Package description
The @babel/plugin-transform-unicode-sets-regex package is a plugin for Babel, a JavaScript compiler, that transforms Unicode property escapes in regular expressions to a set of BMP characters and sequences that can be understood by JavaScript engines without native support for Unicode property escapes. This allows developers to write regular expressions using the latest JavaScript features while ensuring compatibility with older environments.
Transform Unicode property escapes
This feature allows developers to use Unicode property escapes in regular expressions, which are then transformed into a compatible format. For example, the regex /\p{Script=Greek}/u matches any character that is part of the Greek script. The plugin will transform this into an equivalent regex that does not use the Unicode property escape syntax, allowing it to run in environments that do not support this feature natively.
/\p{Script=Greek}/uThe regexpu-core package is a regular expression polyfill that also transforms Unicode property escapes. It is similar to @babel/plugin-transform-unicode-sets-regex but can be used independently of Babel. It provides a function that takes a string (a regular expression pattern) and returns a new string with transformed Unicode property escapes.
This Babel plugin transforms new RegExp() constructors by replacing any patterns that include Unicode property escapes with transpiled versions. It is similar to @babel/plugin-transform-unicode-sets-regex but focuses on RegExp constructors rather than literals.
