Push Preferences on Follow

When following a feed, you can set push_preference to control push notifications for future activities from that feed:

all - Receive push notifications for all activities from the followed feed
none (default) - Don’t receive push notifications for activities from the followed feed

Note: The push_preference parameter controls future notifications from the followed feed, while skip_push controls whether the follow action itself triggers a notification.

Examples: Push Preferences vs Skip Push

Understanding the difference between push_preference and skip_push:

// Scenario 1: Follow a user and receive notifications for their future activities
await timeline.follow("user:alice", {
  push_preference: "all", // You'll get push notifications for Alice's future posts
});

// Scenario 2: Follow a user but don't get notifications for their activities
await timeline.follow("user:bob", {
  push_preference: "none", // You won't get push notifications for Bob's future posts
});

// Scenario 3: Follow a user silently
await timeline.follow("user:charlie", {
  skip_push: true, // Charlie won't get a "you have a new follower" notification
  push_preference: "all", // But you'll still get notifications for Charlie's future posts
});

// Scenario 4: Silent follow with no future notifications
await timeline.follow("user:diana", {
  skip_push: true, // Diana won't know you followed her
  push_preference: "none", // And you won't get notifications for her posts
});
