Adding the error handler

• Add the composer package:

composer require dotkernel/dot-errorhandler

• Add the config provider:
  • in config/config.php add \Dot\ErrorHandler\ConfigProvider
  • in config/pipeline.php add \Dot\ErrorHandler\ErrorHandlerInterface::class
    • the interface is used as an alias to keep all error handling related configurations in one file

If you need other error handlers, you should place them before dot-errorhandler in the pipeline; else it will not be able to catch errors. We recommend using just one error handler unless you have an error-specific handler.

• Configure the error handler as shown below.

In config/autoload/error-handling.global.php:

<?php

use Dot\ErrorHandler\ErrorHandlerInterface;
use Dot\ErrorHandler\LogErrorHandler;
use Dot\ErrorHandler\ErrorHandler;

return [
    'dependencies' => [
        'aliases' => [
            ErrorHandlerInterface::class => LogErrorHandler::class,
        ]

    ],
    'dot-errorhandler' => [
        'loggerEnabled' => true,
        'logger' => 'dot-log.default_logger'
    ]
];

A configuration example for the default logger can be found in config/log.global.php.dist.

When configuring the error handler in your application, you can choose between two classes:

• Dot\ErrorHandler\LogErrorHandler: for logging and displaying errors
• Dot\ErrorHandler\ErrorHandler: for displaying errors only

Both LogErrorHandler and ErrorHandler have factories declared in the package's ConfigProvider. If you need a custom ErrorHandler, it must have a factory declared in the config, as in the below example:

<?php

use Dot\ErrorHandler\ErrorHandlerInterface;
use Custom\MyErrorHandler;
use Custom\MyErrorHandlerFactory;

return [
    'dependencies' => [
        'factories' => [
            MyErrorHandler::class => MyCustomHandlerFactory::class,
        ],
        'aliases' => [
            ErrorHandlerInterface::class => MyErrorHandler::class,
        ]
    ],
    'dot-errorhandler' => [
        'loggerEnabled' => true,
        'logger' => 'dot-log.default_logger',
    ]
];

Config examples can be found in this project's config directory.
