## Basic Setup
### Step 1: Include Dependencies
Add these to your HTML ``:
```html
```
### Step 2: Add the Widget
Before your closing `` tag:
```html
```
### Step 3: Configure Your Public Key
Open `chat.js` and locate the `CONFIG` object:
```javascript
const CONFIG = {
relays: [
'wss://relay.damus.io',
'wss://relay.primal.net',
'wss://nos.lol',
'wss://relay.btcforplebs.com',
'wss://relay.logemedia.com'
],
csPubkey: 'YOUR_PUBLIC_KEY_HERE' // Replace with your hex public key
};
```
## Getting Your Nostr Keys
### Option 1: Using an Existing Nostr Client
If you already use Nostr:
1. Open your Nostr client (Damus, Amethyst, Snort, etc.)
2. Go to Settings → Keys/Security
3. Copy your **public key** (NOT your private key)
4. If it starts with `npub1`, convert it to hex format (see below)
### Option 2: Generate New Keys
For a fresh customer support identity:
1. Install a Nostr client:
- Desktop: [Nostr.band](https://nostr.band), [Nostrudel](https://nostrudel.ninja)
- Mobile: [Damus (iOS)](https://damus.io), [Amethyst (Android)](https://github.com/vitorpamplona/amethyst)
2. Create a new account
3. **IMPORTANT**: Securely save your private key (nsec)
4. Copy your public key for the config
### Converting npub to Hex
If your public key starts with `npub1`:
**Online Tool:**
- Visit [nostr.band/tools](https://nostr.band/tools)
- Paste your npub
- Copy the hex version
**Using JavaScript:**
```javascript
import { nip19 } from 'nostr-tools';
const hex = nip19.decode('npub1...').data;
console.log(hex);
```
## Relay Configuration
### Default Relays
The widget connects to multiple relays for reliability:
```javascript
relays: [
'wss://relay.damus.io', // General purpose, reliable
'wss://relay.primal.net', // Popular, good uptime
'wss://nos.lol', // Community favorite
'wss://relay.btcforplebs.com', // Bitcoin-focused
'wss://relay.logemedia.com' // Custom relay
]
```
### Choosing Relays
**Good relays have:**
- High uptime (99%+)
- Good geographic distribution
- Support for kind 4 events (DMs)
- Read/write permissions
**Popular Relay Lists:**
- [nostr.watch](https://nostr.watch) - Relay monitoring
- [relay.tools](https://relay.tools) - Relay explorer
### Running Your Own Relay
For maximum control, run your own Nostr relay:
**Quick Setup:**
```bash
# Using nostr-rs-relay (Rust)
docker run -d -p 8080:8080 scsibug/nostr-rs-relay
# Using strfry (C++)
# See: https://github.com/hoytech/strfry
```
Then add to your config:
```javascript
relays: [
'wss://your-relay.example.com',
// ... plus backup public relays
]
```
## Customization
### Colors
The widget uses Tailwind classes. Change colors by replacing:
**Primary gradient** (orange):
```javascript
// Find in chat.js:
from-[#fdad01] to-[#ff8c00]
// Replace with your brand colors:
from-[#4F46E5] to-[#7C3AED] // Purple
from-[#10B981] to-[#059669] // Green
from-[#EF4444] to-[#DC2626] // Red
```
**Connection indicator**:
```javascript
// Green dot when connected:
bg-green-400
// Change to match your theme:
bg-blue-400
bg-purple-400
```
### Position
Change the widget position in `chat.js`:
```javascript
// Bottom-right (default)
className="fixed bottom-4 right-4 sm:bottom-6 sm:right-6"
// Bottom-left
className="fixed bottom-4 left-4 sm:bottom-6 sm:left-6"
// Top-right
className="fixed top-4 right-4 sm:top-6 sm:right-6"
```
### Branding
**Team Name:**
```javascript
// Find in chat.js render function:
Loge Media Team
// Replace with:
Your Team Name
```
**Header Title:**
```javascript
Instant Chat
// Change to:
Need Help?
```

## Advanced Configuration
### Session Duration
Change the 24-hour session expiry:
```javascript
// In getSessionKey() function:
if (Date.now() - session.created < 24 * 60 * 60 * 1000) {
// Change to 48 hours:
if (Date.now() - session.created < 48 * 60 * 60 * 1000) {
// Change to 12 hours:
if (Date.now() - session.created < 12 * 60 * 60 * 1000) {
```
### Multiple Support Accounts
Support multiple team members:
```javascript
const CONFIG = {
relays: [...],
csPubkeys: [
'team-member-1-hex-pubkey',
'team-member-2-hex-pubkey',
'team-member-3-hex-pubkey'
]
};
// Then update subscribeToReplies():
authors: CONFIG.csPubkeys
```
### Custom Welcome Message
Add an automatic welcome message:
```javascript
// In init() function, after subscribeToReplies():
setTimeout(() => {
addMessage('cs', 'Hi! How can we help you today?');
}, 500);
```
## Troubleshooting
### Widget Not Appearing
- Check browser console for errors
- Verify Tailwind CSS is loaded
- Ensure import map is correct
- Check `#chat-widget-root` div exists
### Messages Not Sending
- Verify relay connections in console
- Check public key is in hex format
- Ensure relays support kind 4 (DMs)
- Try different relays
### Not Receiving Replies
- Confirm correct private key in client
- Check relay overlap (client and widget)
- Verify DM notifications enabled
- Check client is connected to relays
### Mobile Issues
- Clear browser cache
- Check responsive CSS is applied
- Test on actual device, not just emulator
- Verify safe-area-inset for notched devices
## Security Best Practices
1. **Never expose private keys**
- Only use public keys in client code
- Store private keys securely (password manager)
- Never commit keys to version control
2. **Use HTTPS**
- Serve widget over secure connection
- Some relays require wss:// (secure websockets)
3. **Rate limiting**
- Consider implementing rate limits
- Monitor for spam/abuse
- Block abusive session keys if needed
4. **Session management**
- Sessions expire automatically
- No persistent user tracking
- Messages stored only in localStorage
