nodish

A lightweight Lua equivalent to Node.js. .

Motivation / Target Audience

This framework might be for you, if you want node.js like API, but:

• You have very limited ressources (memory)
• You need a lua-ev backend
• You are interested in a "Lua-only" (>90%) implementation

Unlike luvit or LuaNode this project does NOT (yet) try to be a complete node.js port. Instead it tries to keep dependecies as minimal as possible to keep size small for embedded systems. To use nodish you need:

Interpreter

• luajit (or Lua + luaffi)

Lua modules

• ljsyscall to interface to the system (sockets,read,write,etc)
• lua-ev as I/O loop framework

C libraries

• Any ljsyscall compatible libc
• libev

To reduce size further, you may be interested in squish.

NOTE: If you have no ressource problems, you should use a more robust and mature implementation like luvit or LuaNode or event better, just use the fantastic Node.js!

Examples

Echo Server

local net = require'nodish.net'
local process = require'nodish.process'

net.createServer(function(client)
	client:pipe(client)
	client:pipe(process.stdout)
  end):listen(12345)

process.loop()    

Echo Client

local net = require'nodish.net'
local process = require'nodish.process'

local client = net.connect(12345)
client:on('connect',function()
	process.stdin:pipe(client)
	client:pipe(process.stdout)
  end)

process.loop()
