DocuWriter.ai

Generate AI-powered documentation and code analysis

Actions6

Overview

This node, named "DocuWriter.ai," leverages AI to analyze source code and generate various outputs such as UML diagrams, code documentation, test cases, and optimized code. Specifically for the UML Diagram resource with the Generate operation, it takes source code and produces a UML diagram of a specified type. This is useful for developers and architects who want to visualize the structure or behavior of their codebase automatically without manually drawing diagrams.

Practical examples include:

  • Generating class diagrams from JavaScript or TypeScript source files to understand object-oriented design.
  • Creating sequence diagrams to visualize interactions between components or functions.
  • Producing use case diagrams to capture system requirements and user interactions.

Properties

Name Meaning
Source Code The source code text to analyze and generate the UML diagram from.
Filename The filename associated with the source code (used for context or language detection).
Diagram Type The type of UML diagram to generate. Options: Class Diagram, Sequence Diagram, Use Case Diagram, Activity Diagram, Component Diagram, State Diagram, Object Diagram.

Output

The node outputs JSON data representing the generated UML diagram. The exact structure depends on the API response but typically includes diagram data that can be rendered or further processed. The output is provided in the json field of the node's output items.

No binary data output is indicated for this operation.

Dependencies

  • Requires an external API service accessible via an authenticated HTTP request. The base URL and authentication credentials must be configured in n8n.
  • The node uses an API key credential (referred generically) to authenticate requests to the DocuWriter.ai service.
  • Network connectivity to the DocuWriter.ai API endpoint is necessary.

Troubleshooting

  • Common issues:
    • Invalid or missing API credentials will cause authentication failures.
    • Incorrect or malformed source code input may result in errors or incomplete diagrams.
    • Unsupported programming languages or very large source files might lead to timeouts or errors.
  • Error messages:
    • Errors returned from the API are surfaced as node execution errors with the message included.
    • If "Continue On Fail" is enabled, errors for individual items are returned as JSON objects with an error property describing the issue.
  • Resolutions:
    • Verify API credentials and network access.
    • Ensure source code is valid and properly formatted.
    • Reduce source code size or complexity if timeouts occur.
