Key/Json Store with multiple interfaces

• Install
• Example
• Managers
• API

To install key-json, simply use npm:

npm install key-json --save

const Kj = require('key-json')

const kj = Kj({
	loggerLevel: 'info'
})

kj
//default manager
.use(Kj.managers.redis({
	//redis createClient() configuration
	host: '127.0.0.1',
	port: 6379
}))
.use('memcached', Kj.managers.memcached('localhost:11211', {
	retries:10,
	retry:10000,
	remove:true,
}))
.set('foo', { foo: 'foo' }, (err) => {
})
.get('foo', (err, json) => {
})
.has('foo', (err, exists) => {
})
.delete('foo', (err, done) => {
})
.manager('memcached')
//set bar key in the memcached manager
.set('bar', { bar: 'bar' }, (err) => {
})

A Manager is an abstraction layer between key-json and storage systems. Currently there are two available managers

• Redis
• Memcached

• Kj()
• instance.use()
• instance.manager()
• instance.set()
• instance.get()
• instance.has()
• instance.delete()

Creates a new instance of KeyJson.

Options are:

• loggerLevel: ['info', 'warn', 'error', 'fatal']

Set a new manager configuration

• key, unique key for the manager
• manager, compatible manager interface

Switch to another manager by its key

• key, unique key for the manager

Store json in its key/value store

• expiry -> TTL for this key in seconds
• cb -> (error) => {}

Get json by its key

• cb -> (err, json) => {}, json is already parsed

Check if key is stored

• cb -> (err, exists) => {}, exists is a boolean

Delete key from the store

• cb -> (err, done) => {}, done is a boolean
