regexp/no-invalid-regexp | eslint-plugin-regexp

💼 This rule is enabled in the following configs: 🟢 flat/recommended, 🔵 recommended.

disallow invalid regular expression strings in RegExp constructors

This rule reports invalid regular expression patterns given to RegExp constructors.

This rule is almost functionally equivalent to ESLint's no-invalid-regexp rule. The only difference is that this rule doesn't validate flags (see no-non-standard-flag).

There are two reasons we provide this rule:

1. Better error reporting.

   Instead of reporting the whole invalid string, this rule will try to report the exact position of the syntax error.

2. Better support for complex constructor calls.

   ESLint's rule only validates RegExp constructors called with simple string literals. This rule also supports operations (e.g. string concatenation) and variables to some degree.

Nothing.
