go-rabbitmq
Wrapper of rabbitmq/amqp091-go that provides reconnection logic and sane defaults. Hit the project with a star if you find it useful ⭐
Supported by Qvault
Motivation
Streadway's AMQP library is currently the most robust and well-supported Go client I'm aware of. It's a fantastic option and I recommend starting there and seeing if it fulfills your needs. Their project has made an effort to stay within the scope of the AMQP protocol, as such, no reconnection logic and few ease-of-use abstractions are provided.
Goal
The goal with go-rabbitmq
is to still provide most all of the nitty-gritty functionality of AMQP, but to make it easier to work with via a higher-level API. Particularly:
- Automatic reconnection
- Multithreaded consumers via a handler function
- Reasonable defaults
- Flow control handling
⚙️ Installation
Inside a Go module:
go get github.com/wagslane/go-rabbitmq
🚀 Quick Start Consumer
Default options
consumer, err := rabbitmq.NewConsumer("amqp://user:pass@localhost", amqp.Config{})
if err != nil {
log.Fatal(err)
}
err = consumer.StartConsuming(
func(d rabbitmq.Delivery) rabbitmq.Action {
log.Printf("consumed: %v", string(d.Body))
// rabbitmq.Ack, rabbitmq.NackDiscard, rabbitmq.NackRequeue
return rabbitmq.Ack
},
"my_queue",
[]string{"routing_key1", "routing_key2"}
)
if err != nil {
log.Fatal(err)
}
With options
consumer, err := rabbitmq.NewConsumer(
"amqp://user:pass@localhost",
amqp091.Config{},
rabbitmq.WithConsumerOptionsLogging,
)
if err != nil {
log.Fatal(err)
}
err = consumer.StartConsuming(
func(d rabbitmq.Delivery) rabbitmq.Action {
log.Printf("consumed: %v", string(d.Body))
// rabbitmq.Ack, rabbitmq.NackDiscard, rabbitmq.NackRequeue
return rabbitmq.Ack
},
"my_queue",
[]string{"routing_key", "routing_key_2"},
rabbitmq.WithConsumeOptionsConcurrency(10),
rabbitmq.WithConsumeOptionsQueueDurable,
rabbitmq.WithConsumeOptionsQuorum,
rabbitmq.WithConsumeOptionsBindingExchangeName("events"),
rabbitmq.WithConsumeOptionsBindingExchangeKind("topic"),
rabbitmq.WithConsumeOptionsBindingExchangeDurable,
rabbitmq.WithConsumeOptionsConsumerName(consumerName),
)
if err != nil {
log.Fatal(err)
}
🚀 Quick Start Publisher
Default options
publisher, returns, err := rabbitmq.NewPublisher("amqp://user:pass@localhost", amqp091.Config{})
if err != nil {
log.Fatal(err)
}
err = publisher.Publish([]byte("hello, world"), []string{"routing_key"})
if err != nil {
log.Fatal(err)
}
With options
publisher, returns, err := rabbitmq.NewPublisher(
"amqp://user:pass@localhost",
amqp091.Config{},
// can pass nothing for no logging
rabbitmq.WithPublisherOptionsLogging,
)
if err != nil {
log.Fatal(err)
}
err = publisher.Publish(
[]byte("hello, world"),
[]string{"routing_key"},
rabbitmq.WithPublishOptionsContentType("application/json"),
rabbitmq.WithPublishOptionsMandatory,
rabbitmq.WithPublishOptionsPersistentDelivery,
rabbitmq.WithPublishOptionsExchange("events"),
)
if err != nil {
log.Fatal(err)
}
go func() {
for r := range returns {
log.Printf("message returned from server: %s", string(r.Body))
}
}()

Stability
Note that the API is currently in v0
. I don't plan on any huge changes, but there may be some small breaking changes before we hit v1
.
