[99s-extend] [ANN] The Erlanger Playbook early release

Hello,
+
+I hope it's OK for me to announce on erlang-questions: The Erlanger 
+Playbook, a book about software development using Erlang, has been 
+*early* released!
+
+The book is meant to be the missing developer manual. It covers all 
+steps from the start of a project to its release including writing code, 
+documentation and tests.
+
+There are books for learning Erlang, for running Erlang in production, 
+but not much for modern Erlang development. This is where The Erlanger 
+Playbook comes in.
+
+This is an early release. An update will be sent to everyone about every 
+month or so. I plan to cover anything that relates to the development of 
+Erlang software, ie the "dev" in "devops". Many tools and techniques 
+will be covered in future updates.
+
+We will do a print book if there is enough interest once the book gets 
+finished, but we're a few months off for now. :-)
+
+You can get more information here:
+
+   http://ninenines.eu/articles/erlanger-playbook/
+
+Thanks for your interest!

[99s-extend] Help to use frameset in index.html

+

hello,
+
+First of all I would say I am a beginner in Cowboy web server, so probably
+I made something wrong, that is why I got the "fault", what I got.
+
+I would like to build up web page, where the client can communicate to
+server, and server can do the same to client, if client does not send
+anything to server too. The Cowboy has the websocket example, what does
+what I would like to do.
+
+There is only one thing is missing what I would like to have. This is the
+"frameset". My idea is to build the index.html using framsets. I made this
+changes, and I build up the html files for the frames, and of course I set
+these in the index.html.
+
+Here is how the index.html looks like
+    <html>
+
+    <head>
+    <title>Welcome to Websocket example 2</title>
+    </head>
+
+    <frameset rows="64,*">
+        <frame name="top_frame" noresize="noresize" scrolling="no"
+src="frame_top.html">
+        <frameset cols="450,*">
+            <frame name="left_frame" scrolling="auto" src="frame_left.html">
+            <frame name="right_frame" src="frame_right.html">
+        </frameset>
+        <noframes>
+        <body>
+
+        </body>
+        </noframes>
+    </frameset>
+
+    </html>
+
+This is how the priv folder looks like
+-----------------------------------------------------------
+    ls priv/
+    frame_left.html  frame_right.html  frame_top.html  index.html  static
+
+This is how I changed the websocket_2_app:start/2 function
+-----------------------------------------------------------
+    Dispatch = cowboy_router:compile([
+        {'_', [
+
+            {"/", cowboy_static, {priv_file, websocket_2, "index.html"}},
+            {"/[...]", cowboy_static, {priv_dir, websocket_2, ""}},
+
+            {"/websocket_2", ws_handler_2, []},
+            {"/static/[...]", cowboy_static, {priv_dir, websocket_2,
+"static"}}
+        ]}
+    ]),
+
+After compile and make release package of the app, I can reach the
+webserver on the port 8080, but some connection does not set up correctly.
+The following texts are present in the browser
+    DISCONNECTED
+
+    ERROR: undefined
+
+    Connecting to: ws://localhost:8080/websocket_2
+
+I made a dbg trace on all cowboy modules, to start some kind of
+troubleshooting. In the "tons" of printout I can see this one. So in the
+bottom of this, there is an {error,enoent}. It comes when tries connect to
+the socket. But unfortunatelly I do not have idea what may cause this :-(

The {error, enoent}, especially there, is probably just because the 
+browser is trying to fetch the favicon.
+
+Your issue is that Websocket won't connect, so it has nothing to do with 
+cowboy_rest. Try tracing cowboy_websocket or enable SASL to have more info.

hello,
+
+According to you grate support I got from you at yesterday, I could
+continue my project, where I use Cowboy webserver and using Websocket. Now
+I made an own web page with basic features I need, so the server and client
+can communicates to eachother. I like it.
+
+Now I would like to step forward, and I would like to implement a
+Request-Response mechanism. I read few articles in to this topic, and all
+of them has mentioned this "feature" is not part of the Websocket standard.
+They were suggested to use some sub-protocols for this, but I did not see
+any written in Erlang.
+
+So, I would like to ask you, do I understand right that Cowboy does not
+have this feature too? If so, do you have some idea how can I implement a
+basic request-response mechanism? Probably one of you guys in this forum
+have some idea.
+
+Btw, the links I read about this topic:

I think you'd have to roll your own, you just need some way to correlate
+<http://www.enterpriseintegrationpatterns.com/CorrelationIdentifier.html>
+responses
+with the originating request. OTP does something similar under the hood
+with gen_server calls <http://www.erlang.org/doc/man/gen_server.html#call-2>
+.
+
+It's also possible to treat the ws connection as a messaging channel, and
+use something like selective consumer
+<http://www.enterpriseintegrationpatterns.com/MessageSelector.html> to
+de-multiplex the messages. e.g. you could add a type/channel field to each
+message, and only subscribe to those messages.
+
+Remember that once you move into an async world, there are no guarantees
+that you will receive a response! So you need to start thinking about
+timeouts etc.

+
+Cowboy only comes with the Websocket protocol itself, all sub protocols 
+and mechanisms you want can then be implemented on top of it.
+
+I strongly recommend not to do RPC. Just send events to the server and 
+let the server send events to you. The difference is in the fact that 
+RPC tracks what requests were sent to tie requests and responses 
+together, while an event channel does not. You just send what the user 
+is doing and the server sends you what it wants the client to update or 
+do. Stay as stateless as possible.
+
+If you need to manage state to update the interface (locking a form 
+while waiting for the result, for example), do use timeouts to avoid 
+locking endlessly.
+
+Try and experiment, it's not very complicated. :-)
