Quick Start with jsrepo

The easiest way to add the Notion Avatar Editor to your Svelte 5 project:

Prerequisites

Svelte 5 project
jsrepo CLI installed
bun installed (recommended, this guide uses bun but you can use npm or pnpm if you prefer)

Installation

# Install jsrepo CLI (if not already installed)
bun add -g jsrepo
 
# Initialize shadcn-svelte in your project (if not already done)
bunx shadcn-svelte@next init
 
# Add the avatar editor component
jsrepo add @stickerdaniel/notion-avatar-svelte/ui/avatar-editor

Usage

add to your +layout.svelte:

<!-- src/routes/+layout.svelte -->
<script lang="ts">
	import '../app.css';
	import { avatarContext } from '$lib/components/ui/avatar-editor/avatarContext';
	import { AvatarStoreClass } from '$lib/components/ui/avatar-editor/AvatarStore.svelte';
 
	let { children } = $props();
 
	// Instantiate and set the AvatarStore in the context
	// This makes it available to all child components within this layout.
	avatarContext.set(new AvatarStoreClass());
</script>
 
{@render children()}

and then render the Avatar Editor:

<script lang="ts">
	import AvatarCreator from '$lib/components/ui/avatar-editor/avatar-editor.svelte';
</script>
 
<AvatarCreator />

You can access the avatar context in any component:

<script lang="ts">
	import * as Avatar from '$lib/components/ui/avatar';
	import { avatarContext } from '$lib/components/ui/avatar-editor/avatarContext';
	// Get the shared avatar store
	const avatar = avatarContext.get();
</script>
 
<pre class="text-xs">{JSON.stringify(JSON.parse(avatar.configJSON), null, 2)}</pre>
<Avatar.Root>
	<Avatar.Image src={avatar.svgDataUrl} />
	<Avatar.Fallback>Avatar</Avatar.Fallback>
</Avatar.Root>

Architecture Overview

State Management

The application uses a modern state management approach with Svelte 5 Runes and the Runed library:

// Class-based store with Svelte 5 Runes
export class AvatarStoreClass implements IAvatar {
	// Reactive state with $state rune
	configJSON = $state<string>('');
 
	// Undo/Redo History tracking with Runed
	private _history: StateHistory<string>;
}

Key aspects of the state management:

Single Source of Truth: The configJSON string is the core state that drives everything
Derived Values: Computed properties using $derived reactively update when dependencies change
History Management: The StateHistory class from Runed provides undo/redo functionality
Context API: The store is made available app-wide using Runed's Context system

Customization

Theming

The project uses Tailwind CSS with customizable themes via shadcn-svelte:

Visit shadcn-svelte themes to explore and customize the color palette
Edit the src/app.css file to apply your custom theme variables
