Avoid re-export all.
Deeply nested import chains in modular projects, where a barrel file imports another barrel file, can lead to increased load times and complexity. This structure results in the unnecessary loading of many modules, significantly impacting performance in large-scale applications. Additionally, it complicates the codebase, making it difficult to navigate and understand the project’s dependency graph.
