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.
Informations about the package chainlink-bundle
DMS Chainlink Symfony Bundle
This Bundle wraps Chainlink library and offers a drop in solution to implement the Chain of Responsibility pattern, based on Symfony service tags. It allows you to, via configuration, setup multiple contexts and define which tags provide handlers for each.
Installation
To get the Bundle code, run:
Edit your AppKernel.php file to instantiate the Bundle:
If you are looking for other frameworks, check Packagist for wrappers and adapters.
Usage
To register new Contexts and assign handlers to them, simply add configuration entries in your config.yml.
The bundle will look for any services tagged with the tag defined above and inject them as handlers in the context you requested.
To handle a request, retrieve the Context from the Container and pass in your input.
Services that will be used as handlers need to implement the HandlerInterface from Chainlink. Its the handler's responsibility to identify which input it is responsible for, the interface contains a handles method that is called for that.
Order of Chain handling
As of version 0.3, Chainlink supports ordering of the handlers using the priority system used extensively in Symfony. The handlers will be called from high to low.
In this case OtherHandler will be called first, and then MyHandler, provided they can handle the usecase.
