# Registry

We are using the registry to decrease coupling between the components and modules. This way
you do not have to be avare which module is implementing a service, you only need to be aware
of the name it is registered.

## Example usage
```javascript
// Registering a new service
const registry = require('core/server/registry');
registry.add('FooBar', FooBar);

// Retrieving the service somewhere else
// (either in a different module)
const registry = require('core/server/registry');
const FooBar = registry.get('FooBar');
```
