Unofficial AWS SDK for Lua, available for LuaJIT and Lua 5.1 and later. The SDK has been used in production, specifically GameLift, but several other services are untested.
For release notes, see the CHANGELOG.
You can use the AWS SDK for Lua in your own project by adding this project as a Defold library dependency. Open your game.project file and in the dependencies field under project add:
https://github.com/britzl/aws-sdk-lua/archive/master.zip
Or point to the ZIP file of a specific release.
The SDK is currently not distributed via LuaRocks. LuaRocks distribution will happen once the SDK is stable and moved out of beta.
Using the AWS SDK for Lua is a simple process requiring only a few steps of configuration:
-- Configure AWS to work with Defold (specifically to use http.request() provided by the Defold engine to make HTTP calls)
local config = require "aws-skd.core.config"
config.use_defold()
-- config.use_corona()
-- config.use_luasocket()
-- Set access key and secret access key (read this from config file or os.env)
local credentials = require "aws-sdk.core.credentials"
credentials.set(access_key, secret_access_key)
-- Initialise the AWS service to use, in this case GameLift
local gamelift = require "aws-sdk.gamelift"
gamelift.init({ region = "eu-central-1" })
-- Make a call to a GameLift endpoint
local input = gamelift.CreateGameSessionInput({
CreatorId = "c6e209af-4ac0-47b4-c752-60f81db6d2d0",
AliasId = "alias-4cfbed10-a54d-4e9f-8bc0-ba7f98a6ef40",
Name = "My session",
MaximumPlayerSessionCount = 10
})
gamelift.CreateGameSessionAsync(input, function(response, error_message)
if not error_message then
print(response.GameSession.GameSessionId)
end
end)
The SDK generates the code for all AWS services, their input and output including input validation. The code generator uses official AWS SDK API definitions from the AWS SDK for Javascript project. The code generator uses a Mustache template and a small Python script to parse the API definitions and outputs one Lua file per AWS service. You can run the generator yourself from a terminal:
python generate.py
The script reads the definition files from apis/ folder and outputs generated code to the aws-sdk/ folder.
