Laratasks

Demonstrates laravel queues and demonstrates a notification and reminder system

Notes from links:

In .env

Replace this line.

QUEUE_CONNECTION=sync

With this line.

QUEUE_CONNECTION=database

Queues

• multiple queues allowed with multiple names, different queues can have different priorities
• config @ config/queue.php
• Make Queue table: php artisan queue:table, php artisan migrate
• Start Queue: php artisan queue:work

Jobs

• stored in app/Jobs
• php artisan make:job [jobName]
• [jobName]::dispatch([$params]) , also dispatchIf/dispatchUnless
• can delay, ex.: ->delay(now()->addMinute())
• can chain jobs
• can change max attempts, ex.: php artisan queue:work --tries=3 or right inside job: public $tries = X
• job processing goes inside handle() function

Failed Jobs

• Make failed jobs table: php artisan queue:failed-table, php artisan migrate

  Schedules

• inside schedule() method of App\Console\Kernel class Can run artisan commands, ex.: $schedule->command('migrate:refresh --seed')->daily();
• lots of time constraints available
• to run locally: php artisan schedule:work

• use cron to run on production machine

  Mail

• make email: php artisan make:mail [mailName] --markdown=emails.etc

Other tips:

• Log::info('this is logged')

Notifications:

• use the 'Notifiable' trait on models to notify, added to user model by default
• various channels: mail, slack nexmo (SMS)
• add implements shouldQueue after making a notification with make:notification
• to notify: $user->notify(new Notification())
• notify non user: Notification::route('mail', 'email@email.com')->route(etc...)->notify(new Notification())
• make notifications table: php artisan notifications:table - see gotchas (4)

1. Set default queue to 'database' not sync

To add to the priority queue: dispatch((new Job)->onQueue('priority')); * see gotchas (1)

Run this worker for this project with Supervisor/CRON:

• php artisan queue:work --queue=priority,default --tries=2 -> runs priority queue items first, allows 2 attempts before failing

• can run this line locally for development

Twilio (https://github.com/laravel-notification-channels/twilio): composer require laravel-notification-channels/twilio

Enter in .env: TWILIO_ACCOUNT_SID= TWILIO_AUTH_TOKEN= TWILIO_DEBUG_TO= TWILIO_FROM=

php artisan vendor:publish --provider="NotificationChannels\Twilio\TwilioProvider"

Gotchas

1. secondary queues are not created in the config file, you can essentially dispatch to any string you want as long as the worker knows to look for it
2. dd() inside an item being processed by the queue worker is displayed inside the terminal
3. DON'T make a custom notifications table like I tried, laravel makes one itself
4. If Queue code is changed, the queue will need to be rerun or it will continue using the old code
