This reference covers the envModel format used by @vibenv/env-manager.

envModel value types

• boolean: true or false
• number: any numeric value
• string: a default value, optionally followed by alternatives separated by |

Example:

{
  "envModel": {
    "LOG_LEVEL": "info|debug|warn|error",
    "PORT": 3000,
    "DEBUG": false
  }
}

Generated .env rules

• Keys are sorted alphabetically.
• When a string has | separators, alternatives are emitted as a # comment above the key.
• Existing .env values are preserved when they match the expected type.
• Type mismatches fall back to the default value and emit a warning.
