问题描述

我想使用与。

我首先在 / public

中复制整个Dojo Toolkit树，然后将其包含在客户端包含：

Then, I include it on the client side with:

<script src="/dojo/dojo.js" data-dojo-config="async: true"></script>`

一切正常，除了Meteor实际上是监视 / public 中的每个文件进行更改，以便它可以重新启动服务器。在 localhost：3000 的第一个请求中，这实际上导致了很长的延迟。

Everything works fine, except Meteor is actually monitoring every single file in /public for changes, so that it can restart the server. This is actually causing a very long delay during the first request on localhost:3000.

有没有办法阻止Meteor从某个目录中查看文件？

Is there a way of preventing Meteor from watching files from a certain directory?

Dojo Toolkit是10k +文件，所以我收到了EMFILE错误，用

Dojo Toolkit is 10k+ files so I get the EMFILE error stated here, corrected with

sudo sh -c 'echo 16384 > /proc/sys/fs/inotify/max_user_watches'

推荐答案

意识到这是重复的：

请参阅：

这是我的一个主要问题。我必须提供〜12000个静态图像，我最初放入公用文件夹。这导致节点不断使用一个CPU内核的近100％。使用有限的内存，应用程序崩溃。

This was a major problem for me. I have to serve ~12000 static images, which I initially put into the public folder. This caused node to use nearly 100% of one CPU core, constantly. With limited memory the app crashes.

目前使用的解决方法

创建文件夹 public /.# static / 并将所有静态资源移动到其中。这个文件夹没有被流星

前缀url与静态（ /img/cat.png - > /static/img/cat.png）

 
  安装mime npm包

create the folder public/.#static/ and move all static assets into it. This folder isn't watched by meteor
prefix urls with static (/img/cat.png -> /static/img/cat.png)
install the mime npm package

cd ~/.meteor/tools/latest/lib/node_modules/
npm install mime

 创建一个rawConnectionHandler来为资产提供服务（信用：）
服务器/ static_files_handler.coffee

create a rawConnectionHandler to serve the assets (credits to: https://stackoverflow.com/a/20358612)server/static_files_handler.coffee

fs = Npm.require('fs')
mime = Npm.require('mime')
WebApp.rawConnectHandlers.use (req, res, next) ->
  re = /^\/static\/(.*)$/.exec(req.url)
  if re isnt null # Only handle URLs that start with /static/*
    filePath = process.env.PWD + "/public/.#static/" + re[1]
    type = mime.lookup(filePath)
    data = fs.readFileSync(filePath, data)
    res.writeHead 200,
      "Content-Type": type

    res.write data
    res.end()
  else # Other urls will have default behaviors
    next()
  return

 
 
此方法的限制：
 
 不适合使用查询参数提供资产。正则表达式还将匹配/static/html/image.html?src=/static/img/cat.png尝试提供包含参数的文件名的文件。这很容易改变。
 
  Meteor完全不知道这些文件，因此它们不会被包含在Appcache清单中。如果您想使其脱机使用，请查看我添加到 
 
 
not suitable to serve assets with query parameters. The regex would also match /static/html/image.html?src=/static/img/cat.png trying to serve a file with the filename including the parameters. This is easy to change.
Meteor is completely unaware of the files, they therefore don't get included into the appcache manifest. If you want to make them available offline, check out the addPaths option I added to https://github.com/buildhybrid/appcache-extra
如果您不想解决问题，请考虑为外部服务（例如AWS S3）。
If you don't want to work around the problems, consider serving the assets from an external service (ex. AWS S3).
