FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Germania KG · RouteNameUrlCallable
Callable for generating full URLs using Slim 4's RouteContext and RouteParser. Works well as Twig function.
Installation with Composer
This package requires Slim Framework 4. For using Slim Framework 3, checkout the v1 branch.
Alternatively, add this package directly to your composer.json:
Introduction
The controller callable within a Slim route sometimes needs a full URL, be it for a redirect response or for rendering links. Consider this route which creates a new thing via POST and redirects to its GET representation. The redirect requires a full URL.

The RouteNameUrlCallable now hides the cumbersome stuff. It works basically as a shortcut:
Instantiation
Pass a Slim\Psr7\Request instance to the constructor. This is the default variant as of release 2.
As of release 2.2, it is also possible to inject a Slim\Interfaces\RouteParserInterface. This way will become the standard as of major release 3 (which at the time of writing has no time schedule).
Recommendation: As a replacement for injecting the request into the constructor, one is encouraged to use the static fromRequest method.
Usage
While Slim's RouteParser's relativeUrlFor, relativeUrlFor, and fullUrlFor methods return a string, the RouteNameUrlCallable returns a Slim\Http\Uri instance:
Invokation alternatives
The first RouteNameUrlCallable parameter may be an array or object which holds the name, args, and query stuff.
Placeholder args and query parameters may be overridden with the second resp. third parameter which will be merged:
Usage with Twig
Since RouteNameUrlCallable is callable, it can be used as Twig Function inside a template:
Inside you route controller, add the callable to Twig like this:
