Retrieve Conversations

Conversations provide the last messages for every one-on-one and group conversation the logged-in user is a part of. This makes it easy for you to build a Recent Chat list.

Retrieve List of Conversations​

In other words, as a logged-in user, how do I retrieve the latest conversations that I've been a part of?

To fetch the list of conversations, you can use the ConversationsRequest class. To use this class i.e. to create an object of the ConversationsRequest class, you need to use the ConversationsRequestBuilder class. The ConversationsRequestBuilder class allows you to set the parameters based on which the conversations are to be fetched.

The ConversationsRequestBuilder class allows you to set the below parameters:

Set Limit​

This method sets the limit i.e. the number of conversations that should be fetched in a single iteration.

let limit = 30;
let conversationRequest = new CometChat.ConversationsRequestBuilder()
  .setLimit(limit)
  .build();

Set Conversation Type​

This method can be used to fetch user or group conversations specifically. The conversationType variable can hold one of the below two values:

  • user - Only fetches user conversation.
  • group - Only fetches group conversations.

If none is set, the list of conversations will include both user and group conversations.

let limit = 30;
let conversationType = "group";
let conversationRequest = new CometChat.ConversationsRequestBuilder()
  .setLimit(limit)
  .setConversationType(conversationType)
  .build();

With User and Group Tags​

This method can be used to fetch the user/group tags in the Conversation Object. By default the value is false.

let limit = 30;
let conversationRequest = new CometChat.ConversationsRequestBuilder()
  .setLimit(limit)
  .withUserAndGroupTags(true)
  .build();

Set User Tags​

This method fetches user conversations that have the specified tags.

let limit = 30;
let userTags = ["tag1"];
let conversationRequest = new CometChat.ConversationsRequestBuilder()
  .setLimit(limit)
  .setUserTags(userTags)
  .build();

Set Group Tags​

This method fetches group conversations that have the specified tags.

let limit = 30;
let groupTags = ["tag1"];
let conversationRequest = new CometChat.ConversationsRequestBuilder()
  .setLimit(limit)
  .setGroupTags(groupTags)
  .build();

With Tags​

This method makes sure that the tags associated with the conversations are returned along with the other details of the conversations. The default value for this parameter is false

let limit = 30;
let conversationRequest = new CometChat.ConversationsRequestBuilder()
  .setLimit(limit)
  .withTags(true)
  .build();

Set Tags​

This method helps you fetch the conversations based on the specified tags.

let limit = 30;
let tags = ["archivedChat"];
let conversationRequest = new CometChat.ConversationsRequestBuilder()
  .setLimit(limit)
  .setTags(tags)
  .build();

Include Blocked Users​

This method helps you fetch the conversations of users whom the logged-in user has blocked.

let limit = 30;
let conversationRequest = new CometChat.ConversationsRequestBuilder()
  .setLimit(limit)
  .setIncludeBlockedUsers(true)
  .build();

With Blocked Info​

This method can be used to fetch the blocked information of the blocked user in the ConversationWith object.

let limit = 30;
let conversationRequest = new CometChat.ConversationsRequestBuilder()
  .setLimit(limit)
  .setWithBlockedInfo(true)
  .build();

Finally, once all the parameters are set to the builder class, you need to call the build() method to get the object of the ConversationsRequest class.

Once you have the object of the ConversationsRequest class, you need to call the fetchNext() method. Calling this method will return a list of Conversation objects containing X number of users depending on the limit set.

A Maximum of only 50 Conversations can be fetched at once.

let limit = 30;
let conversationsRequest = new CometChat.ConversationsRequestBuilder()
  .setLimit(limit)
  .build();

conversationsRequest.fetchNext().then(
  (conversationList) => {
    console.log("Conversations list received:", conversationList);
  },
  (error) => {
    console.log("Conversations list fetching failed with error:", error);
  }
);

The Conversation Object consists of the following fields:

FieldInformation
conversationIdID of the conversation.
conversationTypeType of conversation. (user/group)
lastMessageLast message the conversation.
conversationWithUser or Group object containing the details of the user or group.
unreadMessageCountUnread message count for the conversation.

Tag Conversation​

In other words, as a logged-in user, how do I tag a conversation?

To tag a specific conversation, you can use the tagConversation() method. The tagConversation() method accepts three parameters.

  1. conversationWith: UID/GUID of the user/group whose conversation you want to fetch.

  2. conversationType: The conversationType variable can hold one of the below two values:

    1. user - Only fetches user conversation.
    2. group - Only fetches group conversations.

  3. tags: The tags variable will be a list of tags you want to add to a conversation.

let tags = ["archivedChat"];

CometChat.tagConversation("conversationWith", "conversationType", tags).then(
  (conversation) => {
    console.log("conversation", conversation);
  },
  (error) => {
    console.log("error while fetching a conversation", error);
  }
);
info

The tags for conversations are one-way. This means that if user A tags a conversation with user B, that tag will be applied to that conversation only for user A.

Retrieve Single Conversation​

In other words, as a logged-in user, how do I retrieve a specific conversation?

To fetch a specific conversation, you can use the getConversation method. The getConversation method accepts two parameters.

  1. conversationWith: UID/GUID of the user/group whose conversation you want to fetch.
  2. conversationType: The conversationType variable can hold one of the below two values:
    1. user - Only fetches user conversation.
    2. group - Only fetches group conversations.
CometChat.getConversation("conversationWith", "conversationType").then(
  (conversation) => {
    console.log("conversation", conversation);
  },
  (error) => {
    console.log("error while fetching a conversation", error);
  }
);

Convert Messages to Conversations​

As per our receive messages guide, for real-time messages, you will always receive Message objects and not Conversation objects. Thus, you will need a mechanism to convert the Message object to the Conversation object. You can use the getConversationFromMessage(BaseMessage message) of the CometChatHelper class.

CometChat.CometChatHelper.getConversationFromMessage(message).then(
  (conversation) => {
    console.log("Conversation Object", conversation);
  }, (error) => {
    console.log("Error while converting message object", error);
  }
);
info

While converting the Message object to the Conversation object, the unreadMessageCount & tags will not be available in the Conversation object. The unread message count needs to be managed in your client-side code.
