NAME

JSON::RPC2 - Transport-independent implementation of json-rpc 2.0

SYNOPSIS

See JSON::RPC2::Server and JSON::RPC2::Client for usage examples.

DESCRIPTION

This module implement json-rpc 2.0 protocol in transport-independent way. It was very surprising for me to find on CPAN a lot of transport-dependent implementations of (by nature) transport-independent protocol!

Also it support non-blocking client remote procedure call and both blocking and non-blocking server method execution. This can be very useful in case server methods will need to do some RPC or other slow things like network I/O, which can be done in parallel with executing other server methods in any event-based environment.

INTERFACE

See JSON::RPC2::Server and JSON::RPC2::Client for details.

RATIONALE

There a lot of other RPC modules on CPAN, most of them has features doesn't provided by this module, but they either too complex and bloated or lack some features I need.

RPC::Lite

Not transport-independent.

RPC::Simple

Not transport-independent. Do eval() of perl code received from remote server.

RPC::Async

Not transport-independent. Not event-loop-independent.

JSON::RPC
RPC::JSON
RPC::Object
Event::RPC
RPC::Serialized
XML::RPC
RPC::XML

Not transport-independent. Blocking on remote function call.

JSON::RPC::Common

In theory it's doing everything... but I failed to find out how to use it (current version is 0.05) - probably it's incomplete yet. Even now it's too complex and bloated for me, I prefer small and simple solutions.

DIAGNOSTICS

None.

CONFIGURATION AND ENVIRONMENT
