RMQC provide to work with RabbitMQ without complexity. RMQC uses AMQP framework in background and does not reflect the complexity that comes with AMQP to the developer.
Via go packages:
go get github.com/rozturac/rmqc
Hint: Check the go-ddd-example project, the project have rmqc integration with consumers and publisher.
Here is a sample RabbitMQ initialization:
import (
"github.com/rozturac/rmqc"
consumers "github.com/rozturac/rmqc/_examples/consumers"
"github.com/rozturac/rmqc/_examples/events"
)
func NewRabbitMQ() (*rmqc.RabbitMQ, error) {
return rmqc.Connect(rmqc.RabbitMQConfig{
Host: "localhost",
Username: "guest",
Password: "guest",
Port: "5672",
VHost: "/",
ConnectionName: "rabbitmq-test",
Reconnect: rmqc.Reconnect{
MaxAttempt: 5,
Interval: 100,
},
})
}The Event must be implemented from the IEvent interface.
type SimpleEvent struct {
Message string
}
func NewSimpleEvent(message string) *SimpleEvent {
return &SimpleEvent{Message: message}
}Queue and Exchange definitions to be made, consumers must first be configured.
//Implemented by rmqc.IConsumer
import (
"fmt"
"github.com/rozturac/rmqc"
"github.com/rozturac/rmqc/_examples/events"
)
type SimpleConsumer struct {
}
func NewSimpleConsumer() *SimpleConsumer {
return &SimpleConsumer{}
}
func (s SimpleConsumer) Configure(builder *rmqc.ConsumerBuilder) {
builder.BindQueue("rabbitmq-test-queue")
builder.SubscribeAsDirect("rabbitmq-test-exchange", "1")
builder.SetConsumerName("SimpleConsumer")
builder.SetPrefetchCount(4)
builder.SetConsumerCount(4)
}
func (s SimpleConsumer) Consume(context *rmqc.ConsumerContext) {
var event events.SimpleEvent
context.Unmarshal(&event)
fmt.Println(event)
}rbt := NewRabbitMQ()
consumer := consumers.NewSimpleConsumer()
if err = rbt.BindConsumer(consumer); err != nil {
panic(err)
}
rbt.Start()rbt := NewRabbitMQ()
event := events.NewSimpleEvent("Hello World!")
rbt.Publish("rabbitmq-test-exchange", "1", event)MIT License
