How to Use the 'npm search' Command (with Examples)
The npm search command is a powerful tool for developers looking to explore the vast repository of packages available on the npm (Node Package Manager) registry. With npm being one of the largest package ecosystems, this command enables users to efficiently find packages that fit their needs by searching for specific package names, keywords, authors, or scopes. This article will guide you through various use cases of the npm search command, with examples to help you make the most of it.
