推荐答案
您将 jquery 插件 javascript 文件直接放在 app 文件夹中，以便为客户端和服务器加载 javascript 文件.
You are putting jquery plugin javascript file in app folder directly,so that javascript file will be be loaded for client as well as server.
根据 Meteor 文档:
客户端从以下位置加载 javascript:project/public 和 project/client
服务器从以下位置加载 javascript:project/public 和 project/server 文件夹.
As per Meteor documentation:
Client loads javascript from: project/public and project/client
Server loads javascript from: project/public and project/server folders.
从 v1.0 开始，Meteor 在客户端内部使用 jQuery，因此您可以直接使用您的库，而无需添加 jQuery.但是，建议您将 jQuery 显式添加到 Meteor 项目中:
As of v1.0, Meteor is using jQuery internally in the client, so you can use your library directly without adding jQuery. However, it's recommended that you add jQuery to your Meteor project explicitly:

Meteor 文档深入解释了JavaScript 文件是如何加载的以及静态资源应该放在何处(CSS，图像).
The Meteor docs explain in depth how JavaScript files are loaded and where static assets should go (CSS, images).
