#ffi

Calling a C function from Bun via bun:ffi

import { dlopen, FFIType, suffix } from "bun:ffi";

const path = `libsqlite3.${suffix}`;

const { symbols } = dlopen(path, {

bun:ffi's dlopen loads a shared library and JIT-compiles a JS-to-native binding for each symbol, letting Bun call C functions directly with no N-API glue code.
