Missing Variables

What it detects

Keys that are defined in .env.example but absent from .env. These are variables your application expects but that have not been configured.

Danger

Missing variables are reported as errors because they are likely to cause runtime failures.

Example

Given .env.example:

APP_NAME=myapp
API_KEY=
REDIS_URL=

And .env:

APP_NAME=myapp

envaudit reports:

Missing variables (in .env.example but not in .env)
  ✗ API_KEY
  ✗ REDIS_URL

Why it matters

A missing variable typically means your app will either:

• Crash on startup when it tries to read the variable
• Silently use a fallback that behaves differently from production
• Fail at runtime when a code path that uses the variable is reached

Fix

Add the missing keys to your .env file, or run envaudit sync to add them automatically with empty values.
