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 announce
Announce
A simple framework agnostic PSR-14 event dispatcher for your event-driven application.
Features
- Uses PHP's
#Attributefeature to register class methods as event handlers - Optional PSR-11 Container support
- Full autowiring support for your subscribers and listeners - pass in not just the event but any needed services or other dependencies!
Installation
Quick start
Create an event class
Your events can be standalone classes or they can extend the StoppableEvent abstract class. By extending the StoppableEvent abstract you gain the ability to stop event propogation if needed.
Create a subscriber
Subscribers are classes that will handle your events. You can have as many subscribers as you would like.
To register a subscriber's method to handle a particular event or set of events, use the Nimbly\Announce\Subscribe attribute and pass in a comma separated list of event names to listen for.
Initiate Dispatcher
To register your subscriber's with the event dispatcher, pass in an array of class names or instances into the Dispatcher constructor.
You can also pass in a PSR-11 compliant container instance to be used in autowiring your subscribers as well as for event handlers on your subscribers.
Dispatch event
To trigger an event, just call the dispatch method with the event instance.
Stopping event propagation
If you need to stop event propagation during its lifetime, just call the stop() method on the event instance. The event will no longer be propagated to any further subscribed listeners. This requires the event to extend from the StoppableEvent abstract.
Registering individual listeners
Alternatively, you can register individual events using the listen method.
Wildcard listeners
You can register a "wild card" listener by using the * event name. This will subscribe to all events fired.
