P.01Svelte 5's runes replace the old magic variable tracking with explicit reactive primitives. A year into production use, here is what changed, what improved, and what surprised us.
P.02Playwright has become the dominant web scraping tool, but the tooling decision is the easy part. Here's a practical guide to scraping that works, and the legal and ethical lines you need to know before shipping.
P.03Expo Router brings file-based routing to React Native, the same pattern web developers know from Next.js. Here's how it works, what it gets right, and where the friction still lives.
P.04While the JavaScript ecosystem chased Bun, Deno, and edge runtimes, Fastify quietly became the production choice for high-throughput Node.js APIs. Here's why it's still the right call for many teams.
P.05Phoenix LiveView lets you build real-time, interactive UIs with server-side Elixir and minimal JavaScript. Here's how it works, where it shines, and what you give up compared to React.
P.06async/await syntax makes Python code look concurrent. The behavior when you get it wrong is harder to predict than most tutorials explain. Here's what breaks in production and how to fix it before it does.
P.07Pydantic v2 shipped with a Rust-based core that made validation 5-50x faster. But the performance is only part of it — the v2 model redesign changes how you structure validation logic for complex APIs.
P.08SolidJS is not React with a different syntax. It compiles to real DOM operations, skips the virtual DOM entirely, and has a different mental model for reactivity. Here's what that means in practice.
P.09Three.js makes WebGL accessible. React Three Fiber makes Three.js feel like React. Together they're the fastest path to interactive 3D on the web. Here's how to actually use them.
P.10TanStack Router brings full TypeScript inference to URL params, search params, and loader data. Here's what that looks like in practice and when it's worth adopting.
P.11Images are the single biggest factor in Largest Contentful Paint for most sites. AVIF has widespread browser support now. Here's the optimization stack worth using and how to implement it.
P.12XState v5 ships a rewritten API that's smaller, faster, and easier to read than v4. Here's how state machines actually help in production UI, and what the migration looks like.
P.13Cursor's rules system lets teams encode their architecture decisions, naming conventions, and coding standards into the AI's context. Here's how to set it up so every engineer gets consistent suggestions.
P.14Alpine.js lets you add dropdown menus, modals, tabs, and form behavior directly in HTML without a build step or a JavaScript framework. Here's when that's exactly what you want.
P.15Deno 2 ships with full Node.js compatibility, npm support, and a revised standard library. Here's what that means for teams evaluating it as a serious Node alternative.
P.16TypeScript 5.0 shipped support for the TC39 Stage 3 decorators proposal. It's different from the old experimentalDecorators, more useful, and now the way to actually write decorators.
P.17CSS @layer lets you define explicit ordering between your reset, base, components, and utility styles. Here's how cascade layers work and how they simplify stylesheet architecture.
P.18ElysiaJS gives Bun apps fast routing, request validation, and full type inference between server and client — without code generation. Here's how it works and when to use it.
P.19Redux is overkill for most React apps. Zustand and Jotai cover 90% of real state management needs with a fraction of the boilerplate. Here's when to use each and how they actually work.
P.20An Architecture Decision Record captures why a technical choice was made, not just what was decided. One page per decision, stored in the repo, reviewed in PRs. Here's the format and how to make it stick.
P.21ESLint 9 made flat config the default and deprecated the old .eslintrc format. If your project is still on the legacy config, here's what changed, why it's better, and how to migrate without breaking your setup.
P.22Git hooks enforced by Lefthook, Husky, or lint-staged can stop broken code, style violations, and type errors before they reach your CI pipeline. Here's how to build a hook setup that teams actually keep.
P.23Adding multi-language support to a React app is straightforward when you pick the right library for your setup. Here's how react-i18next, next-intl, and Lingui differ, and which fits each project type.
P.24Most background job solutions require you to run and monitor a Redis instance, manage worker processes, and wire up your own retry logic. Inngest skips all of that. Here's how it works and when it's the right call.
P.25Three real authentication options for Next.js apps, with different trade-offs on control, cost, and setup time. Here's what each one actually involves.
P.26Rails 8 ships Solid Queue, Solid Cache, Solid Cable, and Kamal 2. Together they make it possible to run a production app on one server, without Redis, without a separate Node process, and without external managed services for the basics.
P.27Bruno keeps API collections as plain files in your repository. No account, no cloud sync, no vendor lock-in. Here's how it compares to Postman and why teams are switching.
P.28Git worktrees let you have multiple branches checked out simultaneously in separate directories. No stashing, no context switching, no 'just a second while I save my work.'
P.29Three headless CMS platforms used by agencies, three different bets on where content management is going. Here's how Sanity, Payload, and Contentful actually compare when you're building for clients.
P.30HTTP/3 replaces TCP with QUIC, a UDP-based protocol that eliminates head-of-line blocking and handles packet loss better. Here's when that matters, when it doesn't, and how to enable and verify it.
P.31Three viable paths to cross-platform mobile in 2026. Which one makes sense depends on your team, your deadlines, and how much of the device you actually need.
P.32Command-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.33The 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.34Most slow queries come from a small set of fixable problems: missing indexes, N+1 patterns, and over-fetching. This is the practical diagnostic and fix guide.
P.35Storybook 8 is faster and less painful to configure than it used to be. More importantly, the workflow shift it enables — building components in isolation — solves real problems on real teams.
P.36NestJS 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.37AI 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.38WebGPU 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.39Standardized 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.40Three 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.41Manifest 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.42Local-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.43Three 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.44Two 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.45Every agency project with a marketing team needs a CMS. The options have changed a lot. Here's how Sanity, Contentful, Strapi, and Payload stack up on the criteria that actually matter.
P.46Row Level Security moves data isolation into the database where it belongs. Here's how to set it up for a multi-tenant SaaS, handle common edge cases, and avoid the traps that break it.

P.52How Zod became the standard for runtime type validation in TypeScript apps — API contracts, form validation, environment variables, and the patterns that make schemas a source of truth across your stack.
P.53Most 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.54Stripe's API surface has grown well beyond checkout forms. Here's the realistic breakdown of which Stripe products matter for agency work, which are overkill, and where teams consistently get burned.
P.55Media 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.56If 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.57The implicit flow is dead, and most tutorials still teach it. Here is how authorization code flow with PKCE actually works, how tokens should be stored, and where most SPA auth implementations go wrong.
P.58Google'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.59PWAs 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.60JavaScript 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.61Vuex 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.62Hono 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.63Interaction 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.64Client state is easy. Server state — data that lives on a backend, changes over time, and needs to stay in sync — is where most React apps make a mess. TanStack Query handles it without ceremony.
P.65CSS Anchor Positioning lets you position one element relative to another using only CSS. No Popper.js, no JavaScript positioning logic, no layout recalculation on scroll. Here's how it works.
P.66gRPC has been available for years but many teams default to REST without thinking through the tradeoffs. Here's how gRPC works, where it fits, and where it doesn't.
P.67k6 is a developer-friendly load testing tool with JavaScript scripting, CI integration, and clear metrics. Here's how to write meaningful load tests, interpret the results, and catch performance regressions before they reach production.
P.68Tauri 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.69shadcn/ui is now the default starting point for React UIs. Here's what it actually is, why copy-paste beats npm install, and how to use it without accumulating a mess.
P.70HTTP caching is one of the highest-leverage performance optimizations available, and one of the most consistently misunderstood. Here is how it actually works, why stale content happens, and how to design a caching strategy that does not surprise you in production.
P.71Breaking API changes are inevitable. How you handle versioning determines whether clients trust your platform or avoid integrating with it. Here's a practical comparison of URL versioning, header versioning, and content negotiation.
P.72Running totals, rankings, moving averages, lag and lead comparisons: window functions handle the analytics queries that would otherwise require application-side loops or multiple round-trips. Here's how they work.
P.73Drizzle 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.74Tailwind v4 moves configuration from JavaScript to CSS, drops the content array, and ships a faster engine. Here's what the breaking changes actually mean for a real project migration.
P.75Biome 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.76Code-first API development produces documentation as an afterthought. OpenAPI-first flips that: you write the spec, generate the server stubs and client SDKs, and enforce the contract at every layer. Here's how it works in practice.
P.77Not 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.78Every public API needs rate limiting, but the algorithm you choose shapes the user experience and the failure modes. Here's how each approach works and when to use it.
P.79Most 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.80HTTP/3 is in production at every major CDN and supported by all modern browsers. Whether it actually helps your application depends on factors most guides don't explain.
P.81Video 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.82A short, direct answer to 'how much is website development' with bracket ranges by project type, the four levers that move the price, and where to read the deeper breakdown.
P.83Five different things people mean by 'update' (content, dependencies, performance, design, full rebuild) and how often each should actually happen.
