README

The examples demonstrate the use of websocketd with lua. There are two examples in the directory both very basic.

1. Greeter.lua simply echos back any input made from the client
2. json_ws.lua echos back any input from the client after converting it into a json string

It is pretty simple to extend these examples into full fledged applications. All you need is an stdin input loop

local input = io.stdin:read()

while input do
-- do anything here

-- update the input
input = io.stdin:read()

end

any thing you print goes out to the websocket client

Libraries and third party modules can be used by the standard require statement in lua.

Running the examples

1. Download

Install websocketd and add it to your PATH.

2. Start a server: greeter

Run websocketd --port=8080 --devconsole lua ./greeter.lua and then go to http://localhost:8080 to interact with it

3. Start a server: json_ws

Run websocketd --port=8080 --devconsole lua ./json_ws.lua and then go to http://localhost:8080 to interact with it

If you are using luajit instead of lua you may run the examples like this (this assumes that you've got luajit in your path)

websocketd --port=8080 --devconsole luajit ./json_ws.lua and then go to http://localhost:8080
