Debugging Logic Apps Data Mapper XSLT Locally

Debugging Azure Logic Apps Data Mapper transformations can be challenging due to limited visibility. The XSLT Debugger extension for VS Code offers a solution with local debugging capabilities. By configuring a launch.json file, developers can debug the generated XSLT without affecting existing Logic Apps. The workflow involves editing the data mapper, saving it to generate XSLT, and then initiating the debugger. Developers can set breakpoints, inspect variables, and evaluate XPath expressions in real-time. The debugger utilizes the same .NET XSLT 1.0 engine as Azure Logic Apps, ensuring consistency between local and production environments. Key features include auto-captured variables, XPath watch expressions, and step-through debugging. This enables developers to view the transformation output and debug logs, significantly improving development speed and reducing bugs. Local debugging provides faster iteration, better visibility, and reduces the need for trial-and-error deployments.
