# 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`.<br>
|
||
|
|
Example: `~/.config/configstore/some-id.json`
|
||
|
|
|
||
|
|
*If you need this for Electron, check out [`electron-store`](https://github.com/sindresorhus/electron-store) instead.*<br>
|
||
|
|
*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`<br>
|
||
|
|
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`<br>
|
||
|
|
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.
|
||
|
|
|
||

|
|
|

|
||
|
|
|
||
|
|
### .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'
|
||
|
|
};
|
||
|
|
```
