# Exports

### 'getEnv(key, defaultValue?)'
Loads an environment variable by key.  If no default is provided and the variable is missing, throws at startup rather than failing later on.
```javascript
const { getEnv } = require('@nexusai/shared');
const PORT = getEnv('PORT', '3002');         // optional — falls back to 3002
const DB   = getEnv('SQLITE_PATH');          // required — throws if missing
```
