Laravel is a popular PHP framework that provides a complete set of tools and features for building web applications, including routing, template engines, database ORM, etc. However, when building content-rich web applications, front-end rendering performance is an issue that cannot be ignored. Traditional front-end and back-end separation solutions often require requesting data from the server through AJAX and other technologies, and rendering the data to the DOM through JavaScript, which affects the performance and SEO of the website to a certain extent. Server-side rendering can render data into HTML on the server side, reducing JavaScript operations on the client and improving website performance and SEO effects. This article will introduce how to use the server-side rendering solution provided by Laravel.

Laravel’s server-side rendering solution

Laravel provides an independent server-side rendering package, Laravel View, which is specifically used to render views and provides a set of available The flexible configuration of the server-side caching mechanism can greatly optimize rendering performance. Using the server-side rendering solution in a Laravel application is also very simple. You only need to install the Laravel View package through composer and register the service provider in the application.

First, we need to add the following dependencies in the composer.json file:

"require": {
    "illuminate/view": "^5.6|^6.0|^7.0|^8.0"
}

Copy after login

Then, add the following code in the application's config/app.php file to register the service provider:

'providers' => [
    //...
    Illuminate\View\ViewServiceProvider::class,
    //...
],

Copy after login

Create View

In the server-side rendering scenario, we need to create the view and pass the data into the view in order to integrate the data and view into HTML on the server side. In Laravel, we can define views by creating Blade template files. For example, we create a local view /home.blade.php:

<!DOCTYPE html>
<html>
    <head>
        <title>{{$title}}</title>
    </head>
    <body>
        <h1>{{$content}}</h1>
    </body>
</html>

Copy after login

The above view defines an HTML document structure through Blade syntax, and uses the variables $title and $content to render the page title and content.

Rendering View

Rendering a view using the Laravel View package is very simple. We only need to use the class library provided by Laravel View and pass the view name and the data required by the view. This returns the server-side rendered HTML. For example:

use Illuminate\Support\Facades\View;

class HomeController extends Controller
{
    public function index()
    {
        $title = 'Laravel服务端渲染';
        $content = '服务端渲染是一种优化前端性能和SEO效果的方案。';

        $html = View::make('home', compact('title', 'content'))->render();
        return response($html);
    }
}

Copy after login

The above code first passes the view name and the data required by the view to the View::make() method to generate the server-side rendered view HTML. The HTML can be returned directly as a response to the client.

Set up cache

Server-side rendering takes up a lot of server resources. When the number of users is large, caching may be needed to optimize performance. Laravel View provides a flexibly configurable caching mechanism that can cache rendered views into cache storage such as file systems, Memcached, and Redis. For example, if we cache the view into the file system, we can use the following code:

use Illuminate\Contracts\Cache\Factory as CacheFactory;

class HomeController extends Controller
{
    public function index(CacheFactory $cache)
    {
        $title = 'Laravel服务端渲染';
        $content = '服务端渲染是一种优化前端性能和SEO效果的方案。';

        return $cache->remember('home', 60, function () use ($title, $content) {
            $html = View::make('home', compact('title', 'content'))->render();
            return response($html);
        });
    }
}

Copy after login

The above code first obtains the CacheFactory instance through dependency injection, and then uses the remember() method of the cache instance to cache the view rendered by the server. 60 seconds to save server resources.

Summary

This article introduces how to use the server-side rendering solution provided by the Laravel View package, including creating views, rendering views, and setting up cache. Server-side rendering is a solution for optimizing front-end performance and SEO effects, which can greatly improve the user experience and search engine ranking of the website. Using the Laravel View package, we can easily implement server-side rendering and optimize the performance and user experience of Laravel applications.
