Sample code available at: https://github.com/alvarosanchez/grails-angular-springsecurity-gr8days-warsaw Grails 3.1 enhances and improves the profile system introduced in Grails 3.0. One of the new profiles ease the creation and development of applications where the the front-end is an Angular JS application, and the backend is a Grails REST API. In this session, Álvaro (member of the Grails team at OCI, Grails committer and author of several plugins) will demonstrate how to use the Angular profile to create an application using Grails 3.1, Angular JS and Spring Security REST.

16. Creating REST
API’s with Grails

17. The REST Profile
• Targeted at building REST applications.
• REST Specific plugins and commands.
• No GSP, asset pipeline, UI plugins.
• JSON / Markup views instead.

18. The REST Profile
• Profile specific commands:
• create-domain-resource - creates an
@Resource domain
• create-restful-controller - creates a
RestfulController

19. The REST Profile
• Statically compiled, extensible JSON views:
json.person {
name "bob"
}
{"person":{"name":"bob"}}

20. Create the project
$ grails create-app -profile rest-api
-features hibernate,json-views todo
| Application created at /tmp/todo

21. REST Domain class
package com.example
import grails.rest.Resource
@Resource(uri = '/todos', formats = ['json'])
class Todo {
String description
boolean completed
}

22. RESTful Controller
package com.example
import grails.rest.RestfulController
class TodoController extends RestfulController {
static responseFormats = ['json']
TodoController() {
super(Todo)
}
def pending() {
respond Todo.findAllByCompleted(false), view: 'index'
}
}

23. URL Mappings
“/todos"(resources:"todo")
"/pending"(controller: 'todo', action: 'pending')

24. JSON View
import com.example.Todo
model {
Todo todo
}
json {
hal.links(todo)
id todo.id
description todo.description
completed todo.completed
}

25. Working with the
Angular JS profile

26. The Angular JS Profile
• Extends the REST profile.
• Adds project setup for AngularJS.
• Code generation for AngularJS.
• Scaffolding coming soon.

27. The Angular JS Profile
• Profile specific commands:
• create-ng-controller
• create-ng-service
• create-ng-domain
• create-ng-directive
• create-ng-component
• create-ng-module

28. Create the project
$ grails create-app -profile angular
-features hibernate,json-views todo
| Application created at /tmp/todo

29. Adding Security with
Spring Security REST

30. Spring Security REST
• Compatibility layer over Spring Security Core.
• Login and logout REST endpoints.
• Token validation filter.
• Stateless by default, with JWT (signed and encrypted)
• Memcached, Redis, GORM and Grails Cache token storages.
• Implicit grant support through 3rd party providers.
• RFC 6750 Bearer Token support.

31. Create the project
$ grails create-app -profile angular
-features hibernate,json-views,security todo
| Application created at /tmp/todo
