babel-helper-regex
Advanced tools
Package description
The babel-helper-regex package is a utility module used by Babel plugins to help with the manipulation and optimization of regular expressions. It provides functions to modify regex patterns and flags, which is particularly useful when developing custom Babel transformations that involve regular expressions.
Optimize regex literals
This feature allows the optimization of regular expressions by collapsing redundant patterns and ensuring the most efficient regex is used. This can improve performance and reduce the size of the regex.
import { optimizeRegexLiteral } from 'babel-helper-regex';
const optimizedRegex = optimizeRegexLiteral(/foo|foo/g);
console.log(optimizedRegex); // Output might be optimized version of regexregexp-tree is a toolkit for handling, parsing, and transforming regular expressions. It provides a more comprehensive set of tools compared to babel-helper-regex, including an AST for regex patterns, which allows for more complex manipulations and optimizations.
safe-regex is a package that checks if a regular expression is safe and not susceptible to ReDoS (Regular Expression Denial of Service) attacks. While babel-helper-regex focuses on optimization and modification, safe-regex provides security insights, which can be crucial for applications processing user-generated patterns.
