Month: 2026-03. Delivered dynamic import() extension handling in TypeScript for the oxc project, aligning dynamic imports with static import behavior. Implemented transformer visitors to rewrite string-literal sources in dynamic import() expressions while preserving non-literal sources. Added test fixtures validating both rewrite and remove modes, improving build-time correctness and module resolution consistency. The changes reduce import-path errors in builds and establish groundwork for future extension handling. Commit includes AI-assisted context and co-authorship as reflected in the message.
