# multimatch [](https://travis-ci.org/sindresorhus/multimatch)
|
||
|
||
> Extends [`minimatch.match()`](https://github.com/isaacs/minimatch#minimatchmatchlist-pattern-options) with support for multiple patterns
|
||
|
||
|
||
## Install
|
||
|
||
```sh
|
||
|
||
$ npm install --save multimatch
|
||
```
|
||
|
||
|
||
## Usage
|
||
|
||
```js
|
||
var multimatch = require('multimatch');
|
||
|
||
multimatch(['unicorn', 'cake', 'rainbows'], ['*', '!cake']);
|
||
//=> ['unicorn', 'rainbows']
|
||
```
|
||
|
||
See the [tests](https://github.com/sindresorhus/multimatch/blob/master/test.js) for more usage examples and expected matches.
|
||
|
||
|
||
## API
|
||
|
||
Same as [`minimatch.match()`](https://github.com/isaacs/minimatch#minimatchmatchlist-pattern-options) except for `pattern` also accepting an array.
|
||
|
||
```js
|
||
var results = multimatch(paths, patterns);
|
||
```
|
||
|
||
The return value is an array of matching paths.
|
||
|
||
|
||
## How multiple patterns work
|
||
|
||
Positive patterns (e.g. `foo` or `*`) add to the results, while negative patterns (e.g. `!foo`) subtract from the results.
|
||
|
||
Therefore a lone negation (e.g. `['!foo']`) will never match anything – use `['*', '!foo']` instead.
|
||
|
||
|
||
## 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

See [globby](https://github.com/sindresorhus/globby) if you need to match against the filesystem instead of a list.
