채팅방을 들어오거나 나갈 때, separator를 이용해 표시해 보자.

MessageSeparator 추가하기

 

먼저 MessageList에 임의로 Separator를 추가해 보자.

  <MessageList>
    {getMessageComponent(messages)}
    <MessageSeparator content="Joe has entered the chatroom." />
    <MessageSeparator content="Joe has left the chatroom." />
  </MessageList>

 

다음과 같이 채팅창에 선이 추가 된다.

 

이제 기본 메시지는 모두 빈 메시지로 처리하자.

const defaultMessage = [];
const defaultMessagePatrik = [];
const totalMessages = [defaultMessage, defaultMessagePatrik];

 

getMessageComponent는 type에 따라 Separator를 만들거나 기존 Message를 return하면 된다.

  const getMessageComponent = (totalMessages) => {
    let data = totalMessages[activeID];

    return data.map((item, index) => {
      return item.type === "separator" ? (
        <MessageSeparator key={index} content={item.content} />
      ) : (
        <Message key={index} model={item.model}>
          {item.avatar ? (
            <Avatar src={item.avatar.src} name={item.avatar.name} />
          ) : null}
        </Message>
      );
    });
  };

 

여기서는 방을 변경할 때, 채팅방을 나가는 것으로 가정한다.

같은 방을 클릭할 경우에는 아무 이벤트도 발생하지 않는다.

  const changeRoom = (index) => {
    if(activeID === index) return;
    
    let leftSeparator = {
      type : "separator",
      content : `${loginID} has left the chatroom.`,
    }

    let enterSeparator = {
      type : "separator",
      content : `${loginID} has entered the chatroom.`,
    }

    let temp = [...totalMessages];
    temp[activeID].push(leftSeparator);
    temp[index].push(enterSeparator);

    setMessages(temp);
    setActiveID(index);
  }

  const getConversationComponent = (data) => {
    return data.map((item, index) => {
      return (
        <Conversation
          ...
          onClick={() => changeRoom(index)}
        >
          <Avatar name={item.name} src={item.src} status={item.status} />
        </Conversation>
      );
    });
  };

 

마지막으로 최초 진입 시, 넘겨 받은 loginID로 Separator를 만들면 된다.

  const init = () => {
    setLoginID(location.state.loginID);

    let enterSeparator = {
      type : "separator",
      content : `${location.state.loginID} has entered the chatroom.`,
    }

    let temp = [...totalMessages];
    temp[activeID].push(enterSeparator);

    setMessages(temp);    
  };
