Create a Store

Initial Store

Invoke nestore with an object with any keys/values to setup the initial state.

myStore.js

import nestore from 'nestore'

const nst = nestore({ 
    logged_in: false,
    user_name: null,
    time: Date.now(),
    1: 'Two',
})

export default nst

Mutators

You can also register 'in-store' mutators to keep logic and state in a central location.

const nst = nestore({
    error: null, 
    logged_in: false,
    user_name: null,
    time: Date.now(),

    getTime:    () => Date.now(),
    setTime:    (NST) => NST.set('time', Date.now()),
    customTime: (NST, args) => NST.set('time', args[0]),
    
    login: async (NST, [name, pwrd]) => {
        let user = await Users.findOne({ where: { user_name: name }})

        if(!user){
            NST.set('error', 'No user found...')
            return false
        }

        NST.store.user_name = user.user_name
        NST.store.logged_in = true

        return user
    }

})

Nestore will expose these functions for use outside the store

import nst from  './myStore.js'

const user = await nst.login('AliceAware11', 'password1234')
// await nst.login('AliceAware11', 'password1234')
// nst.login('AliceAware11', 'password1234')

Listeners

Listeners can also be registered directly in the store with the $ prefix. All listeners are invoked with an object containing the path and key of the value that changed, as well as the new value.

const nst = nestore({
    logged_in: false,
    user_name: null,

    login: async (NST, [name, pwrd]) => {
        // ...
    },

    $user_name: ({ value }) => {
        console.log(`The user ${value} has logged in!`)
    },

})
