README
in many projects, you need to have credit (balance) concept for your user that make you distract from your main business logic.
with this package you will have balance for your users easily without being worry about Race Condition
and Double Spending
.
this project mainly designed for exchange systems, but you can use it in any project.
Installation
composer require roboticsexpert/balance-manager
after instaling composer package, if you use auto discovery for service providers, everything ok, but if you blocked
that just add this line to config/app.php
in providers
section:
Roboticsexpert\BalanceManager\BalanceManagerServiceProvider::class
after that you should run
php artisan migrate
and this:
php artisan vendor:publish --provider="Roboticsexpert\BalanceManager\BalanceManagerServiceProvider"
it will create balance.php
file in your config file.
Usage
First of all, you should decide with currencies you want to have in your system, and consider a KEY for each currency and add those keys in balance.php config file
return [ // add symbols of your currencies // symbols must be lower than 16 char 'currencies'=>[ 'BTC', 'TMN', 'DOGE', ] ];
you can use this project with 2 strategy,Facade or Dependency injection!
I suggest to you to use it with dependecy injection for IDE auto complete feature but use it as you prefer!
after that you can get BalanceManager
from with these to methods:
Facade
you can get BalanceManager service like this:
use Roboticsexpert\BalanceManager\BalanceManagerFacade as BalanceManager; BalanceManager::getAllBalancesByUserId(1)
Dependency Injection
you can get BalanceManager service from app()
like this:
use Roboticsexpert\BalanceManager\Services\BalanceManager; $balanceManager=app(BalanceManager::class); $balanceManager->getAllBalancesByUserId(1);
or get from laravel automatic dependency injection
use Roboticsexpert\BalanceManager\Services\BalanceManager; class Controller extends BaseController { use AuthorizesRequests, DispatchesJobs, ValidatesRequests; public function index(BalanceManager $balanceManager){ dd($balanceManager->getAllBalancesByUserId(1)); } }
Methods

model
$balances= $balanceManager->getAllBalancesByUserId("USER_ID"); dd($balances);
Change balance of user
$balanceChangeResult= $balanceManager->changeBalanceByUserIdAndCurrency( int $userId, //user id string $currency, // like USDT, TMN string $reason, // a unique string for each action IBalanceHistoryRelated $model, // a model that is author of change balance Decimal $valueChange, // value you want to add or sub from user balance Decimal $lockedValueChange // in general usage it should be new \Decimal\Decimal(0) );
