A [Node](https://nodejs.org/) module to check if a 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 npm.](https://docs.npmjs.com/cli/install)
```
npm install is-resolvable
```
## API
```javascript
const isResolvable = require('is-resolvable');
```
### isResolvable(*moduleId*)
*moduleId*: `String` (module ID)
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 `lodash` module is installed but `underscore` isn't
isResolvable('lodash'); //=> true
isResolvable('underscore'); //=> false
// When `readable-stream` module is installed
isResolvable('readable-stream/readable'); //=> true
isResolvable('readable-stream/writable'); //=> true
```
