ffilibs

Pre-compiled static builds of popular open source libraries for Node.js and Bun

🎯 Project Goal

ffilibs provides pre-compiled static versions of popular open source libraries, packaged for easy distribution via npm. This eliminates the need to compile native dependencies from source, making it faster and easier to use powerful libraries like libgit2, libssh2, and others in your JavaScript/TypeScript projects.

Why ffilibs?

• ⚡ Fast Installation: No more waiting for native compilation
• 🔧 Zero Dependencies: Static builds with no external library requirements
• 🌍 Cross-Platform: Support for macOS, Windows, and Linux on both x64 and ARM architectures
• 📦 npm Ready: Simple npm install - no build tools required
• 🦀 Bun Optimized: Works seamlessly with Bun's FFI capabilities

🚀 Quick Start

Installation

npm install @ffilibs/libgit2

Usage with Bun

Bun makes it incredibly easy to call into these native libraries:

import { dlopen, ptr, CString } from 'bun:ffi';
import path from 'path';

// Load the library
const lib = dlopen(path.join(process.cwd(), 'node_modules/@ffilibs/libgit2/prebuilds/linux/arm/lib/libgit2.a'), {
  git_libgit2_init: {
    args: [],
    returns: 'int',
  },
  git_libgit2_shutdown: {
    args: [],
    returns: 'int',
  },
  // Add more functions as needed
});

// Initialize libgit2
lib.symbols.git_libgit2_init();

// Your code here...

// Cleanup
lib.symbols.git_libgit2_shutdown();

🏗️ Supported Platforms

🛠️ Build Process

Each library is built with optimized settings:

• Static linking: No external dependencies
• Release mode: Optimized for performance
• Cross-platform: Built on GitHub Actions for all supported platforms
• Consistent configuration: SSH support enabled where applicable

Local Building

To build a library locally:

cd packages/libgit2
./build.sh

The build script will:

1. Download the source code
2. Configure with appropriate flags
3. Compile with all CPU cores
4. Package into release.tar.gz

🤝 Background

This project is inspired by a tweet from @thdxr:

"there needs to be a project that provides static builds of common libraries (libgit2, treesitter, yoga, etc) for x64 + ARM + mac/windows/linux and publishes them to npm

bun makes it stupid easy to call into these, it's just the packaging that is annoying"
