If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

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 PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • 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.

Informations about the package laravel-with-db-transactions

waska14/laravel-with-db-transactions

Are you tired of writing database transactions for every controller method?

This package solves the problem with middleware.

Middleware begins database transaction and depending response (and config also) commits/rollbacks it.

Docs

Installation

Add the package in your composer.json by executing the command.

For Laravel versions before 5.5 or if not using auto-discovery, register the service provider in config/app.php

Configuration

If you want to change default configuration, you must publish default configuration file to your project by running this command in console:

This command will copy file [/vendor/waska14/laravel-with-db-transactions/config/waska.with_db_transactions.php] to [/config/waska.with_db_transactions.php]

Default waska.with_db_transactions.php looks like:

You can manage route middleware globally (automatically) from config:

Key Value(s) Comment
middleware_groups Keys of protected $middlewareGroups from app/Http/Kernel.php. Every route having the group middleware will be processed with database transaction.
ignore_request_methods HTTP request methods names (GET/HEAD) Those methods won'be processed with database transaction.
ignore_route_names route names Those methods also won't be processed with database transaction.
commit_http_statuses HTTP status codes If transaction has begun and the response has any of those statuses, the transaction will be committed.
maximum_attempts integer Maybe if deadlocks occurs or something else

If you want manually management, you can use middleware_alias (or change it, also) as route middleware.

Manual usage

If you define middleware_groups as an empty array in config, none of the routes will be processed with database transactions by default, until you set manually the middleware for the specific routes/route groups.

Note that you can fill middleware_groups and also use middleware manually anywhere you want the method to be processed with database transaction.

Default middleware alias is with_db_transactions which can be changed in config, also.

Note that all configuration (ignore_route_names, ignore_request_methods, maximum_attempts, commit_http_statuses etc.) will also work when using this package manually.

Actions and Events

After version 2.0.0 you can define closures that will be executed before/after commit/rollback(s).

After version 2.0.0 package dispatches events also.

You can listen them and do whatever you want in listener.
