The CTO's Guide to Angular The CTO’s Guide to Angular Build bigger applications, smarter. CONVECTIVE Modernize Your Enterprise AngularJS usage, by some accounts, on the top 100K sites has nearly doubled in the last year… The increase in production usage is a key indicator that AngularJS is increasing its acceptance as a reliable solution for production environments. Gartner, 2015 Now more than ever mission critical applications must perform superheroic feats. Popular web and mobile platforms need to be supported from a single codebase. The user experience should surpass that of a desktop application. Development should follow a repeatable, testable pattern for efficiency and accuracy. While JavaScript has cemented itself as the language of choice for single-page web applications, the actual SDLC can be problematic. AngularJS (or simply Angular) is a revolution in web development. Through the approach of a modular framework, and by extending HTML itself, Angular solves many common challenges faced by front-end UI developers. Angular provides a consistent, well defined, structured approach to building modern applications. An MVC Framework While Angular isn’t prescriptive, developers are strongly encouraged to adopt the Model View Controller pattern when building applications. Features of an application are developed using reusable components, each dealing with a specific concern. This familiar pattern lends itself to highly maintainable applications and makes it easier to change and upgrade code when needed. Moreover, Angular implicitly handles the linkages between these components. They are bound together by Angular itself. Developers are freed from architectural issues and can focus on feature development. Backed by Google AngularJS is an open source project officially supported by Google. In addition to contributions from a vibrant open source community, a dedicated team of talented engineers at Google provide oversight, a road map, and frequent updates to the framework. The resulting credibility generated by this association has driven a groundswell of interest in Angular from developers to CTOs. CONVECTIVE 2 Focused on Productivity Out of the box, Angular provides the tools and services to begin building software today. Angular can be sprinkled into an existing application where appropriate, or form the foundation of new development efforts. Ready-made features such as services, directives, and dependency injection allow teams to hit the ground running with easily accessible concepts and constructs. Forms based applications are exceptionally well served by Angular, which provides powerful tools to accelerate development. Common tasks like form validation, styling, data binding, and state maintenance are abstracted into discrete features of the framework, allowing developers to focus what they are building instead of how to build it. A Clear Separation of Concerns An enterprise class application has many moving parts. By breaking software down into smaller units of encapsulated functionality the overall complexity of the project is reduced. Angular excels here by promoting code reuse via individual custom services, directives, and components. The result is a much cleaner, more maintainable implementation than what might have been achieved without such a framework in place. A Large Pool of Developers JavaScript is an in-demand language attracting the attention of business and government entities. This demand has fueled a surge in developers retraining for JavaScript roles. While the market is indeed tight, it remains robust with no end in sight for continued growth. The team behind Angular has produced a clear onboarding plan for new developers, in addition to numerous external online resources for picking up the framework. This means that new engineers can get productive within your projects rapidly without needing to decode a proprietary development methodology. CONVECTIVE 3 Build a Strong Safety Net Test driven development reduces the cost of change. Poorly tested applications become more expensive to develop over time. As systems become more complex, the likelihood of introducing a breaking change increases. One of Angular’s best features is the deep integration of unit testing within the framework. While many frameworks rely on external tooling to execute testing, it is available natively within Angular (integration testing with Protractor and unit testing with Karma). Go Beyond the Web The two most viable options for mobile development today are progressive web apps (PWAs) and native. Both can be targeted with Angular. Traditionally, native app development meant maintaining multiple codebases for the most popular mobile platforms: Swift for iOS and Java for Android. NativeScript is a third option for building truly native apps for Android and iOS devices using only Angular and JavaScript. With Angular, your teams can leverage existing assets to target the devices your users prefer without introducing new elements in your stack. Permissive Licensing Angular is offered freely for commercial and private usage under the popular MIT license. AngularJS is a significant advancement in how modern applications are developed. Organizations can realize strong gains in IT productivity by adopting the framework into their architectures. More information can be found at angularjs.org.

AngularJS is a JavaScript Framework AngularJS is a JavaScript framework. It is a library written in JavaScript. AngularJS is distributed as a JavaScript file, and can be added to a web page with a script tag: <script src ="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js">< / script > AngularJS Extends HTML AngularJS extends HTML with ng-directives . The ng-app directive defines an AngularJS application. The ng-model directive binds the value of HTML controls (input, select, textarea) to application data. The ng-bind directive binds application data to the HTML view. AngularJS Example <!DOCTYPE html > <html > <script src ="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js">< / script > <body > <div ng-app =""> <p>Name: <input type ="text" ng-model ="name">< /p > <p ng-bind ="name">< /p > </div > </body > </html > Example explained: AngularJS starts automatically when the web page has loaded. The ng-app directive tells AngularJS that the <div> element is the "owner" of an AngularJS application . The ng-model directive binds the value of the input field to the application variable name . The ng-bind directive binds the innerHTML of the <p> element to the application variable name .

  • Comparative Analysis of Angularjs and Reactjs
    International Journal of Latest Trends in Engineering and Technology Vol.(7)Issue(4), pp.225-227 DOI: http://dx.doi.org/10.21172/1.74.030 e-ISSN:2278-621X COMPARATIVE ANALYSIS OF ANGULARJS AND REACTJS Anurag Kumar1 and Ravi Kumar Singh2 Abstract- We live in a different era of web, we need better ways to quickly develop and deploy interactive web applications and that is where JavaScript frameworks come to the picture. JavaScript frameworks are the backbone of single page web applications development and provide superpowers to plain HTML and JavaScript. AngularJS and React.js are two most used javascript frameworks in current web development. Both frameworks are used to build interactive single page application. This research paper helps in understanding AngularJS and ReactJS. Keywords – Javascript, AngularJS, ReactJS, Two-way binding, Virtual DOM I. INTRODUCTION JavaScript is a client side scripting language which is used for providing dynamic attributes and features to the HTML webpages .JavaScript was developed for supporting the browser with feature of asynchronous communication, controlling the browser and for user interaction with the web page components. An HTML page is just a static page. JavaScript can make the website more interactive and user- friendliness, JavaScript helps easy navigation of the website and to provides interactivity. Based on JavaScript there are many frameworks are developed and also added many new features for server side scripting. JavaScript has emerged so much in web industry and if you look at the current websites there are no web technologies that are not using JavaScript. JavaScript is a dynamic scripting language, it instruct the browser to make changes to page elements after loading a page.

Kõik töö koostamisel kasutatud teiste autorite tööd, olulised seisukohad, kirjandusallikatest ja mujalt pärinevad andmed on töös viidatud. (kuupäev) (allkiri) Annotatsioon Magistritööl on kaks eesmärki: 1. Analüüsida tänapäeval populaarsemaid JavaScript raamistikke eesmärgiga arendada erinevate suurustega rakendusi. Analüüs tehakse abstraktsel näiterakendusel, mis käsitleb taaskasutatavat põhifunktsionaalsust ja raamistikuga seotud probleeme, produktiivsust, rakenduse hallatavust ja paindlikkust. 2. Võrrelda sarnase funktsionaalsusega JavaScript raamistikud eesmärgiga aru saada, millist raamistiku on parem kasutada. Lisaks ka aru saada, kas analüüsitud JavaScript raamistikuga ehitatud rakendust on võimalik toetada lähi- ja kaugtulevikus. Rakendust pannakse kokku kogukonna poolt valmis tehtud komponentidest. Autor uurib, kuidas mõjutab paigaldatud komponendid rakenduse laadimiskiirust ja töövõimet. Samuti peetakse silmas ohtusid raamistikuga arendamises: rakenduse lahtisus-kinnisus, arhitektuur ja selle paindlikkus ja haldamine, raamistiku õppimise raskus, rakenduse testimine ning kui hästi on otsingumootoritega leitav.
