vuex module reuse

The customer form component PageCustomer.vue is responsible for displaying several form fields and error or success messages, when the user submits the form. We need two mutations for our customer form: ERROR, to set an error state when the request fails and SUCCESS for doing pretty much the opposite. We are now going to simplify in order to introduce Modularization, we will add the following code to index.js. This has the advantage of making it possible to reuse certain parts of the code and it also allows us to dynamically load Vuex modules as needed. Details. import Vue from 'nativescript-vue' import Vuex, {Module} from 'vuex' import counter from './modules/Counter2' import hgapi from './modules/HGAPIModule' Vue. Sometimes we may need to create multiple instances of a module, for example: Creating multiple stores that use the same module (e.g. # Module Reuse. This instructor-led, live training (online or onsite) is aimed at developers and programmers who wish to create, manage, and update Vue applications using Vuex. How to deploy Vue.js application to Firebase, How to Use Vuex and Vue-Router in a Vue.JS Project, MDB Vue : A Material Design Component for Vue Pro, Implement log monitoring with Seq and Serilog in .net Core, How to create project templates in .net core. Because I couldn’t find any examples of large scale applications using Vuex, which are open source, that would fit the needs of the project I was working on, I decided we can figure stuff out as I we were going. I am using vue, vuex & vue-router (v2.5, v3 & v3) The pattern I am currently using is to clone a model (basically a pojo) stored in a vuex module and pass it to a vue component housing various inputs and / or input based components. The first page makes it possible to create a new customer, and on the second page, the user can enter a shipping address. # Module Reuse. i.e this.$store.dispatch(`${Action.LOGIN}`, {email: this.email, password: this.password}), You will notice I make use of the Material Design Component Framework to assist in developing the Presentation views of my code. Then reuse them in the whole app. You will notice we also make use of String Interpolation to to refer to the Mutation, using the back tick ` and referring to our constants in our mutation commits i.e. We are now ready to start developing our Authentication Module which in this example is going to focused around making use of Firebase Authentication. Let’s take a short look at what we’ve achieved and how this approach of structuring a Vuex store is different to more traditional approaches. For example, the vuex-router-sync library integrates vue-router with vuex by managing the application's route state in a dynamically attached module. We will only take a look at our Login and Logout functionality but the principles now apply wherever we make use of the Authentication store in our application. Having an index.js file in a folder lets you perform an import from the folder implicitly without specifying the index.js in the import statement. If you need to support module reuse or to use modules with NuxtJS, you can have a state factory function generated instead of a static state object instance by using stateFactory option to @Module, like so: We have drastically simplified this file now and any developer who opens this can quickly at a glance get to understand what the code conveys. We will add our common names for our actions and mutations in the file as constants. Using Vuex Modules. Store ({state: {}, modules: {counter, hgapi}}) Module re-use, use with NuxtJS. This is useful when you want to reuse the state object especially for module reuse. We are also going to take this opportunity to to implement an approach in order to reduce the use of Magic Strings in our code. These are great reasons and definitely are always my first considerations. We can now refactor our store and move the code to the appropriate files. Update from 2019: I wrote this article about a year ago, and I changed my mind about a few things regarding the use of Vuex at scale since then. We are also going to examine some additional file organisation techniques and strategies we can use in order to introduce concepts from strongly typed languages into JavaScript code in order to help reduce errors introduced by over use of Magic Strings and numbers. To make it a little bit more convenient to wire the state, defined in the form modules, to the form fields in the component, we’re exporting custom vuex-map-fields helper functions. All three form modules are located in src/store/modules/forms. By using a factory function that creates new Vuex store modules for us, we can reuse all the repeating boilerplate code and pass different implementations of specific dependencies to adapt to the needs of our various content types. Details # mutations. Sometimes we may need to create multiple instances of a module, for example: Creating multiple stores that use the same module (e.g. Dynamic module registration makes it possible for other Vue plugins to also leverage Vuex for state management by attaching a module to the application's store. # Vuex.Store Constructor Options # state. Vuex uses a single state tree. // See: https://github.com/maoberlehner/vuex-map-fields#custom-getters-and-mutations. I have been going back and forth with individual Vuex Modules for my “widgets” (and I say widgets since they are more than a standard component), or putting all the “widget” states in a global store. However, probably the best reason is … For maximal reusability, we’re using form modules representing certain sections of our two forms. In ES6. Our existing store.js we developed in How to Use Vuex and Vue-Router in a Vue.JS Project . We are going to implement a types file which will contain constants we will use to define action and mutation names. Remember that Vuex makes sense if the code is reused or if there are distant components that need to communicate. Import Vuex, Add the store option to the root Vue instance. You might have to adapt certain aspects of it to your own needs. Because we’re not globally registering all of our modules upfront, it’s possible to use webpacks code splitting feature in combination with the vue-router, to dynamically load components and their associated store modules. Representative for the two other form modules, which are pretty similar, we’ll take a closer look at the contact.js form module. By using a factory function that creates new Vuex store modules for us, we can reuse all the repeating boilerplate code and pass different implementations of specific dependencies to adapt to the needs of our various content types. Moreover, I plan to write a book about this topic, and you can follow me on Twitter or subscribe to my newsletter if you want to stay up to date. To help with that, Vuex allows us to divide our store into modules. I have chosen to take this approach as it suitable for the needs of this module and for the future growth of the additional complexity we will introduce at the later stage. If we take our example we’re going to be dealing with in this tutorial Authentication using Firebase this is going to be a recurring theme in any project. If you want to take a closer look at those models, you can check out the code in the GitHub repository. Vuex provides a centralized store for all application components for better maintainability and management of applications. Every .js file inside the store directory is transformed as a namespaced module (index being the root module). So we can create one of them now. It doesn't make sense to do a getter if you only use it once and it doesn't communicate with another component, instead, you should create a computed property in the same component that needs it. The root state object for the Vuex store. A cart should have a list of items/products that the user adds to it. Because this is only a demo application, the api() util is a fake implementation, which simulates a failing request every other time, to demonstrate both, error and success handling. For example, a notifications module that provides some notification components and a store module that extends your application store, adding a new module that’s accessible from everywhere in your app. We can now add some additional folders to separate our sections of store. In order to be able to reuse reactive data from the store's state, you should use computed properties. Building a Vuex module factory. We’re going to try think of a good name for our folder. We then create a blank index.js file in store directory and each of the subsequent child directories we created. 一、什么是module？ 背景：在Vue中State使用是单一状态树结构，应该的所有的状态都放在state里面，如果项目比较复杂，那state是一个很大的对象，store对象也将对变得非常大，难于管理。 Để avoid stateful singletons in the SSR khi option runInNewContext là false hoặc 'once'); Đăng ký 1 module nhiều lần trong cùng 1 store Want to get an infrequent reminder that I'm still alive? After we’ve created the necessary modules, we register them in the store. Each module can contain its own state, getters, mutations, actions and even other nested modules. Both ways work as expected but the module method is preferred, keeping each module small vs 1 massive file jammed with getters, actions, mutations. Module Reuse. The approach outlined is just one of the approaches you can use, however it is my preferred approach if you are going to work on large complex projects, helping to isolate your store logic to specific modules. `${[Mutation.LOGIN]}`, Lets add code to our src/store/auth/getters/index.js, Then our touch src/store/auth/mutations/index.js, and finally src/store/auth/state/index.js, We can add the following code to our src/store/auth/index.js. type: Object | Function. We will create useful folder structure to help organise our code. Although most of this article is still relevant today, I highly recommend you also read my article about possible alternatives for Vuex and how you can decide when to use Vuex over an alternative solution. So implement an approach in one project and it works you probably want to re-use across all your projects. You can check out a demo of the project here (make sure to open your browsers developer tools to see console output). Let's take the cart module as an example. Let’s see how to do that. A vuex module can represent anything dividable in your app. But I hope this article will serve as an inspiration for a powerful solution which fits your specific use case. At the end of the file, the customer store object is exported. Now that we’ve created our store modules, it’s time to wire everything up. We’ll use them in the next step when building the component for the customer form. This module is responsible for holding the state for our contact related form fields (email and phone). Because the customer.js Vuex module is a lot more complicated than the previous files we’ve seen so far, to make it a little easier to explain and comprehend, I’ll break it up. When I was researching possible approaches for handling the state of big, Vue powered applications with Vuex, it was pretty hard to find good examples. If youve been following along in this series of Vue tutorials on how to make use of Vuex and Vue-Router in a Vue Project and how we can implement Firebase authentication in a Vue Project . This instructor-led, live training (online or onsite) is aimed at developers and programmers who wish to create, manage, and update Vue applications using Vuex. Vuex — the most powerful state management library in Vue.js ecosystem, but missing a small functionality that exists in most projects: “Reset all modules to its initial state” Form fields are mapped to a Vuex store which is mapped to an API request. This makes the app bundle size smaller which can have a huge effect on the initial loading time, especially with large scale applications. The reason for this is, that we move most of the logic into separate modules. We now import our types file and use string interpolation to refer to action we want to call. Place it into the new folder ~/composables as a useNotes.ts file - we're operating with Nuxt structure. # Vuex.Store Constructor Options # state. Hi, please, how i can make a new instance of module? Post was not sent - check your email addresses! Sorry, your blog cannot share posts by email. Taking the opportunity to Modularize code enables you to reuse modules across several projects.

To make a Vuex store easier to scale, it can be separated into modules. I ended up guessing that I could declare my store module name as a parameter (maybe it’s a given, but I’m still learning Vuex ), so I ended up creating a pull request with an example of this for the README, just in case. This is useful when you want to reuse the state object especially for module reuse. Our new modularized store is ready for use. Vuex mapstate modules.

In this article, we take a look at a possible way to structure a Vuex Store for a large-scale application. Modules. To avoid stateful singletons in the SSR when the runInNewContext option is false or 'once'); Register the same module multiple times in the same store. Most of what we’re doing is to map actions, mutations and fields from the store modules to our component. Follow me to get my latest Vue.js articles. We’re using the createCustomer() model helper function, to create a data structure, which is compatible to what our API expects, from the data stored in our address, contact and name form modules. There are a number of reasons why you would want to make use of Vuex-Store modules besides the previous mentions of organisation, clean code, test-ability and maintainability. If you want to see the application in action, you can go to the live demo on Netlify and you can see the full code on GitHub. This instructor-led, live training (online or onsite) is aimed at developers and programmers who wish to create, manage, and update Vue applications using Vuex. If you pass a function that returns an object, the returned object is used as the root state. The following approach is what I came up with so far. Just imagine what those the size of those files would be in a larger more complex project. The shipping address form component on the other hand, makes use of only the contact.js and address.js form modules. These are great reasons and definitely are always my first considerations. Designing our store structure in a way which makes certain modules reusable, can have an enormous positive impact on maintainability and also bundle size, when the application is getting bigger. It can, for example, represent a modal box, multi-step form, cart, you name it. type: Object | Function. This will be bloated is our app grows big. Your state value should always be a function to avoid unwanted shared state on the server side. To avoid stateful singletons in the SSR when the runInNewContext option is false or 'once'); Register the same module multiple times in the same store.
