This project provides a LuaJIT FFI binding to libuv, the async I/O library powering Node.js. It uses Lua coroutines to provide non-blocking I/O with synchronous syntax.

For example, you can build a web server that performs I/O (like reading a file or talking to a database) while generating each response, and it will process multiple requests simultaneously.

local http = require 'uv.http'
local fs = require 'uv.fs'

http.listen('127.0.0.1', 8080, function(request)
  return { status = 200, body = fs.readfile('README.md') }
end)

Or you can perform multiple HTTP requests simultaneously.

local http = require 'uv.http'
local parallel = require 'uv.parallel'

local requests = {
  { url = 'http://www.google.com/' },
  { url = 'http://www.bing.com/' },
  { url = 'http://www.amazon.com/' },
}

local responses = parallel.map(requests, http.request)

Not production ready. Under active development. The API is unstable.

• LuaJIT. Regular Lua won't run it. That said, you probably want LuaJIT anyway.

• Standard build tools.

• libuv and http-parser are bundled and do not need to be installed separately.

git clone https://github.com/pguillory/luajit-libuv.git
cd luajit-libuv
make
make install

Functions are divided into submodules. Each submodule can either be required directly or accessed indirectly through the uv module:

local fs = require 'uv.fs'

local uv = require 'uv'
local fs = uv.fs

• uv.fs - File system
• uv.http - HTTP client and server
• uv.loop - Event loop control
• uv.parallel - Parallel processing
• uv.process - Process management
• uv.system - System utility functions
• uv.timer - Timers
• uv.url - URL parsing and encoding
