## Node Selection Guide

### By Use Case

**AI & LLM Tasks** → Use AI nodes (`nodes-ai-reference`)
- Text generation: LLMNode, OpenAINode, AnthropicNode
- Vision: VisionNode
- Audio: AudioNode
- Local LLMs: OllamaNode

**API Integration** → Use API nodes (`nodes-api-reference`)
- REST APIs: APICallNode, HTTPRequestNode
- Webhooks: WebhookNode
- GraphQL: GraphQLNode

**Custom Logic** → Use Code nodes (`nodes-code-reference`)
- Python: PythonCodeNode (recommended)
- JavaScript: JavaScriptNode
- Shell: BashNode

**Database Work** → Use Database nodes (`nodes-database-reference`)
- SQL queries: SQLQueryNode, AsyncSQLNode
- CRUD with DataFlow: Auto-generated nodes

**File Operations** → Use File nodes (`nodes-file-reference`)
- Reading files: FileReaderNode
- Bulk operations: DirectoryReaderNode
- File watching: FileWatcherNode

**Conditional Logic** → Use Logic nodes (`nodes-logic-reference`)
- Simple conditions: SwitchNode
- Complex routing: IfElseNode
- Loops: LoopNode, CycleNode

**Data Processing** → Use Data nodes (`nodes-data-reference`)
- CSV: CSVReaderNode, CSVWriterNode

## Critical Node Patterns

### String-Based API
```python
workflow.add_node("PythonCodeNode", "node1", {
    "code": "result = input_data * 2"
})
```

### Parameter Passing
```python
workflow.add_connection("node1", "result", "node2", "input_data")
```

### Common Nodes
- **PythonCodeNode**: Most flexible, use for custom logic
- **SwitchNode**: Conditional routing based on values
- **CSVReaderNode**: Reading CSV files
- **APICallNode**: HTTP API calls
- **LoggerNode**: Debug and production logging
