Extensions

An extension simply adds functionality or transformation to a provider during runtime. Extensions are useful for collectively modifying providers externally within the Glue Intialization pipeline.

Glue provides two modifiable extensions:

  • beforeCreate: This extension is run before the provider is created.
  • beforeStart: This extension is run before the provider is started.

How do you specifiy an extension?

Glue.Extensions({
    beforeCreate = function(provider)

    end,
    beforeStart = function(provider)

    end
})

Logger - Extenstion​

A built-in logger.

local Services = {}
Glue.Extensions({
    beforeCreate = function(provider)
        provider._log = function(msg)
            print(`[{provider.Name}] {msg}`)
        end
    end
})
function Provider:onStart()
    self._log("Hello world.")
end
