在 Laravel 8 中的模块化示例实现

1、在 GitHub 中搜索：laravel module，选择第一个结果：nWidart / laravel-modules。其支持 Laravel 中的模块管理。

2、参考网址：https://nicolaswidart.com/blog/writing-modular-applications-with-laravel-modules 。为什么要使用这个包，使用 laravel-modules 编写模块化应用程序。当涉及到编写更复杂、更大的应用程序时，发现 laravel 的默认结构很麻烦而且不理想。

3、要通过 Composer 安装，请运行以下命令。如图1

图1

PS E:\wwwroot\laravel-modules-demo> composer require nwidart/laravel-modules
Using version ^8.2 for nwidart/laravel-modules
./composer.json has been updated
Running composer update nwidart/laravel-modules

4、运行以下命令发布包的配置文件

PS E:\wwwroot\laravel-modules-demo> php artisan vendor:publish --provider="Nwidart\Modules\LaravelModulesServiceProvider"
Copied File [\vendor\nwidart\laravel-modules\config\config.php] To [\config\modules.php]
Publishing complete.

5、默认情况下，模块类不会自动加载。您可以使用 psr-4 自动加载模块。编辑 composer.json，然后运行：composer dump-autoload。如图2

图2

    "autoload": {
        "psr-4": {
            "App\\": "app/",
            "Modules\\": "Modules/",
            "Database\\Factories\\": "database/factories/",
            "Database\\Seeders\\": "database/seeders/"
        }
    },

PS E:\wwwroot\laravel-modules-demo> composer dump-autoload
Generating optimized autoload files
> Illuminate\Foundation\ComposerScripts::postAutoloadDump

6、参考文档：https://nwidart.com/laravel-modules/v6/introduction ，快速开启一个示例，使用 php artisan module:make Blog 生成你的第一个模块。 将生成以下结构。由于文档的版本是针对 v6 的，而现在程序的最新版本是 v8，因此，目录结构有所出入。如图3

图3

PS E:\wwwroot\laravel-modules-demo> php artisan module:make Blog
Created : E:\wwwroot\laravel-modules-demo\Modules/Blog/module.json
Created : E:\wwwroot\laravel-modules-demo\Modules/Blog/Routes/web.php
Created : E:\wwwroot\laravel-modules-demo\Modules/Blog/Routes/api.php
Created : E:\wwwroot\laravel-modules-demo\Modules/Blog/Resources/views/index.blade.php
Created : E:\wwwroot\laravel-modules-demo\Modules/Blog/Resources/views/layouts/master.blade.php
Created : E:\wwwroot\laravel-modules-demo\Modules/Blog/Config/config.php
Created : E:\wwwroot\laravel-modules-demo\Modules/Blog/composer.json
Created : E:\wwwroot\laravel-modules-demo\Modules/Blog/Resources/assets/js/app.js
Created : E:\wwwroot\laravel-modules-demo\Modules/Blog/Resources/assets/sass/app.scss
Created : E:\wwwroot\laravel-modules-demo\Modules/Blog/webpack.mix.js
Created : E:\wwwroot\laravel-modules-demo\Modules/Blog/package.json
Created : E:/wwwroot/laravel-modules-demo/Modules/Blog/Database/Seeders/BlogDatabaseSeeder.php
Created : E:/wwwroot/laravel-modules-demo/Modules/Blog/Providers/BlogServiceProvider.php
Created : E:/wwwroot/laravel-modules-demo/Modules/Blog/Providers/RouteServiceProvider.php
Created : E:/wwwroot/laravel-modules-demo/Modules/Blog/Http/Controllers/BlogController.php
Module [Blog] created successfully.

7、默认情况下，当您创建新模块时，该命令会自动添加一些资源，例如控制器、种子类、服务提供者等。如果你不想要这些，你可以添加 –plain 标志，生成一个普通的模块。将生成以下结构。如图4

图4

PS E:\wwwroot\laravel-modules-demo> php artisan module:make Auth -p
Created : E:\wwwroot\laravel-modules-demo\Modules/Auth/module.json
Module [Auth] created successfully.
