mfeineis / ElmFxAndCmdsDiscussion.txt

Created March 16, 2018 20:00

A copy of the discussion that lead to the `ElmFxAndCmds.elm` snippet

	Hey, I was just thinking about the `Cmd` being returned from the `init` and `update` functions. I’ve never really liked that, so I was just wondering if anybody else has toyed with the idea to instead return a `List Command` or similar where you’d define your `Command`s just like you define your `Msg`s and then only at the last moment convert them to `Cmd`s?

	Luke is doing something like that, or experimenting with it

	@norpan I have an `AppCmd msg` which only gets converted to `Cmd`s as late as possible. It implements the same API as Cmd, `AppCmd.batch, AppCmd.none etc.` but it allows me to have a lot more control when testing for instance. (edited)
	norpan [1:25 PM]
	exactly, that’s my thinking too
	opsb [1:26 PM]
	It also makes it easier to have commands like `AppCmd.logout`
