Lua Evolved.

Using the Node-Style APIs

The luvit CLI tool can be used as a scripting platform just like node...

This simple web server responds with Hello World, and you can run it with luvit server.lua:

No need for Apache or Nginx - it that good, it just works.

local http = require("http")

http.createServer(function(req, res)
  local body = "Hello world\n"
  res:setHeader("Content-Type", "text/plain")
  res:setHeader("Content-Length", #body)
  res:finish(body)
end):listen(8080, "127.0.0.1")

print("Server running at http://127.0.0.1:8080/")

> luvit server.lua
Server running at http://127.0.0.1:8080/

local weblit = require("weblit")

weblit.app.bind({ host = "127.0.0.1", port = 1337 })

-- Configure weblit server
    .use(weblit.logger)
    .use(weblit.autoHeaders)

-- A custom route that sends back method and part of url.
    .route({ path = "/:name" }, function(req, res)
        res.body = req.method .. " - " .. req.params.name .. "\n"
        res.code = 200
        res.headers["content-type"] = "text/plain"
    end)

-- Start the server
    .start()

Using Third-Party Libraries

Say goodbye to complicated build pipelines. Luvit's lit package system makes dependency management painless and scriptable.

For example, @creationix created coroutine-based libraries like weblit.

Install with lit install creationix/weblit and serve with luvit.

> mkdir myapp && cd myapp
> lit install creationix/weblit
> nano server.lua
> luvit server.lua
