Read File

​

Node Details

• Name: ReadFile
• Type: Tool
• Version: 1.0
• Category: Tools

​

Base Classes

• ReadFile
• Tool
• StructuredTool
• Serializable

​

Parameters

• Base Path
  • Label: Base Path
  • Name: basePath
  • Type: string
  • Optional: true
  • Placeholder: C:\Users\User\Desktop
  • Description: The base directory path from which files will be read. If not provided, the default system path will be used.

​

Functionality

1. The node initializes a NodeFileStore instance, either with the provided base path or using the default path.
2. It creates a ReadFileTool instance, which is the core component for reading files.
3. The ReadFileTool uses a schema to validate input, expecting a file_path string.
4. When called, the tool reads the contents of the specified file using the store.readFile() method.

​

Input/Output

• Input: A file path (string) representing the file to be read.
• Output: The contents of the file as a string.

​

Usage

• Reading configuration files
• Processing text files
• Accessing data stored in files for further analysis or manipulation

​

Implementation Details

• The node uses Zod for input validation.
• It extends the StructuredTool class from the LangChain library.
• File operations are abstracted through the BaseFileStore class, with NodeFileStore providing the concrete implementation for Node.js environments.

Error Handling

Notes

• The actual file reading operation is performed by the NodeFileStore class, which is not fully visible in the provided code snippet.
• This tool is designed to work within a larger system, likely integrating with other nodes or tools for complex workflows.
