![]() ![]() For example, when a new calculation is evaluated on a calculator, you’d want the total to be updated. Now that we can get data from the state, we need a way to change or modify it. The getters are just functions that get the data from the state for you. We can retrieve data from the store by defining the getters of the store and then calling them when we need to. The state is the JavaScript object that contains the actual data that your app needs to function. The first thing our store needs is the state. The store is a global object that contains four major things that Vuex needs to manage state in our Vue app. In Vuex, you have something called the store. A simple overview of Vuex and its most important concepts are critical to be familiar with as it will make building this app (and future ones) much easier. The whole idea behind Vuex is confusing at first but becomes clear with time. This pulls in our styles from styles.css and imports the following three JavaScript files:Īt this point, your project folder should look like this: Setting up Vue and VuexĬreate a folder to serve as the root directory for this app, and create three files in that folder, index.html to contain our markup, styles.css for our styles, and app.js for our code. It offers you a clear and organized way to initialize, manage, and modify your Vue application’s state in a straightforward and easy-to-track way. For example, if you open a calculator app for the first time, its current total would be 0 so its state could look like this:Īfter you evaluate 2 + 4, its state could look like this: The state of an application is a collection of variables and their values at that point in time (basically the data powering your app). You can get away without standalone state management if your app is small, but as it grows, your code could easily become a nightmare to debug and iterate upon. State ManagementĪs mentioned before, state management becomes tricky when your app becomes larger and more complex. You can check out a live demo of the finished app here. Make sure that you are comfortable with both JavaScript and Vue before continuing with this tutorial. In this tutorial, we will be diving into Vuex by building a nice todo app. The Vue team, realizing that their library would also need a way to manage state, introduced Vuex, the official state management library for Vue. Facebook’s answer to this challenge was Flux, a pattern that later served as the basis for the more popular Redux state management library that is commonly used with React. However, despite these advantages, one issue that eventually hits any application that grows large enough is the difficulty of managing its state. Components allow you to easily reuse code, reduce architectural complexity, and build impressive user interfaces by logically dividing your code into independent chunks. Breaking down larger pieces of an app into smaller components has become really popular thanks to the rise of front-end libraries like React and Vue. ![]()
