    Making Changes and Rebuilding Locally

    Refer to the n8n docs on how to run nodes locally: docs

    1. Make your changes to the code (e.g., in nodes/Telli/Telli.node.ts)

    2. Build the project:

    npm run build
    

    3. Copy the built files to your n8n custom directory:

    cp -r dist/* ~/.n8n/custom/n8n-nodes-telli/ # or wherever your custom directory is
    

    4. Restart n8n to see your changes:

    First kill the current n8n process (Ctrl+C), then run:

    n8n start

    Development Workflow Tips

  • Use npm run dev to continuously build the code as you make changes
  • Check for linting errors with npm run lint
  • Format code with npm run format

Troubleshooting

If you don’t see your changes after rebuilding and restarting n8n:

1. Check if there are any errors in the n8n logs
2. Verify that the files were correctly copied to the custom directory
3. Make sure n8n was properly restarted
4. Clear your browser cache or open n8n in an incognito window
