Manage your Lua modules with npm
Download and install Node.js. Then you have npm
In the root of your project, npm install lua-loader
In the main lua file in your project:
require("node_modules.lua-loader.init")Now require() knows all the new tricks.
Install the lua npm package you want to use in your project, eg. npm install lua-events.
This will install the package as expected in ./node_modules/lua-events.
You can now just:
local EventEmitter = require("lua-events").EventEmitterAnd then just use the module for what it's useful for, eg:
local myObj = EventEmitter:new({text = "Hello, world!"})
function myObj:talk ()
self:emit("spoken", self.text)
end
myObj:on("spoken", function (text)
print("myObj said", text)
end)
myObj:talk()Suppose the following directory structue:
project-root
├── init.lua
├─┬ lib
│ └── foo.lua
└─┬ tests
├── init.lua
└── test-1.lua
- From
init.luayou can loadlib/foo.luawith:
require("./lib/foo")- From
tests/init.luayou can loadtests/test-1.luawith:
require("./test-1")- From
tests/init.luayou can loadlib/foo.luawith:
require("../lib/foo")- Doesn't read the
package.json. So won't respect themainentry in there. Tries to load./init.luaor else./<package name>.luaand that's it.
