🧠 One Framework to rule them all?

And Serverless Servers

Hey guys!

Today, I’m sharing the latest in React, including a new framework called One for web and native apps, a quick guide to building a web app with Cursor IDE, and a JavaScript refresher for React beginners. Plus, learn why PostHog engineers do support and how it makes them better, and check out Bobae Kang's blog on Vercel’s serverless servers.

Let's get into it! 🤙

⚡️ The Latest In React 

🆕 A new React framework unifying web, native and local-first
One is a new React framework built on Vite, designed for both web and native apps. It offers universal, typed routing across static, server, and client pages, making development smoother. It’s an innovative approach to handling data.

👨‍🏫 Remote Workshops: Advanced React Patterns and Remix (ad)
ReactTraining offers public remote workshops every month and coming up next week will be Advanced React Patterns (one full day) and Remix (one full day). Come explore new React 19 features along with some of the best design patterns in React on Thursday, Oct 17th. Then on Oct 18th we'll we covering one of the hottest React frameoworks, Remix and how it's will be unified with React Router 7 to create the best of SPA and MPA apps all in one framework.

🏗️ Build a web app in 1 hour with Cursor
In this guide, you’ll build a web app from scratch using plain English in the AI-powered Cursor IDE. Cursor streamlines coding in complex projects, making instant changes across files. With this React+TypeScript+Vite+MUI template, run it locally, customize it, and deploy to the web effortlessly.

🧑‍🎓 JavaScript Refresher for React Beginners
Mastering React starts with a strong grasp of modern JavaScript, especially ES6+ features. This guide covers key JS concepts to build your foundation before diving into React.

👐 Doing support makes you a better engineer
At PostHog, product engineers do support, logging into Zendesk to respond to users, debug issues, and ship fixes. While many engineers push back, saying it interrupts focus or takes too much time, PostHog believes support is key to building a better product, and makes engineers stronger in the process.

Serverless Servers and the challenge of new React architecture

I'm sharing another great blog post from Bobae Kang, this time about Serverless servers. Recently, Vercel announced a new feature: serverless servers with in-function concurrency for Node.js in Vercel Functions. This upgrade allows each function instance to handle multiple requests concurrently, leading to a 50% reduction in compute costs for some users.

While the term "serverless servers" sparked plenty of memes, the real innovation lies in how it optimizes Node.js execution. Previously, each function created an isolated instance, inefficiently waiting for async calls. Now, it forwards requests to existing instances, making the process much more efficient, particularly for Next.js apps using React's new server-client architecture.

This blog from Bobae underscores the growing synergy between React’s full-stack vision, Next.js, and Vercel’s infrastructure. As React pushes more server-side data management, Vercel’s in-function concurrency is key for handling increased server traffic efficiently.

See you next week!
