BackQ - Component

Background queue processing - publish tasks and process with workers, simplified.

• Sending APNS push notifications (Legacy API)
• Sending FCM push notifications to Android (GCM/FCM)
• Sending AWS SNS push notifications via AWS SNS arn's
• Executing Psr7\Request asynchronously via Guzzle
• Executing any processes with symfony/process
• Long delay scheduling via DynamoSQS Adapter and Serialized worker, for reliable long-term scheduled jobs
• Extendable - write your own worker and use existing adapters out of the box ...

Installation

#composer self-update && composer clear-cache && composer diagnose
composer require sshilko/backq:^3.0

Example with Redis adapter and process worker

#launch local redis
docker run -d --name=example-backq-redis --network=host redis

#install library in any folder for testing
mkdir /tmp/example && cd /tmp/example
composer require sshilko/backq:^3.0

#post job to queue (schedule)
cd vendor/sshilko/backq/example/publishers/process && php redis.php && cd /tmp/example

#[debug] connect
#[debug] _connect
#[debug] putTask
#[debug] putTask is connected and ready to: write
#[debug] putTask pushed task without delay xoOgPKcS9bIDVXSaLYH9aLB22gzzptRo
#[debug] putTask return 'xoOgPKcS9bIDVXSaLYH9aLB22gzzptRo'
#Published process message via redis adapter as ID=xoOgPKcS9bIDVXSaLYH9aLB22gzzptRo

#fetch job from queue (work)
cd vendor/sshilko/backq/example/workers/process && php redis.php && cd /tmp/example

#[debug] Disconnecting
#[debug] Disconnecting, previously connected
#[debug] Disconnecting, state detected
#[debug] Disconnecting, state detected, queue is connected
#[debug] Disconnecting, state 0 jobs reserved and not finalized
#[debug] Disconnecting, state detected, disconnecting queue manager
#[debug] Disconnecting, successful

#verify job executed (example process worker does echo $( date +%s ) >> /tmp/test) 
cat /tmp/test
