env-sentinel/dist/validation/validate-boolean-value.js

Zero-dependency tool that auto-validates .env files against schema.env, with optional fallback and secure warnings.

export function validateBooleanValue(key, value) {
    const lowerValue = value.toLowerCase();
    return ['true', 'false'].includes(lowerValue) ? true : `Invalid boolean for ${key}, must be 'true' or 'false'`;
}
