What it does

Checks for valid uses of Roact.createElement. Verifies that class name given is valid and that the properties passed for it are valid for that class.

Why this is bad

This is guaranteed to fail once it is rendered. Furthermore, the createElement itself will not error--only once its mounted will it error.


Roact.createElement("Frame", {
    ThisPropertyDoesntExist = true,

    [Roact.Event.ThisEventDoesntExist] = function() end,

Roact.createElement("BadClass", {})


This lint is naive and makes several assumptions about the way you write your code. The assumptions are based on idiomatic Roact.

  1. It assumes you are either calling Roact.createElement directly or creating a local variable that's assigned to Roact.createElement.
  2. It assumes if you are using a local variable, you're not reassigning it.
  3. It assumes Roact is defined. undefined_variable will still lint, however.

This lint does not verify if the value you are giving is correct, so Text = will be treated as correct. This lint, right now, only checks property and class names.

This lint is only active if you are using the Roblox standard library.
