimal API focused on core animation primitives. While it doesn't include built-in gesture handlers, it integrates well with libraries like @use-gesture/react when those features are needed. The philosophy centers on keeping the core small and composable.

Both libraries leverage hardware-accelerated CSS properties when possible, but their performance profiles differ in specific scenarios. Motion One's reliance on WAAPI means animations run on the compositor thread by default when animating transform and opacity properties. This provides consistent 60fps animations with minimal JavaScript overhead.

Framer Motion uses its own animation engine that provides more control over timing and complex animation sequences. The library includes features like automatic layout animations and shared element transitions that require JavaScript-driven calculations. For simple animations, the performance difference is negligible. Complex orchestrations or layout animations show where each library's strengths lie.

The layout prop in Framer Motion automatically animates position and size changes, even when triggered by content changes or DOM reflows. Motion One doesn't include this feature natively, requiring developers to implement layout animations manually using FLIP techniques or similar approaches.

Framer Motion ships with sophisticated spring physics that feel natural and responsive. The spring animations automatically adjust their duration based on the distance traveled and provide realistic motion that responds to interruptions mid-animation.

Motion One takes a different approach to springs. The library uses the spring easing function from Motion, which approximates spring physics using duration-based animations. While this doesn't provide the same physics-based interruption handling, it performs better and integrates seamlessly with WAAPI.

Framer Motion's variant system provides powerful tools for coordinating animations across multiple elements. Variants define named animation states that can propagate through component trees, enabling complex choreography with minimal code.

Motion One doesn't include a built-in variant system. Developers working with Motion One typically manage animation states through React state and props, which provides more explicit control but requires more boilerplate for complex orchestrations.

For React Native applications, Framer Motion offers framer-motion-3d and works with react-native-reanimated through community adapters, though support varies. The library wasn't designed with React Native as a primary target.

Motion One's architecture makes it web-specific—it depends on WAAPI, which doesn't exist in React Native. Teams building cross-platform applications need separate animation solutions for native platforms, though the imperative animate function from Motion can work with custom drivers.

Mobile web performance differs between the libraries. Motion One's smaller bundle and WAAPI foundation typically provide better performance on lower-end mobile devices. Framer Motion's JavaScript-driven animations may cause jank on devices with limited processing power, particularly when animating multiple elements simultaneously.

Choosing between these libraries depends on specific project requirements. Framer Motion excels in applications requiring sophisticated animation orchestration, layout animations, or gesture-driven interfaces. The comprehensive API reduces the need for additional libraries, and the variant system simplifies complex animation sequences.

Motion One suits projects prioritizing bundle size and performance. Applications with simpler animation needs, content-focused sites, or progressive web apps benefit from the minimal footprint. The library requires more manual work for advanced features, but this explicitness can lead to more maintainable code in some contexts.

Both libraries integrate well with modern React patterns. They support concurrent rendering in React 18+, work with Server Components (with appropriate client boundaries), and provide TypeScript definitions. Neither library causes hydration mismatches when used correctly, though both require care when animating on mount to avoid flickers.

The landscape of React animation libraries continues evolving. Framer Motion remains the go-to choice for feature-rich applications where animation is central to the user experience. Its comprehensive API, excellent documentation, and active community make it reliable for production use.

Motion One represents a compelling alternative for teams conscious of bundle size and performance. The library's minimal footprint and WAAPI foundation provide excellent performance characteristics, particularly on mobile devices. However, developers should expect to write more code for advanced features that Framer Motion handles automatically.

The choice ultimately depends on project constraints. Applications with complex animation requirements benefit from Framer Motion's batteries-included approach. Projects prioritizing performance and bundle size, or those with simpler animation needs, find Motion One's lightweight architecture advantageous. Both libraries have earned their place in the React ecosystem, serving different needs within the animation space.

Framer Motion vs Motion One: Mobile Animation Performance in 2025

I've been building data-heavy mobile apps lately and spent way too much time evaluating table libraries. The React ecosystem has some solid options, but they're wildly different in approach. Let me break down what I've learned from actually shipping these in production.

TanStack Table (React Table v8): The Headless Powerhouse

TanStack Table is what React Table became after v7. It's completely headless, meaning zero UI components included. At first this felt like extra work, but honestly? It's perfect for mobile-first development where you need total control over rendering.

The core philosophy here is that TanStack handles the state management and logic while you handle every pixel of the UI. This makes it incredibly flexible but requires more initial setup.

The API is hook-based and composable. Want sorting? Add getSortedRowModel(). Need filtering? Toss in getFilteredRowModel(). I've found this modular approach keeps bundle sizes reasonable - you only ship what you actually use.

The mobile catch: On smaller screens, traditional tables suck. With TanStack's headless approach, I can easily switch to card layouts or accordions based on viewport width without fighting against built-in styles. The same table logic works whether I'm rendering a desktop grid or mobile cards.

Performance-wise, it handles 10k+ rows without breaking a sweat if you enable virtualization. The column pinning feature is surprisingly smooth even on mid-range Android devices.

AG Grid is what you reach for when your PM says "we need Excel but in the browser." It's massive, feature-complete, and honestly overkill for most mobile apps. But sometimes you need that firepower.

The free community version is already packed with features. The enterprise version adds stuff like row grouping, aggregation, and server-side operations that become essential at scale.

Here's the thing about AG Grid on mobile: it's not really built for it. The default experience on a phone is pretty rough. You can make it work with custom cell renderers and responsive column definitions, but you're fighting the library's desktop-first assumptions.

Where AG Grid shines is when you have power users who need to manipulate large datasets. The Excel-like filtering and sorting is incredibly powerful. I used it for an admin dashboard where users needed to export filtered data to CSV - that worked beautifully.

Bundle size is the elephant in the room. The community version adds ~150KB gzipped to your bundle. Enterprise is even larger. For mobile-first apps, that's a tough sell unless you really need those features.

React Data Grid: The Modern Middle Ground

React Data Grid from Adazzle (formerly known as react-data-grid) hit a sweet spot for me recently. It's less opinionated than AG Grid but more batteries-included than TanStack Table.

The built-in row selection, inline editing, and column resizing work out of the box. No configuration hell. The frozen columns feature is genuinely useful when you need to keep an identifier visible while scrolling horizontally.

Performance is solid up to about 5k rows without virtualization. Beyond that, you'll want to implement pagination or infinite scroll. The library uses CSS Grid internally which makes the rendering pretty snappy.

Mobile support is decent but not amazing. The touch interactions work, but you'll need custom CSS to make it truly mobile-friendly. I ended up hiding certain columns on mobile and adding a details modal for the full data.

Material React Table: When You Need MUI Integration

If you're already using Material-UI, Material React Table (MRT) is worth considering. It's built on top of TanStack Table but adds MUI components and a bunch of features out of the box.

MRT gives you a ton of features with minimal config: global search, column filters, density toggle, fullscreen mode. The MUI integration means everything looks consistent with your existing design system.

The downside? Bundle size is hefty since you're pulling in both TanStack Table and MUI components. I measured around 200KB gzipped for a basic table. That's a lot for mobile users on slow connections.

The mobile story here depends entirely on how well MUI's responsive components work for your use case. The built-in density toggle helps - switching to compact mode makes tables more usable on smaller screens.

For mobile-first apps, I default to TanStack Table. The headless approach lets me build exactly what I need without fighting against desktop-centric defaults. Yeah, it takes longer to set up initially, but the flexibility is worth it when you need to switch between table and card layouts.

For admin dashboards or internal tools where users are on desktop, AG Grid is hard to beat if budget allows for the enterprise license. The feature set is unmatched.

React Data Grid hits a nice balance for projects that need something quick but customizable. I used it for a recent project where we needed inline editing and it saved days of development time.

Material React Table makes sense if you're already deep in the MUI ecosystem and need tables that match your existing design system. Just watch that bundle size.

The real trick is matching the library to your actual requirements. Don't reach for AG Grid if you just need to display 50 rows with basic sorting. And don't torture yourself with a fully custom TanStack implementation if React Data Grid gives you 90% of what you need out of the box.
