electron-vars

Share data among different processes in Electron.

You can use it in main or renderer process.

Usage

npm install --save electron-vars

// in main process
const vars = require('electron-vars');

// in renderer process
const vars = require('electron').remote.require('electron-vars');

vars.set('someKey', 'someValue');

const value = vars.get('someKey', 'defaultValue');

vars.unset('someKey');

Share functions

You can share methods too, but be aware that the methods will run in the process they are defined. For example:

// in renderer process A
vars.set('myMethod', () => { console.log('my method'); });
vars.get('myMethod')();

// in main process
vars.get('myMethod')();

// in renderer process B
vars.get('myMethod')();

You will find that 'my method' is printed 3 times in the console window of process A.

Persist data

vars.store('someKey', 'someValue');

const value = vars.retrieve('someKey', 'defaultValue');

const hasKey = vars.has('someKey');

vars.delete('someKey');

vars.clear();

Data will be stored in system default user config directory.
