# Obsidian Webhooks & Events

## Overview
Comprehensive guide to handling events in Obsidian plugins - workspace events, vault events, and custom event patterns.

## Prerequisites
- Understanding of Obsidian plugin lifecycle
- Familiarity with TypeScript event patterns
- Basic plugin setup completed

## Instructions

### Step 1: Workspace Events

### Step 2: Vault Events

### Step 3: MetadataCache Events

### Step 4: Debounced Event Handling

### Step 5: Custom Event Emitter

### Step 6: File Watcher Pattern

For full implementation details and code examples, load:
`references/implementation-guide.md`

## Output
- Workspace event handlers for UI state
- Vault event handlers for file operations
- MetadataCache handlers for content changes
- Debounced handlers for frequent events
- Custom event bus for internal communication
- Filtered file watchers

## Error Handling
| Issue | Cause | Solution |
|-------|-------|----------|
| Memory leak | Unregistered events | Use `registerEvent` |
| Performance issues | Too many handlers | Debounce frequent events |
| Missed events | Late registration | Register in `onload` |
| Stale data | Cache not updated | Use `metadataCache.on('changed')` |
