Presented by Nikola Vasilev on SkopjeTechMeetup 7.
Representational state transfer (REST) can be thought of as the language of the Internet. Now with cloud usage on the rise, REST is a logical choice for building APIs that allow end users to connect and interact with cloud services. This talk will deliver more insight into the challenges on building and maintaining good and clean RESTful APIs.

This Express Js tutorial will walk you through what express js is, what we can do with it, features of express js and companies that are hiring express js developers. Express Js is a Node Js framework which helps to write the API’s very efficiently. It’s a awesome framework of node js which is helping Backend development so much and it provides wide set of features to develop both web and mobile applications it is used to build single page, multipage and hybrid web applications.
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.
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.
REST Assured is a Java library .Which, provides a domain-specific language (DSL) for writing powerful, maintainable tests for Restful APIs.
Library behaves like a headless Client to access REST web services.

REST & RESTful Web Service
REST stands for Representational State Transfer
REST web services communicate over the HTTP specification, using HTTP vocabulary
If a service does not include all constraints it is not a RESTful web service.
A RESTful Introduction will cover the basics of what REST means and takes advantage of. We will talk about status codes, verbs and APIs in general.
The presentation was held by Daniel Toader and Andrei Pirjoleanu from eMAG.
The rising complexity and cost of managing legacy travel distribution systems are leading many travel companies today to adopt a REST (REpresentational State Transfer) architectural style because it provides standardized resources that enable precise interaction with other REST systems. The panelists will discuss the fundamental shift in application design required to begin thinking in terms of resources rather than objects and methods and how the OpenTravel 2.0 specification is being designed to provide a common XML resource model for the travel industry.
This presentation will discuss how the Representational State Transfer (REST) architectural style can be applied to the design of your web services.
You will learn how to use HTTP methods and status codes properly and we will discuss how to use Hypermedia As The Engine Of Application State (HATEOAS). The principles of REST and HATEOAS will be demonstrated through the Atom Publishing Protocol (AtomPub) using the Google Data APIs and other AtomPub implementations as examples.
This is the presentation from Null/OWASP/g4h December Bangalore MeetUp by Akash Mahajan.
technology.inmobi.com/events/null-owasp-g4h-december-meetup
Abstract:
This will cover the basics of Hyper Text Transfer Protocol. You will learn how to send HTTP requests like GET, POST by crafting them manually and using a command line tool like CURL. You will also see how session management using cookies happens using the same tools.
To practice along please install curl (http://curl.haxx.se/download.html).
Neo, wake up! SOA has you! :)
A complete accademic overview about the Web Oriented Architecture. A comparison between WOA and SOA is well described. What is ReST and why it is so important for the WOA. A proxy ReST-to-SOAP, based on Oracle Service Bus, is explained. Which products WOA lovers are searching for? This presentation has some "sponsored slides" from Oracle.
Building IVR applications with Tropo, a cloud-based telephony and messaging system, is easy. This presentation details support for Tropo in Grails using the tropo-webapi-grails plugin.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

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.

DevOps and Testing slides at DASA ConnectKari Kakkonen
My and Rik Marselis slides at 30.5.2024 DASA Connect conference. We discuss about what is testing, then what is agile testing and finally what is Testing in DevOps. Finally we had lovely workshop with the participants trying to find out different ways to think about quality and testing in different parts of the DevOps infinity loop.
2. Basic REST concepts
Defining your Resource-oriented architecture
HTTP status codes and error handling
Content-type negotiation
Using AJAX with REST
Versioning REST APIs
Caching and other performance
considerations
3. REpresentational State Transfer
Architecture style or design criteria
Not a standard
Stateless, client-server, cacheable
communications protocol
Use HTTP requests to post, read, and delete
data.
Lightweight
Nouns as URI, verbs as HTTP method
4. Resource
Anything that important enough to be referenced
in its singularity
Can be physical object or an abstract concept
Every resource has at least one name
Resources can be a container of other
resources
Containers are always resources
Composite design pattern
5. Resource representation
Any useful information about the state of a
resource
Specified through distinct URI or content
negotiation through headers
Canonical resource URI
Independent of format or locale language
Can be specified in Content-Location response
header of representation response
6. GET
http://www.example.com/v1/hr/employees/19328389
POST
http://www.example.com/v1/hr/employees
DELETE
http://www.example.com/v1/hr/employees/14283949
PUT
http://www.example.com/v1/hr/employees/13448784
7. Addressability
Resources are identified by URIs
Statelessness
No connection state maintained between REST
invocations
Connectedness
Resources should link together in their
representations
Uniform interface
HTTP GET, PUT, POST, DELETE, HEAD, OPTIONS
HTTP method header
HTTP status codes
8. The name and address of a resource
The scoping information to resources
Principle of addressability
Should be descriptive
Unique URIs are exposed for every resource
available from a RESTful system
Every URI designates exactly one resource
URIs are discoverable by your clients
9. No state stored on the server
Every HTTP request executes in complete
isolation on the server
Simpler to design and evolve
Easier to scale
Avoid using HTTP sessions and cookies
No side-effects
10. Standardized
GET
POST
PUT
DELETE
HEAD
OPTIONS
Represents invocation action
Resources expose uniform interface
11.
12.
13.
14.
15.
16. Primary means of reporting the outcome of a
REST operation
Use the entity-body to add ancillary qualifiers to
the outcome
Do not send back resource representations for
anything other than GET—negative impact on
performance optimizations
See Appendix B of RESTful Web Services
book for top 42 HTTP status codes
17. GET and HEAD requests should not cause any
disastrous changes to the server-side
No side effects!
Client should not be making requests just for the
side effects
Avoid exposing unsafe operations through
GET
18. Multiple invocations of an operation results in
the same result state as a single invocation
Idempotent methods: GET, HEAD, PUT,
DELETE , OPTIONS
Not idempotent: POST
19. When creating and updating resources…
PUT if, and only if, you can fully specify the full
content of the resource
POST if you are sending a command to create or
update one or more subordinates of the specified
resource
With POST, the server will determine resource URI
Use Location header in the POST response to
specify new resource URI(s) if applicable
20. HTTPS and SSL certificate validation
5 main HTTP methods
GET, HEAD, POST, PUT, DELETE
Customization of the data sent in the entity-
body of a PUT or POST request
Customization of HTTP headers
Access to the response status code and
headers
Communicate through HTTP proxies
21. Transfer and handle compressed data
Request: Accept-Encoding header
Response: Encoding header
Cache responses to requests
Conditional GETs
Common forms of HTTP authentication
Basic, Digest, and WSSE
Transparently follow HTTP redirects
22. Hierarchical
Encode data into path variables on the URI
http://maps.example.com/Earth/Europe/France/Paris
No hierarchy
Combine into one path variable, separated by
commas or semicolons
Use commas when order is important, semicolons
when it doesn’t
http://maps.example.com/Earth/24.9195,17.821
24. Version your services!
Incorporate the version into the URI
Set version to the first path variable
GET /v1/users/34923408
Representations should also be versioned
Include version information in the representation
25. Most resources do not change much
Saves client and server processing time and
network bandwidth
Implemented using HTTP headers
Response headers: Last-Modified and ETag
Request headers: If-Modified-Since and If-None-
Match
30. Microsoft Internet Explorer
Requires the Expires: -1 header
Prevents caching in IE
http://support.microsoft.com/kb/234067
31. Tools
.NET
▪ Windows Communication Foundation (WCF)
Java
▪ Spring MVC 3.0
▪ JAX-RS: CXF, Jersey, RESTEasy, RESTlet
Design the REST API
Don’t just let it happen!
Seek out resources in your domain
32. Answer the following questions, in order:
1. What are the URIs? What are the resources of
your application?
2. What is the representational format for the
resources?
3. What methods are supported at each URI?
4. What status codes could be returned for each
method?
33. Resources can be served in different
representations
XML, JSON, HTML, etc.
Content negotiation methods
Headers
▪ Accept or Content-Type
Query parameter
▪ GET /v1/users/10572?format=json
URI extension
▪ GET /v1/users/10572.xml
35. Using REST as a RPC-like mechanism
Overusing POST
Putting actions in the URI
Disguising a service as a resource
Maintaining sessions on the server
