How do I stop the message list component in Stream.io chat from growing infinitely?-CodePudding

Im trying to use the Stream chat react components included in the library. I'm having an issue where new messages will continuosly increase the size of the component and cause it to go off screen. I'm trying to have it fill the space of a container div.

I've tried messing around with max-height and looking through the CSS variables in the Stream.io docs but nothing is working.

Glad that you're using Stream for your react chat app. I'm happy to help you, but I'd need a bit more information from your side to do this.

Are you using our built-in MessageList component? If yes, as you can see in the docs it provides auto-scrolling when new messages arrive (combined with many more customization options you can find in the documentation).

If you're manually handling the showing of messages I'd have to ask for the code that you have before being able to identify the issue with it.

Happy to hear from you for more thorough help! :)

Best, Stefan

To prevent the message list component in Stream.io chat from growing infinitely, you can implement pagination or implement a limit to the number of messages displayed in the component. Here's an example of how you can implement a limit:

import React, { useState } from 'react';

const MessageList = ({ messages }) => {
  const [limit, setLimit] = useState(20);
  const messagesToDisplay = messages.slice(0, limit);

  const handleLoadMore = () => {
    setLimit(limit   20);
  };

  return (
    <div>
      {messagesToDisplay.map((message, index) => (
        <Message key={index} message={message} />
      ))}
      {limit < messages.length && (
        <button onClick={handleLoadMore}>Load More</button>
      )}
    </div>
  );
};

export default MessageList

This code implements a limit of 20 messages to be displayed at a time in the MessageList component. The handleLoadMore function allows the user to view more messages, by increasing the limit by 20. The messagesToDisplay variable stores the messages that are displayed in the component based on the limit, and the "Load More" button is displayed only if there are more messages that can be displayed
