Simple Key/Value storage atop chrome.storage. For Chrome extensions.

Default chrome.storage api is a pain to deal with when it comes to things like updating or removing specific values in hashes, since you can only save or load a whole hash at a time.

I believe this is by design as the use-case it was designed for was probably simply saving and loading a user's settings for an extension. This is fine for most use-cases, but if you are programmatically storing a collection of items that changes over time, then this lib should prove more convenient.

$ component install timoxley/chrome-keyvalue

var assert = require('assert')
var KeyValue = require('chrome-keyvalue')

// create a new instance for 'users'
var kv = new KeyValue('users')

kv.set('tim', { // save a user
	name: 'Tim',
	age: 27
}, function(err, val) {
	assert.ifError(err)
	assert.equal(val.name, 'Tim')

	// get the record we just saved
	kv.get('tim', function(err, val) {
		assert.ifError(err)
		assert.equal(val.name, 'Tim')
		assert.equal(val.age, 27)
		done()
	})
})

• KeyValue.useLocal()
• KeyValue.useSync()
• KeyValue.get()
• KeyValue.del()
• KeyValue.clear()

KeyValue constructor. Give it a unique name.

Use chrome.storage.local instead of chrome.storage.sync.

chrome.storage.local doesn't sync data to this account on other machines.

Use chrome.storage.sync instead of chrome.storage.local. chrome.storage.sync is the default and this method only exists for completeness.
