Conversations

Once authenticated, users can send or receive messages, which are tied to a Conversation.

1. Create StringeeChat Object

You will use StringeeChat object to perform actions related to chat.

  // global
  var stringeeChat;

  // init
  stringeeChat = new StringeeChat(stringeeClient);

2. Create a conversation

A Conversation is created by calling stringeeChat.createConversation(userIds, options, callback):

    stringeeChat.createConversation(userIds, options, (status, code, message, conv) => {
      console.log('status:' + status + ' code:' + code + ' message:' + message + ' conv:' + JSON.stringify(conv));
    });

In which:

2.1. Chat 1-1

To create a Chat 1-1 Conversation, you must pass userIds with only one user id, isGroup = false, for example:

    var userIds = ["user1"];
    var options = {
      name: "Your conversation name",
      isDistinct: false/true,
      isGroup: false
    };

A Chat 1-1 Conversation is a distinct Conversation by default. You can not add participants to a Chat 1-1 Conversation.

Note:

If you pass userIds with more than one user id, the Conversation is created as a Group Chat Conversation.

2.2. Group Chat

To create a Group Chat Conversation, you pass isGroup = true or userIds with more than one user id:

    var userIds = ["user1", "user2", ...];
    var options = {
      name: "Tên conversation",
      isDistinct: false/true,
      isGroup: true
    };

You can add or remove participants to/from a Conversation.

2.3. Distinct Conversations

If a Conversation is created as a distinct Conversation, it's unique on Stringee server. This means, multiple users independently create distinct Conversations with the same set of users, the server will automatically merge the conversations.

Once a Distinct Conversation has been created between User A and User B, any further attempts by either of these users to create a new Distinct Conversation with these participants will get resolved to the existing Conversation.

Conversations are created as non-distinct Conversations by default.

Creating a distinct Conversation by set isDistinct option:

3. Get Conversations

Conversations are stored on Stringee server. You can get conversations as follows:

3.1 Get Last Conversations

To get lastest conversations from Stringee server, you call stringeeClient.getLastConversations(count, isAscending, callback):

  var count = 50;
  var isAscending = false;

  stringeeChat.getLastConversations(count, isAscending, function (status, code, message, convs) {
    console.log('status: ' + status + '  ' + code + message + ' convs:' + JSON.stringify(convs));
  });

In which:

3.2 Get Conversations After

To get a list of conversations which have updated time greater than a datetime from server, you call:

  var datetime = 1569559556088;
  var count = 50;
  var isAscending = false;

  stringeeChat.getConversationsAfter(datetime, count, isAscending, function (status, code, message, convs) {
    console.log(status + code + message + ' convs:' + JSON.stringify(convs));
  });

In which:

3.3 Get Conversations Before

To get a list of conversations which have updated time smaller than datetime from server, you call:

  var datetime = 1569559556088;
  var count = 50;
  var isAscending = false;

  stringeeChat.getConversationsBefore(datetime, count, isAscending, function (status, code, message, convs) {
    console.log(status + code + message + ' convs:' + JSON.stringify(convs));
  });

In which:

4. Participants

Participants in a Conversation. Any participant can add users into a Conversation or leave a Conversation. Only the participant who created the Conversation can remove other participants from the Conversation:

  // Add
  var convId = 'YOUR_CONVERSATION_ID';
  var userIds = ['name3'];
  stringeeChat.addParticipants(convId, userIds, function (status, code, message, added) {
    console.log('status:' + status + ' code:' + code + ' message:' + message + 'added: ' + JSON.stringify(added));
  });

  // Remove
  var convId = 'YOUR_CONVERSATION_ID';
  var userIds = ['name3'];
  stringeeChat.removeParticipants(convId, userIds, function (status, code, message, removed) {
    console.log('status:' + status + ' code:' + code + ' message:' + message + 'removed: ' + JSON.stringify(removed));
  });

When you remove a participant, that participant will receive an event:

    stringeeChat.on('removeParticipantFromServer', function (info) {
        console.log('removeParticipantFromServer ' + JSON.stringify(info));
    });
Note:

To leave a Conversation, you remove yourself from the Conversation.

5. Update Conversation

You can update conversation's info by the following function:

    var convId = 'YOUR-CONVERSATION-ID';
    var params = {
        name: "New Name 1",
        imageUrl: "AVATAR'S URL"
    };

    stringeeChat.updateConversation(convId, params, function (status, code, message) {
        console.log('status:' + status + ' code:' + code + ' message:' + message);
    });

6. Delete Conversation

In case the Conversation is Chat 1-1, you can delete the Conversation by calling:

  var convId = 'YOUR_CONVERSATION_ID';
  stringeeChat.deleteConversation(convId, function (status, code, message) {
    console.log('status:' + status + ' code:' + code + ' message:' + message);
  });

In case the Conversation is Group Chat, you must leave the Conversation before deleting.
