Welcome
-------

[](#welcome)

TheWebSolver Pipeline library follows the 🔗 Chain of Responsibility Design Pattern 🔗 to handle the given subject/request using pipes. The pipeline can accept any subject type, passes it through provided pipes and return the updated subject back.

Installation (via Composer)
---------------------------

[](#installation-via-composer)

Install library using composer command:

```
$ composer require thewebsolver/pipeline
```

Benefits
--------

[](#benefits)

- Follows Chain of Responsibility design pattern by passing subject to pipeline handlers in order they were stacked.

    > Use *`Pipeline::through()`* method to pass main handlers as pipe. Optionally, pass additional handlers using *`Pipeline::pipe()`* method.
- Provides support for additional arguments that can be accepted by each handler passed using above methods.

    > Use *`Pipeline::use()`* method to pass as many arguments as required.
- Provides support for catching [Pipe Exception](Src/InvalidPipeError.php) or [Unexpected Exception](Src/UnexpectedPipelineException.php) thrown by the handler.

    > Use *`Pipeline::sealWith()`* method to pass a closure to handle thrown exception.
- Provides [bridge](Server/Bridge.php) for PHP Projects that implements [PSR-7](https://www.php-fig.org/psr/psr-7/) & [PSR-15](https://www.php-fig.org/psr/psr-15/) standards.

    > Use [Queue based Request Handler](https://www.php-fig.org/psr/psr-15/meta/#queue-based-request-handler) implementation to handle stacked middlewares inside [Request Handler](https://www.php-fig.org/psr/psr-15/#21-psrhttpserverrequesthandlerinterface)'s handle method (*`RequestHandlerInterface::handle()`*).
