Cross-platform config file management made easy. Works great with command-line tools and Electron apps.
When building command-line tools and desktop apps with Node.js, there exists a common need for managing application configuration files.
xcfg is a package that saves you the trouble of validating config paths across multiple platforms and creating the config file. It makes config file management easy by handling all IO operations under the hood, and provides a simple
set() interface for individual configuration properties. JSON is used as the config file format to be easy on both machines and humans (and to eliminate the need for 3rd party dependencies).
$ cd node-project$ npm install xcfg
Require the module and create a new instance:
var Xcfg = require('xcfg')var xcfg = new Xcfg('net.jonbeebe.myapp')
On construction, after sanitizing the
id, it is used to create a configuration file (if it doesn't already exist) at the following path:
After that, you can use the
xcfg instance to get, set, and delete properties on the in-memory object:
xcfg.set('foo', 'bar')xcfg.get('foo') // barxcfg.del('foo')xcfg.get('foo') // undefined
The above will only manipulate the in-memory config instance. To persist changes to disk, use
And while there's a little more to it than that, that's the basic idea and really all you need to know to use this package. To see more methods and options, view the documentation.
