## Features

- Connect to any Mumble server over TLS
- Manage channels: create, remove, link/unlink, fetch ACLs
- Manage users: move, mute/deafen, register/deregister, rename
- Query channel permissions
- Event-driven architecture with full TypeScript support
- Automatic keep-alive pinging

## Installation

```bash
npm i @tf2pickup-org/mumble-client
```

## Quick start

```typescript
import { Client } from '@tf2pickup-org/mumble-client';

const client = new Client({
  host: 'mumble.example.com',
  port: 64738,
  username: 'my-bot',
  rejectUnauthorized: false,
});

await client.connect();
console.log(`Connected! Welcome message: ${client.welcomeText}`);
console.log(`Logged in as ${client.self?.name}`);

// ... do work ...

client.disconnect();
```

## Examples

### Connect with a password and access tokens

```typescript
const client = new Client({
  host: 'mumble.example.com',
  port: 64738,
  username: 'my-bot',
  password: 'server-password',
  tokens: ['token-for-acl-group'],
  clientName: 'my-awesome-bot',
  rejectUnauthorized: false,
});

await client.connect();
```

### List all channels

```typescript
import { type Channel } from '@tf2pickup-org/mumble-client';

function printChannel(channel: Channel, level = 0) {
  if (channel.name) {
    console.log(' '.repeat(level * 2) + channel.name);
  }

  for (const subChannel of channel.subChannels) {
    printChannel(subChannel, level + 1);
  }
}

printChannel(client.channels.root);
```

### Find a channel

```typescript
// by name
const lobby = client.channels.byName('Lobby');

// by path (from root)
const redTeam = client.channels.byPath('Match 1', 'RED');

// by custom predicate
const tempChannels = client.channels.findAll(ch => ch.temporary);
```

### Create and manage channels

```typescript
const root = client.channels.root;

// create a sub-channel under root
const matchChannel = await root.createSubChannel('Match 1');

// create team channels
const red = await matchChannel.createSubChannel('RED');
const blu = await matchChannel.createSubChannel('BLU');

// link two channels together
await red.link(blu);

// unlink them
await red.unlink(blu);

// remove a channel (and all its sub-channels)
await matchChannel.remove();
```

### Move users between channels

```typescript
const user = client.users.byName('PlayerOne');
const targetChannel = client.channels.byName('RED');

if (user && targetChannel) {
  await user.moveToChannel(targetChannel.id);
}
```

### Mute/deafen yourself

```typescript
// self-mute
await client.self.setSelfMute(true);

// self-deafen
await client.self.setSelfDeaf(true);

// unmute
await client.self.setSelfMute(false);
```

### Register and manage users

```typescript
// register the currently logged-in user
await client.self.register();

// fetch all registered users from the server
const registeredUsers = await client.fetchRegisteredUsers();
for (const user of registeredUsers) {
  console.log(`${user.userId}: ${user.name}`);
}

// rename a registered user (does not need to be online)
await client.renameRegisteredUser(userId, 'NewName');

// deregister a user (does not need to be online)
await client.deregisterUser(userId);
```

### Check channel permissions

```typescript
const channel = client.channels.byName('Lobby');
if (channel) {
  const permissions = await channel.getPermissions();
  console.log('Can join:', permissions.canJoinChannel);
  console.log('Can create sub-channels:', permissions.canCreateChannel);
  console.log('Can remove:', permissions.canRemoveChannel);
  console.log('Can link:', permissions.canLinkChannel);
}
```

### Listen to events

```typescript
// user connected
client.on('userCreate', user => {
  console.log(`${user.name} connected`);
});

// user disconnected
client.on('userRemove', user => {
  console.log(`${user.name} disconnected`);
});

// user state changed (e.g. moved channel, muted, etc.)
client.on('userUpdate', (user, changes) => {
  if (changes.channelId) {
    const from = client.channels.byId(changes.channelId.previousValue);
    const to = client.channels.byId(changes.channelId.currentValue);
    console.log(`${user.name} moved from ${from?.name} to ${to?.name}`);
  }
});

// channel created
client.on('channelCreate', channel => {
  console.log(`Channel created: ${channel.name}`);
});

// channel removed
client.on('channelRemove', channel => {
  console.log(`Channel removed: ${channel.name}`);
});

// speaking state changes
client.on('speakingStateChange', ({ user, speaking }) => {
  console.log(`${user.name} ${speaking ? 'started' : 'stopped'} speaking`);
});

// disconnected from server
client.on('disconnect', payload => {
  console.log(`Disconnected: ${payload?.reason ?? 'unknown reason'}`);
});
```

### Error handling

```typescript
import {
  Client,
  ConnectionRejectedError,
  PermissionDeniedError,
  NoSuchChannelError,
} from '@tf2pickup-org/mumble-client';

try {
  await client.connect();
} catch (error) {
  if (error instanceof ConnectionRejectedError) {
    console.error('Connection rejected by server');
  }
}

try {
  await client.channels.root.createSubChannel('test');
} catch (error) {
  if (error instanceof PermissionDeniedError) {
    console.error('Insufficient permissions to create channel');
  }
}
```
