The version of Proxy is depend on whether you use master
or v0.10
. Latest stable (v0.10
) uses the 3.14
branch, while development (master
) stays with v8 bleeding_edge
(currently at 3.20
). So the more correct question is, "what version of proxies has v8 implemented?"
Work is being done on the proxy implementation, but it's a moving target right now. Referencing the proxy implementation ticket in the bug tracker (http://code.google.com/p/v8/issues/detail?id=1543) it looks like another round of changes are coming. So be careful with upcoming development.
As far as enabling proxies in the app and not the command line I believe you'll have to write a native module and use the V8::SetFlagsFromString
method (https://github.com/v8/v8/blob/f281162/include/v8.h#L4341-L4344). If you need an example I might make time to whip one up.
