# 06. Channels Read API
|
||||||
|
|
||||||
|
## Человеко-читаемое объяснение
|
||||||
|
Эти 3 функции — это **чтение данных каналов** для UI:
|
||||||
|
|
||||||
|
1. `ListSubscriptionsFeed` — отдает данные для экрана списка каналов:
|
||||||
|
- ваши каналы (личный + созданные вами),
|
||||||
|
- каналы пользователей, на кого вы подписаны,
|
||||||
|
- отдельные каналы, на которые вы подписаны напрямую.
|
||||||
|
|
||||||
|
2. `GetChannelMessages` — отдает полную ленту одного канала (пока без курсоров, загружается сразу целиком),
|
||||||
|
включая версии сообщений, лайки и ответы.
|
||||||
|
|
||||||
|
3. `GetMessageThread` — отдает дерево обсуждения вокруг конкретного сообщения:
|
||||||
|
предки, фокус-сообщение, потомки.
|
||||||
|
|
||||||
|
> На первом этапе мы **не используем курсоры** (`nextCursor`) и загружаем полные списки.
