  "DATABASE_URL": "postgresql://localhost:5432/mydb",

Tips

• Variable names should be UPPERCASE with underscores
• Values with spaces are automatically quoted in output
• Mark sensitive values as "Secret" to hide them by default
• Never commit .env files with real secrets to version control

Environment Variables - 技术详情

.env files store configuration as KEY=VALUE pairs. They're loaded at runtime by tools like dotenv. Never commit real secrets to version control—use .env.example templates instead.

命令行替代方案

# Load .env in Node.js\nrequire('dotenv').config()\n\n# Access variables\nprocess.env.DATABASE_URL\n\n# Load in shell\nexport $(cat .env | xargs)
