nikolag/core

Core package for building additional payment gateway integrations with nikolag packages and Laravel >=5.5

Installation guide

composer require nikolag/core

Usage

This package contains all of the necessary code to get you started with building the additional integrations of payment gateways with nikolag packages. First of all there are couple of important layers and structure that you must follow:

1. Configuration file
2. Main service
3. Dependency Injections
4. Migrations and Factories
5. Facades
6. Models
7. Providers
8. Traits
9. Tests
10. Utility classes

1. Configuration file

Configuration file is the most important here since it'll contain all of the required pre-set options of your library. The file must be called nikolag.php and it must be inside of src/config folder.

This is just a starter snippet which u can start adapting to your own library. There are couple of important variables that u gotta change and rules which you must follow. Change {$default} with the name of your package (paypal, payeer, payoneer, ...) and also include the fully qualified name (namespace) of your service instead of {$namespace}. You can check nikolag.php example of how config file should look like. SquareConfig.php is the example of how your configuration class should look like.

2. Main service

Your package must have at least 1 main service which is responsible for all communication between rest calls and your package. It also must extend Nikolag\Core\Abstracts\CorePaymentService and it must implement Nikolag\Core\Contracts\PaymentServiceContract thats explained in the next step. Example of that kind of class can be found SquareService.php.

3. Dependency Injections

Your library must have at least 1 contract which should be named {$serviceName}ServiceContract.php where {$serviceName} is the name of service you are trying to integrate with nikolag packages and Laravel Also it must extends Nikolag\Core\Contracts\PaymentServiceContract. Any other contract which is not connected with your service file in any way mustn't extend the above contract. Some examples of such name are PaypalServiceContract.php, PayeerServiceContract.php, PayoneerServiceContract.php. Example of the contract can be found SquareContract.php.

4. Migrations and Factories

All migrations and factories must be under src/database folder and each of them respectively will have it's own subfolder src/database/factories and src/database/migrations. This core package already has couple of migrations so you don't have to write them yourself, but you can extend on them if necessary.

5. Facades

All facades are found under src/facades and your package must have at least 1 facade which must be alias for your main service class.

6. Models

All models must be located under src/models. There are 2 core models: Customer and Transaction.

You must extend those 2 core models and create your own from them with all relationships available and also add

The above is only required for 2 base models, any other models u might make don't have to extend anything and you can create them normally. Example can be found Customer.php.

7. Providers

You can register multiple providers and they should be named respectively for their role in the library. You can find them under src/providers folder. Here are some examples: ExceptionServiceProvider, MyServiceProvider, ExternalLibrariesProvider, etc..

8. Traits

All traits must be under src/traits.

9. Tests

All your tests must be under tests and they are split into 2 types: integration and unit where each of them has it's own subfolder.

10. Utility classes

All your utility classes must be under src/utils folder.

All available core methods
