流星奇幻魔法进口 [英] Meteor Wonky Magic imports

问题描述

我已经使用流星已有一段时间了，并且遇到了意外的行为，我已经将文件系统设置为:

I've been using meteor for a little while now, and am running into an unexpected behavior I've got my file system set up like:

-workspace
    -client
    -server
    -shared
        -shared.js

在shared.js内，我创建了mongo集合:

Inside of shared.js I create my mongo collections:

Collection =新的Mongo.Collection('collection');

然后我可以在我的应用程序中的任何位置将它们作为全局变量引用.有趣的部分是:我从来没有在项目中使用过共享"一词，这意味着，我从未导入过此文件，我从未需要过此文件，它是独立加载的，并且无需通知即可工作.

I can then reference them as global variable from anywhere in my app. The interesting part is: I never once use the word 'shared' in my project, meaning, I never imported this file, I never required this file, it's loading by itself, and working without ever being told to.

我目前正试图在另一个项目中复制它，但无济于事.谁能解释为什么它在一个项目中而不是另一个项目中加载?以及我如何在第二个项目中得到这种行为?

I'm currently trying to replicate this in another project, to no avail. Could anyone explain why it's loading in one project, and not another? And how I might get this behavior in my second project?

研究完之后，似乎在我的第二个项目中，shared.js根本没有加载.

After looking into it, it appears that in my second project, shared.js is never loaded at all.

推荐答案

我猜您的两个项目不是使用相同的Meteor版本创建的.

自 Meteor 1.7 起，即使在 imports/文件夹之外，新项目也默认启用了惰性加载.

Since Meteor 1.7, new projects have lazy loading enabled by default even outside the imports/ folder.

这是由 package.json 文件中的属性 mainModule 制成的:

This is made by the property mainModule inside the package.json file :

"mainModule": {
  "client": "client/main.js",
  "server": "server/main.js"
},

如果要使用紧急加载(禁用延迟加载)，则必须从 package.json 中删除mainModule属性.

If you want to use the eager loading (disable the lazy loading) you have to remove the mainModule property from your package.json.
