@bun-win32/netapi32

Zero-dependency, zero-overhead Win32 NETAPI32 bindings for Bun on Windows.

Overview

@bun-win32/netapi32 exposes the netapi32.dll exports using Bun's FFI. It provides a single class, Netapi32, which lazily binds native symbols on first use. You can optionally preload a subset or all symbols up-front via Preload().

The bindings are strongly typed for a smooth DX in TypeScript.

Features

• Bun-first ergonomics on Windows 10/11.
• Direct FFI to netapi32.dll (users, groups, shares, sessions, servers, workstations, domain joins, WebDAV, DC locator, and more).
• In-source docs in structs/Netapi32.ts with links to Microsoft Docs.
• Lazy binding on first call; optional eager preload (Netapi32.Preload()).
• No wrapper overhead; calls map 1:1 to native APIs.
• Strongly-typed Win32 aliases (see types/Netapi32.ts).

Requirements

• Bun runtime
• Windows 10 or later

Installation

bun add @bun-win32/netapi32

Quick Start

import Netapi32, { NERR_Success } from '@bun-win32/netapi32';

// Optionally bind a subset up-front
Netapi32.Preload(['NetWkstaGetInfo', 'NetApiBufferFree']);

// Query workstation info
const buf = Buffer.alloc(8);
const status = Netapi32.NetWkstaGetInfo(null, 100, buf.ptr);

if (status === NERR_Success) {
  console.log('NetWkstaGetInfo succeeded.');
}

Netapi32.NetApiBufferFree(buf.ptr);

AI agents: see AI.md for the package binding contract and source-navigation guidance. It explains how to use the package without scanning the entire implementation.

Examples

Run the included examples:

bun run example              # Workstation info + user enumeration

Notes

• Either rely on lazy binding or call Netapi32.Preload().
• Windows only. Bun runtime required.
