Follow Anchors

Description of the Feature

In live streaming scenarios, the Follow the host feature is an important interaction method. It allows viewers to choose to follow specific hosts, thus establishing long-term interaction and follow relationships on the live streaming platform. The TUILiveKit has implemented the Follow the host feature through Chat.
Follow feature allows users to choose other users they are interested in so that they can get the latest updates, posts, or event information promptly. You can provide personalized content recommendations based on the user's Follow list.
Fans feature refers to the status of a user being followed by others. When User A follows User B, A becomes a Fan of B.
Through the Follow and Fans features, social applications and websites can create an active and interconnected user network, promoting the dissemination of information and the building of communities.

Use Instructions

Note:
TUILiveKit's Follow the host feature relies on the Chat Follow & Fan APIs, so you need to activate the related Package bundles for Chat. For details, please refer to the Follow&Fan documentation.
