A full version history of the @types/express package with size, number of distributed files and dependency evolution.
The @types/express package provides TypeScript definitions for the Express.js framework, a popular Node.js web application framework. Examining its version history reveals an evolving codebase, reflecting the development of both Express itself and the TypeScript language. Versions 4.0.29 through 4.0.39, released in 2016 and 2017, primarily focused on providing type definitions for Express 4.x. The dependency @types/express-serve-static-core remained consistent across these early versions, indicating a stable core API.
Significant version bumps, such as moving from 4.0.x to 4.11.x and then 4.16.x, introduced new features and refinements to the type definitions. For example, versions 4.0.38 and later added a dependency on @types/body-parser, reflecting a common usage pattern in Express applications.
The 4.17.x line, spanning from 2019 to 2023, saw incremental improvements and updates, including a dependency on @types/qs starting with version 4.17.4, reflecting the growing use of query string parsing in web applications. The later versions of the 4.17.x line also began pointing to express-serve-static-core version ^4.17.31, indicating a dependency on a specific, later version of the core static server definitions.
Finally, the 5.0.x releases represent a major version update, aligning with Express.js version 5, and include the same dependency with express-serve-static-core version ^5.0.0.
