Static Site Generation Development – Fast, Scalable Static Sites

Static Site Generation (SSG): When SSR Falls Short

Static Site Generation is our answer to server-side rendering performance issues. Instead of dynamically assembling each page, we generate HTML at build time and serve it via a CDN. TTFB drops to 50 ms, server load disappears, and hosting costs decrease by up to 90% compared to SSR. This directly impacts Core Web Vitals: LCP shrinks from 2.5 s to 1.2 s. Our experience shows that SSG sites handle peak loads without additional costs.

Static Site Generation

Problems SSG Solves

Slow loading: LCP > 2.5 seconds is typical for SSR. After migrating to SSG, LCP drops to 0.8–1.2 s due to pre-built HTML and CDN delivery. High costs: An SSR site requires a server that costs several times more than static hosting. Scaling complexity: Under sudden traffic spikes, SSR servers fail, while SSG scales automatically via CDN without extra servers.

How We Implement SSG: A Practical Case Study

Tools and Stack

For most content projects, we choose Astro with a headless CMS. Astro ships zero client-side JS by default and supports React, Vue, and Svelte components simultaneously.

---
// src/pages/blog/[slug].astro
import { getCollection, type CollectionEntry } from 'astro:content';
import BlogLayout from '@/layouts/BlogLayout.astro';

export async function getStaticPaths() {
  const posts = await getCollection('blog');
  return posts.map(post => ({
    params: { slug: post.slug },
    props: { post },
  }));
}

interface Props { post: CollectionEntry<'blog'>; }
const { post } = Astro.props;
const { Content, headings, remarkPluginFrontmatter } = await post.render();
---

<BlogLayout
  title={post.data.title}
  description={post.data.description}
  publishedAt={post.data.publishedAt}
  readingTime={remarkPluginFrontmatter.minutesRead}
>
  <Content />
</BlogLayout>

A typed content schema is the foundation for automatic page generation:

// src/content/config.ts
import { defineCollection, z } from 'astro:content';

const blog = defineCollection({
  type: 'content',
  schema: z.object({
    title: z.string(),
    description: z.string().max(160),
    publishedAt: z.date(),
    tags: z.array(z.string()),
    draft: z.boolean().default(false),
  }),
});

export const collections = { blog };

Headless CMS Integration

Data is loaded at build time via API. Example with Contentful:

// src/lib/cms.ts
import contentful from 'contentful';

const client = contentful.createClient({
  space: import.meta.env.CONTENTFUL_SPACE_ID,
  accessToken: import.meta.env.CONTENTFUL_ACCESS_TOKEN,
});

export async function getProducts(): Promise<Product[]> {
  const entries = await client.getEntries<ProductFields>({
    content_type: 'product',
    order: ['-sys.createdAt'],
    limit: 1000,
  });

  return entries.items.map(item => ({
    id: item.sys.id,
    name: item.fields.name,
    slug: item.fields.slug,
    price: item.fields.price,
    image: `https:${item.fields.image.fields.file.url}`,
  }));
}

On every deploy or via a webhook from the CMS, the site rebuilds with fresh data. For 5000 pages, a build takes 2 minutes. SSG outperforms SSR by 3x on TTFB.

Which Tools Best Suit SSG?

Tool selection depends on the task. Astro is optimal for content projects, Next.js for hybrid solutions with ISR, Nuxt for Vue ecosystems. We guarantee: after SSG implementation, LCP will not exceed 1.5 s on a typical project.

Why SSG Is More Cost-Effective Than a Classic Server

SSG wins on delivery speed, cost, and reliability. The downside is a rebuild on every content change, but that is solved with webhook deployments.

How SSG Affects Core Web Vitals

SSG directly improves three Google metrics:

• LCP (Largest Contentful Paint): Pre-built HTML served via CDN with optimized images; LCP < 1.5 s.
• INP (Interaction to Next Paint): Minimal client-side JS ensures fast interactions.
• CLS (Cumulative Layout Shift): Reserved space for images and fonts eliminates layout shifts.

We guarantee: after SSG implementation, LCP will not exceed 1.5 s on a typical project.

Step-by-Step SSG Implementation

1. Analytics – audit of the current site, metrics, identification of content for SSG.
2. Design – tool selection, architecture, content schema.
3. Template development – building pages, integrating with CMS (Contentful, Sanity, Strapi).
4. Optimization – images (WebP/AVIF + srcset), SEO (sitemap, robots.txt, OpenGraph).
5. Testing – Core Web Vitals, performance, accessibility.
6. Deployment – CI/CD setup (Cloudflare Pages, Netlify, Vercel), webhook rebuilds.
7. Training – instructions for the content team and documentation.

Frontend Development with React: From Audit to Production

Bundle grew to 3.1 MB gzip — that's a real figure from a project that came to us for an audit. The cause: moment.js (72 KB) pulled locales for all 160 languages, lodash was imported in full instead of tree-shaken, and three component libraries were connected simultaneously. TTFB was excellent, but TTI on mobile was 14 seconds. Users left, conversion dropped by 40%. We rewrote the frontend: removed duplicate libraries, implemented dynamic imports, and SSR. Result: bundle reduced to 850 KB gzip, TTI to 2.1 seconds, LCP to 1.8 s.

Frontend is not about "drawing prettily". It's about performance, typing, rendering strategy, bundle management, and maintainability for years.

Why is Next.js the Standard Choice for SEO?

React is our primary UI framework for complex interfaces. Next.js is the standard choice for projects with SEO requirements or SSR. App Router brought React Server Components, streaming, and fetch with built-in caching. Real benefits: a catalog page with thousands of products renders on the server without sending filtering logic to the client, JS bundle is 30% smaller.

But App Router is a different way of thinking. "use client" must be placed consciously. A real mistake: a developer marks the entire layout as "use client" because of a single navigation state — and loses all RSC advantages. Rule: keep Server Components as high as possible in the tree, "use client" only for interactive leaf components. ISR for a catalog with 50,000 pages using ISR and CDN delivers TTFB < 50 ms for any page.

How Does TypeScript Prevent Bugs in Production?

TypeScript is mandatory on any project planned to be maintained longer than 3 months or with more than one developer. The argument "we write fast without types" works only for the first 2 weeks. After that, bugs related to undefined values appear every week.

Specific benefit: refactoring an API response — change a type in one place, TypeScript shows all places needing adaptation. Without types, a production bug appears in a week. strict: true in tsconfig.json is mandatory. noImplicitAny, strictNullChecks, strictFunctionTypes. The pain of Type 'undefined' is not assignable in development is less than Cannot read properties of undefined in production. tRPC provides end-to-end typing from backend to frontend without separate schema — changing a procedure type immediately shows places on the frontend that need fixing.

Vue 3 + Nuxt 3 — An Alternative SSR Stack

Vue 3 with Composition API offers a different development style, closer to React Hooks. <script setup> and composables make code more reusable. Nuxt 3 is a framework for Vue with SSR/SSG, similar to Next.js. useAsyncData and useFetch are built-in composables with request deduplication and hydration. Auto-imports are convenient but can confuse during debugging. Nuxt Content is a module for Markdown/MDX files, ideal for documentation.

Hydration mismatch is a specific pain of SSR in Vue and React. Solution: <ClientOnly> component for browser-only content, suppressHydrationWarning for dynamic timestamps.

Performance: Metrics and Tools

Bundle analysis is the starting point. @next/bundle-analyzer or rollup-plugin-visualizer — run before every major deployment. Goal: no page should require > 200 KB JS gzip for first paint.

Dynamic imports for heavy components:

const RichEditor = dynamic(() => import('@/components/RichEditor'), {
  ssr: false,
  loading: () => <EditorSkeleton />,
});

Editor (Tiptap, Quill, CodeMirror) are typical candidates for dynamic import. Without this, they end up in the main bundle. React DevTools Profiler for finding unnecessary re-renders. React.memo, useMemo, useCallback are targeted tools. Premature memoization of everything adds overhead without benefit. Profile first, optimize later.

Virtualization of long lists: @tanstack/virtual or react-window render only visible items. Table with 50,000 rows: with virtualization — 60fps, without — browser freezes on scroll.

State Management: Without Overengineering

For most applications, it's enough to have:

• React Query / TanStack Query — for server state (API data, caching, invalidation)
• Zustand — for global client state (lightweight, no Redux boilerplate)
• React Hook Form — for forms

Redux Toolkit is justified for very complex global state with many interactions. For most tasks, it's overkill. Recoil, Jotai — atomic approaches for independent pieces of state.

How to Choose the Right CSS and Design System?

Tailwind CSS latest version is our standard choice for new projects. Utility-first, excellent integration with component libraries (Radix UI, Headless UI), PostCSS pipeline. CSS Modules are an alternative when more explicit style isolation is needed. Radix UI + Tailwind (Shadcn/ui pattern) offers headless components with full control over styles. No dependency lock-in: components are copied into the project and fully customizable. Storybook is used for documenting the component library.

React DevTools Profiler — the official tool from the React team.

Testing

E2E tests via Playwright — for checkout, authentication, critical forms. Not for everything: maintaining a large e2e suite is expensive, so we select 3-5 key scenarios.

What's Included in the Scope (Deliverables)

Every frontend project we deliver includes:

• Source code in Git with full commit history and branching strategy
• Architecture document — component tree, data flow, routing decisions
• Component documentation – Storybook with stories for all reusable components
• CI/CD pipeline – automated builds, linting, tests, deployment config (Vercel / Netlify / custom)
• Access to staging environment during development and after launch
• Team training – 2‑3 live walkthrough sessions with your developers
• 3‑month warranty on any bugs found in production
• Performance report – LCP, TTI, TTFB, bundle size before/after

We also provide a pre‑deployment checklist covering browser testing, security headers, cookie compliance, and accessibility audit.

Estimates and Scope

Cost is calculated after decomposition into components, screens, and API integration. We use N+1 estimation: add 20% for risks.

What Does a Typical Performance Audit Reveal?

A recent e‑commerce project had LCP of 4.2 seconds and a monthly cloud bill of $3,000. After moving to edge‑caching (ISR + CDN) and eliminating render‑blocking scripts, LCP dropped to 1.1 seconds, and the bill fell to $1,800. The client recovered an estimated $12,000 per year in lost revenue from improved conversion. That's the kind of before‑after we regularly deliver.

Comparing tools: Next.js is 20‑30% faster in SSR builds than Nuxt with the same page size. TypeScript reduces production bugs by 60‑70% compared to JavaScript. A well‑structured bundle with code‑splitting cuts first‑paint JS by more than half.

We have 5 years of frontend development experience, over 50 completed projects, a team of 10 engineers proficient in React, Vue, Angular. We work with technologies described in React documentation and TypeScript. Additional information can be found in Wikipedia: React and Wikipedia: TypeScript.

What Stack to Choose for Frontend Development with React?

We compare tools by real metrics. Next.js is 20‑30% faster in SSR builds than Nuxt with the same page size. TypeScript reduces production bugs by 60‑70% compared to JavaScript. Savings on maintaining such a project can be significant due to reduced debugging time. If you need a lightweight SPA with minimal cost, React + Vite is enough. For a content site with SEO, Next.js with ISR gives TTFB below 50 ms even with 50,000 pages.
