Package description

What is anymatch?

The anymatch npm package is a utility that allows you to match strings against a variety of patterns including strings, regexes, and functions. It is commonly used to test whether a given string matches any of a set of criteria, which is useful for tasks like filtering file paths or determining if an event should trigger a particular action.

What are anymatch's main functionalities?

String pattern matching

Match a string against a single glob pattern.


Array of patterns matching

Match a string against an array of glob patterns.

anymatch(['*.js', '*.css'], 'foo.js')

Function as a custom matcher

Use a function as a custom matcher in the array of patterns.

anymatch([/\.js$/, (string) => string.includes('foo')], 'foo.js')

Negated patterns

Use negated patterns to exclude matches.

anymatch(['*.js', '!foo.js'], 'foo.js')

Partial application

Create a partially applied matcher function for reuse.

const isJsFile = anymatch('*.js');

anymatch Build Status Coverage Status

Javascript module to match a string against a regular expression, glob, string, or function that takes the string as an argument and returns a truthy or falsy value. The matcher can also be an array of any or all of these. Useful for allowing a very flexible user-defined config to define things like file paths.

Note: This module has Bash-parity, please be aware that Windows-style backslashes are not supported as separators. See for more information.


npm install anymatch
anymatch(matchers, testString, [returnIndex], [options])
  • matchers: (Array|String|RegExp|Function) String to be directly matched, string with glob patterns, regular expression test, function that takes the testString as an argument and returns a truthy value if it should be matched, or an array of any number and mix of these types.
  • testString: (String|Array) The string to test against the matchers. If passed as an array, the first element of the array will be used as the testString for non-function matchers, while the entire array will be applied as the arguments for function matchers.
  • options: (Object [optional]_) Any of the picomatch options.
    • returnIndex: (Boolean [optional]) If true, return the array index of the first matcher that that testString matched, or -1 if no match, instead of a boolean result.
const anymatch = require('anymatch');

const matchers = [ 'path/to/file.js', 'path/anyjs/**/*.js', /foo.js$/, string => string.includes('bar') && string.length > 10 ] ;

anymatch(matchers, 'path/to/file.js'); // true
anymatch(matchers, 'path/anyjs/baz.js'); // true
anymatch(matchers, 'path/to/foo.js'); // true
anymatch(matchers, 'path/to/bar.js'); // true
anymatch(matchers, 'bar.js'); // false

// returnIndex = true
anymatch(matchers, 'foo.js', {returnIndex: true}); // 2
anymatch(matchers, 'path/anyjs/foo.js', {returnIndex: true}); // 1

// any picomatc

// using globs to match directories and their children
anymatch('node_modules', 'node_modules'); // true
anymatch('node_modules', 'node_modules/somelib/index.js'); // false
anymatch('node_modules/**', 'node_modules/somelib/index.js'); // true
anymatch('node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // false
anymatch('**/node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // true

const matcher = anymatch(matchers);
['foo.js', 'bar.js'].filter(matcher);  // [ 'foo.js' ]
anymatch master* ❯


You can also pass in only your matcher(s) to get a curried function that has already been bound to the provided matching criteria. This can be used as an Array#filter callback.

var matcher = anymatch(matchers);

matcher('path/to/file.js'); // true
matcher('path/anyjs/baz.js', true); // 1

['foo.js', 'bar.js'].filter(matcher); // ['foo.js']
