Definition

Configuration values injected into a process at runtime, used to store secrets and environment-specific settings.

قيم إعداد تُحقن في عملية في وقت التشغيل، تُستخدم لتخزين الأسرار والإعدادات الخاصة بالبيئة.

Why It Matters

FIREBASE_PROJECT_ID, ADMIN_EMAIL, and GLOSSARY_SEED_TOKEN are all environment variables in 404Fault. They must NEVER be committed to git — .env.local is gitignored for this reason.

FIREBASE_PROJECT_ID وADMIN_EMAIL وGLOSSARY_SEED_TOKEN كلها متغيرات بيئة في 404Fault. يجب ألا تُودَع في git أبدًا — .env.local مُدرج في .gitignore لهذا السبب.

Full Definition

Environment variables store configuration that changes between environments (development, staging, production) and secrets that must not be in source code. In Next.js: `.env.local` for local secrets (gitignored), `NEXT_PUBLIC_` prefix exposes to browser, server-only vars remain private. In Vercel, env vars are set in the dashboard and injected at build/runtime. 404Fault uses FIREBASE_PROJECT_ID, ADMIN_EMAIL, and GOOGLE_APPLICATION_CREDENTIALS_JSON via WIF.
متغيرات البيئة تخزّن الإعدادات التي تتغير بين البيئات والأسرار التي يجب ألا تكون في الكود المصدري. في Next.js: `.env.local` للأسرار المحلية (مُدرجة في .gitignore)، بادئة `NEXT_PUBLIC_` تُظهر للمتصفح، المتغيرات الخاصة بالخادم تظل خاصة.

Example Usage

“// .env.local (gitignored) FIREBASE_PROJECT_ID=my-project ADMIN_EMAIL=admin@myapp.com // In code: const projectId = process.env.FIREBASE_PROJECT_ID!;”

“// .env.local (مُدرج في .gitignore) FIREBASE_PROJECT_ID=my-project ADMIN_EMAIL=admin@myapp.com // في الكود: const projectId = process.env.FIREBASE_PROJECT_ID!;”

Avoid these mistakes when using Environment Variables:

1

Committing .env or .env.local — immediately rotate any leaked secrets

2

Accessing NEXT_PUBLIC_ vars server-side and assuming they're secret — they're exposed to the browser
