@typescript-eslint/parser version 4.22.1 is a patch release building upon the previous stable version 4.22.0, both serving as custom ESLint parsers leveraging TypeScript ESTree. Essentially, they enable ESLint to understand and analyze TypeScript code. Both versions share the same core functionality and dependencies, including debug for debugging, @typescript-eslint/types, @typescript-eslint/scope-manager, and @typescript-eslint/typescript-estree for type information, scope management, and ESTree conversion respectively. Development dependencies like glob, typescript, and @types/glob remain consistent, facilitating streamlined development workflows. Peer dependencies specify compatible ESLint versions (5.x, 6.x, and 7.x).
The key difference resides in potential bug fixes, minor enhancements, or performance improvements introduced in 4.22.1. Examining the changes between them could reveal that version 4.22.1 improves stability and fixes specific edge cases encountered in the previous version, ensuring a smoother and more reliable linting experience. While the unpacked size has increased slightly from 63160 to 63339, it doesn't necessarily indicate vast structural changes. The release date difference marks when version 4.22.1 became available. Developers should consider upgrading to 4.22.1, especially if they've experienced issues with 4.22.0, intending for the bug fixes. As with any patch release, review the changelog for the specifics to understand the scope of refinements.
