P.01Astro 7.0 shipped a full Rust rewrite of its compiler, a jump to Vite 8, and a default markdown parser switch, plus a short list of breaking changes. Here's what changed, what got removed, and a practical checklist for upgrading a real project.
P.02Webhooks push data to you the moment something happens; polling has you ask repeatedly whether anything changed. Here's how to decide which fits your integration, plus real code for both and the hybrid pattern most production systems actually need.
P.03Vite 8 replaced its dual esbuild/Rollup setup with Rolldown, a Rust-based bundler, as the default. Here's what actually changed, the real build-time numbers, and how to tell if migrating pays off for your project.
P.04Idempotency keys let a client safely retry a request that might have already succeeded, without double-charging a card or double-creating an order. Here's how the pattern works, with a real implementation against Postgres and Redis.
P.05An N+1 query bug turns one page load into hundreds of database round trips. Here's what causes it, how to spot it in Django, Rails, and Prisma, and the eager-loading fixes that make it go away for good.
P.06OAuth handles authorization, OIDC adds identity on top of it, and SAML is the older enterprise SSO standard that still runs a lot of the corporate world. Here's how to pick the right one without reading three RFCs.
P.07Astro 6.4 ships a pluggable markdown pipeline and Sätteri, a Rust-based processor that measurably speeds up builds on content-heavy sites. It also can't run your remark or rehype plugins yet. Here's when the trade is worth it.
P.08TC39 is standardizing signals as a native JavaScript primitive, the same reactive pattern already inside Vue, Solid, Angular, and Preact. It won't ship in browsers for years, but it changes what's worth building a library around today.
P.09FastAPI merged a significant router internals refactor on June 14, 2026, followed by app.frontend() for serving SPAs a week later. Routes are now preserved instead of cloned, dynamic route registration works, and serving a React or Vue frontend from FastAPI no longer requires a workaround.
P.10The State of JavaScript 2025 survey results landed in March 2026. 25,000+ responses, and the picture it draws is less 'everything is changing' and more 'the things that work are consolidating.' Vite at 98% satisfaction. TypeScript exclusive for 40% of developers. React dominant but contested.
P.11TC39 finalized ECMAScript 2026 with eight proposals at the March 2026 plenary. Temporal gets the headlines, but the rest of the spec (Iterator Helpers, new Set methods, Promise.try, RegExp.escape, and Float16Array) is worth understanding too. Here's what ships and when you can use it.
P.12Deno 2.9 ships deno desktop — a way to turn any web project into a native, distributable desktop app with no Electron boilerplate. Here's what it does, what it's good for, and when to keep using Tauri or Electron instead.
P.13Svelte 5 runes changed the reactivity model in ways that matter for hiring. The talent pool is small but experienced. Here's how to find, screen, and evaluate Svelte developers.
P.14Next.js 16.3 preview landed June 25 with Instant Navigations — a set of tools that give server-rendered Next.js apps the snappy feel of a client-side SPA. Here's what changed, what it's built on, and when to use it.
P.15The three major frontend frameworks have all matured significantly and all make different tradeoffs. This is how we help clients choose — and why there is no universally right answer.
P.16TanStack Start hit 1.x stable and is now closing in on Next.js in weekly downloads. Here's an honest comparison of both frameworks — what each is good at, where each falls short, and how to make the call for your project.
P.17WordPress powers 43% of the web, but 'WordPress developer' covers everything from theme configurers to block API engineers. Here's how to find someone who can actually build what you need.
P.18Phoenix LiveView is production-ready for real-time web applications. Here is what it enables, where it fits, and why teams choosing it are not making an exotic choice.
P.19Frontend developer means different things to different teams. This guide covers the core screen: HTML semantics, CSS fundamentals, Core Web Vitals, and how to test for real skill rather than framework familiarity.
P.20Laravel 12 is a very different framework than the one people picture when they dismiss PHP. This is a practical look at the stack, the tooling, and when an agency or product team should reach for it.
P.21Rails 8 changed the deployment and infrastructure story significantly. A developer who has kept up looks different from one working off 2019 knowledge. Here is what to screen for.
P.22Full-stack means different things to every team. This is a practical guide to defining what you actually need, running a screen that catches specialists in disguise, and knowing when a generalist is the right call.
P.23Svelte 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.24Playwright 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.25Phoenix 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.26The OWASP API Security Top 10 lists the most critical API vulnerabilities. Most are fixable with straightforward code changes. This guide walks through each one with real examples.
P.27SolidJS 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.28Three.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.29TanStack 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.30Images 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.31XState 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.32Cursor'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.33Most web apps are missing four or five headers that would neutralize entire classes of attack. Here's what each header does, what to set, and why most defaults leave you exposed.
P.34Alpine.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.35Deno 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.36TypeScript 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.37CSS @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.38ElysiaJS 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.39Redux 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.40An 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.41ESLint 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.42Git 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.43Adding 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.44Most 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.45Three 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.46Rails 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.47Three 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.48HTTP/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.49Three 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.50The 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.51Storybook 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.52WebGPU 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.53Three 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.54Manifest 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.55Local-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.56Three 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.57Two 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.58Every 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.59A growing class of AI agent frameworks can control a browser the way a human does — clicking, typing, navigating. Here's what works in production, what breaks, and when to actually reach for these tools.
P.60Go has real strengths for backend API work, and some persistent limitations. Here's what teams actually gain and give up when they choose it over Node.js or Python for web APIs.
P.61A hands-on comparison of Typesense, Meilisearch, and Algolia for production SaaS search in 2026 — covering self-hosting, performance, pricing, and real implementation patterns.

P.63A practical guide to building SaaS billing with Stripe in 2026 — covering subscription plans, the Meter API for usage-based pricing, webhook reliability, and the Customer Portal.
P.64A practical guide to transactional email for web apps in 2026 — comparing Resend, Amazon SES, and SendGrid, with a focus on SPF/DKIM/DMARC setup and the common deliverability mistakes teams make.
P.65How 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.66Most 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.67Password resets, invoices, and notification emails are infrastructure. Most developers treat them as an afterthought until a client asks why their welcome emails are disappearing. Here is the full picture.
P.68Stripe'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.69Media 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.70If 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.71The 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.72Google'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.73PWAs 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.74The 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.75Hono 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.76Interaction 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.77Client 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.78CSS 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.79shadcn/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.80HTTP 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.81Breaking 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.82Tailwind 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.83Code-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.84Not 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.85Every 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.86Passkeys are no longer an experimental feature. Apple, Google, and Microsoft all support them natively. Here's what WebAuthn actually looks like in code and when passkeys make sense for your app.
P.87Most 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.88HTTP/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.89Video 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.90The honest read on web developer demand after AI's impact, which roles are hot, which are cooling, and what the working week actually looks like across employment types.
P.91Real revenue, profit margins, and owner take-home for solo, boutique, mid-size, and enterprise web agencies, including the messy parts most income reports skip.
P.92A 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.93Five different things people mean by 'update' (content, dependencies, performance, design, full rebuild) and how often each should actually happen.
P.94When proximity actually matters, when it doesn't, and how to evaluate local agencies without falling for the 'we have an office in your city' theatre.
P.95How to choose a B2B website agency that can support long buying cycles, multiple stakeholders, and demand generation outcomes.
