Function envBoolean

envBoolean(options?: EnvBooleanOptions): ExtendedBoolean
Create a boolean schema tuned for environment variables.

The base schema boolean().coerce() intentionally accepts only "true"/"false". Environment variables often use shell-style toggles such as 1, 0, yes, no, on, and off, so this helper normalizes those values before boolean validation runs.
Parameters
- options: EnvBooleanOptions = {}
  Matching behavior and accepted true/false strings.
Returns ExtendedBoolean
A boolean schema builder with env-style string preprocessing.
Example
```
const config = parseEnv({
    debug: env('DEBUG', envBoolean().default(false)),
});
```
