## Differences with [cosmiconfig](https://github.com/davidtheclark/cosmiconfig)?
JoyCon is zero-dependency but feature-complete.
## Install
```bash
yarn add joycon
```
## Usage
```js
const JoyCon = require('joycon')
const joycon = new JoyCon()
joycon.load(['package-lock.json', 'yarn.lock'])
.then(result => {
// result is {} when files do not exist
// otherwise { path, data }
})
```
By default non-js files are parsed as JSON, if you want something different you can add a loader:
```js
const joycon = new JoyCon()
joycon.addLoader({
test: /\.toml$/,
load(filepath) {
return require('toml').parse(filepath)
}
})
joycon.load(['cargo.toml'])
```
## API
### constructor([options])
#### options
##### files
- Type: `string[]`
The files to search.
##### cwd
The directory to search files.
##### stopDir
The directory to stop searching.
##### packageKey
You can load config from certain property in a `package.json` file. For example, when you set `packageKey: 'babel'`, it will load the `babel` property in `package.json` instead of the entire data.
##### parseJSON
- Type: `(str: string) => any`
- Default: `JSON.parse`
The function used to parse JSON string.
### resolve([files], [cwd], [stopDir])
### resolve([options])
`files` defaults to `options.files`.
`cwd` defaults to `options.cwd`.
`stopDir` defaults to `options.stopDir` then `path.parse(cwd).root`.
If using a single object `options`, it will be the same as constructor options.
Search files and resolve the path of the file we found.
There's also `.resolveSync` method.
### load(...args)
The signature is the same as [resolve](#resolvefiles-cwd-stopdir).
Search files and resolve `{ path, data }` of the file we found.
There's also `.loadSync` method.
### addLoader(Loader)
```typescript
interface Loader {
name?: string
test: RegExp
load(filepath: string)?: Promise
loadSync(filepath: string)?: any
}
```
At least one of `load` and `loadSync` is required, depending on whether you're calling the synchonous methods or not.
### removeLoader(name)
Remove loaders by loader name.
### clearCache()
Each JoyCon instance uses its own cache.
