Using Components

To use Laravel components, you need to declare dependencies in your application's composer.json file. Here is an example of bringing in the Auth component:

<code>"require": {
    "laravel/framework": "^8.0",
    "laravel/ui": "^2.0"
}</code>

After installing the dependencies, you can use the component in your code. For example, the following is an example of using the Auth component for user registration:

<code class="php">// 创建新用户
$user = new User([
    'name' => $request->input('name'),
    'email' => $request->input('email'),
    'password' => bcrypt($request->input('password')),
]);

// 保存用户
$user->save();</code>

Advantages

Using Laravel components has the following advantages:

• Reusability: Components can be easily reused in multiple projects, saving time and effort.
• Consistency: Components follow Laravel's design patterns, ensuring application consistency across the entire code base.
• Security: Components provide secure application development by following Laravel best practices.
