A [Node.js](https://nodejs.org/) module to check if a given module ID is resolvable with [`require()`](https://nodejs.org/api/globals.html#globals_require)

```javascript
const isResolvable = require('is-resolvable');

isResolvable('fs'); //=> true
isResolvable('path'); //=> true

// When ./index.js exists
isResolvable('./index.js') //=> true
isResolvable('./index') //=> true
isResolvable('.') //=> true
```

## Installation

[Use](https://docs.npmjs.com/cli/install) [npm](https://docs.npmjs.com/getting-started/what-is-npm).

```
npm install is-resolvable
```

## API

```javascript
const isResolvable = require('is-resolvable');
```

### isResolvable(*moduleId* [, *options*])

*moduleId*: `string` (module ID)  
*options*: `Object` ([`require.resolve`](https://nodejs.org/api/modules.html#modules_require_resolve_request_options) options)  
Return: `boolean`

It returns `true` if `require()` can load a file form a given module ID, otherwise `false`.

```javascript
const isResolvable = require('is-resolvable');

// When ./foo.json exists
isResolvable('./foo.json'); //=> true
isResolvable('./foo'); //=> true

isResolvable('./foo.js'); //=> false

// When `eslint` module is installed but `jshint` isn't
isResolvable('eslint'); //=> true
isResolvable('jshint'); //=> false

// When `lodash` module is installed
isResolvable('lodash/isObject'); //=> true
isResolvable('lodash/fp/reject.js'); //=> true
```

The second argument accepts an options object for `require.resolve()`.

```javascript
// When ./bar/baz.js exists

isResolvable('./baz.js'); //=> false
isResolvable('./baz.js', {paths: ['bar']}); //=> true
```
