Validate Aura Component Public API (secure-component)

This rule validates that only public, supported framework API functions and properties are used.
When Lightning Locker is enabled, the framework prevents the use of unsupported API objects or calls. That means your Aura components code is allowed to use:
  • Features built into JavaScript (“intrinsic” features)
  • Published, supported features built into the Aura Components programming model.
  • Published, supported features built into Lightning Locker SecureObject objects

Prior to Lightning Locker, when you created or obtained a reference to a component, you could call any function and access any property available on that component, even if it wasn’t public. When Lightning Locker is enabled, components are “wrapped” by a new SecureComponent object, which controls access to the component and its functions and properties. SecureComponent restricts you to using only published, supported component API.
