vuex-dry

vuex-dry helps keep your vuex code DRY. It doesn't introduce any whole new way to use vuex. It just helps build modules for you with a minimum amount of code, adding some convenient getters, mutations, and actions.

vuex-dry is TypeScript-friendly since it's written in TypeScript.

Install

npm i vuex-dry -S

Add the plugin to your vuex store.

import { plugin } from "vuex-dry";

new Vuex.Store({
  plugins: [plugin],
  ...
});

Getting Started

Simple Module

import { Module } from "vuex-dry";

const user = Module.build({
  state() {
    return {
      name: undefined
    };
  }
});

const store = new Vuex.Store({
  modules: {
    user
  }
});

That's it. At Module.build(), we put a function named state returning an object. This object will be used as an initial state and also used when you want to reset a specific state or even whole state. We'll see how to reset things later.

Let's look at the module building part again.

Module.build({
  state() {
    return {
      name: undefined
    };
  }
});

The code above is effectively same as the following:

{
  namespaced: true,
  state {
    name: undefined
  },
  getters: {
    name: state => state.name
  },
  mutations: {
    name$assign(state, value) {
      state.name = value;
    },
    name$reset(state) {
      state.name = undefined;
    },
    $resetAll(state) {
      state.name = undefined;
      // also resetting other states if exists
    }
  },
  actions: {
    name$assign({ commit }, value) {
      commit("name$assign", value);
    },
    name$reset({ commit }) {
      commit("name$reset");
    },
    $resetAll({ commit }) {
      commit("$resetAll");
    }
  }
})

You see what has been done here?

The followings are added to your module:

  • A getter name
  • A mutation and an action name$assign to set a value to the state name.
  • A mutation and an action name$reset to reset the state name.
  • A mutation and an action $resetAll to reset all states from the module.

These are always repeated every time we write vuex code. And now you don't need them anymore.

Interested?

Let me show you how easy you can access/handle arrays and objects with vuex-dry.

And you will see how to map those getters in your component and you even can map a specific nested property of an object.

So, why vuex-dry?

It keeps your code DRY. You don't have to write meaningless similar codes over and over again.

Then why not vuex-pathify?

vuex-pathify is a great library. It let you do things without any coding but just with conventions. A downside is it introduces its own conventions and once you get started with it, you're in a whole new thing. On some level, you're using vuex through APIs of vuex-pathify, but on the outside you actually are not using vuex anymore.

On the other hand, vuex-dry just simply creates vuex modules and they are completely compatible with your existing vuex store and modules. And since it's creating pure vuex modules, you can extend it as you want. It's highly customizable. In that sense, it's really easy to introduce vuex-dry into your current project and you don't even have to replace all your vuex codes with vuex-dry. You can partially adjust vuex-dry and there's no problem with that.
