Here's a small code example showing how you can quickly develop a Realtime Chat using a haxe/Flash Client and a haxe/Neko commandline Server that communicates using Haxe Remoting. This package contains the following files :

• ClientApi.hx : the API that the Server can call on the Client
• ServerApi.hx : the API that the Client can call on the Server
• Client.hx : the haxe/Flash Client Implementation, uses XMLSocket
• Server.hx : the haxe/Neko Server Implementation, uses ThreadRemotingServer
• app.hxml : the HXML file to compile the project
• server.n and server.bat : neko binary and batch file to start the server
• client.swf and client.html : the precompiled flash client.

Please open the HTML after starting the server and follow the instructions. The source code is very small (4 KB) and should be a good start for people wanting to develop realtime applications.

Download the sources
Note: Flash 8 target is not the default target anymore, so edit the file app.hxml to target flash 8 instead of flash 9 with the -swf-version 8 compilation option.

Trouble shooting

If you don't load the client from domain localhost you have to change host in both: Server.hx and Client.hx. Then the flash socket policy files will be served correctly.
