Definition

A single code repository containing multiple related projects or packages, sharing code and tooling.

مستودع كود واحد يحتوي على مشاريع أو حزم متعددة مترابطة، يتشارك الكود والأدوات.

Why It Matters

If 404Fault expands to include a mobile app (React Native) alongside the Next.js web app, a monorepo would let them share types, API clients, and utility functions.

إذا توسعت 404Fault لتشمل تطبيقًا للهاتف المحمول (React Native) إلى جانب تطبيق Next.js للويب، سيتيح monorepo مشاركة الأنواع وعملاء API والدوال المساعدة.

Full Definition

A monorepo stores multiple projects in one Git repository. They share dependencies, CI/CD pipelines, and tooling. Turborepo and Nx are popular monorepo build tools for JavaScript. Benefits: easy code sharing between projects, unified versioning, single PR touching multiple packages. Tradeoffs: larger repo, longer clone times, need for workspace tooling. Common in large companies with frontend/backend sharing types.
Monorepo يخزّن مشاريع متعددة في مستودع Git واحد. تتشارك التبعيات وخطوط أنابيب CI/CD والأدوات. Turborepo وNx أدوات بناء monorepo شائعة لـJavaScript. المزايا: مشاركة سهلة للكود بين المشاريع، إصدار موحّد.

Example Usage

apps/web (Next.js)، apps/mobile (Expo)، packages/types (TypeScript مشترك)، packages/ui (مكونات مشتركة) — كل ذلك في مستودع واحد
