Dependencies
The dependencies differ slightly based on the environment you use, and the requirements you have:
- luasocket to establish TCP connections to the MQTT broker. This is a listed dependency in the luamqtt rockspec, so it will automatically be installed if you use LuaRocks to install luamqtt. To install it manually:
luarocks install luasocket
* [optional dependency] copas module for asynchoneous IO. Copas is an advanced co-routine
scheduler with far more features than the included ioloop. For anything more than a few devices, or for devices which
require network IO beyond mqtt alone, Copas is the better alternative. Copas is also pure-Lua, but has parallel network
IO (as opposed to sequential network IO in ioloop), and has features like; threads, timers, locks, semaphores, and
non-blocking clients for http(s), (s)ftp, and smtp.
luarocks install copas
* [optional dependency] luasec module for SSL/TLS based connections. This is optional and may be skipped if you don't need secure network connections (e.g. broker is located in your local network). It's not listed in package dependencies, please install it manually like this:
luarocks install luasec
* [optional dependency] LuaBitOp library to perform bitwise operations, which is required only on Lua 5.1. It's not listed in package dependencies, please install it manually like this:
luarocks install luabitop
* [optional dependency] LuaLogging to enable logging by the MQTT client. This is optional but highly recommended for long running clients. This is a great debugging aid when developing your clients. Also when using OpenResty as your runtime, you'll definitely want to use this, see openresty.lua for an example. It's not listed in package dependencies, please install it manually like this:
luarocks install lualogging
