Dropbox: monitor folder and document new files

Dropbox: monitor folder and document new files

This workflow automates the documentation of newly added or modified code files in a Dropbox folder. Every 15 minutes it scans a target directory, filters for recent code changes, leverages DocuWriter.ai to generate documentation, comments, and UML diagrams, then uploads the outputs back to Dropbox, updates an index, creates a shareable link, and notifies the team via Slack and email.

Nodes and Descriptions

Key Configuration Snippet

{
  "id": "file-monitor-schedule",
  "name": "File Monitor Schedule (15min)",
  "type": "n8n-nodes-base.cron",
  "typeVersion": 1,
  "parameters": {
    "minutesInterval": 15
  }
}

This cron node ensures the workflow runs every 15 minutes .

Adaptation Tips

• Folder Path: Change the path in Scan Dropbox Code Folder to monitor a different directory.
• Time Window: Adjust the filter logic duration (currently 15 minutes) in Filter New Code Files.
• Generation Instructions: Tweak prompts in Generate Documentation, Code Comments, and UML Diagrams for custom requirements.
• Notification Channels: Swap Slack or Gmail nodes with Teams, Discord, or SMS integrations as needed.
• Indexing: Enhance documentation-index.json schema to include tags, reviewers, or status flags.

By adapting parameters and nodes, you can repurpose this template for other cloud storage providers (e.g., Google Drive) or different output formats.
