FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package kyew
Kyew
Kyew is a thin layer on top of your existing queue package allowing you to push tasks to the queue and await the task completing.
Some examples where this could be useful include:
- Executing multiple tasks concurrently
- Pushing resource intensive tasks to a more performant server
Requirements
- PHP7.0+
- A queue package (see supported queues packages)
Example
Await a single task
Execute multiple tasks simultaneously
How it Works
When tasks are passed to $task = $kyew->async($task), they are immediately handed off to the underlying queue package, along with an additional instruction to then store the task return value back into a persistance layer (eg. a database).
On calling $task->await(), we simply sit in a loop until either that value appears in the persistance layer, or until we reach the timeout threshold.
Installation
Kyew can be installed with Composer
Kyew has two dependencies:
- A queue driver which implements the
Kyew\Queueinterface); used to hand jobs to your queue - A pub-sub driver which implements the
Kyew\PubSubinterface; used to pass data between processes
The below example uses the InMemoryPubSub and SynchronousQueue queue - you should use implementations which suit your environment.
API
Kyew::async(callable $task): Task
async accepts a single callable as its only parameter and will return an instance of Task.
The callable is immediately handed to the queue library to be executed. The Task instance will listen to the queue process and be notified when the callable has finished executing.
Task::await(): void
await will block further code execution until the given Task has completed exectuing.
Supported Queue Packages
IlluminateQueue: Execute tasks in Laravel's (Illuminate) queue packageSynchronousQueue: Execute tasks synchronously in the current process, mostly only used for testing
Supported persistence layers
DatabasePubSub: Store task return values in aPDOcompatible SQL databaseRedisPubSub: Store task return values in a redis serverInMemoryPubSub: Store task return values in an in-memory PHP array, mostly only used for testing
