For Use In
Lightning Experience, Experience Builder Sites
The forceChatter:publisher component is a standalone publisher component you can place on a record page. It works together with the forceChatter:feed component available in the Lightning App Builder to provide a complete Chatter experience. The advantage of having separate components for publisher and feed is the flexibility it gives you in arranging page components. The connection between publisher and feed is automatic and requires no additional coding.
The forceChatter:publisher component includes the context attribute, which determines what type of feed is shown. Use RECORD for a record feed, and GLOBAL for all other feed types.
This component is supported for Lightning Experience and Experience Builder sites based on the Customer Service, Customer Account Portal, Partner Central, and Build Your Own templates.
