How to create a module loader without causing dependency issues?

Help and Feedback Scripting Support
#1

I have a simple library ModuleScript that loads all the modules.

local Library = {}

local modules = game.ReplicatedStorage.Modules

local function Browse(module)
	print(module)
	if module.ClassName == "ModuleScript" then
		Library[module.Name] = require(module)
	end
end

for _, module in ipairs(modules:GetChildren()) do
	print(modules:GetChildren())
	Browse(module)
end

return Library

Scripts can require the Library module to access all the modules. However a problem arises when a module needs to interact with another module via the Library which results in a recursive loop

Any ideas for solutions?

Solution #1

  • Doesn’t wait for the ModuleScripts to load
  • Doesn’t need to be updated for every module added or removed
  • Returns whatever the module indexed returns when required
  • Doesn’t auto-fill at first
local Meta = {
    __index = function(self, Key)
        local Module = script:FindFirstChild(Key)
        if not Module  then return end
        return require(Module)
    end
}

return setmetatable({}, Meta)

---- Usage
Library["FooModule"]

Solution #2

  • Modules will always be loaded when requiring the library
  • Must update for every module added or removed
  • Must require the modules you index
  • Auto-fills
return {
    FooModule = script:WaitForChild("FooModule"),
    BarModule = script:WaitForChild("BarModule"),
    ...
}

--- Usage
require(Library["FooModule"])

I hope this helps
