teeny-conf

A small npm package to handle one or multiple config files in Node apps. Works well with Electron and NW.js.

All I/O operations are synchronous and write operation are atomic to avoid files corruption.

Saving and reloading are manual, in case you have to handle large files and avoid useless I/O operations.

Why another ?

I didn't find what I wanted on npm, I was needing a conf I could put in a variable, so I could export it without any problem to another scope.

Installation

npm install teeny-conf

Usage

Basic

config.js:

import teeny from 'teeny-conf';

const config = new teeny('config.json'));

conf.set('language', 'en');
conf.save(); // Save is a manual operation

Nested keys

config.js:

import teeny from 'teeny-conf';

const config = new teeny('config.json', {
  some: {
    nested: {
      property: 42
    }
  }
}));

conf.get('some.nested.property'); // -> 42

Using an export

config.js:

import teeny from 'teeny-conf';

const config = new teeny('config.json'));

export default config;

main.js

import config from './config.js';
// now you can use config.set(), config.get(), etc...
