memento-vuex

A minimalist Vuex plugin for persistent data storage.

Installation

With Yarn:

yarn add memento-vuex

With NPM:

npm install memento-vuex

Usage

import Vuex from "vuex"
import Memento from "memento-vuex"

export default Vuex.createStore({
	state: {
		colour:  "red",
		size:    "big",
		visible: true,
	}

	plugins: [
		Memento(
			// Mutations to watch and attributes to back up
			{
				setColour: "colour",
				setSize:   "size",
				// state.visible won't be backed up
			},
			// A name under which the backup is stored in localStorage
			// It's "vuex" by default, but it's recommended to set it to something meaningful
			"memento-example",
			// The name of a mutation that copies data to state
			// It's "import" by default, but you may change it
			"import"
		)
	],

	mutations: {
		setColour(state, colour) {
			state.colour = colour
		},

		setSize(state, size) {
			state.size = size
		},

		toggleVisible(state) {
			state.visible = !state.visible
		},

		// You have to have a mutation that copies data to state
		// This is one of the shortest implementations
		import(state, backup) {
			Object.assign(state, backup)
		},
	},
}
