The @types/node package provides TypeScript definitions for Node.js, enabling developers to leverage the benefits of static typing within their Node.js projects. Version 22.15.19 was released on May 19, 2025, a few days after version 22.15.18 which came out on May 14, 2025. Both versions share the same core dependency on "undici-types" at version "~6.21.0", indicating that the underlying definitions for the undici HTTP client library remain consistent. The fundamental structure and licensing, MIT, remain the same across these versions, with the source code maintained in the DefinitelyTyped repository on GitHub.
The most significant difference lies in the "dist" object which is the packaged distribution of the version in npm: version 22.15.19 has an unpacked size of 2,354,451 bytes, while version 22.15.18 has an unpacked size of 2,354,450 bytes. The file count remains at 76. Although seemingly small, this 1 byte difference in unpacked size could hint at minor updates or fixes somewhere inside of the package, most likely related to specific type definitions.
For developers choosing between these versions, the decision hinges on whether the latest version (22.15.19) addresses any specific issues or provides necessary type clarifications encountered while using version 22.15.18. For projects already utilizing 22.15.18 and experiencing no type-related problems, upgrading is likely unnecessary. However, staying current with the newest release ensures access to the most up-to-date and potentially refined type definitions, which could improve code maintainability and prevent subtle type-related errors. Due the very small difference, the changes are likely very small.
