Thread Header

In this example we will demonstrate how to make a custom ThreadHeader component utilizing the props that are passed to an open Thread.

Create the Component#

The default ThreadHeader shows the number of replies alongside a button to close the thread. In our example we will use the Avatar component to render pictures of the current participants in the thread. We will also change the look of the button and show the number of replies. All of this data and more can be easily pulled from the thread prop, which represents the parent message. The last thing we will utilize is the closeThread function, which is also passed to Thread as a prop.

export const CustomThreadHeader = ({ closeThread, thread }) => {  const replyCount = thread.reply_count;  const threadParticipants = thread.thread_participants;
  return (    <div className='wrapper'>      <div className='participants-wrapper'>        {threadParticipants.map((participant) => (          <div className='participant'>            <Avatar image={participant.image} name={participant.name} />          </div>        ))}        <div className='reply-count'>{replyCount} Replies</div>      </div>      <div onClick={(event) => closeThread(event)} className='close-button'>        <div className='left'>          <div className='right'></div>        </div>      </div>    </div>  );};
.wrapper {  display: flex;  justify-content: space-between;  align-items: center;  width: 100%;  padding: var(--sm-p);  background: var(--white);  box-shadow: 0 7px 9px 0 var(--border), 0 1px 0 0 var(--border);}
.participants-wrapper {  display: flex;  align-items: center;}
.participant:first-child {  margin: 0;}
.participant {  margin-left: calc(var(--md-m) * -1);  border-radius: var(--border-radius-round);  border: 2px solid var(--white);  padding-right: 0;}
.reply-count {  margin-left: var(--sm-m);  font-weight: var(--font-weight-semi-bold);}
.close-button {  width: 24px;  height: 24px;}
.left {  height: 24px;  width: 3px;  border-radius: var(--border-radius-sm);  margin-left: 12px;  background-color: var(--primary-color);  transform: rotate(45deg);  z-index: 1;}
.right {  height: 24px;  width: 3px;  border-radius: var(--border-radius-sm);  background-color: var(--primary-color);  transform: rotate(90deg);  z-index: 2;}

From here all we need to do is override the default component in Channel at the App.tsx level:

<Channel ThreadHeader={CustomThreadHeader}>{/* children of Channel component */}</Channel>

The Result#

Custom Thread Header UI Component for Chat
