Root causes of previous issues: 1. Jumping behavior: The old implementation used setState() directly to random positions instead of interpolating toward them. Each idle movement instantly teleported the eyes. 2. Mouse tracking failure: The updateMouseTracking callback had isTracking in its dependencies, causing it to be recreated on every state change. This restarted the animation frame loop constantly, breaking the continuous tracking. 3. State conflict: Idle timeouts and tracking animation frames ran independently and fought each other, causing erratic behavior. Solution - Single animation loop architecture: - ONE requestAnimationFrame loop handles ALL animation - Maintains separate 'current' and 'target' positions - Always interpolates: current = lerp(current, target, smoothing) - Idle behavior only sets new targets (doesn't move directly) - Mouse tracking overrides targets when cursor is nearby - Clean state machine: tracking active = idle paused Smoothing values used: - IDLE_SMOOTHING = 0.03 (very smooth drift) - TRACKING_SMOOTHING = 0.08 (responsive but not snappy) - RETURN_SMOOTHING = 0.04 (gentle return to idle) Timing improvements: - Idle duration: 3-6 seconds between movements - 40% chance to pause at center (natural resting) - Time-scaled smoothing for consistent feel across frame rates Movement constraints: - Baby: 2px max, Adult: 2.5px max - Vertical movement reduced to 70% of horizontal - State updates throttled (only when position changes > 0.001px)
Ditto
Your content. Your vibe. Your rules. A fun, customizable Nostr client that puts you in control.
About
Ditto is an open-source, decentralized social media client built on the Nostr protocol. It's designed for people who want to have fun online without feeding the Big Tech machine. Express yourself with custom themes, Lightning payments, and an ever-growing set of content types -- all while owning your identity and data.
Made by Soapbox.
Features
- Theming -- 9 built-in theme presets, 19 CSS token properties for full customization, and the ability to publish and share themes as Nostr events
- Infinite Content Types -- Text notes, articles, short-form videos (Vines), live streams, polls, follow packs, color moments, magic decks, geocaching, and Webxdc mini-apps
- Lightning Payments -- Zap posts and profiles with sats via Nostr Wallet Connect (NWC) or WebLN
- Private Messaging -- End-to-end encrypted DMs (NIP-04 and NIP-17)
- Comments -- Comment on anything: posts, URLs, profiles, hashtags, books, and more (NIP-22)
- Self-Hosting -- Builds to static HTML/JS/CSS. Deploy anywhere -- GitHub Pages, Netlify, Vercel, a VPS, or a Raspberry Pi
- Mobile -- Android native app via Capacitor, responsive design for all screen sizes
Getting Started
Prerequisites
- Node.js 22+
- npm 10.9.4+
Development
git clone https://gitlab.com/soapbox-pub/ditto.git
cd ditto
npm install
npm run dev
The dev server starts at http://localhost:8080.
Build
npm run build
The built site is output to dist/.
Test
Runs type-checking, linting, unit tests, and a production build:
npm test
Configuration
Ditto is configured through a ditto.json file at the project root, read at build time. This file is gitignored so each deployment can have its own configuration.
{
"theme": "dark",
"relayMetadata": {
"relays": [
{ "url": "wss://relay.ditto.pub", "read": true, "write": true }
]
},
"blossomServers": ["https://blossom.ditto.pub"],
"feedSettings": {
"showPosts": true,
"showReposts": true,
"showArticles": true
// ...and more content type toggles
}
}
Configuration is resolved in three layers (highest priority first):
- User settings stored in localStorage
- Build config from
ditto.json - Hardcoded defaults
Use an alternate config file path with: CONFIG_FILE=./my-config.json npm run build
Custom Branding
For self-hosted instances:
- Replace
public/logo.svgandpublic/logo.pngwith your logo - Update the app name in
index.htmlandpublic/manifest.webmanifest - Replace
public/og-image.jpgfor social sharing previews - Set default relays and upload servers in
ditto.json
Deployment
Ditto builds to static files and can be deployed anywhere that serves HTML.
- GitHub Pages / GitLab Pages -- Push to
mainand CI auto-deploys - Netlify / Vercel -- Connect your fork and deploy. A
_redirectsfile is included for SPA routing - VPS / Any web server -- Build and copy
dist/to your server. Configure SPA routing (e.g., Nginxtry_files $uri $uri/ /index.html)
Android
Build a native Android app with Capacitor:
npm run build
npx cap sync
npx cap open android
