@babel/plugin-transform-sticky-regex
Advanced tools
Package description
The @babel/plugin-transform-sticky-regex package is a plugin for Babel, a JavaScript compiler, that transforms sticky regexes (regular expressions with the 'y' flag) into an equivalent form that can be executed in environments that do not support the 'y' flag. This ensures compatibility across different JavaScript environments, including older browsers or JavaScript engines.
Transformation of sticky regexes
This feature allows the transformation of sticky regexes, which use the 'y' flag, into a form that can be executed in environments that do not support this flag. The code sample demonstrates how a sticky regex is transformed by the plugin.
"use strict";\n\nvar _regexp = /o+/y;\n\nvar _regexp2 = babelHelpers.wrapRegExp(/o+/, {\n sticky: true\n});Similar to @babel/plugin-transform-sticky-regex, this plugin transforms regex constructors to ensure compatibility across different environments. While @babel/plugin-transform-sticky-regex focuses specifically on sticky regexes, @babel/plugin-transform-regex-constructors targets the transformation of regex constructors, potentially including flags like 'y'.
This package is a part of the regexpu project, which is a collection of tools to process regular expressions. While not a direct plugin for Babel, regexpu-core can transform ES2015 Unicode regular expressions into equivalent ES5 syntax. It covers a broader range of regex features, including but not limited to sticky regexes, making it a more comprehensive solution for regex compatibility issues.
