# NAME

JSON::RPC::Spec - Yet another JSON-RPC 2.0 Implementation

# SYNOPSIS

   use strict;
   use JSON::RPC::Spec;

   my $rpc = JSON::RPC::Spec->new;

   # server
   $rpc->register(echo => sub { $_[0] });
   print $rpc->parse(
       '{"jsonrpc": "2.0", "method": "echo", "params": "Hello, World!", "id": 1}'
   );    # -> {"jsonrpc":"2.0","result":"Hello, World!","id":1}

   # client
   print $rpc->compose(echo => 'Hello, World!', 1);
     # -> {"jsonrpc":"2.0","method":"echo","params":"Hello, World!","id":1}

# DESCRIPTION

JSON::RPC::Spec is Yet another JSON-RPC 2.0 Implementation.

JSON format string execute registered method.

JSON::RPC - PSGI

The tightly also supports BATCH.

As a feature.
1\. JSON string to JSON string.
2\. Simple register callback.

# FUNCTIONS

## new

constructor.

options ["coder" in JSON::RPC::Spec::Common](https://metacpan.org/pod/JSON::RPC::Spec::Common#coder) and ["router"](#router) are available.

## register

   # method => code refs
   use List::Util qw(max);
   $rpc->register(max => sub { max(@{$_[0]}) });

   # method matching via Router::Simple
   $rpc->register('myapp.{action}' => sub {
       my ($params, $match) = @_;
       my $action = $match->{action};
       return MyApp->new->$action($params);
   });

register method.

## parse

   my $result = $rpc->parse(
       '{"jsonrpc": "2.0", "method": "max", "params": [9,4,11,0], "id": 1}'
   );    # returns JSON encoded string -> {"id":1,"result":11,"jsonrpc":"2.0"}

parse JSON and triggered method. returns JSON encoded string.

## parse\_without\_encode

   my $result = $rpc->parse_without_encode(
       '{"jsonrpc": "2.0", "method": "max", "params": [9,4,11,0], "id": 1}'
   );    # returns hash -> {id => 1, result => 11, jsonrpc => '2.0'}

parse JSON and triggered method. returns HASH.

## compose

See ["compose" in JSON::RPC::Spec::Client](https://metacpan.org/pod/JSON::RPC::Spec::Client#compose) for full documentation.

## router

similar [Router::Simple](https://metacpan.org/pod/Router::Simple).

# DEBUGGING

You can set the `PERL_JSON_RPC_SPEC_DEBUG` environment variable to get some advanced diagnostics information printed to `STDERR`.
