Version 4.17.3 Details

@types/express versions 4.17.3 and 4.17.2 offer TypeScript definitions for the popular Express web application framework. These definitions enable developers to leverage the benefits of static typing within their Express.js applications, improving code maintainability and reducing runtime errors. Both versions share core functionality, providing type information for request and response objects, middleware, routing, and other essential Express features. They also depend on the same core set of supporting type definition packages: @types/body-parser, @types/serve-static, and @types/express-serve-static-core ensuring compatibility with common Express middleware.

The key difference lies in the specific version and its implications. Version 4.17.3, released in March 2020, represents a more recent iteration compared to version 4.17.2, released in November 2019. This update likely incorporates bug fixes, potentially improved type accuracy or coverage, and refinements to the existing type definitions. Developers should prefer the newer 4.17.3 to benefit from these improvements. The increase in unpacked size from 6543 to 6993 bytes suggests that 4.17.3 may include more comprehensive type definitions and potentially support new features introduced in more recent versions of Express itself or its related libraries. Developers relying on advanced express features should upgrade to ensure accurate type checking, enhanced development experience and better alignment to the express library itself.
