Overview

Koffi is a fast and easy-to-use C FFI module for Node.js, featuring:

  • Low-overhead and fast performance (see benchmarks)
  • Support for primitive and aggregate data types (structs and fixed-size arrays), both by reference (pointer) and by value
  • Javascript functions can be used as C callbacks (since 1.2.0)
  • Well-tested code base for popular OS/architecture combinations

The following combinations of OS and architectures are officially supported and tested at the moment:

Footnotes

  1. The following call conventions are supported: cdecl, stdcall, MS fastcall, thiscall.

  2. The prebuilt binary uses the hard float ABI and expects a VFP coprocessor. Build from source to use Koffi with a different ABI (softfp, soft).

  3. The prebuilt binary uses the LP64D (double-precision float) ABI. The LP64 ABI is supported in theory if you build Koffi from source but this is untested. The LP64F ABI is not supported.
