如何在 Angular 中启用 PouchDB Debug

How to enable PouchDB Debug in Angular

本文关键字：启用 PouchDB Debug Angular      更新时间：2023-09-26

我正在开发一个原型Web应用程序。我使用Yeoman创建了一个带有Grunt，NPM和Bower等的Angular应用程序。PouchDB API 说你可以像这样启用调试：

PouchDB.debug.enable('*');

但是，这需要安装节点调试模块。我尝试通过 bower 安装它并在我的索引中引用它.html但无济于事。如何将调试模块注入 Angular 中？还是此功能仅在 PouchDB 从 Node.js 服务器运行时可用？

编辑：

我得到的确切错误是下面。它抱怨的台词是：PouchDB.debug.enable('*');

当您使用 PouchDB 时，调试模块已经安装。除了呼叫PouchDB.debug.enable('*')之外，您无需执行任何操作。:)

请注意，在 PouchDB v7.0.0 中，需要加载一个单独的插件。
