Re: [Cppcms-users] Interface with javascript

[Nazım C. B. <naz...@ne...>]

Hi,

In such cases, I usually prefer to use technique which is also central 
to Apache's Tapestry project. Basic structure is follows:

  * Boilerplate web page is generated by CppCMS as usual.
  * Boilerplate web page is using require.js.
  * On page load, require.js is loading web application's entry point.
  *  From the entry point, my own Javascript module do following:
      o Make an Ajax requests to web app via JSON-RPC.
      o On the server side, application is responding to requests with
        |cppcms::rpc::json_rpc_server.|
      o Javascript handles the server's response and apply changes.
      o In my case, changes are either loading additional require.js
        modules, or changing already existing DOM elements and their
        content on the page.
  * For things like user notification, I prefer to employ Server-Side
    Events; where initial registration for the events are performed from
    the Javascript module loaded by require.js.

For JSON-RPC, please see 
http://cppcms.com/wikipp/en/page/cppcms_1x_chat_json_rpc. For 
Server-Side Events, please see http://blog.cppcms.com/post/107.

Out of box, CppCMS doesn't provide any way to glue browser events and 
DOM to C++ objects. If you do not already know about, I highly suggest 
to take a quick look at tapestry.apache.org for getting an idea about 
how deep the rabbit hole may be :)

Hope helps.

Regards,
Nazim Can.
