# :rocket: fast-glob

> Is a faster [`node-glob`](https://github.com/isaacs/node-glob) alternative.

## :bulb: Highlights

  * :rocket: Fast by using Streams and Promises. Used [readdir-enhanced](https://github.com/BigstickCarpet/readdir-enhanced) and [micromatch](https://github.com/jonschlinkert/micromatch).
  * :beginner: User-friendly, since it supports multiple and negated patterns (`['*', '!*.md']`).
  * :vertical_traffic_light: Rational, because it doesn't read excluded directories (`!**/node_modules/**`).
  * :gear: Universal, because it supports Synchronous, Promise and Stream API.
  * :money_with_wings: Economy, because it provides `fs.Stats` for matched path if you wanted.

## Install

```
$ npm install --save fast-glob
```

## Usage

#### Asynchronous

```js
const fg = require('fast-glob');

fg(['src/**/*.js', '!src/**/*.spec.js']).then((entries) => console.log(entries));
fg.async(['src/**/*.js', '!src/**/*.spec.js']).then((entries) => console.log(entries));
```

#### Synchronous

```js
const fg = require('fast-glob');

const entries = fg.sync(['src/**/*.js', '!src/**/*.spec.js']);
console.log(entries);
```

#### Stream

```js
const fg = require('fast-glob');

const stream = fg.stream(['src/**/*.js', '!src/**/*.spec.js']);

const entries = [];

stream.on('data', (entry) => entries.push(entry));
stream.once('error', console.log);
stream.once('end', () => console.log(entries));
```

## API

### fg(patterns, [options])
### fg.async(patterns, [options])

Returns a `Promise` with an array of matching [entries](#entry).

### fg.sync(patterns, [options])

Returns an array of matching [entries](#entry).

### fg.stream(patterns, [options])

Returns a [`ReadableStream`](https://nodejs.org/api/stream.html#stream_readable_streams) when the `data` event will be emitted with [`Entry`](#entry).

#### patterns

  * Type: `string|string[]`

This package does not respect the order of patterns. First, all the negative patterns are applied, and only then the positive patterns.

#### options

  * Type: `Object`

See [options](#options-1) section for more detailed information.

### fg.generateTasks(patterns, [options])

Return a set of tasks based on provided patterns. All tasks satisfy the `Task` interface:

```ts
interface Task {
  /**
   * Parent directory for all patterns inside this task.
   */
  base: string;
  /**
   * Dynamic or static patterns are in this task.
   */
  dynamic: boolean;
  /**
   * All patterns.
   */
  patterns: string[];
  /**
   * Only positive patterns.
   */
  positive: string[];
  /**
   * Only negative patterns without ! symbol.
   */
  negative: string[];
}
```

## Entry

The entry which can be a `string` if the [`stats`](#stats) option is disabled, otherwise `fs.Stats` with two additional `path` and `depth` properties.

## Options

#### cwd

  * Type: `string`
  * Default: `process.cwd()`

The current working directory in which to search.

#### deep

  * Type: `number|boolean`
  * Default: `true`

The deep option can be set to `true` to traverse the entire directory structure, or it can be set to a *number* to only traverse that many levels deep.

For example, you have the following tree:

```
test
└── one
    └── two
        └── index.js
```

> :book: If you specify a pattern with some base directory, this directory will not participate in the calculation of the depth of the found directories. Think of it as a `cwd` option.

```js
fg('test/**', { onlyFiles: false, deep: 0 });
// -> ['test/one']
fg('test/**', { onlyFiles: false, deep: 1 });
// -> ['test/one', 'test/one/two']

fg('**', { onlyFiles: false, cwd: 'test', deep: 0 });
// -> ['one']
fg('**', { onlyFiles: false, cwd: 'test', deep: 1 });
// -> ['one', 'one/two']
```

#### ignore

  * Type: `string[]`
  * Default: `[]`

An array of glob patterns to exclude matches.

#### dot

  * Type: `boolean`
  * Default: `false`

Allow patterns to match filenames starting with a period (files & directories), even if the pattern does not explicitly have a period in that spot.

#### stats

  * Type: `boolean`
  * Default: `false`

Return `fs.Stats` with two additional `path` and `depth` properties instead of a `string`.

#### onlyFiles

  * Type: `boolean`
  * Default: `true`

Return only files.

#### onlyDirectories

  * Type: `boolean`
  * Default: `false`

Return only directories.

#### followSymlinkedDirectories

  * Type: `boolean`
  * Default: `true`

Follow symlinked directories when expanding `**` patterns.

#### unique

  * Type: `boolean`
  * Default: `true`

Prevent duplicate results.

#### markDirectories

  * Type: `boolean`
  * Default: `false`

Add a `/` character to directory entries.

#### absolute

  * Type: `boolean`
  * Default: `false`

Return absolute paths for matched entries.

> :book: Note that you need to use this option if you want to use absolute negative patterns like `${__dirname}/*.md`.

#### nobrace

  * Type: `boolean`
  * Default: `false`

Disable expansion of brace patterns (`{a,b}`, `{1..3}`).

#### brace

  * Type: `boolean`
  * Default: `true`

The [`nobrace`](#nobrace) option without double-negation. This option has a higher priority then `nobrace`.

#### noglobstar

  * Type: `boolean`
  * Default: `false`

Disable matching with globstars (`**`).

#### globstar

  * Type: `boolean`
  * Default: `true`

The [`noglobstar`](#noglobstar) option without double-negation. This option has a higher priority then `noglobstar`.

#### noext

  * Type: `boolean`
  * Default: `false`

Disable extglob support (patterns like `+(a|b)`), so that extglobs are regarded as literal characters.

#### extension

  * Type: `boolean`
  * Default: `true`

The [`noext`](#noext) option without double-negation. This option has a higher priority then `noext`.

#### nocase

  * Type: `boolean`
  * Default: `false`

Disable a [case-sensitive](https://en.wikipedia.org/wiki/Case_sensitivity) mode for matching files.

##### Examples

* File System: `test/file.md`, `test/File.md`
* Case-sensitive for `test/file.*` pattern (`false`): `test/file.md`
* Case-insensitive for `test/file.*` pattern (`true`): `test/file.md`, `test/File.md`

#### case

  * Type: `boolean`
  * Default: `true`

The [`nocase`](#nocase) option without double-negation. This option has a higher priority then `nocase`.

#### matchBase

  * Type: `boolean`
  * Default: `false`

Allow glob patterns without slashes to match a file path based on its basename. For example, `a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.

#### transform

  * Type: `Function`
  * Default: `null`

Allows you to transform a path or `fs.Stats` object before sending to the array.

```js
const fg = require('fast-glob');

const entries1 = fg.sync(['**/*.scss']);
const entries2 = fg.sync(['**/*.scss'], { transform: (entry) => '_' + entry });

console.log(entries1); // ['a.scss', 'b.scss']
console.log(entries2); // ['_a.scss', '_b.scss']
```

If you are using **TypeScript**, you probably want to specify your own type of the returned array.

```ts
import * as fg from 'fast-glob';

interface IMyOwnEntry {
	path: string;
}

const entries: IMyOwnEntry[] = fg.sync<IMyOwnEntry>(['*.md'], {
	transform: (entry) => typeof entry === 'string' ? { path: entry } : { path: entry.path }
	// Will throw compilation error for non-IMyOwnEntry types (boolean, for example)
});
```

## How to exclude directory from reading?

You can use a negative pattern like this: `!**/node_modules` or `!**/node_modules/**`. Also you can use `ignore` option. Just look at the example below.

```
first/
├── file.md
└── second
    └── file.txt
```

If you don't want to read the `second` directory, you must write the following pattern: `!**/second` or `!**/second/**`.

```js
fg.sync(['**/*.md', '!**/second']); // ['first/file.txt']
fg.sync(['**/*.md'], { ignore: '**/second/**' }); // ['first/file.txt']
```

> :warning: When you write `!**/second/**/*` it means that the directory will be **read**, but all the entries will not be included in the results.

You have to understand that if you write the pattern to exclude directories, then the directory will not be read under any circumstances.

## How to use UNC path?

You cannot use UNC paths as patterns (due to syntax), but you can use them as `cwd` directory.

```ts
fg.sync('*', { cwd: '\\\\?\\C:\\Python27' /* or //?/C:/Python27 */ });
fg.sync('Python27/*', { cwd: '\\\\?\\C:\\' /* or //?/C:/ */ });
```

## Compatible with `node-glob`?

Not fully, because `fast-glob` does not implement all options of `node-glob`. See table below.

| node-glob    | fast-glob |
| :----------: | :-------: |
| `cwd`        | [`cwd`](#cwd) |
| `root`       | – |
| `dot`        | [`dot`](#dot) |
| `nomount`    | – |

| `nosort`     | – |
| `nounique`   | [`unique`](#unique) |
| `nobrace`    | [`nobrace`](#nobrace) or [`brace`](#brace) |
| `noglobstar` | [`noglobstar`](#noglobstar) or [`globstar`](#globstar) |
| `noext`      | [`noext`](#noext) or [`extension`](#extension) |
| `nocase`     | [`nocase`](#nocase) or [`case`](#case) |
| `matchBase`  | [`matchbase`](#matchbase) |
| `nodir`      | [`onlyFiles`](#onlyfiles) |
| `ignore`     | [`ignore`](#ignore) |
| `follow`     | [`followSymlinkedDirectories`](#followsymlinkeddirectories) |
