Code Style Consistency with EditorConfig: Turnkey Setup
Imagine: five developers in a team, each using their own editor — VS Code, WebStorm, Vim. One uses spaces for indentation, another uses tabs. Git shows hundreds of changes due to space-to-tab replacements on every commit. Hours are wasted on alignment and fixing. In one real project with a team of 8, we introduced EditorConfig — and Git conflicts dropped by 95%. The .editorconfig file in the project root sets unified rules for all editors: indentation, line endings, encoding, and trailing whitespace. No more formatting disputes. EditorConfig is supported out-of-the-box in VS Code, JetBrains IDEs, Vim, Emacs, Sublime Text. For others, a plugin is available for virtually any editor. Basic setup takes 1 hour (from $100), full setup (including CI integration, fixing existing files, and training) takes 4 hours (from $400). It pays off within the first week by reducing code review time by 2 hours per week, saving approximately $200 per week for a team of 5. That's 10x cheaper than the weekly cost of manual formatting fixes.
How EditorConfig Solves Code Style Disagreements
EditorConfig works at the editor level: when a file is opened, it automatically applies the configured settings. This means:
- All developers see code with identical indentation.
- New files are created with the correct line ending (LF).
- A final newline is added automatically.
- Trailing whitespace is removed on save.
We tailor EditorConfig to your project's specific stack. For example, for JavaScript projects we use indent_size = 2, for Python indent_size = 4, for Go tabs. Below is a typical config:
# EditorConfig
root = true
[*]
charset = utf-8
end_of_line = lf
insert_final_newline = true
trim_trailing_whitespace = true
indent_style = space
indent_size = 2
[*.{js,jsx,ts,tsx,mjs,cjs}]
indent_style = space
indent_size = 2
max_line_length = 100
[*.{css,scss,less,styl}]
indent_style = space
indent_size = 2
[*.{html,htm}]
indent_style = space
indent_size = 2
[*.json]
indent_style = space
indent_size = 2
[*.{yml,yaml}]
indent_style = space
indent_size = 2
[*.py]
indent_style = space
indent_size = 4
max_line_length = 88
[*.go]
indent_style = tab
indent_size = 4
[*.php]
indent_style = space
indent_size = 4
[Makefile]
indent_style = tab
[*.md]
trim_trailing_whitespace = false
max_line_length = off
[*.{png,jpg,jpeg,gif,ico,webp,svg,woff,woff2,eot,ttf,otf,mp4,mp3,pdf,zip}]
insert_final_newline = false
trim_trailing_whitespace = false
Verification and CI Integration
EditorConfig itself does not format existing files. To check and automatically fix violations, we use editorconfig-checker:
npm install --save-dev editorconfig-checker
npx ec src/
Add the check to CI:
{
"scripts": {
"lint:editorconfig": "editorconfig-checker"
}
}
Configure exclusions in .ecrc:
{
"Exclude": [
"dist",
"node_modules",
".git",
"*.min.js",
"*.min.css"
],
"ExcludeRegex": "vendor/.*"
}

EditorConfig vs Prettier vs ESLint: Comparison
| Tool |
Controls |
Application |
Priority |
| EditorConfig |
Indentation, line endings, encoding |
On file open in IDE |
Basic (editor) |
| Prettier |
Code formatting (braces, semicolons, line breaks) |
On save |
Formatter |
| ESLint |
Code quality and style (rules, best practices) |
On lint or save |
Linter (rules) |
EditorConfig is simpler than Prettier and ESLint: one file, no dependencies, 5x faster to set up. However, EditorConfig does not format code — for that, you need Prettier. We recommend using EditorConfig as a foundation and Prettier for formatting.
Common Pitfalls When Self-Setting
| Mistake |
Consequence |
Solution |
Missing root = true |
EditorConfig may apply rules from parent directories, breaking structure |
Always set root = true in root config |
| Forgetting Makefile |
Makefile requires tabs; build will fail |
Add rule for Makefile: [Makefile] indent_style = tab |
| Mismatch with Prettier |
Conflicts between indent_size in EditorConfig and tabWidth in Prettier |
Align values (e.g., both 2 or 4) |
| Not excluding binary files |
EditorConfig may add final newline to images, corrupting them |
Exclude binary extensions in config |
We account for all these nuances and guarantee a unified standard. Order the setup now — it will save your team up to 2 hours per week on code reviews, a saving of 40% on review time. Get a consultation on your current configuration.

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.

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.
