Advanced tools
Package description
The @babel/plugin-transform-named-capturing-groups-regex package allows Babel to transform named capturing groups in regular expressions into a format that can be understood by environments that do not support this feature natively. Named capturing groups in regular expressions provide a way to assign names to the various parts of a matched input, making the regex more readable and the matches easier to work with.
Transformation of named capturing groups
This feature allows developers to use named capturing groups in their regular expressions, which are then transformed by Babel for compatibility with environments that do not support this syntax. The code sample shows a regular expression that uses named capturing groups to match a date format.
"const regex = /(?<year>\d{4})-(?<month>\d{2})-(?<day>\d{2})/;"regexp-tree is a toolkit for working with regular expressions in JavaScript. It includes capabilities for parsing, transforming, optimizing, and generating regular expressions. While it offers a broader set of functionalities compared to @babel/plugin-transform-named-capturing-groups-regex, it can be used for similar purposes in terms of transforming regular expressions, including transformations related to named capturing groups.
xregexp provides augmented, extensible regular expressions. It includes support for additional syntax and features not found in the native JavaScript RegExp, such as named capture groups. While @babel/plugin-transform-named-capturing-groups-regex focuses on transforming existing named capturing groups for compatibility, xregexp extends the capabilities of regular expressions in JavaScript, including providing its own implementation of named capturing groups that works across all JavaScript environments.
