Global Lightning Components are those you can use directly in your own component markup. This should be the sum of all access="global"
Aura Components and all LWC Components, which I believe are always "global," as far as I've ever been able to tell.
App Builder Components are those that are configured to appear in Lightning App Builder. These components are Aura Components that additionally define use an interface that makes it eligible for App Builder use (e.g. flexipage:availableForAllPageTypes
), as well as LWC where isExposed
is set to true, and has at least one target (e.g. lightning__RecordPage
) that relates to App Builder.
Community Builder Components are those that are configured to appear in a Digital Experience. This includes Aura components that include interfaces such as forceCommunity:availableForAllPageTypes
, and LWC Components that have isExposed
set to true, and at least one target that allows it to be used as such (e.g. lightningCommunity__Page
).
In your example summary, note that there are not a total of 16 components in the package; there are only seven, all of which can be added in the App Builder, and only two in the Digital Experience Builder. The "global value" will be at least as big as either of the other two numbers. The summary tells you more information about what kind of functionality the package provides.
