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 bet
The is-glob npm package is used to determine if a string is a glob pattern. A glob pattern is a string that defines a pattern for matching file names, typically used for file searching and manipulation. The package provides a simple API to check if a string contains characters that make it a valid glob pattern.
Check if a string is a glob pattern
This feature allows you to check if a given string is a glob pattern. It returns true if the string contains special characters like '*', '?', or '[...]' that are used in glob patterns, and false otherwise.
const isGlob = require('is-glob');
console.log(isGlob('*.js')); // true
console.log(isGlob('hello.txt')); // falseCheck if an array contains a glob pattern
This feature checks if any element in an array is a glob pattern. It returns true if at least one element is a glob pattern, and false if none are.
const isGlob = require('is-glob');
console.log(isGlob(['css', '*.js'])); // true
console.log(isGlob(['css', 'js'])); // falseMicromatch is a powerful, high-performance library for matching strings with glob patterns. It is more feature-rich than is-glob, providing advanced pattern matching, filtering, and conversion capabilities.
Minimatch is a minimal matching utility that implements the same glob pattern matching rules as used by npm. It is similar to is-glob but also includes the ability to match patterns against strings, not just check if a string is a glob.
Globby is a user-friendly glob matching utility built on top of micromatch. It extends the basic functionality of is-glob by providing methods to find files and directories in the file system using glob patterns.
Node-glob is a full-featured glob library that can match strings against patterns and also find files in the filesystem that match a given glob. It is more comprehensive than is-glob, which only checks if a string is a glob pattern.
Returns
trueif 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.

var isGlob = require('is-glob');
True
Patterns that have glob characters or regex patterns will return true:
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');
//=> true
Extglobs
isGlob('abc/@(a).js');
isGlob('abc/!(a).js');
isGlob('abc/+(a).js');
isGlob('abc/*(a).js');
isGlob('abc/?(a).js');
//=> true
False
Escaped globs or extglobs return false:
isGlob('abc/\\@(a).js');
isGlob('abc/\\!(a).js');
isGlob('abc/\\+(a).js');
isGlob('abc/\\*(a).js');
isGlob('abc/\\?(a).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');
//=> false
Patterns that do not have glob patterns return false:
isGlob('abc.js');
isGlob('abc/def/ghi.js');
isGlob('foo.js');
isGlob('abc/@.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):
isGlob(['**/*.js']);
isGlob(['foo.js']);
//=> false
When options.strict === false the behavior is less strict in determining if a pattern is a glob. Meaning that
some patterns that would return false may return true. This is done so that matching libraries like micromatch have a chance at determining if the pattern is a glob or not.
True
Patterns that have glob characters or regex patterns will return true:
isGlob('!foo.js', {strict: false});
isGlob('*.js', {strict: false});
isGlob('**/abc.js', {strict: false});
isGlob('abc/*.js', {strict: false});
isGlob('abc/(aaa|bbb).js', {strict: false});
isGlob('abc/[a-z].js', {strict: false});
isGlob('abc/{a,b}.js', {strict: false});
//=> true
Extglobs
isGlob('abc/@(a).js', {strict: false});
isGlob('abc/!(a).js', {strict: false});
isGlob('abc/+(a).js', {strict: false});
isGlob('abc/*(a).js', {strict: false});
isGlob('abc/?(a).js', {strict: false});
//=> true
False
Escaped globs or extglobs return false:
isGlob('\\!foo.js', {strict: false});
isGlob('\\*.js', {strict: false});
isGlob('\\*\\*/abc.js', {strict: false});
isGlob('abc/\\*.js', {strict: false});
isGlob('abc/\\(aaa|bbb).js', {strict: false});
isGlob('abc/\\[a-z].js', {strict: false});
isGlob('abc/\\{a,b}.js', {strict: false});
