tiny-namespace

Set and get data on a namespace singleton without using global scope at all.

Install

npm install --save tiny-namespace

Methods

set(path, data)

Used to set data on a given namespace. Returns updated namespace.

Usage:

const ns = require('tiny-namespace')
ns.set('space.planets.earth', 'yeah!')

Will create or extend an existing namespace.

get(path)

Will return existing data on the requested path or undefined if the path doesn't exist.

Usage:

const ns = require('tiny-namespace')
const value = ns.get('space.planets.earth')

has(path)

Returns true if passed path exists. False otherwise.

Usage:

const ns = require('tiny-namespace')
if (ns.has('space.planets')) {
  // Do something if there are planets.
}

Examples

const ns = require('tiny-namespace')
const namespace = ns.set('space.planets.earth', {
  animals: ['dolphins', 'dogs', 'cats']
})

namespace will equal:

{
  space: {
    planets: {
      earth: {
        animals: ['dolphins', 'dogs', 'cats']
      }
    }
  }
}

You can later do, on another file:

const ns = require('tiny-namespace')
const earthAnimals = ns.get('space.planets.earth.animals')

earthAnimals will equal:

['dolphins', 'dogs', 'cats']

And if you ask: ns.has('space.planets.earth.animals')

It will return true.

Namespace access

Normally you would use ns.get, but there's also a special property that holds a reference to the whole namespace: ns.$

Let's say you add stuff to your namespace, like:

const ns = require('tiny-namespace')
ns.set('space.planets.earth', 'cool')
ns.set('music.tango', 'nice')
ns.set('hi', 'there')

You can later access ns.$ and you'll get:

{
  space: {
    planets: {
      earth: 'cool'
    }
  },
  music: {
    tango: 'nice'
  },
  hi: 'there'
}
