The Avatar component is a React component that represents a user avatar or profile picture. It displays an image or initials within container.

Avatar provides support for fallback text or elements when the image fails to load, or when the image is not provided.



To use the avatar machine in your project, run the following command in your command line:

npm install @zag-js/avatar @zag-js/react # or yarn add @zag-js/avatar @zag-js/react

This command will install the framework agnostic avatar logic and the reactive utilities for your framework of choice.


To set up the avatar correctly, you'll need to understand its anatomy and how we name its parts.

Each part includes a data-part attribute to help identify them in the DOM.


First, import the avatar package into your project

import * as avatar from "@zag-js/avatar"

The avatar package exports two key functions:

  • machine — The state machine logic for the avatar widget.
  • connect — The function that translates the machine's state to JSX attributes and event handlers.

You'll also need to provide a unique id to the useMachine hook. This is used to ensure that every part has a unique identifier.

Next, import the required hooks and functions for your framework and use the avatar machine in your project 🔥

import * as avatar from "@zag-js/avatar" import { useMachine, normalizeProps } from "@zag-js/react" function Avatar() { const [state, send] = useMachine(avatar.machine({ id: "1" })) const api = avatar.connect(state, send, normalizeProps) return ( <div {...api.getRootProps()}> <span {...api.getFallbackProps()}>PA</span> <img alt="PA" src={src} {...api.getImageProps()} /> </div> ) }

Listening for loading status changes

When the image has loaded or failed to load, the onStatusChange callback is invoked.

const [state, send] = useMachine( avatar.machine({ onStatusChange(details) { // details => { status: "error" | "loaded" } }, }), )

Styling guide

Earlier, we mentioned that each avatar part has a data-part attribute added to them to select and style them in the DOM.

[data-scope="avatar"][data-part="root"] { /* Styles for the root part */ } [data-scope="avatar"][data-part="image"] { /* Styles for the image part */ } [data-scope="avatar"][data-part="fallback"] { /* Styles for the fallback part */ }

Creating Component

Create your avatar component by abstracting the machine into your own component.


import { Avatar } from "./your-avatar" function Demo() { return ( <Avatar src="" name="John Doe" /> ) }


Use the the splitProps utility to separate the machine's props from the component's props.

import * as avatar from "@zag-js/avatar" import { useMachine, normalizeProps } from "@zag-js/react" export interface AvatarProps extends Omit<avatar.Context, "id"> { /** * The src of the avatar image */ src?: string /** * The srcSet of the avatar image */ srcSet?: string /** * The name of the avatar */ name: string } function Avatar(props: AvatarProps) { const [machineProps, localProps] = avatar.splitProps(props) const [state, send] = useMachine(avatar.machine({ id: useId() }), { context: machineProps, }) const api = avatar.connect(state, send, normalizeProps) return ( <div {...api.getRootProps()}> <span {...api.getFallbackProps()}>{getInitials(}</span> <img alt="PA" src={localProps.src} srcSet={localProps.srcSet} {...api.getImageProps()} /> </div> ) } function getInitials(name: string) { return name .split(" ") .map((word) => word[0]) .join("") }

Methods and Properties

Machine Context

The avatar machine exposes the following context properties:

  • onStatusChange(details: StatusChangeDetails) => voidFunctional called when the image loading status changes.
  • idsPartial<{ root: string; image: string; fallback: string; }>The ids of the elements in the avatar. Useful for composition.
  • idstringThe unique identifier of the machine.
  • getRootNode() => ShadowRoot | Node | DocumentA root node to correctly resolve document in custom environments. E.x.: Iframes, Electron.
  • dir"ltr" | "rtl"The document's text/writing direction.

Machine API

The avatar api exposes the following methods:

  • loadedbooleanWhether the image is loaded.
  • setSrc(src: string) => voidFunction to set new src.
  • setLoaded() => voidFunction to set loaded state.
  • setError() => voidFunction to set error state.

Data Attributes

"visible" | "hidden"
"hidden" | "visible"
