What is an Application programming interface(API)?Akmal Ali
油
An application programming interface (API) is a set of subroutine definitions and communication protocols for building software. APIs make it easier for developers to use certain technologies by abstracting implementation details and only exposing necessary objects and actions. The term API was first used in 1968. APIs are used for libraries, frameworks, operating systems, remote access, web services, and design. They allow modular programming by hiding complex implementation details from users. Common examples of APIs include OpenGL, OpenMP, DirectX, and Java APIs.
This document provides an overview of web technology fundamentals, including definitions of common terms like Internet, URL, IP address and domain name. It explains how the Internet works using clients, servers, protocols like TCP/IP and standards like HTTP. It also describes markup languages like HTML and scripting languages like ASP and ASP.NET used to build dynamic websites. Finally, it provides a brief comparison of ASP.NET versus PHP and ASP.NET versus Java technologies.
This document introduces different types of web applications and frameworks. A framework provides developers with reusable code libraries and tools to build applications more efficiently. Frontend frameworks like React and jQuery reduce complexity by offering pre-written code for user interactions. Backend frameworks like Django and Ruby on Rails provide tools for server-side tasks such as authorization, routing, and database management. Frameworks give developers a foundation to build upon rather than starting from scratch.
The document discusses REST APIs and their use in enterprises. It covers API basics, the enterprise perspective, and REST basics. Key points include:
- REST APIs allow enterprises to unlock new markets, enable new business models, and transform into IoT platforms. From an architect's view, they promote modularity.
- For programmers, REST APIs provide convenience whether consuming or producing APIs. Teams are ideally formed around APIs, which serve as their deliverables.
- The document provides guidelines on REST API design, implementation, and management within an enterprise technology landscape that includes HTTP, messaging queues, service buses, and API gateways.

1. The document discusses the need for an integration specification to manage APIs that use multiple protocols and styles at large companies.
2. An integration specification would provide a single source of truth for technical metadata about APIs, including how they are structured, the data they manage, and how they relate to each other and enterprise data.
3. This would enable automated API discovery, integration, and management processes by describing APIs and their access to data products at an enterprise level.
An API is an interface that allows an application to request services from libraries or operating systems. It defines calling conventions and routines that programmers use to access these services. APIs can be language-dependent or language-independent. They specify interfaces and control object behavior but implementations provide the actual functionality. APIs allow applications to be built by combining multiple services.
The document discusses APIs design, creation and management. It covers REST principles and architecture, the rise of RESTful APIs, and designing RESTful APIs. The key points covered include:
- REST is an architectural style based on 6 principles including client-server separation, statelessness, cacheability and a uniform interface.
- Factors driving the rise of RESTful APIs include simplicity, familiarity to web developers, efficiency and scalability compared to SOAP.
- Designing RESTful APIs can follow the Richardson Maturity Model from using HTTP as a transport to introducing resources, HTTP verbs, and finally hypermedia controls.
- APIs are described using languages like Swagger/OpenAPI, RAML and API Blueprint to define
From classic web sites to web APIs to cross-device web sites.
Web APIs emerged in the 2000s as a way to make key company information accessible to developers in a controlled way via web protocols. This allowed for new applications and business models. Cloud computing further reduced costs and barriers.
Now, the next step is cross-device web sites that combine web pages and APIs to provide consistent experiences across browsers, mobile devices, and other connected systems. The "API economy" is transitional; cross-device user experiences will be more important and understood by all.
From classic web sites to web APIs to cross-device web sites.
Web APIs emerged in the 2000s as a way to make key company information accessible to developers in a controlled way via web protocols. This allowed for mobile apps and mashups of public and private web APIs.
Now, a new generation of "cross-device web sites" is emerging, powered by web APIs but focused on providing consistent user experiences across any device through pages, APIs, and connections to mobile/smart devices and partners' systems. The "API economy" is an intermediate step toward cross-device experiences, which will be more important and broadly understood.
This document provides an introduction to ASP.NET, including what it is, how it differs from ASP, and its relationship to .NET. ASP.NET is a server-side technology that uses fully-fledged programming languages supported by .NET to create dynamic web pages, as opposed to ASP which uses scripting languages. ASP.NET pages make use of WebForms, server controls, user controls and code behind files to separate the programming logic from the presentation layer. The .NET Framework provides common language runtime, base class libraries and other services to ASP.NET and other .NET languages.
This document provides an introduction to ASP.NET and the .NET framework. It discusses how ASP.NET uses programming languages like VB.NET to create dynamic web pages, compared to classic ASP which used scripting languages. The .NET framework compiles all code into Microsoft Intermediate Language (MSIL) and provides a common language runtime (CLR) and class libraries. ASP.NET exposes the .NET framework capabilities to create web forms and web services. Web forms use server controls, events, and a code-behind model to separate design from programming logic.
The document defines and explains several key technology terms related to hardware, software, browsers, HTML, HTTP, databases, SQL, APIs, programming languages, and other computing concepts. It provides brief, 1-2 sentence definitions for each term, covering topics such as computer hardware and software, web browsers, markup languages, protocols, databases, programming paradigms, and more. Examples or brief explanations are sometimes included to further illustrate the term. Overall, the document serves as a useful reference guide for fundamental technology terminology.
The document discusses microservices and API management. It defines microservices as small, independent processes communicating via APIs to compose complex applications. Benefits include improved modularity, scalability, and fault isolation. API management provides tools to publish, secure, monitor, and analyze APIs. It allows enterprises to expose APIs internally or externally in a controlled manner. The document outlines considerations around microservices and features of API management systems.
Web applications allow users to interact with dynamic content through a web browser rather than a local application. They utilize client-server architecture and communicate through HTTP requests and responses. Key components include web servers, which host the applications, and web containers that provide runtime services to web components like servlets and JSP pages. Web applications offer advantages like centralized data storage and 24/7 accessibility from anywhere but also present challenges in supporting different browsers and securing sensitive information.

How to rest api proxy to soap webserviceSon Nguyen
油
This document provides steps to create a REST API proxy for an existing SOAP web service using MuleSoft Anypoint Platform and RAML (RESTful API Modeling Language). It involves designing the REST API interface using RAML, exporting the RAML file and importing it into a Mule project. The REST flows are then configured to call the underlying SOAP service using a Web Service Consumer and Transform Message components to map requests and responses between REST and SOAP. The end result is a REST API that provides access to an existing backend SOAP service.
Frameworks are reusable software code wrapped in an API that focus on specific problem domains like compilers, decision support, media playback, web applications, and middleware. They contain utility code to help bootstrap user applications.

API stands for Application Programming Interface. It is a software interface that allows two applications to interact without any user intervention.
API provides products or services to communicate with other products and services without knowing how they are implemented.
For example News API, Crypto news API, etc that is used to fetch required data from the database.
Full stack development involves building both the front end and back end of a web application. Full stack developers work with front end technologies like HTML, CSS, JavaScript, Angular, and React as well as back end technologies like PHP, Java, Python, Node.js, and frameworks like Express, Django and Rails. They also integrate databases like Oracle, MongoDB, and SQL to store and retrieve application data. Popular full stack technologies include MEAN, MERN, and LAMP stacks.

API Gateways provide functionality like rate limiting, authentication, request routing, reporting, and more. If you've been following the rise in service-mesh technologies, you'll notice there is a lot of overlap with API Gateways when solving some of the challenges of microservices. If service mesh can solve these same problems, you may wonder whether you really need a dedicated API Gateway solution?
The reality is there is some nuance in the problems solved at the edge (API Gateway) compared to service-to-service communication (service mesh) within a cluster. But with the evolution of cluster-deployment patterns, these nuances are becoming less important. What's more important is that the API Gateway is evolving to live at a layer above service mesh and not directly overlapping with it. In other words, API Gateways are evolving to solve application-level concerns like aggregation, transformation, and deeper context and content-based routing as well as fitting into a more self-service, GitOps style workflow.
In this talk we put aside the "API Gateway" infrastructure as we know it today and go back to first principles with the "API Gateway pattern" and revisit the real problems we're trying to solve. Then we'll discuss pros and cons of alternative ways to implement the API Gateway pattern and finally look at open source projects like Envoy, Kubernetes, and GraphQL to see how the "API Gateway pattern" actually becomes the API for our applications while coexisting nicely with a service mesh (if you adopt a service mesh).

2. API
An Application Programming Interface (API)
contains software building tools, subroutine
definitions as well as communication
protocols that facilitate interaction between
systems. An API may be for a database system,
operating system, computer hardware or a
web-based system
3. Cont..
An Application Programming Interface makes
it simpler to use certain technologies to build
applications for the programmers. API can
include specifications for data structures,
variables, routines, object classes, remote calls
etc.
5. Uses of Application Programming Interfaces
Operating Systems
The interface between an operating system
and an application is specified with an API. For
example- Posix has APIs that can convert an
application written for one POSIX Operating
System to one that can be used on another
POSIX operating system.
6. Libraries and Frameworks
Often APIs are related to software libraries.
The API describes the behaviour of the system while
the libraries actually implement that behaviour.
A single API can have multiple libraries as it can have
many different implementations
A framework is based on many libraries that
implement different APIs whose behaviour is built
into the framework.
7. Web APIs
The application programming interfaces
for web servers or web browsers are
known as web APIs. These web APIs can
be server side or client side.
8. Server side web APIs have an interface that
contains endpoints which lead to request-
response message systems that are written in
JSON or XML. Most of this is achieved using a
HTTP web server. Client side web APIs are
used to extend the functionality of a web
browser. Earlier they were in the form of plug-
in browser extensions but now JavaScript
bindings are used.
9. Remote APIs
The remote application programming interfaces allow
the programmers to manipulate remote resources.
Most remote APIs are required to maintain object
abstraction in object oriented programming. This can be
done by executing a method call locally which then
invokes the corresponding method call on a remote
object and gets the result locally as a return value.
