流星:在服务器端调试 [英] Meteor: Debug on server side
问题描述
有人知道调试服务器端代码的好方法吗? 我尝试启用Node.js调试，然后使用node-inspector，但是它不显示任何代码.
Does anyone know a good method to debug server side code? I tried enable Node.js debug then use node-inspector but it does not show any of my code.
我最终使用console.log，但这效率很低.
I end up using console.log but this is very inefficient.
更新:我发现以下过程可在我的Linux机器上运行:
-
运行Meteor时，它将产生两个进程
When you run Meteor, it will spawn two processes
process1:/usr/lib/meteor/bin/node/usr/lib/meteor/app/meteor/meteor.js
process1: /usr/lib/meteor/bin/node /usr/lib/meteor/app/meteor/meteor.js
process2:/usr/lib/meteor/bin/node/home/paul/codes/bbtest_code/bbtest02/.meteor/local/build/main.js --keepalive
process2: /usr/lib/meteor/bin/node /home/paul/codes/bbtest_code/bbtest02/.meteor/local/build/main.js --keepalive
您需要在process2上发送kill -s USR1
You need to send kill -s USR1 on process2
运行节点检查器，您可以看到服务器代码
Run node-inspector and you can see your server code
我第一次尝试时，将/usr/lib/meteor/bin/meteor中的流星启动脚本的最后一行修改为
On my first try, I modify the last line on meteor startup script in /usr/lib/meteor/bin/meteor to
exec "$DEV_BUNDLE/bin/node" $NODE_DEBUG "$METEOR" "$@"
并在命令提示符下运行NODE_DEBUG=--debug meteor.这仅将--debug标志放在process1上，因此我只能在node-inspector上看到流星文件，而找不到我的代码.
and run NODE_DEBUG=--debug meteor on command prompt. This only put --debug flag on process1 so I only see meteor files on node-inspector and could not find my code.
有人可以在Windows和Mac计算机上检查吗?
Can someone check this on Windows and Mac machine?
推荐答案
在流星0.5.4中，这变得容易得多:
In Meteor 0.5.4 this has become a lot easier:
首先从终端运行以下命令:
First run the following commands from the terminal:
npm install -g node-inspector
node-inspector &
export NODE_OPTIONS='--debug-brk'
meteor
然后在浏览器中打开http://localhost:8080以查看节点检查器控制台.
And then open http://localhost:8080 in your browser to view the node-inspector console.
更新
从Meteor 1.0开始，您只需输入
Since Meteor 1.0 you can just type
meteor debug
本质上是上述命令的快捷方式，然后按照所述在浏览器中启动节点检查器.
which is essentially a shortcut for the above commands, and then launch node inspector in your browser as mentioned.
更新
在Meteor 1.0.2中，添加了一个控制台或外壳.在服务器上输出变量并运行命令可能会很方便:
In Meteor 1.0.2 a console or shell has been added. It may come in handy to output variables and run commands on the server:
meteor shell
