bun-ffi-native-binding

You build high-performance native bindings for JavaScript by leveraging Bun's FFI with Zig or C to expose native APIs with minimal overhead. This approach targets compute-heavy paths and system libraries integration.

Zero-copy data transfer in Bun FFI is handled using typed arrays and buffers. This technique passes data between native C or Zig modules and JavaScript without duplicating memory.

Bun FFI supports safe error propagation and explicit memory ownership handling. These mechanisms ensure reliable execution when bridging low-level C or Zig functionality into JavaScript.

You can use Zig bindgen to create ABI-conscious native modules for Bun. This allows seamless integration with system libraries and data-processing pipelines requiring native performance.

Use cases for integrating system libraries with JavaScript via native bindings include high-performance computation, data-processing pipelines, and bridging low-level functionality to improve compute-intensive workloads.

To compile and verify Zig or C bindings for a Bun FFI project, run the provided build script. This compiles the native bindings and verifies a test invocation using Bun FFI.
