Choose your own router; we support: - [FastRoute](https://github.com/nikic/FastRoute) - [laminas-router](https://github.com/mezzio/mezzio-router) - DI Containers, via [PSR-11 Container](https://github.com/php-fig/container). Middleware matched via routing is retrieved from the composed container. - Optionally, templating. We support: - [Plates](http://platesphp.com/) - [Twig](https://twig.symfony.com/) - [Laminas's PhpRenderer](https://github.com/laminas/laminas-view) Installation ------------ [](#installation) We provide two ways to install Mezzio, both using [Composer](https://getcomposer.org): via our [skeleton project and installer](https://github.com/mezzio/mezzio-skeleton), or manually. ### Using the skeleton + installer [](#using-the-skeleton--installer) The simplest way to install and get started is using the skeleton project, which includes installer scripts for choosing a router, dependency injection container, and optionally a template renderer and/or error handler. The skeleton also provides configuration for officially supported dependencies. To use the skeleton, use Composer's `create-project` command: ``` composer create-project mezzio/mezzio-skeleton ``` This will prompt you through choosing your dependencies, and then create and install the project in the `` (omitting the `` will create and install in a `mezzio-skeleton/` directory). ### Manual Composer installation [](#manual-composer-installation) You can install Mezzio standalone using Composer: ``` composer require mezzio/mezzio ``` However, at this point, Mezzio is not usable, as you need to supply minimally: - a router. - a dependency injection container. We currently support and provide the following routing integrations: - [FastRoute](https://github.com/nikic/FastRoute): `composer require mezzio/mezzio-fastroute` - [laminas-router](https://github.com/mezzio/mezzio-router): `composer require mezzio/mezzio-laminasrouter` We recommend using a dependency injection container, and typehint against [PSR-11 Container](https://github.com/php-fig/container). We can recommend the following implementations: - [laminas-servicemanager](https://github.com/laminas/laminas-servicemanager): `composer require laminas/laminas-servicemanager` - [Pimple](https://github.com/silexphp/Pimple) (see [docs](docs/book/features/container/pimple.md) for more details): `composer require laminas/laminas-pimple-config` - [Aura.Di](https://github.com/auraphp/Aura.Di) (see [docs](docs/book/features/container/aura-di.md) for more details): `composer require laminas/laminas-auradi-config` Additionally, you may optionally want to install a template renderer implementation, and/or an error handling integration. These are covered in the documentation. Documentation ------------- [](#documentation) Documentation is [in the doc tree](docs/book/), and can be compiled using [mkdocs](https://www.mkdocs.org): ``` mkdocs build ``` Additionally, public-facing, browseable documentation is available at ### Health Score 74 — ExcellentBetter than 100% of packages Maintenance82 Actively maintained with recent releases Popularity63 Solid adoption and visibility Community49 Growing community involvement Maturity92 Battle-tested with a long release history Bus Factor1 Top contributor holds 64.5% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
