流星js应用程序/项目大的原因 [英] Reason behind the large size of meteor js apps/projects

问题描述

我一直在清理我的目录并注意到每个 Meteor.js 项目占用至少 77MB(通常更像是 150MB)！为了弄清楚发生了什么，我继续创建了一个新应用:

I've been cleaning up my directories and noticed that each Meteor.js project takes up at least 77MB (and typically, more like 150MB)! To figure out what was happening, I went ahead and created a new app:

meteor create myapp

此时文件夹大约占用7kb.但是在我这样做之后

At this point, the folder takes up about 7kb. But after I do this

cd myapp
meteor

文件夹大小气球高达 77MB.

the folder size balloons up to 77MB.

经过一番挖掘后，我设法确定增加.meteor/db 文件夹的大小.更具体地说，运行该应用程序会在 .meteor/db 中创建这些 local* 文件，每个文件都 >16Mbs.我打开了这些，它们主要是一长串 0000 和一些非 0000 在这里和那里.如果我开始做更多的事情——添加数据，到 Meteor.collections 等——大小会膨胀到 100+MB.

After some digging around, I managed to pinpoint to size increase the .meteor/db folder. More specifically, running the app creates these local* files inside .meteor/db which are each >16Mbs. I opened these and they're mainly just a long string of 0000s with a few non-0000s here and there. If I start doing more -- adding data, to Meteor.collections, etc -- the size balloons to 100+MB.

我的问题

• 这些文件有什么用?为什么它们这么大?
• 有什么方法可以让我的应用程序更小(压缩文件夹将大小减少到 1.8MB，所以很多额外的膨胀看起来可以以某种方式剥离.

推荐答案

在开发模式(默认)下运行meteor 会在你的 .meteor 目录下为你创建一个 mongodb 实例.它巨大，我知道.但别担心 - 这仅用于开发，因此您无需在本地主机上设置自己的 mongodb 实例.您可以随时运行以下命令进行清理:

Running meteor in development mode (the default) creates an instance of mongodb for you under your .meteor directory. It's huge, I know. But don't worry - this is only for development so you don't need to setup your own mongodb instance on your localhost. You can clean it up at any time by running:

$ meteor reset

当你去部署你的应用程序时，你将捆绑你的项目，其中不包含任何这些文件.

When you go to deploy your app, you will bundle your project which does not include any of these files.
