Does meteor run ios-device not build from scratch every time you run it? While meteor run ios serves the latest code, ios-device seems to serve the code that was built before. I have checked documents but haven't found anything related.
Are you building against a server other than your local server (i.e. something other than localhost).
If so, if that server has and old version deployed, it may be hot code pushing old client code when your mobile app starts up!
I'm using
Meteor 1.0.2.1
sanjo:jasmine 0.9.1
velocity:html-reporter 0.3.2
https://doctorllama.wordpress.com/2014/09/22/bullet-proof-internationalised-meteor-applications-with-velocity-unit-testing-integration-testing-and-jasmine/ says I should be able to use console.log() to see output in the console.
But nothing happens for me.
If I move the call out of tests/jasmine into client/ or server/ then the output is on the terminal where meteor is run.
The html-reporter also has a section called Logs. Looking at the code it appears to have a reactive collection on VelocityLogs. My google-fu is failing me as I can find no information on how to get any output to display in this section.
What is the correct way of logging in jasmine tests?
In Chrome the client side logs are visible through the JavaScript Console.
But I still don't know where the server side logs might be.
I've run with DEBUG=1 JASMINE_DEBUG=1 VELOCITY_DEBUG=1 VELOCITY_DEBUG_MIRROR=1 and the console logs do not appear either.
Edit:
I've created a repo to provide an example of the problems at https://github.com/baerrach/meteor-velocity-issue-223.
If you are running server integration tests and they're not appearing, you may have found a bug!
Try running with:
VELOCITY_DEBUG=1 meteor
The logs should appear in the same place as the main meteor logs appear, prefixed with [velocity-mirror]
I have created my first meteor app today and am kind of stuck. Everything works extremely well on localhost:3000, very responsive etc. It is a simple task app, where users can post tasks to a feed that displays all tasks an then claim those tasks, removing them from the general feed and putting them into their personal feed. But when I deploy it to a meteor.com server, everything breaks.
This is the js file
https://github.com/valentin-zambelli/brokenjs/blob/master/mvp.js
Accounts.ui.config({
passwordSignupFields: "USERNAME_ONLY"
});
gets ignored and whenever I try to post a new task the page reloads, getting stuck on app.meteor.com/?text=some+new+task and doesnt display the task in the general taskfeed.
I have removed the insecure and autopublish package. Is there anything I am missing here? It kind of seems as if it uses an older, broken build. I also get the ReferenceError: Can't find variable: require when deploying, but I can't really figure out where this is coming from.
I hope someone can help me.
Ok, it was an insanely stupid mistake on my part: The mongodb was still in an older state and caused a conflict. If you have problems deploying your meteor app try
meteor deploy myapp.meteor.com -- delete
This will delete all resources on the server, including the database. Then do a simple
meteor deploy myapp.meteor.com
On localhost, the app works just fine.
On EC2, the app runs behind nginx. It loads into the browser, but nothing shows up. The browser console displays an Error
TypeError: 'undefined' is not an object (evaluating 'Package["service-configuration"].ServiceConfiguration')
I have no idea how to tackle this problem. Any help appreciated.
EDIT
NGINX is not the problem. The same behavior if I access meteor server directly.
Running "meteor add service-configuration" does fix the above mentioned error, but the absence of the error does not fix the observed behavior, that the app does not render on EC2 whereas it does render when started on localhost. (The error message was the only visible difference between EC2 and localhost. So I suspected that would be the cause. Now that hypothesis must be wrong.) So the problem still persists.
Problem Solved. The Lesson:
Meteor has a debug mode and a production mode. The two may behave differently. On localhost, meteor runs in debug mode per default. On deploy to meteor.com or per mup, the default is production mode. To run meteor in production mode on localhost, run meteor --production.
It looks like you're trying to access the service-configuration configs on your browser.
These are not available client side. This also affects your localhost app but it doesn't break your app (doesn't give you a blank page) because meteor is in debug mode.
In debug mode Meteor files are not concatenated so an error like this would go unnoticed, even if it is thrown on your js console. In production mode the error would halt the rest of your script (since everything is concatenated into a single file)
You need to ensure the code that is doing this only runs on the server side. In general it's not a good idea to have access to the service configuration data on the client side.
Looks like Arunoda and crew are adding a buildOptions.debug setting to the next version of MUP, which should allow you to deploy via MUP and have it act like it's running on localhost. See Arunoda's answer to a related question and (at least for now) documentation for the development version of MUP.
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.
I end up using console.log but this is very inefficient.
Update: I found the following procedure works on my Linux machine:
When you run Meteor, it will spawn two processes
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
You need to send kill -s USR1 on process2
Run node-inspector and you can see your server code
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" "$#"
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.
Can someone check this on Windows and Mac machine?
In Meteor 0.5.4 this has become a lot easier:
First run the following commands from the terminal:
npm install -g node-inspector
node-inspector &
export NODE_OPTIONS='--debug-brk'
meteor
And then open http://localhost:8080 in your browser to view the node-inspector console.
Update
Since Meteor 1.0 you can just type
meteor debug
which is essentially a shortcut for the above commands, and then launch node inspector in your browser as mentioned.
Update
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
Meteor apps are Node.js apps. When running a Meteor app with the meteor [run] command, you can configure the NODE_OPTIONS environment variable to start node in debug mode.
Examples of NODE_OPTIONS environment variable values:
--debug
--debug=47977 - specify a port
--debug-brk - break on the first statement
--debug-brk=5858 - specify a port and break on the first statement
If you export NODE_OPTIONS=--debug, all meteor command run from the same shell will inherit the environment variable. Alternatively, you can enable debugging just for one run, with NODE_OPTIONS="--debug=47977" meteor.
To debug, run node-inspector in a different shell, then go to http://localhost:8080/debug?port=<the port you specified in NODE_OPTIONS>, regardless of what node-inspector tells you to run.
To start node.js in debug mode, I did it this way:
open /usr/lib/meteor/app/meteor/run.js
before
nodeOptions.push(path.join(options.bundlePath, 'main.js'));
add
nodeOptions.push('--debug');
Here are additional practical steps for your to attach debugger eclipse:
use '--debug-brk' instead of '--debug' here, because it's easier for me to attach node.js using eclipse as debugger.
add 'debugger;' in the code where you want to debug.(I prefer this way personally)
run meteor in console
attach to node.js in eclipse(V8 tools, attach to localhost:5858)
run, wait for debugger to be hit
when you start meteor in your meteor app folder, you'll see that "debugger listening on port 5858" in console.
On Meteor 1.0.3.1 (update to Sergey.Simonchik answer)
Start your server with meteor run --debug-port=<port-number>
Point browser to http://localhost:6222/debug?port=<port-number>
Where <port-number> is a port you specify.
In your code add a debugger; where you want to set your break point.
Depending on where debugger; is invoked, it will either break on your client or server browser window with inspector opened.
I like to set breakpoints via a GUI. This way I don't have to remember to remove any debugging code from my app.
This is how I managed to do it server side for my local meteor app:
meteor debug
start your app this way.
Open Chrome to the address it gives you. You MAY need to install https://github.com/node-inspector/node-inspector (it might come bundled with Meteor now? not sure)
You'll see some weird internal meteor code (not the app code you wrote). Press play to run the code. This code simply starts up your server to listen for connections.
Only after you press play you'll see a new directory in your debugger folder structure called "app". In there are your meteor project files. Set a breakpoint in there one the line you want.
Open the local address of your app. This will run your server side code and you you should be able to hit your breakpoint!
Note: you have to reopen the inspector and go through this process again each time your app restarts!
As of Meteor 1.0.2 probably the best way for server-side debugging is directly via the new built-in shell: with running server run meteor shell. More info here: https://www.meteor.com/blog/2014/12/19/meteor-102-meteor-shell
I am not sure why it was not working for you.
I am able to use it by following steps on console (Mac).
$ ps
$ kill -s USR1 *meteor_node_process_id*
$ node-inspector &
Above steps are mentioned on https://github.com/dannycoates/node-inspector. It is for attaching node-inspector to running node process.
I wrote a small meteor package called meteor-inspector which simplifies the use of node-inspector to debug meteor apps. It internally manages the lifecycle of node-inspector and hence, the user does not need to restart the debugger manually after some files have changed.
For more details and concrete usage instructions take a look at https://github.com/broth-eu/meteor-inspector.
for meteor 1.3.5.2, run
meteor debug --debug-port 5858+n
n is a non-zero number, this will cause node-inspector use 8080+n as web port.
WebStorm, the powerful IDE free for open source developers, makes it much easier to debug server-side.
I've tested it on Windows, and the configuration was painless - see my answer.
A inspector that solve my issues is meteor server console. Here is the process I followed to install it:
In your project folder, add the smart package server-eval:
mrt add server-eval
For Meteor 1.0:
meteor add gandev:server-eval
Restart meteor.
Download crx Chrome extension file from here.
Open extensions page in Chrome and drag crx file to extensions page.
Restart Chrome.
Check the web inspector out to eval server side code:
In comparison with node-inspector, I have a clearer output.
If you prefer to use nodeJS' official debugger you can call NODE_OPTIONS='--debug' meteor and then (on a different shell) node debug localhost:5858.
