#web development

ReactJS is wildly popular and thus wildly supported. TypeScript is increasingly popular, and thus increasingly supported.

The two together? Not as much. Given that they both change quickly, it's hard to find accurate learning materials.

React+TypeScript, with JetBrains IDEs? That three-part combination is the topic of this series. We'll show a little about a lot. Meaning, the key steps to getting productive, in the IDE, for React projects using TypeScript. Along the way we'll show test-driven development and emphasize tips-and-tricks in the IDE.

In this workshop, you'll learn how to build your first full stack dapp on the Ethereum blockchain, reading and writing data to the network, and connecting a front end application to the contract you've deployed. By the end of the workshop, you'll understand how to set up a full stack development environment, run a local node, and interact with any smart contract using React, HardHat, and Ethers.js.

TL;DR: CMS Migration Numbers That Tell the StoryMost website migrations fail the same way: rankings drop, traffic disappears, and recovery takes months. The teams that avoid it don't get lucky — they treat CMS migration services as an engineering discipline, not a one-time technical event. The difference between a migration that compounds into growth and one that unravels six months post-launch comes down to how early SEO planning enters the process.The headless CMS market reached $816M in 2024 and is growing 22% annually, with 73% of enterprises already adopting headless architecture. As more companies move to API-first stacks, choosing the right CMS migration service is critical to:Preserve search rankings with proper redirects and URL mappingImprove performance and Core Web VitalsEnable faster content workflows with headless CMSReduce long-term CMS costs and vendor lock-inThis guide reviews the best CMS migration service providers in 2026 to help you migrate safely — without traffic loss or technical debt.Migrate a Website-Growing TrendAnalysts now expect the majority of digital teams to move away from page-based suites toward composable, API-first stacks in the next 2-3 years. As brands add channels, markets, and campaigns, traditional CMS workflows start to crack: content is duplicated per site, templates are hard to change, and every new experiment needs a developer. Headless CMS flips that: content lives in one structured hub, feeds every channel via APIs, and lets editors ship updates without queuing behind the sprint board. When teams rush into a headless CMS migration without SEO planning, they don’t just change platforms; they wipe out the very signals search engines use to trust and rank their sites.What Is Headless CMS Migration? Migrating a website to a headless CMS means decoupling your content from how it's presented. s work in one central content hub. Developers build fast, flexible frontends in Next.js, React, or whatever the delivery layer demands for any channel: web, app, or in-product UI. The content model stays stable. The presentation layer becomes a technical decision, not a CMS constraint.That separation is the point. It's also where migrations get complicated.Your SEO won't migrate automatically. Rankings follow decisions — specifically, the ones you make before anything moves. Keep URLs as stable as possible. Build a complete 301 redirect map for every URL that changes. Crawl both the old and new versions of the site before launch to catch missing metadata, lost content, broken internal links, and orphaned pages. That decision compounds: a redirect missed at migration can take months to recover from in search.The architecture is the easy part to get excited about. The unglamorous audit work is what protects everything you've already earned.Why Go Headless? CMS Migration JustificationWhat pushes businesses to CMS migration besides the draconian price of your Contentful? Let me guess, the code quality? Security reasons? It depends.That's exactly what professional headless CMS migration services are designed to solve — handling the technical and SEO complexity so your team doesn't have to.Here are the top 9 reasons businesses seek headless CMS migration services, starting with economic ones and followed by technical website reasons:Escape runaway license costs: Legacy and monolithic CMS platforms keep increasing base subscription fees. Ballooning costs, driven by user-seat pricing and add-on charges, are turning your content stack into a fixed cost that grows faster than your traffic or revenue. This erodes ROI over time and makes staying on your current CMS increasingly hard to justify.Stop paying for “empty” overages: Many enterprise CMS contracts charge extra for API calls, environments, locales, or storage, even if you’re not using advanced features that justify the bill.Replace complex pricing with predictable value: Moving to a modern headless stack lets you choose components (CMS, hosting, search, media) that match your actual usage and budget, instead of being locked into one vendor’s bundled pricing.Reinvest license spend into growth: The money currently tied up in inflated CMS subscriptions can be redirected into content production, SEO, and experimentation that measurably drives revenue.”Future‑proof against price hikes: A composable headless architecture gives you leverage; if one vendor’s pricing becomes unreasonable, you can swap it out without rebuilding your entire site.Security vulnerabilities: Traditional monolithic CMS platforms like WordPress (when unmanaged) or aging proprietary systems are prime targets for hackers. Outdated plugins, unpatched cores, and shared databases create attack surfaces that headless, API-first architectures simply don't have.Poor performance: A slow website is a leaking revenue pipe. If your CMS is tightly coupled to your frontend, every design tweak becomes a developer ticket. Businesses migrate to gain speed, better Core Web Vitals scores, and the freedom to optimize independently.Technical debt: Years of patched plugins, custom workarounds, and legacy integrations quietly accumulate until your codebase becomes a house of cards. A full site migration is often the cleanest escape route.Lack of scalability: When your CMS can't handle traffic spikes, multiple languages, or omnichannel delivery without expensive custom work, growth itself becomes the enemy. Modern headless platforms are built to scale without breaking.The Moment Teams Start Looking for a Website Migration AgencyMost teams don't reach out to website migration companies because the technology stopped working. They migrate because the cost of staying finally outweighed the cost of moving. The CMS that made sense three years ago — reasonable at the time, familiar to the team, integrated into the workflow — quietly becomes the thing that slows every campaign, blocks every experiment, and shows up as a line item that's hard to justify at budget review.The shift is rarely dramatic. It's the accumulation of small frictions: a developer ticket for a content change that should take thirty seconds, a performance audit that points back to the platform, a pricing renewal that arrives with a number that no longer matches the value. At some point the question changes from "should we migrate?" to "what were we waiting for?"That's when the search for website migration companies begins — not in crisis, but past the point where staying is the safer option.The world of content systems has changed, just like you after Covid. While platforms like Storyblok are popular among marketers for visual editing, the best CMS depends on your team structure, developer resources, and content complexity. Alternatives like Contentful, Sanity, and Strapi may be better suited depending on the use case. We advise Storyblok for its simplicity, as it's the CMS that consistently gets the least pushback from the people who actually use it daily.

How do you move a site without significant SEO loss, and who can assist my team with CMS migration services?What should be taken into account before CMS migration?One of the most critical decisions, besides choosing website migration company, is choosing the right CMS, and for most businesses today, that means going headless. But raw headless power alone isn't enough; consider the following:CMS Flexibility: When you migrate a website, whether from a legacy platform or decide to migrate a WordPress website to a more scalable architecture, clients increasingly demand a CMS that supports diverse, flexible layouts for individual content types. Think distinct page structures for blog posts, case studies, landing pages, and product pages, all managed from a single platform without duplicating effort.Friendliness: The days of requiring a developer to publish a paragraph or rearrange a section are over. The best modern CMS platforms integrate a visual page builder directly into the interface, empowering marketing and content teams to construct, update, and iterate on pages entirely independently — a capability that WordPress alone, in its traditional form, often struggles to deliver at scale.SEO Preservation: A poorly executed migration can wipe out years of hard-earned organic rankings overnight. Careful URL mapping, redirect management, and metadata migration are just as important as the technical build itself — and should never be an afterthought.Localisation Support: For any business operating across borders, localization is no longer a nice-to-have. The ability to manage multiple languages, regional content variations, and locale-specific SEO from within the same CMS is now a baseline expectation, not a premium feature.Get these four right, and your website migration becomes a launchpad; get them wrong, and it becomes a liability.SEO Preservation: The Part That's Easy to Get WrongWebsite migration impacts SEO reasonably. Every page you've ranked took time. Every backlink pointing at a specific URL is a signal you've earned. When you migrate a website, that equity doesn't transfer automatically; it follows the decisions you make before a single line of code changes.The analogy is here: fixing SEO after a website migration is like correcting old handpoke tattoos done by an amateur. You can do it, but you're always working against what's already there. The cleaner move is to plan and protect everything upfront.That means treating SEO preservation as an engineering problem, not an afterthought.Before any migration begins, a serious team runs a full technical audit: title tags, meta descriptions, headings, and image alt text – and documents every URL in the existing site. Not most of them. Every single one. From there, a complete 301 redirect map is built, mapping each old URL to its new destination. Nothing gets left to assumptions.CMS Migration ChecklistThe pre-migration checklist that compounds into your post-launch performance:Full technical audit of the existing siteComplete URL inventory301 redirect map (old URL → new URL)Analytics baseline exportInternal linking structure documentationCurrent ranking data exportSchema markup documentationFull site backup before anything movesMiss one of these, and you're not migrating a website (CMS); you're rebuilding your search visibility from scratch. The development agencies that get this right treat the checklist above as the floor, not the ceiling.
The post-launch CMS migration checklist:Organic traffic monitoring via GA4 and Google Search Console from day one. Ahrefs if you want a second signal.Crawl error checks in the first 48 hours — redirect failures and orphaned pages surface fast if you're watching.Ranking position tracking — flag significant drops in the first two weeks. The faster you catch them, the less they compound.Metadata review in the first month — rewrite underperforming title tags and descriptions while the index is still settling.Index coverage report — confirm priority pages are being crawled and indexed correctly.This combo of technical care and content parity lets you migrate a website to a headless content management system for performance without sacrificing your past merits.Replatforming vs. Migration. Why ''just replatforming' is Not Enough“Just replatforming” is not enough because it moves your site to new tech without accurately fixing the underlying problems in content, workflows, data, and SEO. If you simply swap CMS platforms or hosting and keep the same messy content model, fragmented data, and ad‑hoc processes, you end up with the same bottlenecks. The difference is that only now they’re running on a newer, more expensive stack. A meaningful website migration is an opportunity to rethink information architecture, streamline content types and workflows, clean and normalise data, and plan SEO and analytics from the start so your team actually ships faster and your site performs better instead of “lifting and shifting” old issues into a shiny new interface.How Long Does it Take to Migrate a Website?Migrating a website is rarely a one-size-fits-all process. Migration timelines vary widely depending on the size, complexity, and condition of your existing setup. A simple CMS migration for a small site might take as little as two to four weeks, while a full global website migration involving thousands of pages, multiple languages, and complex integrations can take anywhere from three to six months. Headless CMS Migration Process and PlanningWhen you move a website from a legacy platform to a headless CMS solution, the bulk of the time goes into content mapping, URL redirects, SEO preservation, and quality assurance, not just the technical build. For instance, WordPress migrations tend to be faster thanks to a mature ecosystem of tools, but enterprise-scale projects demand far more planning. Working with a professional CMS migration service can really make a difference. Website migration team have established workflows that help lower risks, safuguard your search rankings, and minimize downtime. No matter if you need basic website migration services for a small business or a complicated content overhaul across different region for enterprise business, the key principle remains unchanged:The more thorough your plan for a migration, the smoother it will be.Top 11 Website CMS Migration Services to Future-Proof Your WebsiteHere's a list of headless CMS migration services that cater to different business needs, covering everything from consulting and maintenance to migrating custom features and integrating AI.1.

The language signals ambition but not specificity. How to Choose the Right CMS Migration ServicesNot every agency that calls itself a CMS migration partner/provider is built for the same problem. Before you shortlist anyone, check these five things:Technical stack expertise: do they know the platform you're moving to, or are they learning on your project?E-commerce experience: product data, payments, and checkout flows don't survive a careless lift-and-shiftCMS specialists vs. generic dev shops: specialists know what breaks, what compounds, and what to protectSEO-safe methodology: redirects, canonicals, ranking preservation — this should be a defined process, not improvised per projectPost-launch support: what happens at week three when something misfires? The answer tells you more than the proposal doesHeadless CMS Agencies QuickpickThis list is very general, as there is no single winner or 'best' CMS service/agency across all scenarious. Everything depends on your site architecture, team structure, and risks around SEO. With that in mind, choose:

If you're planning a migration or specifically looking for a headless CMS agency, talk to CMS migration services team. Here you can also book an SEO-safe migration audit. We'll map out exactly what needs protecting before anything moves. CMS Migration Service FAQWhat happens when you migrate a website?When you run a website migration, you move key elements like domain, CMS platform, URL structure, design, and content from one setup to another. If it’s not planned properly, this can temporarily affect organic traffic, rankings, and tracking while search engines discover and re‑evaluate your new pages.Is SEO migration necessary?Yes, SEO‑led website migration services are essential if you want to keep your existing visibility, rankings, and revenue. Without structured SEO migration work (redirect mapping, content parity, technical checks), you risk broken URLs, lost authority, indexation issues, and significant drops in traffic.Can I migrate from WordPress to a headless CMS without traffic loss? You can migrate a WordPress website to a headless CMS with minimal or no lasting traffic loss if you treat it as a full SEO website migration project. That means preserving high‑value URLs where possible, implementing page‑level 301 redirects, maintaining or improving content, and launching on a fast, SEO‑friendly front end.Do I need e-commerce CMS migration services for Shopify/BigCommerce?If you are moving an e-commerce shopfront on Shopify or BigCommerce to a headless architecture, we recommend e-commerce CMS migration services. They help you migrate product data, content, URLs, and SEO signals correctly so you can benefit from faster headless experiences without sacrificing organic traffic or conversion rates.What headless CMS is the best for a marketing team with limited dev support?Storyblok is the best CMS here, for pure editorial independence out of the box. Its visual page builder lets non-technical teams build and publish pages without a developer in the loop.

Choosing the right Next.js agency is one of the highest-leverage decisions a SaaS founder or enterprise engineering lead can make. Regardless of the type of project you plan to undertake an agency—be it a small startup, mid-market SaaS, or a large enterprise—Next.js is your sensible choice for the frontend in 2026.This guide evaluates 15 Next.js development agencies across Europe — covering technical depth, verified CMS partnerships, Vercel platform experience, and documented client outcomes — so you can identify the right Next.js developers for your specific project without relying on rankings that prioritise brand size over delivery evidence.According to the State of JavaScript 2025 survey (13,000+ respondents, sponsored by Google Chrome and JetBrains), Next.js is used by 59% of JavaScript developers, making it the most adopted React meta-framework by a significant margin. Not every agency that lists Next.js development services on their website has built production-grade SaaS platforms with it. This guide focuses on European Next.js agencies with documented delivery at scale.Many well-known companies use Next.js for various purposes, e.g., Nike, Stripe, TikTok, Uber, Wayfair, Notion, and Apple. Thanks to its performance, scalability, and developer experience Next.js works well for enterprise websites, SaaS dashboards, and high-traffic landing pages. It’s also popular for e-commerce platforms, marketing sites, and customer-facing web apps.TL;DR — Top Next.js Agencies in Europe at a GlanceBest Next.js agency for headless CMS migrations: FocusReactive (London/Warsaw) — Sanity certified, 35-domain multilingual delivery for EasyPark, clients all over the worldBest for performance engineering and App Router migrations: Blazity (Warsaw) —  70% LCP improvement for CookUnityBest for headless commerce and Shopify Plus: Naturaily (Wrocław); Shopify Plus certifiedBest for large enterprise digital transformation: Dept Agency; Contentful partnerBest for net-new SaaS product builds: Netguru or Boldare; full design-to-engineering lifecycle, strong Clutch track recordBest for custom B2B/B2C commerce platforms: Rigby; Medusa.js specialists for marketplace and multi-tenant buildsBest for design-led SMB and startup builds: Halo Lab; competitive rates, high design qualityKey buying signals to verify before committing to any Next.js development agency: App Router in production (not Pages Router), named Vercel partner status, at least one case study with a measured outcome, and a defined post-launch SLA.Who This Guide Is ForThis guide is written for a single reader: a technical decision-maker — CTO, VP of Engineering, or hands-on founder — at a mid-market SaaS company or enterprise digital team who is evaluating a Next.js development agency for one of the following Next.js projects:Migrating a legacy platform (WordPress, Drupal, AEM) to a headless Next.js architectureBuilding a new SaaS frontend or Next.js website from scratch on the App RouterScaling an existing Next.js codebase that has outgrown the original team's capacityIf you are a marketing director selecting a Webflow agency, or an enterprise procurement team seeking a 500-person outsourcing firm, this selection guide is not the right resource. The Next.js agencies listed here are specialist software engineering teams, not general digital agencies, and the evaluation criteria reflect that difference.How to Evaluate a Next.js Development Agency: 8 CriteriaThese criteria should be applied before reviewing any Next.js agency's portfolio. Outline your project needs for each criterion, then score the agencies based on your requirements — not against each other in the abstract.1. Next.js App Router and React Server Component FluencyAny Next.js agency doing serious work in 2026 should be building on the App Router by default — it is the current production standard and the only model Vercel is actively developing new features for. An agency still defaulting to the Pages Router for new projects, or that cannot clearly explain the Client/Server Component boundary, is working on a deprecated paradigm.Ask: Are your current production projects on the App Router or Pages Router? How do you decide which components are Server Components versus Client Components?Red flag: Defaults to "use client" on most components, or describes App Router as "still evaluating."2. Next.js Rendering Strategy DepthA capable Next.js agency should be able to tell you exactly which rendering strategy — SSG, ISR, SSR, or RSC — applies to each layer of your application and why, including the caching and cost implications of each choice. If the answer is "we use SSR for everything," that is not a strategy, it is a default.Ask: How do you decide between SSG, ISR, and dynamic rendering in an App Router project? How do you handle cache invalidation when CMS content updates?Red flag: Cannot explain the difference between route-level and component-level caching in the App Router.3. Vercel Platform DepthProduction Next.js deployment on Vercel goes well beyond connecting a GitHub repo — it requires managing edge middleware, environment variable scoping, preview deployments, build cost optimisation, and observability tooling. An agency that has only used Vercel's free tier has not encountered the challenges enterprise deployments surface.Ask: Have you managed Vercel enterprise accounts with multiple deployment targets? Have you configured Edge Middleware for geo-routing or A/B testing?Red flag: Cannot describe how they manage Vercel build costs or have never used Speed Insights for production diagnostics.4. Headless CMS Integration as Part of Next.js Development ServicesDeep CMS integration means designing the content model, configuring draft mode for live preview with React Server Components, and ensuring editors can operate independently after handover — not just connecting the API and fetching data. Ask for a certified partnership and a concrete content modelling example, not a list of supported platforms.Ask: Are you a certified partner of the CMS we are considering? How do you implement draft mode with Server Components for live preview?Red flag: Treats CMS setup as a configuration task with no content modelling methodology to show.5. SEO Continuity and Core Web Vitals MethodologyFor platform migrations, organic search equity is a business asset that can be destroyed by poor redirect handling or metadata loss. A qualified Next.js agency treats Core Web Vitals and URL continuity as engineering deliverables from sprint one, not as post-launch cleanup.Ask: How do you handle URL mapping and redirect implementation during a migration? Can you show pre/post Core Web Vitals benchmarks from a previous project?Red flag: Redirects are handled at the end of the project, or the agency cannot produce crawl comparisons from past migrations.6. TypeScript and Code Quality: What to Expect from Senior Next.js DevelopersThe codebase a Next.js agency delivers will be maintained by your internal team or a future agency — TypeScript by default, automated tests, and clear documentation are baseline requirements, not premium extras.Ask: Is TypeScript the default on all projects? What testing framework and coverage standards do your Next.js developers apply?Red flag: Delivers JavaScript-only codebases or has no automated testing in the handover.
ask the programmer meme7. Post-Launch Support and SLA StructureThe first 90 days after launch consistently surface redirect gaps, content model edge cases, and performance regressions. A Next.js agency without a formal post-launch support period and documented SLAs will deprioritise incidents because those hours are unscoped and unbillable.Ask: What are your SLAs for critical production bugs in the first 90 days? Is a retainer model available for ongoing work?Red flag: No formal post-launch support structure beyond "reach out if something breaks."8. Enterprise Delivery EvidencePortfolio logos are not delivery evidence — ask for case studies that name a client, describe the integration complexity, and cite a measurable outcome (Core Web Vitals score, traffic change, time-to-market). An agency that cannot provide this has not delivered at enterprise scale.Ask: Can you share a Next.js App Router case study with similar content volume or language count to our project, including the measured outcome?Red flag: Case studies show design screenshots and describe outcomes as "improved performance" without figures.How Next.js Agencies Were Ranked: MethodologyEvery agency in this list was evaluated against five factors. No agency paid for inclusion. Agencies ranked higher when they demonstrated App Router adoption in production (verified via case studies, public repositories, or technical blog content) and could show documented delivery at enterprise content or traffic scale. Agencies whose public case studies predate the App Router era, or whose documentation suggests primary reliance on the Pages Router, rank lower regardless of brand recognition or team size.FactorWeightSignal UsedApp Router and RSC adoption in productionHighVerified via case studies, public repos, or technical blog postsVercel platform depthHighOfficial partner status, enterprise account evidence, edge middleware usageSEO and Core Web Vitals track recordHighNamed platform certifications; documented content modelling approachHeadless CMS certification and methodologyHighPre/post launch metrics; migration case studies; Metadata API usageEnterprise delivery evidenceMediumNamed clients, measurable outcomes, team scale documentationAgency Comparison MatrixThe matrix below uses factual indicators rather than qualitative labels.

According to the State of JavaScript 2025 survey — 13,000+ respondents, sponsored by Google Chrome and JetBrains — Next.js is used by 59% of JavaScript developers, making it the most adopted meta-framework by a significant margin.Three structural factors explain why Next.js framework has become the default choice for SaaS and enterprise frontend development in Europe specifically.Rendering flexibility within a single framework. Next.js supports SSG, SSR, ISR, React Server Components, and Partial Prerendering within a single project. This means the same engineering team handles performance-critical marketing pages, dynamic SaaS dashboards, and API routes without switching frameworks or splitting the codebase. The App Router, now the default since Next.js 13 and stabilised through versions 14 and 15, has matured into a production-ready foundation that engineering teams are actively building on rather than evaluating.Vercel's edge network for multi-market performance. European SaaS companies typically serve audiences across multiple countries and languages. Vercel's global CDN and edge middleware configuration deliver measurable Core Web Vitals improvements over traditional hosting setups, with direct impact on organic search performance in competitive European markets.Ecosystem maturity. The Next.js integration ecosystem — headless CMS platforms such as React CMS solutions (Storyblok, Sanity, Contentful, Payload), authentication providers (Clerk, Auth.js), commerce platforms (Shopify Hydrogen, Medusa), and observability tooling — has reached a level of maturity that substantially reduces integration risk. Native App Router support for draft mode, the Metadata API, route-level caching configuration, and the Vercel AI SDK for AI-powered features means most production requirements are covered without custom workarounds.Frequently Asked Questions about Next.JS1. What is a Next.js development agency?A Next.js agency is a software engineering company that specialises in building, migrating, and scaling web applications using Next.js — the React meta-framework maintained by Vercel. Unlike a general web development agency, a dedicated Next.js agency employs developers who work exclusively or primarily with Next.js, meaning they have hands-on experience with the App Router, React Server Components, Vercel deployments, and headless CMS integrations. When your Next.js project involves performance-critical rendering, multi-language content architecture, or a migration from a legacy platform, a specialist Next.js agency will make different, and usually better architectural decisions than a generalist team that treats Next.js as one tool among many.2. What does a Next.js agency typically charge in Europe?We can't garantee the 100% accuracy, because everything depends, but. Hourly rates for specialist Next.js agencies in Western Europe (UK, Netherlands, Germany) range from $80 to $150. Central European agencies (Poland, Ukraine) typically range from $40 to $100. Total Next.js project costs for a headless CMS migration or a new SaaS marketing site range from $30,000 to $200,000+ depending on content volume, language count, integration complexity, and post-launch support requirements. A Next.js project that involves multiple languages, CMS editorial workflows, and Vercel enterprise deployment will sit toward the upper end of that range regardless of the agency's day rate.
3. What is the difference between the App Router and Pages Router, and why does it matter when hiring a Next.js agency?The Pages Router is Next.js's original routing model, where each file in /pages becomes a route and data fetching happens via getServerSideProps or getStaticProps. The App Router, introduced in Next.js 13, uses a /app directory, supports React Server Components natively, and fundamentally changes how layouts, data fetching, and caching are structured. Vercel is actively developing new features (Partial Prerendering, improved caching primitives) exclusively for the App Router. A Next.js agency still defaulting to the Pages Router for new Next.js projects in 2026 is building on a model that will require migration in the near term — and signals they are not actively working at the current production standard.4. What built-in features does Next.js provide to improve SEO?Next.js aligns its rendering and optimisation defaults with what search engines and Core Web Vitals reward, making good SEO the path of least resistance rather than a bolt-on. The key mechanisms are:SSR and SSG deliver fully rendered HTML to crawlers, unlike client-side React apps that ship an empty <div>. Search engines index pre-rendered content far more reliably.The Metadata API (app/layout.tsx or generateMetadata()) lets you define <title>, <meta description>, Open Graph tags, and canonical URLs declaratively — per page or dynamically based on route params:export async function generateMetadata({ params }) {    return {      title: `Product: ${params.slug}`,      description: "...",      alternates: { canonical: `https://example.com/products/${params.slug}` },    };  }Automatic sitemap.xml and robots.txt are generated via convention-based files (app/sitemap.ts, app/robots.ts), keeping them dynamic and always in sync with your routes.Image optimisation via <Image> enforces correct sizing, serves modern formats (WebP/AVIF), and adds width/height attributes automatically — directly improving LCP and CLS scores.Font optimisation via next/font eliminates layout shift from web fonts by inlining font-face declarations and preloading — directly improving CLS.Streaming and React Server Components reduce TTFB and improve LCP by sending HTML progressively, benefiting both users and crawlers.Structured data (JSON-LD) is injected as a <script> tag in any Server Component, enabling rich results in search.A qualified Next.js agency treats all of these as standard delivery requirements, not optional enhancements.5. What headless CMS platforms work best with Next.js in 2026?
Sanity, Storyblok, Contentful, and Payload CMS are the four platforms with the deepest documented Next.js App Router integrations. Sanity and Storyblok have native visual editing and draft mode support for React Server Components. Payload is a TypeScript-first, self-hostable CMS that can be run within the same Next.js application. The right CMS choice depends on editorial workflow requirements, content model complexity, localisation needs, and whether the team wants a hosted or self-hosted solution.6. What should a Next.js agency deliver at project close?
A production-quality handover from a Next.js agency includes: a TypeScript codebase with automated tests (unit, integration, and ideally end-to-end); documentation covering content model schema, component architecture, and deployment processes; redirect mapping validated against the pre-launch crawl; a configured Vercel project with environment variables scoped correctly to staging and production; editor training and documentation for the CMS; and a defined post-launch support period with documented SLAs for critical and non-critical issues.7. When should I hire a Next.js agency instead of a freelancer? 
A freelancer is the right choice when scope is tight, the project is well-defined, and you need one or two specific skills — a performance audit, a CMS integration, a specific component build. A Next.js agency makes more sense when the project has moving parts that require multiple disciplines at once (architecture, frontend, CMS configuration, DevOps, QA), when the stakes of getting the architecture wrong are high, or when you need continuity after launch.

The modern web would be different without rich client-side applications supported by powerful frameworks: React, Angular, Vue, Lit, and many others. These frameworks rely on client-side JavaScript, which is their core. However, there are other approaches to rendering. One of them (quite old, by the way) is server-side rendering entirely without JavaScript. Let's find out if this is a good idea and how Remix can help us with it?
Prerequisites- Good understanding of JavaScript or TypeScript- It would help to have experience with React, Redux, Node.js and writing FrontEnd and BackEnd applications- Preinstall Node.js, npm- We prefer to use VSCode, but also cloud IDEs such as codesandbox (other IDEs are also ok)

Passwordless authentication may seem complex, but it is simple to add it to any app using the right tool. There are multiple alternatives that are much better than passwords to identify and authenticate your users - including SSO, SAML, OAuth, Magic Links, One-Time Passwords, and Authenticator Apps.
While addressing security aspects and avoiding common pitfalls, we will enhance a full-stack JS application (Node.js backend + React frontend) to authenticate users with OAuth (social login) and One Time Passwords (email), including:- User authentication - Managing user interactions, returning session / refresh JWTs- Session management and validation - Storing the session securely for subsequent client requests, validating / refreshing sessions- Basic Authorization - extracting and validating claims from the session token JWT and handling authorization in backend flows
At the end of the workshop, we will also touch other approaches of authentication implementation with Descope - using frontend or backend SDKs.

In this workshop we will learn how to build a personal blog from scratch using Remix, TailwindCSS. The blog will be hosted on Vercel and all the content will be dynamically served from a separate GitHub repository. We will be using HTTP Caching for the blog posts.
What we want to achieve at the end of the workshop is to have a list of our blog posts displayed on the deployed version of the website, the ability to filter them and to read them individually.
Table of contents: - Setup a Remix Project with a predefined stack- Install additional dependencies- Read content from GiHub- Display Content from GitHub- Parse the content and load it within our app using mdx-bundler- Create separate blog post page to have them displayed standalone- Add filters on the initial list of blog posts

All beginnings are hard. Even harder than choosing the technology is often developing a suitable architecture. Especially when it comes to GraphQL.
In this workshop, you will get a variety of best practices that you would normally have to work through over a number of projects - all in just three hours.
If you've always wanted to participate in a hackathon to get something up and running in the shortest amount of time - then take an active part in this workshop, and participate in the thought processes of the trainer.

Building modern web applications is riddled with complexity And that's only if you bother to deal with the problems
Tired of wiring up onSubmit to backend APIs and making sure your client-side cache stays up-to-date? Wouldn't it be cool to be able to use the global nature of CSS to your benefit, rather than find tools or conventions to avoid or work around it? And how would you like nested layouts with intelligent and performance optimized data management that just works™?
Remix solves some of these problems, and completely eliminates the rest. You don't even have to think about server cache management or global CSS namespace clashes. It's not that Remix has APIs to avoid these problems, they simply don't exist when you're using Remix. Oh, and you don't need that huge complex graphql client when you're using Remix. They've got you covered. Ready to build faster apps faster?
At the end of this workshop, you'll know how to:- Create Remix Routes- Style Remix applications- Load data in Remix loaders- Mutate data with forms and actions

Node.js has become an increasingly popular language to build and deploy backend APIs. In a world of legacy CMSs adopting decoupled implementations, plenty of frameworks have sprung up to classify themselves as "headless" CMSs, designed from the start to provide an easy way to personalize content models, administer permissions and authentication, and serve a content API quickly.
Strapi, one of the leaders in this space, has recently released their v4 version of the framework, and with Platform.sh it can be deployed alongside a number of frontends within the same project, giving a drastically simplified development experience working with decoupled sites. In this workshop, we'll deploy a Strapi demo application, which has been configured to serve a restaurant review site.
Piece piece you will add database services, tests, and frontends, all within the safety of isolated development environments. At the end, each user will have a functioning decoupled site, and some greater understanding of working with decoupled sites in production.

In this workshop, we'll build a React app from zero to one using a GraphQL API from Nhost.

Table of contents:
- Sign up to Nhost and create a Nhost app
- Create database table
- Set up React app
- Install Nhost and GraphQL dependencies
- Display data in React app
- Let users sign in
- Add GraphQL API permissions

The Vue3 has been released in mid-2020. Besides many improvements and optimizations, the main feature of Vue3 brings is the Composition API – a new way to write and reuse reactive code. Let's learn more about how to use Composition API efficiently.

Besides core Vue3 features we'll explain examples of how to use popular libraries with Vue3.

Table of contents:
- Introduction to Vue3
- Composition API
- Core libraries
- Vue3 ecosystem

Prerequisites:
IDE of choice (Inellij or VSC) installed
Nodejs + NPM

Hasura is a free and open-source GraphQL Engine that can help supercharge your GraphQL adoption, whether it is for a new application or for an existing one. The workshop will cover:
- A basic introduction to GraphQL- Using GraphQL to make CRUD operations from a React application- Setting up access controls to data- Building real-time components in React using GraphQL Subscriptions- Wrapping existing REST APIs with GraphQL servers that can be deployed on serverless platforms, and then merging them into a single endpoint using Remote Schemas- Triggering serverless functions on database events- In short, we’ll go through how React developers can adopt realtime GraphQL and serverless.
