Symfony and Angular application

This can be done with a REST API with HATEOAS support.

What is HATEOAS?

What basically HATEOAS does, is automatically add URIs to every resource being returned by your API.

An example for an HATEOAS-based response for a call to http://localhost:8080/api/customers would be:

[{
    "name": "Alice",
    "links": [ {
        "rel": "self",
        "href": "http://localhost:8080/api/customers/1"
    } ]
}]

This returns all customers and for every customer the self-linking URI to that customer's resource.

How to use HATEOAS in SF2?

You can integrate it in Symfony2 using a combination of FOSRestBundle, BazingaHateoasBundle and JMSSerializerBundle.

Your relations (links to resources) can be configured in XML, YAML, PHP or Annotations. An example with annotations would be:

use JMS\Serializer\Annotation as Serializer;
use Hateoas\Configuration\Annotation as Hateoas;

/**
 * @Serializer\XmlRoot("customer")
 *
 * @Hateoas\Relation("self", href = "expr('/api/customers/' ~ object.getId())")
 */
class Customer
{
    private $id;
    private $name;

    ...
}

See this presentation for more details.

I've never used this myself, but according to this Google groups post, BazingaHateoasBundle builds on JMSSerializerBundle to generate automatically links and embedded objects for the serialized objects, so you don't need to do anything else.

Conclusion: When you create a new item in a POST request, return the created item. BazingaHateoasBundle will automatically add the URI/route of that item to the response.
