Does one simple thing - gets the flags from a regular expression. Useful for cloning and any library that uses or generates regular expressions that are created from other regular expressions.

Package Exports

  • regex-flags

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (regex-flags) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
