Detect File

Detects the MIME type of a file using the mimetype library.

Common Properties​

  • Name - The custom name of the node.
  • Color - The custom color of the node.
  • Delay Before (sec) - Waits in seconds before executing the node.
  • Delay After (sec) - Waits in seconds after executing node.
  • Continue On Error - Automation will continue regardless of any error. The default value is false.
info

If the ContinueOnError property is true, no error is caught when the project is executed, even if a Catch node is used.

Inputs​

  • File Path - The path to the file for which to detect the MIME type.

Output​

  • MIME Type - The detected MIME type of the file.

How It Works​

The Detect File node uses the mimetype library to analyze a file and determine its MIME type. When executed, the node:

  1. Validates the provided file path input
  2. Uses the mimetype.DetectFile function to analyze the file
  3. Returns the detected MIME type as a string

Requirements​

  • A valid file path to analyze
  • The file must be accessible by the application

Error Handling​

The node will return specific errors in the following cases:

  • Empty or invalid file path
  • File not found or inaccessible
  • Error during MIME type detection

Usage Notes​

  • The MIME type detection is based on the file content, not just the file extension
  • The node supports a wide range of file formats including documents, images, audio, video, and more
  • The detected MIME type follows the standard MIME type format (e.g., "text/plain", "image/jpeg", "application/pdf")
