9 years ago What error do you get when you try to set this up in Heroku, it is been more then a year ago that I played with heroku, because of the custom buildpack and the updates of the dart sdk ...

9 years ago Oké I am going to try running this application in 2 modes! One with DART_SERVE_URL and one time without see if it makes a difference.
jorishermans
commented
9 years ago It is starting and working correct locally in these 2 modes :)
Did you run pub build? so a build folder is been created on heroku ...
It is also strange that he says noMethodFound exception ...
giolaq
commented
9 years ago Locally it works, on heroku running pub build automatically, it shows me this errors. I'll try on Google Cloud soon.
jorishermans
commented
9 years ago Yes indeed, but I remember that I needed to activate websockets on heroku ... don't know if that is still necessary
jorishermans
commented
9 years ago I will do a try too tomorrow. What is the version of the dart sdk on heroku ... I guess that is the same as on our computers ... I need to get some sleep ;) ... keep me posted ;)
It seems like he could not initiate servingAssistent ... strange, typically something environmental ... some small difference between local and heroku ...
giolaq
commented
9 years ago Yes me too, let's have some sleep! :) Dart version is 1.8.5 same in heroku.

I am failing on installing Dart VM what is your DART_URL_SDK? Using this buildpack https://github.com/igrigorik/heroku-buildpack-dart
jorishermans
commented
9 years ago It builds it correctly, now I need some access to the logs, will try to deploy another simple app tomorrow! And compare it, the tooling in heroku are improved, I like it :)
giolaq

9 years ago I cannot make it work with GClud/Docker too, It seems docker build can't find pubspec.yaml ERROR 2015-03-08 13:56:34,611 containers.py:283] pubspec.*: no such file or directory I'm following https://www.dartlang.org/server/google-cloud-platform/app-engine/
jorishermans
commented
9 years ago pubspec.yaml is something essential ... still try to get it working on heroku ;-) ... I know that dart hosting is an issue ... not a lot of options and most of them are all very custom.
giolaq
commented
9 years ago Yes pubspec.yaml is in the directory but it's seem that pubspec.* expression is not working identifying the right file
jorishermans
commented
9 years ago You can maybe ask this in the dart cloud mailing group ...
giolaq
commented
9 years ago Any news? I'm trying in DigitalOcean + Dokku and have some others problems. I want to have a server side platform to run a game starting by this in a conference. Thank you for the help
jorishermans
commented
9 years ago I have it almost working, some tweaks and some more time and then you will have a good solutions ...
jorishermans
commented
9 years ago Great news :) I got it working on Heroku.
ClientServe was put to false so it crashed, because port environment variable was not set ...
http://forcegame.herokuapp.com/
Can you test this too, I am very sorry that it took me so long ;) It give me also some great insides into heroku so that is great too. So lets finish this game now :)
giolaq
commented
9 years ago Thank you! I tested your link, but playing the client don't show the list with other players, and sometimes the server goes off showing "Disconnected - start 'bin/server.dart' to continue"

After a period of inactivity the heroku server puts himself into sleep mode. So you need to refresh the page. With pooling you want have that ;)
I filled in my name and then in another window I am filling in another name and then I see a list of opponents!
Well it is indeed not good ... but we can make it better.
jorishermans
commented
9 years ago I see what is going on, I fixed it, it is an old demo version of 'Force' so it is not that up to date anymore ...
jorishermans
commented
9 years ago I cleaned up some code in tictactoe. Added broadcast streams in forceclient and added some functionality to keep track of not sended packages when the client don't reaches the server ... test it out and if you find it a good version I can publish it to pub :)
giolaq
commented
9 years ago Thanks, but using http://forcegame.herokuapp.com/ gives me empty opponent list in all the tests I've done. Also deploying to my server. I'm trying with Chrome, Firefox and Safari. When I press Enter after filling a name, in the console there's WebSocket not connected, message Instance of 'aa' not sent WebSocket not connected, message Instance of 'aa' not sent
jorishermans
commented
9 years ago And in dartium? What does it give you as error? Instance of 'aa' doesn't tell me a lot. I really want to solve this ...
I probably forgot something ...
jorishermans
commented
9 years ago Yes I see, you are not connected to the server yet ... so it will not send the websocket message, but when you are it will do that, it saves it now in notSendedPackages. It would be nice if you could help me give me some more insides in your encounters still, it is hard to solve something when you don't have that problem.
jorishermans
commented
9 years ago Was it working better locally before my changes yesterday?
giolaq
commented
9 years ago Locally is working, deploying on a remote server and playing doesn't show the right opponents list. Can you see the right list in http://forcegame.herokuapp.com/ ? I need to push it on my heroku and debug it.
jorishermans
commented
9 years ago Ok I see, well I see a list on http://forcegame.herokuapp.com/ and I can play against another tab. Yesterday I had also the problem of Websocket not connected, so I added offline behaviour in dart force, maybe there is still something not correct in that code.

It seems on my laptop ( OSX ) that after "chosing a socket implementation!" the client don't connect to the ws. Running it locally wrote instead "connected!" after the previous step.
jorishermans
commented
9 years ago I see, I am working on a windows 7. I don't have a mac :s
It has maybe something todo with websockets, os x, heroku, ...
giolaq
commented
9 years ago In linux + Chrome is ok, on Android + Chrome is not working,
jorishermans
commented
9 years ago I have an android phone, so I will debug it and see what I can do on that platform.
giolaq
commented
9 years ago :O Now is working, http://forcegame.herokuapp.com/ :smile:
jorishermans
commented
9 years ago The html template had a hidden-xs on the opponent list, I removed it so you should see it now on an android phone.
Heroku also disconnects a websocket after 50 seconds of inactivity.
"The last important piece of logic is a keep-alive for the WebSocket connection. The request timeout window on Heroku still applies to WebSocket connections. An application must send some data across the connection once every 55 seconds or it will be closed by the router. The original chat sample included a robot that would send a message to the room once every 30 seconds. This fulfills the keep-alive requirement." - From an article on Heroku.
So I will implement the 'ping pong' protocol for websockets. We are getting closer ;-)
giolaq
commented
9 years ago Thank you! :+1: All is up and running now
jorishermans
commented
9 years ago Ping pong protocol is working now, you can check it on http://forcegame.herokuapp.com/
I don't know if the outside api, is good with.
fs.activateKeepAlive();
What do you think?
jorishermans
commented
9 years ago When there are still some issues I am glad to hear that ;)
What is the right configuration to run this example on Heroku? I have manually create a "views" directory because the server part look for it. But from the other errors I think I've to set the right ForceServer fs = new ForceServer(host: ".... configuration. Any Hints?
