Webpack Merge evolved significantly between versions 4.2.2 and 5.0.0, reflecting changes in the JavaScript ecosystem and tooling. The upgrade involved a shift in dependencies, indicating a move towards modern development practices. Version 4.2.2 relied on Lodash for utility functions, a common practice at the time. The transition to version 5.0.0 replaced Lodash with "wildcard" and "clone-deep", suggesting a potential move towards smaller, more focused dependencies. This change can reduce the overall bundle size and improve performance for users of the library.
Moreover, the developer tooling saw a major overhaul. The older version used Babel, ESLint and a range of related plugins for transpilation and linting - common tools for maintaining code quality in older JavaScript projects. In contrast, version 5.0.0 adopted TSDX and TypeScript, accompanied with type definitions for Webpack showcasing a commitment to modern TypeScript development. This allows developers to leverage static typing and modern JavaScript features improving the development experience and code maintainability. The updated version provides better type safety and autocompletion. Webpack Merge 5.0.0 appears to be optimized for projects using TypeScript and modern Webpack versions, promising better integration and a smoother development workflow for TypeScript users.
