sqs client

wtf is it?

a very very very simple sqs client package in go

---

usage

configs

type Config struct {
	ID       string //<< aws account id
	Key      string //<< aws auth key - leave blank for no auth
	Secret   string //<< aws account secret - leave blank for no auth
	Region   string //<< aws region
	Queue    string //<< queue name - not needed if url provided
	URL      string //<< queue url - not needed if queue provided
	Endpoint string //<< aws endpoint
	Retries  int    //<< max retries
	Timeout  int    //<< visibility timeout (seconds)
	Wait     int    //<< wait time (seconds)
}

new client

cli, err := sqsc.New(&sqsc.Config{
    ...
})

produce a message

id, err := cli.Produce("my cool message", del)

• del - the delay for the message (just use 0)
• id - the message id
• err - any error

consume a message

bod, rh, err := cli.Consume()

• bod - the message body
• rh - the receipt handle (use for deleting message)
• err - any error

note: if bod == "" && rh == "" && err == nil then the queue is empty, or no messages are visible

delete a message

res, err = cli.Delete(rh)

• rh - the receipt handle (from cli.Consume())
• res - the delete response (empty if successful)
• err - any error

example

package main

import (
	"fmt"
	"github.com/vestiaire-collective/sqsc"
	"os"
)

func main() {
	bod := os.Args[1]

	cli, err := sqsc.New(&sqsc.Config{
		Region:   "us-east-1",
		URL:      "http://localhost:4100/queue/job",
		Endpoint: "http://127.0.0.1:4100",
	})

	res, err := cli.Produce(bod, 0)

	fmt.Printf("produce response: %+v\n", res)
	fmt.Printf("produce error:    %+v\n", err)

	res, rh, err := cli.Consume()

	fmt.Printf("consume response:       %+v\n", res)
	fmt.Printf("consume receipt handle: %+v\n", rh)
	fmt.Printf("consume error:          %+v\n", err)

	res, err = cli.Delete(rh)

	fmt.Printf("delete response: %+v\n", res)
	fmt.Printf("delete error:    %+v\n", err)
}

• this is a super simple client, intentionally
