Buffer Layout

buffer-layout is a pure JavaScript utility library designed for translating between JavaScript values and Node.js Buffers. It enables developers to define and manipulate binary data structures that closely mimic C structs, offering explicit control over memory layout and endianness. The library provides layout constructors for various data types, including signed and unsigned integers (1 to 6 bytes, with 64-bit integers decoded as standard JavaScript Numbers), floats, doubles, sequences, complex structures, unions, bit fields, NUL-terminated C strings, and raw data blobs. The current version, 1.2.2, was last published in 2021. Given its age and lack of recent updates on its GitHub repository (last commit approximately four years ago), the project appears to be in an abandoned state, with no active development or maintenance. A key differentiator is its detailed control over C-style memory layouts, including the necessity of manually accounting for padding and bit fields.
