在开发Laravel Nova用于管理的新项目时，我使用Google的网站管理员工具对其进行了测试。事实证明，该资源上的某些照片没有经过优化-它们的大小可以大大减小。使用node.js构建项目时，可以处理项目中的那些对象。为此有很多现成的软件包。用户仍然直接从站点管理面板上传了静止图像。当然，您可以在上传到站点之前优化每个图像，但是为什么不自动执行此过程。因此，这个想法诞生了，为Laravel Nova制作了一个包装：OptimalImage。
该软件包非常简单，因此不能伪装成为Laravel Nova创建软件包的完整指南。它没有涉及有关使用组件的可视组件的相当广泛的主题。如果出现关于组件的有趣想法，并带有可视组件-我将就该主题写一篇文章。
问题的提法
您要创建一个添加新字段的包。该字段将与
通常的图像加载字段不同，因为将对加载的图像执行优化。
环境的安装和配置。
要重复本指南中的所有步骤，您将需要一个带有Laravel和Laravel Nova的项目。Laravel Nova是一种付费工具，但在我看来，它的价格是可以承受的。
我在工作中使用过：
- PHP 7.3.16
- Laravel 7
- Laravel Nova 3.0
