Message Feed

Within our feed element, we'll generate a feed of messages. Note that we'll replace the pre tags in the next section.

host: {
  "id": 0,
  "host": true,
  "avatar": 48,
  "name": "Jane",
  "timestamp": "Yesterday @ 2:30pm",
  "message": "Harum minima ratione nobis at ratione aliquam assumenda et. Asperiores facere amet aliquam reprehenderit molestias itaque ducimus itaque. Est ea cumque porro omnis.",
  "color": "variant-soft-primary"
}
guest: {
  "id": 1,
  "host": false,
  "avatar": 14,
  "name": "Michael",
  "timestamp": "Yesterday @ 2:45pm",
  "message": "Harum minima ratione nobis at ratione aliquam assumenda et. Asperiores facere amet aliquam reprehenderit molestias itaque ducimus itaque. Est ea cumque porro omnis.",
  "color": "variant-soft-primary"
}

Message Bubbles

By mixing Skeleton features with Tailwind styling, we can provided message bubble interfaces for each type of feed post.

Prompt

We can utilize a Skeleton Input Group to create a custom text prompt.


Scroll to Bottom

Chat windows typically remain fixed at the bottom of the scrollable pane. This can be triggered on page load and when a new message is added.

Use bind:this to bind your scrollable feed element.

typescript
let elemChat: HTMLElement;
html
<div bind:this={elemChat} class="overflow-y-auto">(chat)</div>

Then use Javascript's scrollTo method to scroll the binded element to the bottom on demand. You may also set smooth scrolling via behavior: 'smooth'.

typescript
function scrollChatBottom(behavior?: ScrollBehavior): void {
	elemChat.scrollTo({ top: elemChat.scrollHeight, behavior });
}

Add a Message

Below we'll cover how to append the message feed with a new message from the host user.

Per our above examples, we'll use the same messageFeed data structure.

typescript
let messageFeed = [ /* ...*/ ];

Then bind to the textarea for your prompt in order to capture any message typed by the user.

typescript
let currentMessage = '';
html
<textarea
	bind:value={currentMessage} name="prompt" id="prompt"
	placeholder="Write a message..."
/>

Here's an example of how we might append a new message to the messageFeed array.

typescript
function addMessage(): void {
	const newMessage = {
		id: messageFeed.length,
		host: true,
		avatar: 48,
		name: 'Jane',
		timestamp: new date(),
		message: currentMessage,
		color: 'variant-soft-primary'
	};
	// Append the new message to the message feed
	messageFeed = [...messageFeed, newMessage];
	// Clear the textarea message
	currentMessage = '';
	// Smoothly scroll to the bottom of the feed
	setTimeout(() => { scrollChatBottom('smooth'); }, 0);
}

This can be triggered when the prompt's SEND button is clicked.

html
<button ... on:click={addMessage}>Send</button>
