This article will introduce to you how to use Laravel 8 with Vuejs to implement a single page application (SPA). I hope it will be helpful to you!
We all know that Laravel is a great framework! It allows full-stack engineers to build front-end and back-end websites in one stop. As a result, we can quickly build and deliver high-quality and secure web projects. But its power doesn't stop there.
There is so much more to explore and discover in Laravel. For example, we have written a series of Vue JS components that can be embedded into Laravel pages to dynamically provide UI interactions for users.
Interesting, right? But next we need to explore is, is it possible to build a single page application (SPA) in a Laravel project? Of course, why not! [Related recommendations:vue.js tutorial]
Before everything starts, we must first know why our project needs SPA? It is undeniable that SPA gives users a better experience. It makes pages load faster without reloading, allowing users to access the website even if they don’t have an internet connection! The examples go on and on.
Of course, this will also bring some disadvantages, so you still need to think twice before using it. Whether you are building an SPA or MPA (Multiple Page Application), make sure it meets your needs. But Laravel lets us build a MAP project by default, doesn't it? So I thought it was time for us to explore how to build a SPA in a Laravel project. Officially set off!
1 Our goal
What do we need to build at the end of this article? ? Quite simply, we're going to have a SPA with two pages inside. If we click on another page, it won't reload. Take a look at the final result of the project below.
2 Installation of Laravel and Vue JS
We will use the new Laravel as a starting point. Usually we can create a new project through the following command:
composer create-project laravel/laravel --prefer-dist laravel-vue-spa
Creation completed, you already have a new project. Then you need to install Vue JS in it.
composer require laravel/ui
The last thing that needs to be done is to integrate Vue JS into the Laravel project. Thank God, we can use the following command to help us integrate. Very simple.
php artisan ui vue
Don’t forget to compile Vue when changes occur.
npm install && npm run dev
3 Vue Router and file structure
Since in SPA, users can navigate to the page they want to reach through routing. So you need to install an additional library, Vue Router.
npm install vue-router
The most important step before implementing SPA is the file structure. Create new folders and files in theresources/jsdirectory. The code structure is as shown in the figure below.
Under theresources/jsdirectory, you need to create a new directory namedlayouts, andpagesTable of contents.layoutsThe content contained in the directory is as you think, and is used to display the layout files of the pages in thepagesdirectory. Confused? This will make the structure of the SPA clearer later in the process of implementing it.
Don’t forget to create therouter.jsfile to store all the routes we need.
4 SPA Implementation
It’s time to implement SPA! First, modify therouter.jsfile (inresources/js/router.js)
import Vue from 'vue'; import VueRouter from 'vue-router'; import Home from './pages/Home.vue'; import About from './pages/About.vue'; Vue.use(VueRouter); const router = new VueRouter({ mode: 'history', linkExactActiveClass: 'active', routes: [ { path: '/', name: 'home', component: Home }, { path: '/about', name: 'about', component: About }, ] }); export default router;
on the fourth and fifth lines, we need to be here Configure two pages, homepage and about page. I know that these two pages don't exist yet. We will create them later. On lines 9-24 we register all the routing information we need. Therefore each route object has path, name and component properties for rendering/display.
The routing has been prepared, what should we do now? We will display these pages in a layout file. RememberApp.vuealready in thelayoutsdirectory? Let’s create it.
Note lines 17-23, where the\tag is used. This routing link is similar to the\tag and is used to navigate between multiple pages. So the question is, where will the page be rendered? Look at the\tags on line 40, so the page will be rendered at the\tags.
Okay, the home page and about page have not been created yet. Open theHome.vuepage in thepagesdirectory.
AboutAbout Page
Until this step, we have set the routing for jumps between SPA pages and the layout of the display page. The last thing we need to do is to modify the entry file of Vue JS.
Openresource/js/app.jsand modify it.
/** * 首先，我们将重载项目中所有包含 Vue 或其他库的 JavaScript 依赖 * 使用 Vue 和 Laravel 构建健壮、强大的 web 应用，这是个很好的开始。 */ require('./bootstrap'); window.Vue = require('vue').default; import router from './router'; import App from './layouts/App.vue'; /** * 如下代码块可用于自动注册 Vue 组件。这将递归的扫描 Vue 组件目录 * 并按照其 "文件名" 自动注册。 * * 比如 . ./components/ExampleComponent.vue ->
在第 11 行和 12 行，引入了布局文件和路由文件，在 34 行，告诉 Vue 使用路由并在 36 行指定渲染到指定布局。
万事俱备，是时候告诉 Laravel 通过 Vuejs 实现 SPA 了。打开routes/web.php并在此创建其他入口。
where('any', '.*');
在如上代码中，我们告诉 Laravel 用户所有访问都将返回 resources/views/layouts/vue.blade.php文件。很明显，我们还没有这个文件，一起创建下。
Laravel
好了，这里有两个重点。第一个重点，在 16 行，创建了一个 id 为 “app” 的
标签。为何这很重要呢？因为 Vue 只能渲染到标致 id 为 “app” 的 p（或其他标签）上。如果你还记得resources/js/app.js的 35 行，我们告诉 Vue ，渲染到 id 为 “app” 的标签上。第二个重点是在 18 行，我们引入了编译后的 Vue JS 文件。
就先这样了。在你去测试前，请确保编译了 Vue JS 脚本：
npm run dev
然后运行服务并在浏览器中打开。
这！我们成功在 Laravel 中构建了 SPA！如果你从一个页面导航至另一个页面，将不会引发页面重载。
在本文完结前，我再说一点点，我们可以把 MPA 和 SPA 构建到一起。比如 SPA 页面只用于关于页。你需要为 SPA 添加一个端点/about/{any}，然后其他端点依旧是 MPA。或者哪怕项目中有多个 SPA 。通过 Laravel，也可以轻易的把其他 SPA 或者 MPA 或把他们一起构建到一个项目中！这不是就很赞吗！
是时候借宿了。在最后，我想说 Laravel 是一个非常棒的框架。你探索的越多，越能体验到它的强大。感谢您的阅读，我们下次见。
