How to Use the New Animation Backend in React Native 0.85 (Step-by-Step)

React Native 0.85 quietly shipped something developers should pay attention to: a significantly updated animation backend that changes how animations are scheduled and executed under the hood.If you've been living with dropped frames on complex animated sequences, sluggish gesture response, or animations that hiccup when your app's state updates - this update is actually relevant to you. Let me walk through what changed and exactly how to take advantage of it. What Changed (And Why It Matte

Your React App Isn’t Slow — You’re Just Looking in the Wrong Place

Most slow React apps share the same hidden issues — and none of them are React itself.When a React app starts feeling sluggish, the first instinct is to blame React. Spoiler: it's almost never React. 🧠 React is not slow by defaultReact is actually very fast at what it does:It batches updatesIt uses a virtual DOMIt only touches the real DOM when necessarySo if your app feels slow, React is usually just doing extra work because we told it to. ⚠️ The real reason apps feel slowMost p

Modern TypeScript Backends: Hono, ElysiaJS, and What Comes After NestJS

Why We Stopped Starting New Projects with NestJSNestJS is a great framework. We've built enterprise systems on it (Vendure is NestJS under the hood, and we love Vendure). But for new standalone backend services, we've moved to Hono. Not because NestJS is bad. Because Hono is better for the way we work now.The shift happened gradually. We started a new API service, considered NestJS, and asked ourselves: do we need decorators, modules, providers, and the Angular-inspired dependency injectio

War Story: We Had an XSS Attack Because of a React 19 Unsafe InnerHTML UsageIt started as a normal Tuesday morning for our frontend team.

The Context: Why We Used innerHTML in the First PlaceOur portal included a rich text editor for support agents to draft responses to customer tick

How npm Behavioral Risk Scoring Works: The Methodology Behind getcommit.dev

How Commit Scores npm Packages: The Methodology Behind getcommit.dev/auditIn October 2021, ua-parser-js was compromised. ~8 million downloads per week. npm audit showed zero issues. The structural risk — a sole maintainer controlling a widely-used package — was visible in public registry data long before anyone filed a CVE (CVE-2021-41265/CVE-2021-41266). This article explains how behavioral commitment scoring identifies that risk.When I published the supply chain risk analysis, the most c

Building an AI Coding Agent from Scratch with Claude Agent SDK

Building an AI Coding Agent from Scratch with Claude Agent SDKYou've been using Claude as a chatbot — paste code, get a reply, paste again. That works. But there's a different mode entirely: give Claude a set of tools and a goal, and let it figure out the steps itself.That's what an agent is. Not a smarter autocomplete — a loop that reads files, runs checks, makes decisions, and calls your code until the job is done.In this article, I'll walk through building a TypeScript code review agent

Amazon Product API (PA-API) in 2026: Restrictions, Alternatives, and Web Scraping

Amazon’s Product Advertising API: The Access ProblemAmazon’s Product Advertising API (PA-API 5.0) is powerful — when you can use it. The catch? You need an active Amazon Associates account with at least 3 qualifying sales in the past 30 days just to maintain access.For new developers, researchers, and startups building price comparison tools or product databases, this creates a chicken-and-egg problem: you need the API to build your product, but you need sales (from a product you haven’t b

I Stopped Letting GitHub Copilot Invent My React Standard. Here Is What I Did Instead.

Every React project has a standard.The question is not whether one exists. The question is who defined it.For a long time I did not think about this. I opened a session, wrote a prompt, reviewed the output, moved on. The project grew. The codebase grew. And somewhere along the way I realized that the standard GitHub Copilot had been applying was not mine. It was whatever made sense to the AI in that moment, in that session, with whatever context it had available.Different sessions. Different dec

Stop Ruining Your SEO: Next.js Image Optimization Explained ⚡

The SEO Penalty of Bad UIIn our previous article, we discussed breaking out of the "Google Sandbox" using Programmatic SEO. But getting Google to crawl your site is only half the battle. If your platform suffers from poor Core Web Vitals, Google will actively penalize your search rankings. The two most common offenders in modern web development are LCP (Largest Contentful Paint) and CLS (Cumulative Layout Shift).These metrics are almost always destroyed by one thing: poorly managed images. If a

Configuring ReactJS in Rails with Webpacker

Modern Javascript uses a lot of libraries and processing tools, including NPM, Yarn and Webpack. So when you use React, you need all these tools. Rails has had the asset pipeline for a long time and used Sprockets as the main tool.Since Rails 5.1 there's an alternative to Sprockets for Javascript: Webpacker. In Rails 6.0, Webpacker became the default. It uses Webpack to compile all your Javascript files.One of the big advantages of Webpack is that, in your development environment, it offers live
