node-env-resolver-nextjs@7.1.0

Minor Changes

• e71a403: Add support for optional enum arrays with new enumOf() function and optional() wrapper.

  New Features:

  • enumOf() function: A clearer, more explicit alternative to oneOf() specifically designed for enum validation. Supports optional values and default values.
  • optional() wrapper: Enables clean array literal syntax for optional enums. Simply wrap your enum array with optional() to make it optional.

  Usage Examples:

  import { resolve } from 'node-env-resolver';
  import { optional, enumOf } from 'node-env-resolver/validators';
  
  const config = resolve({
    // Required enum (existing syntax still works)
    NODE_ENV: ['development', 'production', 'test'] as const,
  
    // Optional enum - Method 1: optional() wrapper (clean syntax)
    PROTOCOL: optional(['http', 'grpc'] as const),
  
    // Optional enum - Method 2: enumOf() function (explicit)
    LOG_LEVEL: enumOf(['error', 'warn', 'info', 'debug'] as const, { optional: true }),
  
    // Enum with default value
    COMPRESSION: enumOf(['gzip', 'brotli', 'none'] as const, { default: 'gzip' }),
  });
  
  // TypeScript infers correct types:
  // config.NODE_ENV: 'development' | 'production' | 'test'
  // config.PROTOCOL: 'http' | 'grpc' | undefined
  // config.LOG_LEVEL: 'error' | 'warn' | 'info' | 'debug' | undefined
  // config.COMPRESSION: 'gzip' | 'brotli' | 'none'

  Backward Compatibility:

  • All existing code continues to work unchanged
  • oneOf() remains available as an alias for enumOf() for backward compatibility
  • Plain array syntax ['a', 'b'] as const still works for required enums
