In March 2026, Pgn enhanced the hey-api/openapi-ts repository by improving OpenAPI discriminator handling to increase type accuracy and cross-version compatibility. Focusing on TypeScript and OpenAPI Specification, Pgn refactored the mapping logic so that inline discriminator mappings take precedence over referenced schemas, and added support for self-mapping discriminators. The work included targeted fixes for nested allOf scenarios, reducing incorrect $type literals and improving client code generation reliability. Comprehensive tests were implemented across both 3.0.x and 3.1.x parsers using JSON and TypeScript, ensuring the changes were robust and maintainable while simplifying future maintenance and validating cross-version behavior.

Mar 1, 2026March 2026 (2026-03) focused on strengthening the OpenAPI discriminator handling in hey-api/openapi-ts to boost type accuracy, reliability, and cross-version compatibility. Delivered a suite of improvements that ensure inline discriminator mappings take precedence over referenced schemas, added support for self-mapping discriminators, and refactored discriminator property handling for clarity and performance. Implemented tests across 3.0.x and 3.1.x parsers to validate changes and prevent regressions. The changes reduce incorrect $type literals, improve client code generation reliability, and simplify maintenance. The work included targeted fixes to the mapping logic observed in nested allOf scenarios and self-mapped discriminators, with minimal reproduction specs and snapshot tests for both parsers.
