P.01Command-line tools are underrated as developer products. TypeScript makes them maintainable. Here's the full picture: argument parsing, interactive prompts, output formatting, and distribution.
P.02The Date object has been broken for 30 years. Temporal is its replacement, now shipping in browsers and Node.js. Here's what actually changed and how to use it.
P.03NestJS has been growing quietly for years. If your Node.js backend is a pile of Express middleware with no clear structure, NestJS offers a path forward without changing languages.
P.04AI tools write code fast. TDD asks you to slow down and write tests first. These two impulses seem to be in tension. Here's how they actually work together.
P.05WebGPU is now available across Chrome, Firefox, and Safari. It's not just a graphics API. It's a general-purpose GPU compute layer that changes what's possible in a browser tab.
P.06Standardized commit messages unlock automatic changelogs, version bumps, and release notes. Here's the full setup — from writing commits to shipping releases without manual steps.
P.07Three different approaches to styling a web application — Tailwind, CSS Modules, and CSS-in-JS libraries — and the team contexts where each one actually makes sense.
P.08Manifest V3 changed how Chrome extensions work. Here's what actually matters for developers building extensions today: service workers, declarativeNetRequest, and the gotchas nobody warns you about.
P.09Local-first means your app works offline and syncs when connected. The technology (CRDTs and sync engines) is mature enough to use. The question is whether your use case actually needs it.
P.10Three animation options dominate web development right now: CSS, Framer Motion, and GSAP. Here's how to pick the right one for your project and why the native platform is better than you might expect.
P.11Two browser APIs that used to require JavaScript libraries are now available in all major browsers. Here's what the View Transitions API and scroll-driven animations can do, with working code.
P.12The command line tools most developers use today are a decade old. Here's what's replaced them and why: terminals, Git UIs, shell configuration, and the small tools that compound into significant time savings.
P.13Most E2E test suites start fast and grow painful. Playwright solves most of that, but only if you set it up right from the start. Here is what actually works in production.
P.14React Native's new architecture shipped as stable and has been default since RN 0.76. Here's what the Fabric renderer and JSI bridge replacement changed, what the migration looks like in practice, and where the remaining rough edges are.
P.15Media queries ask 'how wide is the viewport?' Container queries ask 'how wide is my parent?' That shift changes how you think about reusable components.
P.16If your design system needs to work in React, Vue, and a legacy jQuery app simultaneously, Web Components are the only native answer. Lit makes them practical to write.
P.17Google's crawler runs JavaScript, but not the same way a browser does. The gap between what your JavaScript app renders and what gets indexed is where most SPA SEO problems hide.
P.18PWAs got a second wind when iOS 16.4 unlocked push notifications and iOS 17 improved install behavior. Three years later, the gap between PWA and native is narrow enough to matter.
P.19The Vercel AI SDK has become the default for building AI features in JavaScript apps. Here is what it actually does, how its core primitives work, and where the sharp edges still live.
P.20JavaScript error handling is broken by default — exceptions are untyped, async errors are easy to miss, and side effects are invisible in function signatures. Effect TS fixes all three. Here is how it works.
P.21Vuex was Vue's state management library for years. Pinia replaced it as the official recommendation and changed how Vue apps manage shared state. Here is how Pinia works and where it fits in a Vue 3 application.
P.22Hono started as a tiny router for Cloudflare Workers and grew into the default choice for edge APIs. Here is what it does well, where it fits, and why the 'runs everywhere' claim is actually true.
P.23Interaction to Next Paint replaced First Input Delay in 2024, and most sites still haven't caught up. INP is harder to optimize because it measures every interaction, not just the first one.
P.24Tauri 2.0 added iOS and Android support while keeping what made 1.x compelling: tiny binaries, Rust backend, and native OS webviews instead of a bundled Chromium. Here's how it works and when to use it.
P.25Drizzle ORM has become the go-to choice for TypeScript projects that want type safety without the overhead of a heavy ORM. Here's how it works, how to migrate from Prisma, and when to use it.
P.26Vitest runs faster, works natively with ESM and TypeScript, and uses the same API as Jest. If you're still on Jest in a Vite-based project, here's the case for switching and exactly how to do it.
P.27Biome is a Rust-based JavaScript toolchain that handles linting, formatting, and imports in a single binary. We've been running it in production projects since late 2025. Here's what the migration from ESLint and Prettier actually looks like.
P.28Not every real-time feature needs WebSockets. Server-Sent Events handle most push scenarios with far less complexity. Here's how to choose, and what each approach looks like in actual code.
P.29Most E2E test suites break as fast as the features they cover. Here's how to write Playwright tests that hold up when the UI changes, the data changes, and the team keeps shipping.
P.30Video calls, live collaboration, real-time audio — features clients want more than ever. WebRTC makes them possible, but the gap between a working demo and a production deployment is wider than the documentation suggests. Here's what that gap looks like.
P.31EditorPickBun hits 52K req/sec, Deno 2 achieves full npm compatibility, and Node.js remains the enterprise standard. A practical comparison with benchmarks, code examples, and migration guides.
P.32EditorPickWe have built production apps with all three. Here is an honest comparison of Next.js 15, Astro 5, and Remix covering performance, DX, and when to use each.
P.33Our curated list of npm packages that make it into every CODERCOPS project. Each one battle-tested across 30+ production apps with alternatives we considered.
P.34Vue 3.6 introduces Vapor Mode, compiling templates directly to DOM operations and skipping the virtual DOM entirely. We break down the benchmarks, the tradeoffs, and what this means for the vdom debate.
P.35Anders Hejlsberg announced the Go-based TypeScript compiler in March 2025. With TypeScript 7.0 on track for mid-2026, early benchmarks show 10x faster type-checking. We unpack what this means for your projects.
P.36Vite started as a dev server experiment by Evan You. In 2026, it is the default build tool for nearly every major framework. We trace how it won, what the modern JS toolchain looks like, and where Webpack fits now.
P.37Remix 3 drops React for a Preact fork and web-standards-first architecture. Here's why this matters, what it means for React developers, and whether the post-React era is truly upon us.
P.38jQuery 4.0.0 dropped on January 17, 2026 -- the first major version in nearly a decade. Here's what's new, why jQuery still matters, and who should care about this release.
P.39A CVSS 10.0 remote code execution vulnerability in React Server Components has been actively exploited in the wild. Here's the full breakdown of React2Shell, the follow-up DoS CVE, patching guidance, and lessons for React developers.
P.40EditorPickFrom AI-first development to meta-frameworks dominance, discover the key trends shaping web development in 2026 and how to stay ahead of the curve.
P.41EditorPickA comprehensive guide to React 19's new features including Server Components, Actions API, React Compiler, and the new hooks that are changing how we build React applications.
P.42TypeScript 5.8 brings improved type checking, direct Node.js execution, and better JavaScript interoperability. Here's everything developers need to know.
