Transaction Middleware for Laravel

Transaction Middleware for Laravel is a simple package that provides a middleware to wrap DELETE requests in a database transaction. This means that if an error occurs during a DELETE request, any database changes will be rolled back automatically, ensuring data integrity.

Version: 1.0.6

Features

• DB Transaction on DELETE Requests: Wraps only DELETE method requests in a database transaction. If an exception is thrown during request processing, the transaction is rolled back.

• Flexible Auto-application: Control how the middleware is applied via configuration:

  • auto_apply_global — Apply automatically to global middleware.
  • auto_apply_web — Apply automatically to the web group only.
  • auto_apply_api — Apply automatically to the api group only.

• Manual Attachment: Even if you choose not to auto-apply, the middleware is available via its alias (transaction) for manual attachment on routes.

• Laravel Auto-Discovery: The package uses Laravel’s auto-discovery so you don’t need to manually register the service provider.

Requirements

• PHP ^8.0
• Laravel 9.x, 10.x, 11.x or 12.x (or higher)

Installation

Install via Composer:

Laravel will automatically discover the service provider. If you need to publish the configuration file, run:

This will copy the configuration file to your Laravel application’s config directory as transaction-middleware.php.

Configuration

The published config file (config/transaction-middleware.php) looks like this:

How It Works

• Auto-application Mode: If you set auto_apply_web_api to true, the service provider will automatically push the middleware to both the web and api middleware groups.

• Selective Auto-application: Alternatively, you can set only one of the other two options (auto_apply_web or auto_apply_api) to true to have the middleware applied only to that particular group.

• Manual Mode: With all auto-apply options set to false, you must manually attach the middleware to your routes using the alias transaction.

Usage

1. Automatic Middleware Application

After publishing the config file, edit it as needed:

• To add the middleware to both groups:

• To add it only to the web group:

• To add it only to the API group:

In these modes, you don’t need to add the middleware manually; it will automatically be pushed into the appropriate middleware groups.

2. Manual Middleware Application

If you prefer to control where the middleware is applied, leave all auto-apply options as false. Then, attach the middleware to your routes like so:

3. Transaction Trait

The easiest will be to use the \Azmolla\TransactionMiddleware\Traits\HasTransactionCalls trait which adds a transaction() method.

Transaction chained Method

You can call the transaction() without any argument and the method after will be called in a transaction.

This example will call the delete() method in a transaction. This is useful if you have any listeners also running database queries, like deleting child models. The transaction will prevent you from corrupted data if any of the queries fails.

Conditional Callback

If you want you can also pass a callback to the transaction() method you will get the calling object as first argument.

How It Works Under the Hood

• Middleware Logic: The middleware checks if the request is a DELETE method. If so, it starts a DB transaction using DB::beginTransaction(). The request is then passed along the middleware pipeline. If the request processing completes without error, DB::commit() is called. In case of an exception, DB::rollBack() is executed, and the exception is rethrown.

• Service Provider: The TransactionMiddlewareServiceProvider merges your package’s configuration with the application config, publishes the config file for customization, and conditionally pushes the middleware into the appropriate groups based on the configuration values.

• Laravel Auto-discovery: Thanks to the extra block in the composer.json, Laravel auto-discovers and registers the service provider, so there’s no manual configuration required in config/app.php.

• Trait Usage: You can use the \Azmolla\TransactionMiddleware\Traits\HasTransactionCalls trait to add a transaction() method to your models.
