is-glob  

Returns true if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a better user experience.

Also take a look at is-valid-glob and has-glob.

Install

Install with npm

sh
$ npm i is-glob --save

Usage

js
var isGlob = require('is-glob');

True

Patterns that have glob characters or regex patterns will return true:

js
isGlob('!foo.js');
isGlob('*.js');
isGlob('**/abc.js');
isGlob('abc/*.js');
isGlob('abc/(aaa|bbb).js');
isGlob('abc/[a-z].js');
isGlob('abc/{a,b}.js');
isGlob('abc/?.js');
//=> true

Extglobs

js
isGlob('abc/@(a).js');
isGlob('abc/!(a).js');
isGlob('abc/+(a).js');
isGlob('abc/*(a).js');
isGlob('abc/?(a).js');
//=> true

False

Patterns that do not have glob patterns return false:

js
isGlob('abc.js');
isGlob('abc/def/ghi.js');
isGlob('foo.js');
isGlob('abc/@.js');
isGlob('abc/+.js');
isGlob();
isGlob(null);
//=> false

Arrays are also false (If you want to check if an array has a glob pattern, use has-glob):

js
isGlob(['**/*.js']);
isGlob(['foo.js']);
//=> false
