关于GetStream Chat用户频道邀请列表查询及相关功能的技术问询

Hey there! Let's break down how to implement your three key workflow requirements using GetStream Chat, even though some of these aren't explicitly called out in the docs:

1. Fetch a User's Pending Channel Invites #

While the official docs don't highlight this directly, you can leverage the queryChannels endpoint with targeted filters to pull up all channels where the user has a pending invite.

GetStream automatically adds invited users to a channel's members collection with an invited: true flag (until they accept or reject). You can filter for this with a query like:

// Using GetStream JS SDK
const pendingInvites = await client.queryChannels(
  {
    members: { $in: [currentUserId] },
    'members.invited': true
  },
  { last_message_at: -1 } // Sort by most recent invite first
);

This will return all channels where the user is an invited (but not yet accepted/rejected) member—perfect for letting users choose to act immediately or later.

2. Rejected Invites: Allow Users to Re-Accept #

By default, calling rejectInvite removes the user from the channel's members collection, which makes it hard to track rejected invites. Instead, tweak your rejection flow to keep a record:

• When a user rejects an invite, don't call rejectInvite directly. Instead, update the user's member record in the channel with a custom flag:

  await channel.updateMember(currentUserId, {
    custom: { rejected_invite: true },
    invited: false // Mark invite as no longer pending
  });
  

• To let users find rejected channels later, query for channels where their member record has rejected_invite: true:

  const rejectedChannels = await client.queryChannels(
    {
      members: { $in: [currentUserId] },
      'members.custom.rejected_invite': true
    }
  );
  

• When the user wants to re-accept, update the member record again to remove the rejected_invite flag, and call acceptInvite to join the channel properly.

3. Push Notification Preferences for New Invites #

GetStream supports user-level notification customization that you can adapt for invite alerts:

• Add a custom field to the user's profile to track their preference:

  await client.updateUser({
    id: currentUserId,
    custom: { receive_invite_push: true } // Default to enabled
  });
  

• When sending a channel invite, check this user field before triggering a push notification. You can handle this either in your backend (when calling sendInvite) or using GetStream's webhooks to intercept invite events and conditionally send pushes.
• For a more native approach, you can also use GetStream's built-in notification settings to let users mute specific channel types or adjust global notification preferences, then map those settings to invite alerts.

This approach avoids the need for clunky per-invitee custom fields and aligns with GetStream's existing data model.
