## Install

```

## API

### [detectInstalled](index.js#L60)
> Detect if some package `name`is installed globally or locally. By default checks if it exists in globally installed modules, using [global-modules][]. Pass `opts.local` to check if it exists in locally installed modules or in `opts.cwd` dir.

**Params**

* `name` **{String}**: package name    
* `opts` **{Object}**: pass `opts.local` to check locally    
* `returns` **{Promise}**: always resolved promise, never rejected

**Example**

```js
const detectInstalled = require('detect-installed')

detectInstalled('npm').then((exists) => {
  console.log(exists) // => true
})

detectInstalled('foo-bar-barwerwlekrjw').then((exists) => {
  console.log(exists) // => false
})

detectInstalled('npm', {
  local: true
}).then((exists) => {
  console.log(exists) // => false
})

detectInstalled('global-modules', {
  local: true
}).then((exists) => {
  console.log(exists) // => true
})

// If you are using it for some sub-directory
// pass `opts.cwd` to be where the `node_modules`
// folder is.
process.chidr('foo-bar-baz')
detectInstalled('global-modules', {
  local: true,
  cwd: '../'
}).then((exists) => console.log(exists)) // => true
```

### [.sync](index.js#L86)
> Synchronously check if package `name` exists as locally or globally installed modules.

**Params**

* `name` **{String}**: package name    
* `opts` **{Object}**: pass `opts.local` to check locally    
* `returns` **{Boolean}**: false, if error or not exists globally/locally

**Example**

```js
const detectInstalled = require('detect-installed')

const exists = detectInstalled.sync('npm') // => true
const result = detectInstalled.sync('global-modules', { local: true }) // => true
```

## Contributing
Pull requests and stars are always welcome. For bugs and feature requests, [please create an issue](https://github.com/tunnckoCore/detect-installed/issues/new).  
Please read the [contributing guidelines](CONTRIBUTING.md) for advice on opening issues, pull requests, and coding standards.  
If you need some help and can spent some cash, feel free to [contact me at CodeMentor.io](https://www.codementor.io/tunnckocore?utm_source=github&utm_medium=button&utm_term=tunnckocore&utm_campaign=github) too.

**In short:** If you want to contribute to that project, please follow these things

1. Please DO NOT edit [README.md](README.md), [CHANGELOG.md](CHANGELOG.md) and [.verb.md](.verb.md) files. See ["Building docs"](#building-docs) section.
2. Ensure anything is okey by installing the dependencies and run the tests. See ["Running tests"](#running-tests) section.
3. Always use `npm run commit` to commit changes instead of `git commit`, because it is interactive and user-friendly. It uses [commitizen][] behind the scenes, which follows Conventional Changelog idealogy.
4. Do NOT bump the version in package.json. For that we use `npm run release`, which is [standard-version][] and follows Conventional Changelog idealogy.

Thanks a lot! :)

## Building docs
Documentation and that readme is generated using [verb-generate-readme][], which is a [verb][] generator, so you need to install both of them and then run `verb` command like that

```
$ npm install verbose/verb#dev verb-generate-readme --global && verb
```

_Please don't edit the README directly. Any changes to the readme must be made in [.verb.md](.verb.md)._

## Running tests
Clone repository and run the following in that cloned directory

```
$ npm install && npm test
```
