Api: ✏️ Append LastMessage Field in ChatRoomDetail Response

[psychology50]

작업 이유

• When client requests ChatRoomDetail, the server must include the lastMessage field.
• However, this data doesn't need to be highly reliable compared to unreadMessageCount. Since any user in the chatroom can send message simultaneously, even if the server retrieves an earlier message, the client will replace the lastMessage component with the latest message from the the socket server.

    {
      "id": 0,
      "title": "string",
      "description": "string",
      "backgroundImageUrl": "string",
      "isPrivate": true,
      "isAdmin": true,
      "participantCount": 0,

      "lastMessage": { // Append this field 
        "chatRoomId": 0,
        "chatId": 0,
        "content": "string",
        "contentType": "TEXT",
        "categoryType": "NORMAL",
        "createdAt": "2024-11-11T05:29:12.715Z",
        "senderId": 0
      },
      "unreadMessageCount": 0
    }
  ]
}

• if the server can't find the lastMessage, this field will be null
  • I want to replace {}, but this work is so hard...
• APIs that share this response DTO will also be updated accordingly, but the rule is straightforward.
  • Search Chatroom: The lastMessage field isn't required and is always null
  • Join Chatroom: When the client joins a chatroom, it will enter the chatroom, so this field isn't necessary.
