comment-regex

Regular expression for matching JavaScript comments

This is pretty fragile and created for performance reasons where using a real parser would be overkill. Do not use it with untrusted user input.

Install

npm install comment-regex

Usage

import {commentRegex} from 'comment-regex';

// Contains a comment
commentRegex().test('/* unicorn */\nvar foo = true;');
//=> true

// Get the contents of a comment
commentRegex().exec('/* unicorn */\nvar foo = true;')[2].trim();

// Get all the comments
'/* unicorn */\nvar foo = true;\nvar unicorn = "rainbows"; // rainbow'.match(commentRegex());
//=> ['/* unicorn */', ' // rainbow']
