eslint/no-regex-spaces Restriction

🚧 An auto-fix is still under development.

What it does

Disallow 2+ consecutive spaces in regular expressions.

Why is this bad?

In a regular expression, it is hard to tell how many spaces are intended to be matched. It is better to use only one space and then specify how many spaces are expected using a quantifier.

var re = /foo {3}bar/;

Example

var re = /foo   bar/;

How to use

To enable this rule in the CLI or using the config file, you can use:

CLI

oxlint --deny no-regex-spaces

Config (.oxlintrc.json)

{
  "rules": {
    "no-regex-spaces": "error"
  }
}
