MojoX::Redis - asynchronous Redis client for Mojolicious.
use MojoX::Redis; my $redis = MojoX::Redis->new(server => '127.0.0.1:6379'); # Execute some commands $redis->ping( sub { my ($redis, $res) = @_; if ($res) { print "Got result: ", $res->[0], "\n"; } else { print "Error: ", $redis->error, "\n"; } } ); # Work with keys $redis->set(key => 'value'); $redis->get( key => sub { my ($redis, $res) = @_; print "Value of 'key' is $res->[0]\n"; } ); # Cleanup connection $redis->quit(sub { shift->stop }); # Start IOLoop (in case it is not started yet) $redis->start;
Create new Mojo::IOLoop instance if you need to get blocked in a Mojolicious application.
use Mojolicious::Lite; use MojoX::Redis; get '/' => sub { my $self = shift; my $redis = MojoX::Redis->new(ioloop => Mojo::IOLoop->new); my $value; $redis->set(foo => 'bar')->get( foo => sub { my ($redis, $result) = @_; $redis->quit->stop; return app->log->error($redis->error) unless $result; $value = $result->[0]; } )->start; $self->render(text => qq(Foo value is "$value")); }; app->start;
MojoX::Redis is an asynchronous client to Redis for Mojo.
MojoX::Redis implements the following attributes.
server
my $server = $redis->server; $redis = $redis->server('127.0.0.1:6379');
Redis server connection string, defaults to '127.0.0.1:6379'.
Redis
ioloop
my $ioloop = $redis->ioloop; $redis = $redis->ioloop(Mojo::IOLoop->new);
Loop object to use for io operations, by default a Mojo::IOLoop singleton object will be used.
timeout
my $timeout = $redis->timeout; $redis = $redis->timeout(100);
Maximum amount of time in seconds a connection can be inactive before being dropped, defaults to 300.
300
encoding
my $encoding = $redis->encoding; $redis = $redis->encoding('UTF-8');
Encoding used for stored data, defaults to UTF-8.
UTF-8
protocol_redis
use Protocol::Redis::XS; $redis->protocol_redis("Protocol::Redis::XS");
Protocol::Redis implementation' constructor for parsing. By default Protocol::Redis will be used. Parser library must support APIv1.
Using Protocol::Redis::XS instead of default choice can speedup parsing.
MojoX::Redis supports Redis' methods.
$redis->set(key => 'value); $redis->get(key => sub { ... });
For more details take a look at execute method.
execute
Also MojoX::Redis implements the following ones.
connect
$redis = $redis->connect;
Connect to Redis server.
$redis = $redis->execute("ping" => sub{ my ($redis, $result) = @_; # Process result }); $redis->execute(lrange => ["test", 0, -1] => sub {...}); $redis->execute(set => [test => "test_ok"]);
Execute specified command on Redis server. If error occured during request $result will be set to undef, error string can be obtained with $redis->error.
error
$redis->execute("ping" => sub { my ($redis, $result) = @_; die $redis->error unless defined $result; });
Returns error occured during command execution. Note that this method returns error code just from current command and can be used just in callback.
on_error
$redis->on_error(sub{ my $redis = shift; warn 'Redis error ', $redis->error, "\n"; });
Executes if error occured. Called before commands callbacks.
start
$redis->start;
Starts IOLoop. Shortcut for $redis->ioloop->start;
