Generate AI-powered documentation and code analysis

Actions6

Overview

This node performs AI-powered code optimization by analyzing and refactoring source code to improve various aspects such as performance, readability, maintainability, or security. It is useful for developers who want to automatically enhance their code quality without manual intervention. For example, you can input a JavaScript file and request optimizations focused on improving performance or making the code easier to read and maintain.

Typical use cases include:

  • Automatically refactoring legacy code to improve maintainability.
  • Enhancing performance-critical sections of code.
  • Improving code readability for better team collaboration.
  • Applying security best practices to reduce vulnerabilities.

Properties

Name Meaning
Source Code The source code text to be analyzed and optimized.
Filename The filename associated with the source code (used for context or language detection).
Optimization Focus The focus area for optimization. Options: All, Performance, Readability, Maintainability, Security

Output

The node outputs a JSON object containing the optimized version of the provided source code. This typically includes the refactored code text and may also contain metadata about the changes made or suggestions applied.

The output JSON structure corresponds to the API response from the optimization endpoint and is returned as an array of JSON objects, each representing the result for one input item.

No binary data output is produced by this node.

Dependencies

  • Requires an API key credential for authentication with the external DocuWriter.ai service.
  • The node makes HTTP POST requests to the /api/n8n/optimize-code endpoint of the configured base URL for the DocuWriter.ai API.
  • Proper network connectivity and valid credentials are necessary for successful operation.

Troubleshooting

  • Common issues:

    • Invalid or missing API credentials will cause authentication failures.
    • Providing empty or syntactically invalid source code may lead to errors or no meaningful optimization.
    • Network connectivity problems can prevent the node from reaching the API endpoint.

  • Error messages:

    • Errors returned from the API will be surfaced as node execution errors unless "Continue On Fail" is enabled.
    • Typical error messages might include authentication errors, invalid parameter errors, or server-side processing errors.

  • Resolutions:

    • Ensure that a valid API key credential is configured in n8n.
    • Verify that the source code input is correctly formatted and non-empty.
    • Check network access and firewall settings to allow outbound requests to the API service.
