Version Details and Security Vulnerabilities

The @types/hast package provides TypeScript definitions for hast, a unified syntax tree format representing HTML. Version 3.0.4 was released on January 30, 2024, following version 3.0.3, which was released on November 7, 2023. While both versions share the same core description and MIT license, they represent incremental updates to the type definitions. Both rely on the "@types/unist" package, indicating a dependency on the Unified ecosystem's underlying data structure. The key difference lies in the details of the distribution ("dist") object. Version 3.0.4 has a slightly smaller unpacked size of 9703 bytes compared to version 3.0.3's 9723 bytes, suggesting minor optimizations or refactorings in the type definitions. Developers using the library benefit from these refinements, as they ensure accurate type checking and improved code completion within their projects that manipulate HTML using hast. Upgrading to version 3.0.4 promises potentially a slightly leaner footprint. The release date difference suggests a period of about three months between updates, implying regular maintenance and improvements by the DefinitelyTyped contributors. For developers already using @types/hast, upgrading should be straightforward, and will provide a modern set of type definitions aligned with potential updates to hast. Developers working with HTML AST and TypeScript environments should leverage these type definitions for robust and maintainable code.
