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

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

export function validateEnumValue(key, value, args) {
    const allowedValues = args;
    if (!Array.isArray(allowedValues)) {
        return `Invalid enum definition for ${key}, expected an array of allowed values`;
    }
    if (!allowedValues.includes(value)) {
        return `${key} must be one of: ${allowedValues.join(', ')}`;
    }
    return true;
