Tiny localStorage wrapper (moved to https://github.com/ngoldman/tinystore)

tinystore.js

function TinyStore (name) {

    try {

      localStorage.setItem(name, JSON.stringify(this.session));
    }
    return this.session;
  };

  this.set = function (key, value) {

TinyStore

Useful for interacting with a persistent namespaced object store within localStorage without messing with anything else that might be there (like on *.github.io).

API

var store = new TinyStore('memories')

store.enabled
// -> true (you've got localStorage!)

store.get('saturday')
// -> undefined

store.set('saturday', 'karaoke')
// -> 'karaoke'

store.set('sunday', ['hangover', 'NaptimePDX'])
// -> ["hangover", "NaptimePDX"]

store.set('monday', { 'work': ['meetings', 'coding'] })
// -> { "work": ["meetings", "coding"] }

store.session
// -> { "saturday": "karaoke", "sunday": ["hangover", "NaptimePDX"], "monday": { "work": ["meetings", "coding"] } }

// you can manipulate the session object directly if that's your jam
store.session.whatever = { 'doge': 'sweater vests' }
store.save()
// -> { "saturday": "karaoke", "sunday": ["hangover", "NaptimePDX"], "monday": { "work": ["meetings", "coding"] }, "whatever": { "doge": "sweater vests" } }

store.remove('whatever')
// -> { "saturday": "karaoke", "sunday": ["hangover", "NaptimePDX"], "monday": { "work": ["meetings", "coding"] } }

store.clear()
// -> {}
