This document discusses how to work with RESTful APIs from AngularJS applications using $http, ngResource, and Restangular. It provides examples of making GET and POST requests with each. It also covers additional topics like handling errors, authentication, and changing credentials frequently for added security.
In this short tutorial, we are going to see how AngularJS communicates with various back-ends using a general purpose $http service for issuing XMLHttpRequest (XHR) and JSONP calls, as well as the $resource service to easily target RESTful endpoints.
All examples code is available on GitHub: https://github.com/carlos-/ajs-connectserver
SPA(Single-page application) web-solutions are now a days the new standard of web development, becoming more and more popular and narrowing down the difference between a desktop and web application. JavaScript libraries/frameworks like Backbone, Knockout, Angular along with RESTful web APIs provide a great platform to develop SPA web-solutions.
OpenMRS software development is moving towards building web components that can work with each other, instead of being part of the Java module framework. Since the release of the webservices.rest module, we have focused on improving the REST resources so that we have a complete API that is accessible over HTTP and developers with different language skills can contribute. This tutorial will provide instructions on how to use the OpenMRS REST API to build custom user interfaces using modern/popular tools. Most efforts in the community have focused on using AngularJS, and we'll showcase some of the "best practices" in AngularJS development.
A presentation on how to implement RESTful Web Services with Spring MVC. This slide covers how to identify resources, use HTTP verbs, implement representations, use cache and so on.
Building RESTful applications using Spring MVCIndicThreads
REST is an alternate and simpler approach for implementing WebServices. It is based on the HTTP protocol and hence leverages a lot of existing infrastructures. It uses an uniform interface thus making it easy to build client applications. In this session we will look at the fundamental concepts behind REST (Resource, URI, Stateless Conversation ..) and how to apply it in the context of a real applcation. We will also discuss the pros & cons of RESTful vs Soap based webservices. We will discuss the design of RESTful application and then look at how to implement it using Spring MVC.

REST Easy - Building RESTful Services in Zend FrameworkChris Weldon
The epicenter of data sharing in "Web 2.0" are web services. Whether you like it or not, you are consuming literally hundreds of services a day, whether it be searching in Google, running Facebook on your mobile device, or searching the App Store on your tablet. Yet, despite our hunger for services, few have ever written one. In this session, you'll learn what are RESTful web services and how to get started creating them in Zend Framework.
Over the last few years, Airbnb’s frontend architecture has evolved to keep pace with the rapid advancement happening the JavaScript world. Starting as a humble Rails 2 + Prototype.js app in 2008, the frontend stack powering airbnb.com has gone through a few revisions, including a push towards single-page app architecture with Backbone.js and Handlebars.js, an adventure into isomorphic JavaScript with Rendr (our library for using Node.js to server-render Backbone SPAs), and most recently, a move toward React.js and a re-envisioning of our build pipeline to take advantage of CommonJS, ES6, and a Node.js-based transform system. Spike Brehm, software engineer on the @AirbnbNerds team, will walk through how we approached and executed on these changes. Plus, get excited to see a preview of our new approach to isomorphic JavaScript, allowing us to server-render React components from our Rails app.
Spike Brehm is a software engineer at Airbnb who specializes in building rich web experiences. As a JavaScript nerd, he has spent the last few years shipping web apps and prototyping Airbnb’s front-end stack, experimenting with “isomorphic JavaScript” — apps that have the flexibility to run on both the client and sever using the same codebase.
I needed to ramp-up my Dev team on RESTful systems. Existing content on this topic was either too terse or too verbose.
So I created this deck as a necessary and sufficient tutorial on REST. The goal was for my Devs to walk away with enough of an understanding to be (and want to be) dangerous.
So here it is...REST in 18 slides (ok, 21 slides if you include Cover, References, and Thank You). This is more text-heavy than I prefer, but I needed an excuse to try out SlideShare so I opted for a presentation format.
In this talk, we’ll discuss the benefits of the document-based data model that MongoDB offers by walking through how one can build a simple app. We'll show you how to design a full-blown RSS Aggregation service to replace the loss the world suffered when Google Reader was shutdown.
We'll dive deeper into topics, such as how to model your data and create your REST API using MongoDB, Express.js and Node.js (core components of the MEAN stack). This session will jumpstart your development knowledge of MongoDB.

Zach Shelby, Director of Technology for IoT at ARM and previously the co-founder of Sensinode gives and an in-depth tutrorial of the Constrained Application Protocol (CoAP) for the Internet of Things. Updates to this tutorial made on April 30th, 2014.
RESTful Architecture is effectively an implementation of Resource-Oriented architecture (ROA). ROA - is a good fit for Service oriented Architecture (SOA) implementation. Check out KickStartPros approach on RESTful API Design.
* REST = REpresentational State Transfer
* REST is Resource Based Representation. REST identifies things by JSON or XML & URIs.
* REST behavior/actions are identified by HTTP methods (GET, POST, PUT, DELETE).
* Using Uniform Interface Architecture with REST you can decouple Client (like Browser/Android App/iOS App) and Server.
* REST using Layered System and Cacheable Architecture gives better performance.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

2. What is REST?
“Representational State Transfer enables
intermediate processing by constraining
messages to be self-descriptive: interaction is
stateless between requests, standard
methods and media types are used to indicate
semantics and exchange information, and
responses explicitly indicate cacheability.”
Roy Fielding, 2000
Client-
Server
Stateless
Cacheable
Uniform
Interface
3. What is REST?
REST helps us to make apps with a frontend layer that works
with a separated backend layer that serves RESTful resources
Frontend Backend
4. Usually we create applications
that drive the logic, manage the
data and serve the html to the
client.
But now we can create an app
(for example with AngularJS and
HTML5) that works with RESTful
resources (JSON or XML)REST
5. AngularJS & REST
There are several ways to work with RESTful resources with
AngularJS.
The most used are:
• $http
• ngResource
• Restangular
6. $http
Main features:
• It’s a core Angular service
• is based on the deferred/promise APIs exposed by the $q service
• Useful methods $http.get(), $http.post() …
• Auto transforming requests and responses (XSFR, JSON)
• Cache support
• Interceptors for requests and responses
7. $http example
//GET request
$http({method: 'GET', url: '/user/123'}).
success(function(data, status, headers, config) {
// this callback will be called asynchronously
// when the response is available
}).
error(function(data, status, headers, config) {
// called asynchronously if an error occurs
// or server returns response with an error status.
});
//header config
$module.run(function($http) {
$http.defaults.headers.common.Authentication = 'Basic YmVlcDpib29w'
});
8. ngResource
Main features:
• Uses $resource (facotry that works with $http) to interact with
RESTful services
• You need to add the script
• <script src="//ajax.googleapis.com/ajax/libs/angularjs/X.Y.Z/angular-
resource.js">
• And load it into app
• angular.module('app', ['ngResource']);
• Its methods let to work directly with the RESTful resource
9. ngResource ($resource) example
//define the resource
var User = $resource('/user/:userId', {userId:'@id'});
//GET and SAVE requests
var user = User.get({userId:123}, function() {
user.newsletterSubscription = true;
user.$save(); //save is a POST request
});
//define the resource adding subscribe method
var User = $resource('/user/:userId', {userId:'@id'},
{subscribe: {method:'POST', params:{newsletterSubscription:true}}}
);
//GET and SAVE requests
var user = User.get({userId:123}, function() {
user.$subscribe();
});
10. Restangular
Main features:
• It’s an Angular service to simplify the consume of RESTful API
• Lodash (or Underscore) dependency
• Get it from https://github.com/mgonto/restangular
• Add to your APP:
• angular.module('your-app', ['restangular']);
• angular.module('your-app').controller('MainCtrl',
function($scope, Restangular) { ... });
• You don’t need to remember URLs
• It supports nested RestFUL resources and all HTTP methods.
11. Restangular example
//define a base path and extractor
Restangular.withConfig(function(RestangularConfigurer){
RestangularConfigurer.setBaseUrl("/api/v1/");
RestangularConfigurer.setResponseExtractor(function(response, op) {
return response.data;
});
});
//define the resource adding subscribe method
var baseUsers = Restangular.all('user');
baseUsers.getList().then(function (users) {
var firstUser = users[0];
firstUser.name = "Clark Kent";
firstUser.put();
});
{
"data": [
{
"id": 123,
"name": "Superman"
},
{
"id": 999,
"name": "Batman"
}
],
"status": {
"success": true,
"time": 201
}
}
12. Appendix A: the errors
HTTP has a lot of status code (4xx client errors, 5xx server errors)
But what if my request is correct, but the result of my request is not
correct (for example the users sends a wrong answer in a poll) ?
{
"data": [],
"status": {
"success": false,
"errorCode": 1001,
"errorString": "Wrong answer"
}
}
13. Appendix B: the authentication
HTTP supports authentication (basic, digest…).
In our AngularJS app we can add our authentication manager, using
the following process:
User signed in
Server returns
a secret key
The client uses
the key to sign
the requests
14. Appendix B: the authentication
To do that we can use CryptoJS to sign each request:
getSignedParams: function(path, request, myKey, mySecret) {
var params = {};
if(request == null) {
request = "";
}
else {
request = JSON.stringify(request);
}
params.apiKey = myKey;
params.signature = CryptoJS.HmacSHA1(path+request, mySecret).toString();
return params;
}
15. Appendix B: the authentication
There is a problem in this process:
If somebody steals my credentials, he can use them for the
whole session.
A solution is change the credentials in each request (useful
in a mobile app but complicated in a web app where the
user works on different tabs).
