Getting properties

Simple names

Property name: product / component / property
Getter method: reconf('product.component.property')

Dashed names

Property name: some-product / some-component / some-property
Getter method: reconf('some-product.some-component.some-property')
Getter method: reconf('some-product[some-component][some-property]')

Doted name

Property name: some.product / some.component / some.property
Getter method: reconf('some-product[some-component][some-property]')

Setting properties

Saving strings

Property name: product / component / property
Setter method: reconf('product.component.property', 'Hello world!')

Saving numbers

Property name: product / component / property
Setter method: reconf('product.component.property', 42)

Saving objects

Property name: product / component / property
Setter method: reconf('product.component.property', { foo : 'bar' })

Simple usage

let reconf = require('reconf-nodejs');

reconf('product.component.property')
    .then(propValues => {
        console.log(propValues); // All values in array
    })
    .catch(err => {
        console.log(err); // Some error
    });

Using on multiple files

When using on multiple "requires", you'll need setup ReConf just one time. The module will handle how to share the methods by yourself.

// config.js

let {setup} = require('reconf-nodejs');

setup({
    protocol: 'https', // default is "http"
    host: 'config-reader.reconf.url',
    product: {
        'product': {
            'component': {
                'property': 'Initial Value' // Can be "undefined"
            }
        }
    },
    applicationUser: 'reconfUserApplication'
});

// file_that_use_props.js

let reconf = require('reconf-nodejs');

reconf('product.component.property').then(propValue => console.log(propValue));
