Top ideas

How has Redux evolved over time?

Redux has evolved from being a minimal library requiring a lot of boilerplate code to Redux Toolkit, which simplifies common tasks like creating stores and reducers, and includes features like RTK Query for data fetching. Modern React features like hooks have also been integrated into Redux.

Who is Nadia?

Nadia is a developer who has worked for a small startup and Atlassian on the product JIRA. She loves to travel and moved from Australia to Austria. Her hobbies include investigating how things work and writing about them.

How does Redux compare to using React's useReducer and useContext?

While useReducer and useContext can mimic some Redux patterns, they differ in that Redux keeps state outside the React component tree, leading to fewer re-renders and better performance in some scenarios. Redux also offers powerful developer tools not available with useReducer and useContext.

What is the new event loop in React Native?

The new event loop in React Native is part of the new architecture that allows for synchronous communication between JavaScript and native layers, improving performance and aligning React Native more closely with React DOM.

Who should consider using TanStack Start?

Businesses building React applications that require a robust client-side framework with server-side capabilities should consider using TanStack Start, especially if they value type safety and URL state management.

How does Svelte differ from React?

Svelte is HTML-first, focusing on states rather than changes between states like JavaScript does. It allows developers to use valid HTML directly in components, offering a more intuitive approach compared to React's JSX.

We surveyed thousands of developers to show that a louder audience leads to a better presentation. There has been a shift in web app development towards server-first architectures, which has improved full-stack capabilities but at the cost of complexity and divergence from the client-centric approach. Tanstec Start is a meta-framework that aims to provide the best client-side authoring experience with powerful server-side primitives. The Tansec Router supports advanced routing features, URL state management, and JSON storage. Combined with the server-side rendering capabilities of TanStack Start, it becomes even more powerful. The TanStack Router has isomorphic loaders and integrates seamlessly with TanStack Query for additional features like polling and offline support. UseSuspenseQuery allows for dynamic streaming of data during SSR. TanStack Start also offers server-side features, API routes, server functions, and middleware. The future plans include RSCs, websockets, real-time primitives, and static pre-rendering. TanStack Start is now in beta and is suitable for building React apps. It is open source.

Scaling Fast – Engineering Lessons From ~15 Years of Tech Startups
Image
Hey, we'll discuss scaling fast and engineering lessons learned in the last 15 years of tech startups. Scaling involves three things: business, team, and tech. Business scalability relies on sales and customer acquisition costs. Engineering is a tool the business uses. Scaling the team is vital as tech problems are often people problems. Team structure affects architecture and product development process. Organize teams based on purpose, not technology. Spend less time being blocked by other teams. Ship features without getting blocked. Own your own mess. Focus on product engineering partnership. Build faster using feedback cycles. Build appropriate solutions for your use case. Let go of ego and experiment with different approaches. Engineers own their own mess. Avoid work in progress. Finish the work and focus on fixing it later. Have a conversation before writing code. Scaling the tech is easier than you think. Pick an off the shelf design. Save innovation for core parts. Pick existing solutions. Focus on solving the problem. Don't waste time trying to predict future scale. Scale will surprise you. Do what works for your business. Push back on unnecessary complexity. Understand the cost of ideas. Modify the situation to fit existing design. Architecture is like a dependency graph on your code. Reduce architectural complexity by organizing code based on what it does. Use vertical models and avoid creating excessive dependencies. On the client, use vertical modules. On the back end, consider a service-oriented architecture. Start with a monolith and transition to microservices if necessary. Use folders instead of microservices when you have a small team. Use vertical models and contract or type-driven development to define clear APIs and interfaces. Avoid highly interconnected code and duplication. Focus on data structures to avoid complexity and the need for translation layers. Building translation layers can lead to slow user experience. Vertical teams aligned with vertical code allow for fast problem-solving, full control of features, and efficient data handling. Understanding the entire domain enables faster development with fewer bugs.

Taking a Dump: Using Heap Dumps to Find and Fix NodeJS Memory and CPU Problems
Image
Talking about using heap dumps to find and fix Node.js memory and CPU problems. Starting with a horror story of server crashes and memory leaks in Node.js environment. Exploring why memory leaks occur in JavaScript and how garbage collection works in programming languages. Memory leaks can occur in garbage collected environments. Understanding how garbage collection works in JavaScript and general programming languages. Exploring the mark and sweep phases of garbage collection to identify and reclaim unreachable objects. The garbage collection process involves two phases: mark and sweep. Objects not reachable from roots are marked for removal. The issue arises when objects can still be reached, causing memory leaks like with unbound caches. Memory leaks can occur due to global references or unclosed hooks causing objects to remain in memory, leading to potential memory overflow. Memory usage fluctuates due to garbage collection cycles, which prevent memory leaks by releasing unused memory. A memory leak leads to increasing memory and CPU usage, potentially causing system unresponsiveness. Pinpointing memory leaks is challenging as they affect the entire application, often appearing in production environments. Heap and memory dumps help analyze memory issues, generated in multiple ways like DevTools and command line. Exploring memory usage through Node.js application launch, debug mode, and heap snapshot analysis in Chrome DevTools. Exploring memory snapshots and pinpointing memory leaks by creating diffs between snapshots to identify leaked objects and their references for easy fixes. Exploring different methods for generating memory snapshots, including CLI flags, experimental node flags, and API usage, to efficiently identify memory leaks and manage heap dumps in Node.js environments. Discussing security considerations, challenges in memory leak detection, utilizing heap dumps for resolution, and emphasizing the importance of data security and verification in fixing memory leaks.

Lessons From Adopting React Compiler
Image
Akash Hamilwasia presenting at React Summit 2025, shares React Compiler learnings and works on an AI audio platform. Memoization in React helps optimize UI performance by preventing unnecessary re-renders. React Compiler offers automatic memoization through static code analysis. React rules emphasize purity and immutability. The compiler analyzes and memoizes code changes for optimization. React Compiler package usage improves performance through code analysis. Understanding reactivity issues is crucial for handling React state. Compiler optimization requires correct dependency arrays and usage of external libraries. Measure React Compiler impact using React Profiler for optimization and real user impact analysis.
