It provides a robust mechanism for processing HTTP requests through a chain of middleware components compliant with PSR-7 and PSR-15 standards. Overview -------- [](#overview) Bermuda Pipeline enables you to create a processing pipeline where each middleware receives a ServerRequest, performs its specific handling, and then delegates control to the next middleware in the chain. When the middleware chain is exhausted, a fallback handler is used to generate a response. The key benefits of using Bermuda Pipeline include: - **Immutability**: Methods such as `pipe()` return a new pipeline instance with the added middleware, keeping the original pipeline unchanged. This makes it safe for use in complex, multi-threaded, or reentrant scenarios. - **PSR Compliance**: The implementation is based on PSR-7 and PSR-15 standards, ensuring seamless interoperability with other components in the PHP ecosystem. - **Deep Cloning**: When cloning a pipeline, each middleware is deeply cloned to avoid shared mutable state, ensuring that changes to one instance do not affect others. - **Flexible Fallback Handler**: A fallback handler is invoked once all middleware have been executed, ensuring that a default response is always available. Features -------- [](#features) - **IteratorAggregate and Countable Interfaces**: Easily iterate over the middleware chain and retrieve the number of middleware components. - **Immutability**: The pipeline is designed to be immutable; all modifications (e.g., adding middleware) return a new instance. - **Deep Cloning**: When a pipeline is cloned, every middleware is cloned as well to prevent shared state issues. - **Factory Method**: The static method `createFromIterable()` simplifies the instantiation of a pipeline from a list of middleware components. - **Customizable Fallback Handler**: Use `withFallbackHandler()` to replace the default fallback handler without altering the original pipeline instance. Requires -------- [](#requires) - **PHP:** >= 8.4 Installation ------------ [](#installation) You can install Bermuda Pipeline via Composer. Run the following command in your project directory: ``` composer require bermudaphp/pipeline ``` Usage ----- [](#usage) ``` // Create the pipeline with an array of middleware $pipeline = new Pipeline([new MyFirstMiddleware(), new MySecondMiddleware]); // Process the request through the pipeline, resulting in a ResponseInterface instance $response = $pipeline->handle($request); ``` ### Health Score 46 — FairBetter than 93% of packages Maintenance66 Regular maintenance activity Popularity14 Limited adoption so far Community9 Small or concentrated contributor base Maturity79 Established project with proven stability Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
