Is there any way to have global variables or global data in v8cgi?

Is there any way to have global variables or global data in v8cgi?

Yes, by writing "global.myVariable = 123;"

Note, however, that global variables are generally considered a bad practice.


Sincerely,
Ondrej Zara

But global object is per HTTP request right?
So will the data stored in global object will be preserved across the
requests?

Even if we use reuse_context functionality, still for each request,
all the global object properties get clears.

Yes, exactly. In CGI scenario, for instance, every request means new single v8cgi process - there is no universal, reliable and generic way to preserve data across requests. An optimal solution seems to be memcached...

Is that same for FastCGI?

In particular I'd like to create online game and preserv "Game room" object in shared memory.

Wouldn't it be better to use sessions for that?

[Ondřej Žára]

Yes, the same holds for FastCGI. In FastCGI, the process itself runs ifinitely, but every request gets a fresh JS context.

May I suggest switching to websocket, as opposed to Apache? There is a built-in websocket server module in TeaJS, which is far more suitable for a game room (there is also a sample websocket echo server to get you started...).
