What is JDT?

JSON Document Transforms (JDT) is a specification for transforming JSON files using another JSON file as the transformation specification. The default behavior is to merge the transformation into the source, with advanced operations available through transformation verbs.

Transform Verbs:

• @jdt.merge - Merge values into the source
• @jdt.replace - Replace values in the source
• @jdt.remove - Remove values from the source
• @jdt.rename - Rename keys in the source

Key Features:

• JSONPath support for targeting specific nodes
• Recursive transformations for nested objects
• Filter expressions for conditional operations
• WebAssembly support for browser/Node.js usage
