• Routing
• Sessions
• HTTP requests
• Error handling

At times writing code from scratch for above things can be time consuming. But by using express it’s only a matter of few methods. Express also helps in organizing your code. EXPRESS.JS is a light-weight Web framework for Node.js which means we can build web applications using JavaScript. Since it is light, one can do many things faster and with less lines of code, than a traditional Web application built using multiple technologies.

• Express supports MVC Architecture with little bit of work.
• One can build RESTful APIs faster.
• We can use many templating languages like Jade or EJS which reduce the amount of HTML code we have to write for a page.
• Has support for NoSQL databases out of the box.
• It provides convenient, basic web-server creation/routing tools, which so essential to bare-bones node,js
• It uses very flexible, modular middleware pattern, where special middleware modules used to process different requests.
• It is very friendly to functional programming and usage of Node.js core concepts – Event-emitters, Async flow and Streams.
• It requires almost nothing to create and run the easy testable web server

Protractor is an Open Source, and  built by a team in Google on top of WebDriverJS with existing technologies such as Selenium, Node.js and Jasmine which makes writing tests a breeze. It’s also a replacement for the existing AngularJS E2E testing framework called “Angular Scenario Runner”.

Why Protractor?

Protractor is a wrapper around Selenium WebDriverJS and Selenium Server.It has new locator strategies and functions specifically for Angular apps. Automatic waiting, can execute the next step in you test the moment the webpage finishes pending tasks. One Can take the advantage of the Selenium grid to run multiple browser at once.We Can run test on both real and headless browsers.

– Easily install and setup

– Easily readable jasmine framework

– Support Data Driven test

– Include all advantages of Selenium WebDriver

– Auto-Synchronization

–  Support parallel testing through multiple browsers

–  Excellent speed

Some not so good points of Protractor::It is basically a UI driven testing tool, provide only front-end testing and there is no any detailed test report, other than test log, it needs more time to script and is more sensitive and Zero Tolerance.

Django is a web framework written in Python. Django follows explicit is better than implicit (a core Python principle), resulting in code that is very readable even for people that are not familiar with the framework. A project in Django is organized around apps. Each app has its own models, controllers, views and tests and feels like a small project. Django projects are basically a collection of apps, with each app being responsible for a particular subsystem.

Why Ruby on Rails is good for Web Development ::

• Both frameworks were born out of the need of developing web applications faster and organizing the code better. They follow the MVC principle, which means the modelling of the domain (model), the presentation of the application data (view) and the user’s interaction (controller) are all separated from each other. Django actually considers the framework to be the controller, so Django addresses itself as a model-template-view framework. Django’s template can be understood as the view and the view as the controller of the typical MVC scheme. Ruby on the other hand mainly lies in the area of web development and offers really great libraries in that field, from the web application itself over deployment libraries to things like foreman which helps you to start a big set of microservices simultaneously on your local device.
• —  Sites that would traditionally take 12 weeks to build can commonly be launched inside of 6 weeks with Ruby on Rails. This time savings results from a few factors: a leaner code-base (fewer lines of redundant code), a modular design (re-using existing components rather than building everything from scratch), and the availability of existing plugins (again, reducing the need to build features from scratch).
• —   After site launch, future modifications to your site (e.g., adding new features, making changes to the data model) can be made more quickly, for the same reasons noted above.
• —    Because of the speed with which Rails sites can be built and modified, one will spend less money to create and maintain the website — without compromising the quality, performance, or scalability of your site.

Mobx and Redux both are used to manage state in JavaScript applications. So, Is it a valid argument that MobX is offering some values that were not available in Redux and has overshadowed Redux, the same way that unidirectional data flow killed two-way data binding or how React with declarative programming killed the traditional MVC/MVVM design patterns. As MobX might be easier to learn as a beginner. Numerous developers may choose MobX if they are about to start a new project from scratch which is an advantage for MobX, having said that it could not be the case for a very long duration as we know how fast paced this industry is! Both integrate well with the philosophy of React  and the best part is we have  the privilege to change to another state management solution from MobX to Redux and Redux to MobX. In Mobx your state is mutable. On the other hand, in Redux you keep all your state in one global store or one global state.

MobX is infact simple to use, it has a short learning curve and has a quick start. MobX is best suitable for lightweighjt applications and can be used in bigger size projects too, when dealing with explicit constraints. MobX uses multiple stores and is less boilerplate. In case of Redux , it uses a single store over multiple stores to save state. Redux is influenced by functional programming (FP) principles and uses pure functions. In Redux, state is normalized like in a database. In contrast, MobX  is influenced by object-oriented programming, but also by reactive programming. And MobX uses multiple stores. In MobX there is way less code, and way faster development process. In contrast to Redux making one change can mean writing code in four files.

So, even there are so many advantages of MobX, it is hard to say that Mobx is a good choice over Redux. As big projects and big teams still need Redux .

Basically Vue.js  let one code in an highly reusable way,  create components that one can use as “html-like tags” in your page, binding data, functions and other very useful properties to every component. It has quickly overtaken React.js and jQuery in terms of popularity  and it doesn’t show signs of slowing down anytime soon.

Vue.js  is truly descriptive , declarative rendering, as oppose to other frameworks/libraries. Vue.js provides a lot of fantastic features to work with DOM. Vue.js does not require webpack. Vue.js also reduces a ton of line of codes.  Vue.js is really approachable and provides a little more structure on how to approach various things.  Vue.js is also suitable for light-weight projects. It provides very different functionality though, namely structure and modularization. In fact, one can use JQuery and Vue.js together. Vue.js was 3rd most starred project in 2016 on GitHub. Vue is simpler,  Vue.js is much easier to integrate into many frameworks like Laravel, Rails or even Django. Parsing, ajax, and data binding  can be done with Vue.js. Vue is focusing on building some of the best actions in web UI development like components, declarative UI, hot-reloading, time-travel debugging and etc.  Vue.js has a much less complicated learning curve in comparison with Angular 2.

About Backbone.js::-
– Backbone.js is a client-side MVC architecture. It is a design pattern where we separate the data from the way it is defined, manipulated and displayed. It allows you to structure your Javascript code in an MVC pattern.
– In the MVC platform, web application depends upon server for getting json data for the logic on how to display it. Here load on server is reduced and it helps in increasing the speed of the website.

-It’s easy to create small and slick web applications with frameworks like jQuery. When a project grows, however, the jQuery declarations and callbacks get more and more complex and are distributed all over the place. The code becomes more and more cluttered and hard to read.

-It provides an event-driven communication between views and models . One can attach event listeners to any attribute of a model, which gives you very nuanced control over what you change in the view.

-The BACKBONE.JS events build on top of regular DOM events, which makes the mechanism very versatile and extensible. With one line of code, for example, one can introduce a publish/subscribe pattern to backbone that ties all of your views together

-The models in Backbone.js   can be easily tied to a back-end. Out-of-the box the framework provides excellent support for Restful APIs in that models can map to a RESTful endpoint. If the API is designed correctly, backbone is already configured to access these directly for read, write, and delete operations.

-If a backend other than a RESTful API is used, backbone.js is still flexible enough to accommodate for that.

-Conventions are a great way to introduce a common coding style without the need of coming up with an extensive set of coding standards.  Backbone.js is particularly helpful to maintain a clean code base despite having multiple people collaborating on the code.

– Elasticsearch is primarily used when there is a lot of text. Traditional RDBMS don’t perform well for text search. Elasticsearch is highly customizable, extendable through plugins. One can build robust search without much knowledge quite fast.

– Along with Logstash, it is used to store and centralize logs from various sources. Integrating Kibana lets one connect to Elasticsearch cluster and create visualizations straight away. GrayLog is also using ElasticSearch as backend to store logs.

– The ELK stack can interactively search, discover, and analyze to gain insights that improve your products. It is used in the analysis of time-series data such as social media.

– Combining above uses, Elasticsearch enables enterprise search which includes Document Search, E-commerce product search, blog search, people search, site search in all its forms.

A huge amount of data affects the usability of the system performance and query response time. Using Elastic search query response time can significantly reduced.

React is a JavaScript UI library for dynamic websites. React allows to build complex UI using components as the basis of each building blocks. A component is the smallest possible representative of a group of DOM elements along with its corresponding actions and state.  It allows to create DOM, from JavaScript, that automatically updates to any state changes within the model. It’s an extremely useful framework when dealing with AJAX, dynamically updated DOM, and single page web applications. React.js is JavaScript library developed by Facebook for building user interfaces – it’s oftenly used as view in MVC applications and it doesn’t make assumptions on rest of stack so you can use it with different tech stacks.

Pros:

• Extremely easy to write UI tests cases. This is due to the virtual DOM system implemented entirely in JS
• Components can be reuse easily throughout your app. They can also be combined, and wireup together to create even more complex UIs
• One can use reactJS as an alternative, or along with popular JS libraries such as angular, backbone and jQuery
• React will automatically manage all UI updates when your underlying data changes.
• Ease of debugging-There’s a reactJS chrome extension that allows you to inspect the DOM to figure out which component is rendering a particular piece of UI.
• Works nicely with commonJS / AMD patterns

Cons:

• There’s a learning curve for beginners whom are new to web development.
• Integrating ReactJS into a traditional MVC framework such as rails would require some configuration
• It’s kind of verbose. Writing components isn’t as straight forward as pure HTML & JS
• It’s not a full framework. There’s no router nor model management libraries built into ReactJS — unlike angular or ember.
