Lightning Locker in Communities

Lightning Locker is a powerful security architecture for Lightning components that enhances security by isolating Lightning components in their own namespace. Lightning Locker improves the supportability of your code by allowing access only to supported APIs and eliminating access to non-published framework internals.

Lightning Locker in Communities

Lightning Locker is enabled by default for all new Lightning communities. However, depending on your community’s CSP level, you can choose to turn off Lightning Locker for all components in Experience Builder.

Turning off Lightning Locker can potentially cause security flaws in your community and prevent some components from rendering at runtime.

Warning

To learn more about disabling Lightning Locker and some design considerations to think about, see “CSP and Lightning Locker in Lightning Communities” in Salesforce Help.

You can also disable Lightning Locker for an individual Aura component by setting the component’s API version 39.0 or earlier. However, for consistency and ease of debugging, we recommend that you set the same API version for all components in your app, when possible.
