globby Build Status

User-friendly glob matching

Based on fast-glob, but adds a bunch of useful features and a nicer API.

Features

  • Promise API
  • Multiple patterns
  • Negated patterns: ['foo*', '!foobar']
  • Expands directories: dirdir/**/*
  • Supports .gitignore

Install

$ npm install globby

Usage

├── unicorn
├── cake
└── rainbow
const globby = require('globby');

(async () => {
	const paths = await globby(['*', '!cake']);

	console.log(paths);
	//=> ['unicorn', 'rainbow']
})();

API

Note that glob patterns can only contain forward-slashes, not backward-slashes, so if you want to construct a glob pattern from path components, you need to use path.posix.join() instead of path.join().

globby(patterns, options?)

Returns a Promise<string[]> of matching paths.

patterns

Type: string | string[]

See supported minimatch patterns.

options

Type: object

See the fast-glob options in addition to the ones below.

expandDirectories

Type: boolean | string[] | object
Default: true

If set to true, globby will automatically glob directories for you. If you define an Array it will only glob files that matches the patterns inside the Array. You can also define an object with files and extensions like below:

const globby = require('globby');

(async () => {
	const paths = await globby('images', {
		expandDirectories: {
			files: ['cat', 'unicorn', '*.jpg'],
			extensions: ['png']
		}
	});

	console.log(paths);
	//=> ['cat.png', 'unicorn.png', 'cow.jpg', 'rainbow.jpg']
})();

Note that if you set this option to false, you won't get back matched directories unless you set onlyFiles: false.

gitignore

Type: boolean
Default: false

Respect ignore patterns in .gitignore files that apply to the globbed files.

globby.sync(patterns, options?)

Returns string[] of matching paths.

globby.stream(patterns, options?)

Returns a stream.Readable of matching paths.

Since Node.js 10, readable streams are iterable, so you can loop over glob matches in a for await...of loop like this:

const globby = require('globby');

(async () => {
	for await (const path of globby.stream('*.tmp')) {
		console.log(path);
	}
})();

globby.generateGlobTasks(patterns, options?)

Returns an object[] in the format {pattern: string, options: Object}, which can be passed as arguments to fast-glob. This is useful for other globbing-related packages.

Note that you should avoid running the same tasks multiple times as they contain a file system cache. Instead, run this method each time to ensure file system changes are taken into consideration.

globby.hasMagic(patterns, options?)

Returns a boolean of whether there are any special glob characters in the patterns.

Note that the options affect the results. If noext: true is set, then +(a|b) will not be considered a magic pattern. If the pattern has a brace expansion, like a/{b/c,x/y}, then that is considered magical, unless nobrace: true is set.

This function is backed by node-glob

globby.gitignore(options?)

Returns a Promise<(path: string) => boolean> indicating whether a given path is ignored via a .gitignore file.

Takes cwd?: string and ignore?: string[] as options. .gitignore files matched by the ignore config are not used for the resulting filter function.

const {gitignore} = require('globby');

(async () => {
	const isIgnored = await gitignore();
	console.log(isIgnored('some/file'));
})();

globby.gitignore.sync(options?)

Returns a (path: string) => boolean indicating whether a given path is ignored via a .gitignore file.

Takes the same options as globby.gitignore.

Globbing patterns

Just a quick overview.

  • * matches any number of characters, but not /
  • ? matches a single character, but not /
  • ** matches any number of characters, including /, as long as it's the only thing in a path part
  • {} allows for a comma-separated list of "or" expressions
  • ! at the beginning of a pattern will negate the match

Various patterns and expected matches.
