xStructBinary serialization for TypeScript

Define a schema once, then serialize and deserialize Buffers with full type safety.

🧩

Declarative schemas

Describe a layout with a plain object and concise field strings such as UInt32LE, FloatBE, or utf8(32).

🛡️

Parameterize a struct with an interface and let TypeScript check the objects you encode and decode.

🔢

8, 16, and 32-bit integers, 64-bit BigInt, and single and double floats, each with explicit endianness.

🧵

Length-prefixed, fixed-size, or null-terminated strings in UTF-8 and ASCII, plus string arrays.

⚡

Pack sub-byte fields into a shared integer container for compact protocols and registers.

📦

A small library with no runtime dependencies that runs anywhere a Buffer is available.
