Creating REST API’s with Grails

The REST Profile

• Targeted at building REST applications.

• REST Specific plugins and commands.

• No GSP, asset pipeline, UI plugins.

• JSON / Markup views instead.

The REST Profile

• Profile specific commands:

• create-domain-resource - creates an

@Resource domain

• create-restful-controller - creates a RestfulController

The REST Profile• Statically compiled, extensible JSON views:

json.person{name"bob"}

{"person":{"name":"bob"}}

Create the project

$ grails create-app -profile rest-api -features hibernate,json-views todo

| Application created at /tmp/todo

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

RESTful Controllerpackage com.exampleimport grails.rest.RestfulControllerclass TodoController extends RestfulController { static responseFormats = ['json'] TodoController() { super(Todo) } def pending() { respond Todo.findAllByCompleted(false), view: 'index' } }

URL Mappings

“/todos"(resources:"todo") "/pending"(controller: 'todo', action: 'pending')

JSON Viewimport com.example.Todomodel { Todo todo} json { hal.links(todo) id todo.id description todo.description completed todo.completed}

Working with the Angular JS profile

The Angular JS Profile

• Extends the REST profile.

• Adds project setup for AngularJS.

• Code generation for AngularJS.

• Scaffolding coming soon.

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

Create the project

$ grails create-app -profile angular -features hibernate,json-views todo

| Application created at /tmp/todo

Adding Security with Spring Security REST

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.

Create the project

$ grails create-app -profile angular -features hibernate,json-views,security todo
