stream-shift

Returns the next buffer/object in a Node.js stream's readable queue without consuming it. Version 1.0.3 is the latest stable release. The package is minimal and focused, primarily used internally by higher-level stream utilities. It works on Node.js 6+ and is commonly used in modules like `pump`, `through2`, and others that need to peek into a stream's internal buffer. It is not a user-facing tool but a low-level utility for stream manipulation.
