Begin developing PSR-15 middleware applications in seconds!

mezzio builds on laminas-stratigility to provide a minimalist PSR-15 middleware framework for PHP with routing, DI container, optional templating, and optional error handling capabilities.

This installer will setup a skeleton application based on mezzio by choosing optional packages based on user input.

The user selected packages are saved into composer.json so that everyone else working on the project have the same packages installed. Configuration files and templates are prepared for first use. The installer command is removed from composer.json after setup succeeded, and all installer related files are removed.

Getting Started

Start your new Mezzio project with composer:

$ composer create-project mezzio/mezzio-skeleton <project-path>

After choosing and installing the packages you want, go to the <project-path> and start PHP's built-in web server to verify installation:

$ composer serve

You can then browse to http://localhost:8080.

Installing alternative packages

There is a feature to install alternative packages: Instead of entering one of the selection you can actually type the package name and version.

  Which template engine do you want to use?
  [1] Plates
  [2] zend-view installs zend-servicemanager
  [n] None of the above
  Make your selection or type a composer package name and version (n): infw/pug:0.1
  - Searching for infw/pug:0.1
  - Adding package infw/pug (0.1)

That feature allows you to install any alternative package you want. It has its limitations though:

• The alternative package must follow this format namespace/package:1.0. It needs the correct version.
• Templates are not copied, but the ConfigProvider can be configured in such way that it uses the default templates directly from the package itself.
• This doesn't work for containers as the container.php file needs to be copied.

Troubleshooting

If the installer fails during the composer create-project phase, please go through the following list before opening a new issue. Most issues we have seen so far can be solved by self-update and clear-cache.

1. Be sure to work with the latest version of composer by running composer self-update.
2. Try clearing Composer's cache by running composer clear-cache.

If neither of the above help, you might face more serious issues:

• Info about the zlib_decode error.
• Info and solutions for composer degraded mode.

Application Development Mode Tool

This skeleton comes with laminas-development-mode. It provides a composer script to allow you to enable and disable development mode.

To enable development mode

Note: Do NOT run development mode on your production server!

$ composer development-enable

Note: Enabling development mode will also clear your configuration cache, to allow safely updating dependencies and ensuring any new configuration is picked up by your application.

To disable development mode

$ composer development-disable

Development mode status

$ composer development-status

Configuration caching

By default, the skeleton will create a configuration cache in data/config-cache.php. When in development mode, the configuration cache is disabled, and switching in and out of development mode will remove the configuration cache.

You may need to clear the configuration cache in production when deploying if you deploy to the same directory. You may do so using the following:

$ composer clear-config-cache

You may also change the location of the configuration cache itself by editing the config/config.php file and changing the config_cache_path entry of the local $cacheConfig variable.

Skeleton Development

This section applies only if you cloned this repo with git clone, not when you installed mezzio with composer create-project ....

If you want to run tests against the installer, you need to clone this repo and setup all dependencies with composer.
Make sure you prevent composer running scripts with --no-scripts, otherwise it will remove the installer and all tests.

$ composer update --no-scripts
$ composer test

Please note that the installer tests remove installed config files and templates before and after running the tests.
