Simply Observe - Newton allows you to Subscribe and Listen for Event Broadcasts in the [Codeigniter](https://codeigniter.com/) framework.
## Installation
```bash
composer require tfhinc/ci-newton
```
Run the post install `publish-files` command to publish the config, helper and library class files to the appropriate CI directories:
```bash
composer --working-dir=vendor/tfhinc/ci-newton/ run-script publish-files
```
## Loading the Library
There are a few available options for loading the Newton library:
### Using the `newton()` helper function
The Newton helper function will resolve the Newton class via the CI instance. It will either load the class or return the existing class instance:
``` php
$this->load->helper('newton');
```
### Using the Newton Class
The Newton class can be instantiated via namespace:
``` php
$newton = new TFHInc/Newton/Newton();
```
### Using the Newton CI Library
The Newton class can be loaded like any other CI library:
``` php
$this->load->library('Newton');
```
## Class Structure
The Newton library allows for `Listener` classes to subscribe to `Event` class broadcasts. This helps decouple your business logic into single purpose `Listener` classes that can be invoked en masse by the broadcast of an `Event`.
### Event Classes
The `Event` class defines the properties that a given event will require and receive where there is a broadcast. The `Event` class does not contain any business logic - think of it as a blueprint of required data for a given event.
*application/events/UserCreatedEvent.php*
``` php
email = $email;
$this->first_name = $first_name;
$this->last_name = $last_name;
}
}
```
### Listener Classes
The `Listener` class contains the business logic that will be performed when a subscribed `Event` is broadcast. The `Listener` class will receive an instance of the `Event` class, which includes the event properties for usage in your business logic:
Note that the `Listener` class must extend the `TFHInc/Newton/NewtonListener` abstract class.
*application/listeners/SendAdminEmailListener.php*
``` php
email . ' just signed up!');
}
}
```
*application/listeners/UpdateUserStatsListener.php*
```php
[
'Listeners\SendAdminEmailListener',
'Listeners\UpdateUserStatsListener'
]
];
```
### Via Subscribe Method
```php
newton()->subscribe('Events\UserCreatedEvent', [
'Listeners\SendAdminEmailListener',
'Listeners\UpdateUserStatsListener'
]);
```
## Broadcasting Events
An `Event` can be broadcast via the `broadcast()` method using the Newton library or `newton()` helper function:
``` php
// Broadcast an Event to all Subscribed Listeners via Newton helper
newton()->broadcast('UserCreatedEvent', '[email protected]', 'Bob', 'Belcher');
// Broadcast an Event to all Subscribed Listeners via Newton class
$newton->broadcast('UserCreatedEvent', '[email protected]', 'Bob', 'Belcher');
```
In this example the `UserCreatedEvent` class will be instantiated and in turn,
instantiate the subscribed classes `SendAdminEmailListener` and `UpdateUserStatsListener`.
