[colmtuite]

Feature request

Summary

Avatar component for handling the initials API and image fallback.

Examples in other libraries

https://www.radix-ui.com/primitives/docs/components/avatar

[mnajdova]

Here is the proposed API for the component:

Avatar.Root

• render
• className

Avatar.Image

• src
• alt
• onLoadingStatusChange
• render
• className

Avatar.Fallback

• render
• className
• delay (similar to Radix UI’s delayMs)

---

These are some examples usages:

// Image avatar
<Avatar.Root>
  <Avatar.Image src="" alt="" />
<Avatar.Root>

// Image avatar with fallback
<Avatar.Root>
  <Avatar.Image src="" alt="" />
  <Avatar.Fallback delay={600}>MN</Avatar.Fallback>
<Avatar.Root>

// Initials avatar 
<Avatar.Root>
  MN
<Avatar.Root>
