Automated Type Inference & Interface Generation

KlypX recursively analyzes the JSON object graph, inferring scalar types (string, number, boolean, null), compound structures (nested interfaces), and arrays (primitive arrays or object item interfaces). Root interfaces and sub-models are generated with clean PascalCase naming and optional properties where fields contain null values.

Handling Union Types & Heterogeneous Arrays

When array elements contain mixed types, KlypX inspects the union of all child properties to construct a safe TypeScript type definition. This reduces manual interface authoring when integrating third-party APIs like Stripe, GitHub, or Shopify.
