npm-search man page
npm-search — Search for packages
npm search [-l|--long] [search terms ...] aliases: s, se, find
Search the registry for packages matching the search terms.
If a term starts with /, then it's interpreted as a regular expression. A trailing / will be ignored in this case. (Note that many regular expression characters must be escaped or quoted in most shells.)
Display full package descriptions and other long text across multiple lines. When disabled (default) search results are truncated to fit neatly on a single line. Modules with extremely long names will fall on multiple lines.
Type : url
Search the specified registry for modules. If you have configured npm to point to a different default registry, such as your internal private module repository, npm search will default to that registry when searching. Pass a different registry url such as the default above in order to override this setting.
