eslint/no-regex-spaces Restriction

🛠️ An auto-fix is available for this rule.

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/;

Examples

Examples of incorrect code for this rule:

var re = /foo   bar/;

How to use

Config (.oxlintrc.json)

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