vue-mini-state 🔮

vue-mini-state is a simple state management lib for Vuejs. It uses the Observable object. It's intended to be very simplistic and easy to use. What's the best of it ? It's centralized! Thus, you can use it at different components without worrying about drilling down any prop.

vue-mini-state uses object manipulations in order to merge multiple paths inside the state.

Motivation

State Management is something that always lead you to use a complex third-party library or is either something complex to build from scratch. vue-mini-state is intended to be used still as a third party library but it is extremely small and it uses Vue js native Observable, which in my opinion is very good and should be used more broadly.

I needed to find a way to create a state management that could be used easily inside the directive v-for and inside the HTML templates. As a result, I created this lightweight lib that might be useful for you as it's being useful for me in my Vue projects.

API

• getState() Returns the entire state.

• getState(path) Returns the value of the path inside the state.

• setState(data) Makes the data object to be the entire state. It will be set at the root.

• setState(data, path) Updates the state at the specified path.

• resetState() Resets the entire state to its initial value.

Getting Started

$ npm install vue-mini-state

How does it work

vue-mini-state relies on strings that represent the paths that will be used inside the state. For example: The path customer.street.number represents the path to an object that looks like this:

const state = {
  "customer": {
    "street": {
      "number": 5 // any value here
    }
  }
}

You can either select if you want to save the change to the root or if you want to nest it under a specific property

import { getState, setState } from 'vue-mini-state';

setState(16, 'customer.street.number');
setState({ name: 'Juan' }, 'customer');
getState('customer.street.number') // This will return 16;

/**
 * This will return
 *
 * {
 *   customer: {
 *     name: 'Juan',
 *     street: {
 *       number: 16
 *     }
 *   }
 * }
 */
getState();

IMPORTANT

As you can see, vue-mini-state works very well for scenarios in which you are going to populate multiple attributes of an object from different events/places. Moreover, it works assuming that you need the objects to be merged, not replaced.

Get Rid of the v-model

This sound a bit scary at the beggining, but the truth is that you can get rid of the v-model in your top level components and create easily a new Form with only path declarations. I will create a guide that explains to you how to use the vue-mini-state with a Web Components' library and allow you to create forms in a very fast way. Wait for it! :)
