# globby [](https://travis-ci.org/sindresorhus/globby)
|
|
|
|
> User-friendly glob matching
|
|
|
|
Based on [`fast-glob`](https://github.com/mrmlnc/fast-glob), but adds a bunch of useful features and a nicer API.
|
|
|
|
|
|
## Features
|
|
|
|
- Promise API
|
|
- Multiple patterns
|
|
- Negated patterns: `['foo*', '!foobar']`
|
|
- Expands directories: `dir` → `dir/**/*`
|
|
- Supports `.gitignore`
|
|
|
|
|
|
## Install
|
|
|
|
```
|
|
$ npm install globby
|
|
```
|
|
|
|
|
|
## Usage
|
|
|
|
```
|
|
├── unicorn
|
|
├── cake
|
|
└── rainbow
|
|
```
|
|
|
|
```js
|
|
const globby = require('globby');
|
|
|
|
(async () => {
|
|
const paths = await globby(['*', '!cake']);
|
|
|
|
console.log(paths);
|
|
//=> ['unicorn', 'rainbow']
|
|
})();
|
|
```
|
|
|
|
|
|
## API
|
|
|
|
### globby(patterns, [options])
|
|
|
|
Returns a `Promise<Array>` of matching paths.
|
|
|
|
#### patterns
|
|
|
|
Type: `string` `Array`
|
|
|
|
See supported `minimatch` [patterns](https://github.com/isaacs/minimatch#usage).
|
|
|
|
#### options
|
|
|
|
Type: `Object`
|
|
|
|
See the [`fast-glob` options](https://github.com/mrmlnc/fast-glob#options) in addition to the ones below.
|
|
|
|
##### expandDirectories
|
|
|
|
Type: `boolean` `Array` `Object`<br>
|
|
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:
|
|
|
|
```js
|
|
(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 `nodir: false`.
|
|
|
|
##### gitignore
|
|
|
|
Type: `boolean`<br>
|
|
Default: `false`
|
|
|
|
Respect ignore patterns in `.gitignore` files that apply to the globbed files.
|
|
|
|
### globby.sync(patterns, [options])
|
|
|
|
Returns an `Array` of matching paths.
|
|
|
|
### globby.generateGlobTasks(patterns, [options])
|
|
|
|
Returns an `Array<Object>` in the format `{pattern: string, opts: Object}`, which can be passed as arguments to [`fast-glob`](https://github.com/mrmlnc/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`](https://github.com/isaacs/node-glob#globhasmagicpattern-options)
|
|
|
|
### 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.
|
|
|
|
```js
|
|
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
|
