# configstore [](https://travis-ci.org/yeoman/configstore)
> Easily load and persist config without having to think about where and how
The config is stored in a JSON file located in `$XDG_CONFIG_HOME` or `~/.config`.
Example: `~/.config/configstore/some-id.json`
*If you need this for Electron, check out [`electron-store`](https://github.com/sindresorhus/electron-store) instead.*
*And check out [`conf`](https://github.com/sindresorhus/conf) for an updated approach to this concept.*
## Install
```
$ npm install configstore
```
## Usage
```js
const Configstore = require('configstore');
const packageJson = require('./package.json');
// Create a Configstore instance
const config = new Configstore(packageJson.name, {foo: 'bar'});
console.log(config.get('foo'));
//=> 'bar'
config.set('awesome', true);
console.log(config.get('awesome'));
//=> true
// Use dot-notation to access nested properties
config.set('bar.baz', true);
console.log(config.get('bar'));
//=> {baz: true}
config.delete('awesome');
console.log(config.get('awesome'));
//=> undefined
```
## API
### Configstore(packageName, defaults?, options?)
Returns a new instance.
#### packageName
Type: `string`
Name of your package.
#### defaults
Type: `object`
Default config.
#### options
Type: `object`
##### globalConfigPath
Type: `boolean`
Default: `false`
Store the config at `$CONFIG/package-name/config.json` instead of the default `$CONFIG/configstore/package-name.json`. This is not recommended as you might end up conflicting with other tools, rendering the "without having to think" idea moot.
##### configPath
Type: `string`
Default: Automatic
**Please don't use this option unless absolutely necessary and you know what you're doing.**
Set the path of the config file. Overrides the `packageName` and `globalConfigPath` options.
### Instance
You can use [dot-notation](https://github.com/sindresorhus/dot-prop) in a `key` to access nested properties.
### .set(key, value)
Set an item.
### .set(object)
Set multiple items at once.
### .get(key)
Get an item.
### .has(key)
Check if an item exists.
### .delete(key)
Delete an item.
### .clear()
Delete all items.
### .size
Get the item count.
### .path
Get the path to the config file. Can be used to show the user where the config file is located or even better open it for them.
### .all
Get all the config as an object or replace the current config with an object:
```js
config.all = {
hello: 'world'
};
```
