Spade SDK provides basic classes to implement Spade Files and Processes. For more information about Spade, please visit Spade

It has no dependencies on other Python libraries, and allows development for Spade without a need to install the full Spade app.

pip install spadesdk

For file validation functionality, install with the pandera extra:

pip install spadesdk[pandera]

FileProcessor processes the file uploaded by the user in the Spade app.

The FileProcessor class includes a static validate method that can validate file data against a schema using the Pandera library. This method validates DataFrame data against a Frictionless schema defined in the File object.

Requirements:

• The spadesdk[pandera] package must be installed (available as an optional dependency)
• A valid Frictionless schema must be defined in Spade

# Validate DataFrame against the schema
FileProcessor.validate(file, dataframe)

Note: If Pandera is not installed, calling the validate method will raise an ImportError.

Executor executes a Spade process, either by directly running Python code or by calling an external service.

HistoryProvider provides the history of a Spade from if the actual process is executed by an external service. If the process is executed in Spade, a HistoryProvider is not needed.
