This package provides Electron developers with a simple, consistent interface for managing user preferences. It includes two primary components:
- A GUI interface within which the users of your application can manage their preferences.
- An API for interacting with the service.
Using the API, developers can:
- Define default preferences
- Read / write values on demand
- Define the layout of the preferences window.
To see the library in action, clone this repository and see the demo application that is included within the example folder:
$ git clone https://github.com/tkambler/electron-preferences.git
$ cd electron-preferences
$ npm i
$ npm run build
$ npm run example
$ npm run lint
Within your application's main process, create a new instance of the ElectronPreferences class, as shown below.
Please keep in mind that not all available components are used here. For an example usage of them, check out example/preferences.js
const electron = require('electron');
const app = electron.app;
const path = require('path');
const os = require('os');
const ElectronPreferences = require('electron-preferences');
// import ElectronPreferences from 'electron-preferences' //Or if you prefer to use module imports
const preferences = new ElectronPreferences({
/**
* Where should preferences be saved?
*/

You prefer a dark theme over a light theme? No problem, we have them both. The library will use whatever theme you're using with Electron. See the example on how to add the option to your preferences.
Still not matching your layout? You can easily customize the complete look by injecting your own custom CSS!
The library includes built-in support for the following field types:
- Text
- Dropdown
- Message
- Folder/File selection
- Checkbox
- Radio
- Slider
- (Ordered) Lists
- Accelerator (for shortcut input)
- Color picker
Adding support for additional field types if easy, if you're familiar with React. PR's for such additions are welcome.
The following icons come packaged with the library and can be specified when you define the layout of your preferences window.
