Vue.js 3 vs Vue.js 2

 

Vue JS keeps evolving and Vue JS 3 is the latest. Vue JS 3 and Vue JS 2 go along a similar line. However, there are significant changes in both. While Vue JS 3 has maintained some of the functionalities of Vue JS 2, some revolutionary changes have been incorporated. aTeamIndia is a team of developers that are well versed in all the versions of Vue JS. Some of the features that are changed or updated from version 2 are as follows.

  • Service Code Architecture

The architecture has received a complete makeover. The very basis has been rewritten in order to make it neater and maintainable in its looks. It has been designed in such a way that developers can easily understand and also make their own contributions to this new version. For the purpose of making it less complex, internal functions have been disintegrated into smaller and individual packages. For instance, the observer module will come in its own package along with API and tests. However, this will not affect the API at the structural level. In this new version, the codebase is written with the help of typescript. aTeamIndia developers are well versed with typescript, type information and IDE support. This enables them to make contributions to the framework. Like mentioned above, now that the observer and the scheduler have a separate package, it is easier to work with new implementations.

  • Observation Mechanism

Another major difference is in the reactivity of both the versions. On couples with an observer implementation that is supported on proxy, the new version can perform reactivity tracking with full language cover. This helps to solve many of the reactivity tracking problems faced by Vue 2. The new version has a debuggable reactivity tracking that is more efficient. Following features have also been introduced as a part of the observation mechanism:

  • Exposed API
  • Lazy observation by default
  • Efficient debugging
  • Immutable observables

Other Runtime Improvements

Other runtime improvements include a smaller codebase. It is designed to be “tree-shaking friendly”. It has also proved to be faster with better performance all across the framework. This is expected to reduce the booting time of the application by half its original time. Fragments and portals are supported by a built-in system. There is a slot mechanism in the new version which lets the developers keep track of changes in the level of components. This will prevent re-renders from happening.

High Level API Changes

A very surprising feature about the new version is that there have not been any groundbreaking API changes, although usually there will be with every upgrade. Everything has either remained the same or has been made to adapt with version 2. The template syntax is also the same with only some minor changes to scoped slots syntax. Developers can use API with native ES2015. This encourages components natively. Typescript will also get additional support. The component format of version 2 is also supported in the new version. Functional components will be plain functions except async components.

15 Dollars Per Hour for CodeIgniter Redesigns

 

CodeIgniter is a prominently used PHP framework for making web applications and websites incorporating innovation. It is also widely used for building e-commerce stores. In spite of having a big set of libraries, it is very lightweight. It also enables comprehensive web development. aTeamIndia is one of the best developers in CodeIgniter. They provide a very seamless service at just 15 dollars per hour. This package not only includes designing but also redesigning services as well. Following are the features of CodeIgniter services provided by aTeamIndia.

  • Simplicity
    The framework of CI is applauded because of its simplicity. It is easy to understand and implement. The developers at aTeamIndia have easily developed expertise at the new libraries. This can also be incorporated into websites. There are also resources for guiding like tutorials and forums. Developers at aTeamIndia can easily change the framework in order to fit the needs of clients.
  • Security
    CI in itself has strong features for security. Two of its features, namely cookie encryption and decryption, makes it easier to further protect your website.
  • Flexibility
    Usually, e-commerce websites have complex problems and the developers have to be flexible. CI enables this by not restricting the developers to the coding rules. They can use their own way of coding in order to be flexible.
  • Installation Not Needed

Similar frameworks often require separate installations. This is not the case for CI. The files can be uploaded to the directory so that the framework can automatically start running. The configuration process is also easy.

  • Easy Error Handling

CodeIgniter brings with it many tools and hacks for handling errors. A mere one-line code can identify all the errors.

  • MVC Architecture

Like many other frameworks, CodeIgniter is also based on the Model-View-Controller model. The structure of the data is handled by model, display by the view and the requests by the controller. MVC forms the link between the front-end and back-end but also separates it. This feature and separation are what makes the code easier to work with. This also accelerates the process of development which is otherwise redundant.  Because of such comprehensive specialisation within the framework the speed of the website or web application is also impressive.

  • Active Community Support

CodeIgniter has a big community comprised of its users and developers. This community comes together to actively support fellow developers. So, whenever there is a query or a problem, it can be put up in the community and ideas can be exchanged. Thus, instead of one person, the whole community can come up with solutions. Everything is documented in this community which helps the developers in situations of doubt.

The above features make CI the ideal framework and aTeamIndia the ideal developers for businesses. Within a small period of time, CI can provide great solutions to your applications. aTeamIndia also adopts the best practices for CI in such a way that they modify the framework according to the needs and nature of the businesses. aTeamIndia also makes sure to bring all of these services at reasonable prices.

Best Features in React JS

 

aTeamIndia utilises some of the best features of React JS for their development services.

  • Declarative

React is known to produce user interfaces that are interactive for both websites as well as mobile applications. All you have to do is make simple views for each state and React can automatically upload and render as and when the data witnesses a change.

  • Virtual DOM

Every DOM will have a respective virtual DOM object. This is a defining feature of React. This feature produces a copy in the virtual platform of the original DOM. This is easier as a virtual DOM can be updated in less time as compared to original DOM.

  • Event handling

Another great feature of React is that it can produce an even system on its own which is also compatible with the W3C model of object. When there is a native event, this feature provides a cross browser interface. This means that the event names and fields will now be compatible. It also has a mechanism to reduce big loads of memory.

  • JSX
    JSX is another popular feature of React JS. It slightly resembles HTML. However, it is actually a combination of JavaScript and XML. These are the building blocks of React user interface. This feature makes it easier for developers to write React components. Web developers find this to be one of the best features of React as it reduces their workload.
  • Performance
    React has a feature called flux controls that employ a one way data binding system. This will automatically update what the users view and will also regulate the workflow of the application. The above mentioned virtual DOM function compares the new and old data and adds the update to the view as well.
  • React Native

React Native is a custom renderer which uses components that are Native rather than React for building the framework. All the developers have to do is to be well-versed in some basic concepts like JSX, React Native etc. React Native also gives access to many other features.

  • Component Based

In order to make a user interface, the web page and its contents are divided into components. Thus, making it component based. This component is a self containing module that will store all the visual aspects of the application. Rather than in templates, the components are written with the help of JavaScript. This enables you to send data across the application.

React JS keeps evolving by incorporating techniques and features that have never been experimented within the process of web application development. These best features of React make the best use of immutable resources. An application can be made with a better performance layer with the help of these features. React.js feature component also enables you to come up with new features without having to rewrite everything else. Since it is individually separated, it does not affect the rest of the application. aTeamIndia has been using React since its inception and has taken these features to the best of their needs.

Top Node.js Development Tips

 

aTeamIndia is always known to use the latest technologies. Thus, they are familiar with the newest features of Node.js and how to use them and the best practices to employ. Following are some of the tips to be kept in mind while using Node.js for development.

1: Use Async/await

Async/await was a big feature that came to Node.js. It completely overturned the way Async events were handled. Code bases are no longer mind-boggling. This new feature has helped in simplifying the whole process. At this point, to understand how to benefit the most from Node.js, more emphasis can be laid on previous Async programs.

2: Be Familiar with import and import()

ES modules are mostly used with Transpilers or @std/esm library. They have been supported ever since version 8.5 of Node.js. However, this was mostly experimental. There is still time for it to be ready for production. Developers can create a good foundation in this now and then, later on, follow up with the progress of the feature as and when they are updated.

3: Get Acquainted with HTTP/2

HTTP/2 comes without the flag now. This has two highlights, that is, server push and multiplexing for efficiently loading native modules in browsers. This is also something that will be adopted with many new libraries.

4: Use Prettier and Linter together

Prettier was very well received in 2017. It is a code formatter. Instead of the old school code style warnings, it formats the code style. However, there still will be errors which cannot be reformatted automatically. Therefore, it is advisable to use Prettier with Linter for projects.

5: Secure Your Node.js Applications

Securing applications is another important tip. There will be many security breaches and other vulnerabilities with not just Node.js applications but others as well. There are many platforms and tools that work well with Node.js specifications.

6: Embrace Microservices

Microservices come into use if you have trouble deploying projects that are big. There are two great options: Docker and Kubernetes. Docker provides containers which will have a filesystem that has runtime, system tools and libraries. Kubernetes is an open-source system which is for deployment and for managing applications that are containerised. It is also better to improve the existing code before delving into containers and orchestration. Thus, deployment is made easier. Initially deploying large applications used to be difficult. Microservices technologies are designed to handle these kinds of deployment.

7: Monitor Your Services

There are also tips for fixing issues even before they have a chance of being evident. They must be fixed before the users notice them. For this, there should be a good system of monitoring and alerting. This will help with the deployment of production. However, other specific tools must be used for handling complex microservice systems.

These are some of the tips that can be employed for getting the best out of Node.js. Adopting best practices will only enhance the quality of Node.js applications.

Angular 8 is Here. What’s New?

 

In order to understand how Angular 8 is different from its previous versions, we need to take a look at the history of modifications it has had. When we compare some of the other leading applications, Angular is one of the most popular frameworks designed for web development. Since its inception in 2009, it has been around but with improvements and increasing consumer base. The first version, released by Angular JS, had some issues even though it was effective. These issues can mainly be attributed to the big bundle size, complicated debugging and other technical issues. Since then, the Angular team has come up with improvements consistently and has since added features like really impactful libraries, tree shaking etc. Angular 8 is yet another version with improvements. As one of the best Angular developers, aTeamIndia is well updated with all of these features and apply them in their current projects. Following are some of the features of the new version.

  • Preview of Ivy

Ivy is one of the most notable changes brought in Angular. It is known for making use of incremental DOM. It has improved how angular functions internally without really altering its substance. It basically rewrites the code to achieve the following things.

  • Better build times
  • Better build sizes more compatible with tree-shaking
  • New potential features like lazy loading of components instead of modules

 

  • Differential Loading

The new concept of differential loading of the JavaScript makes Angular 8 perform better. This feature helps to bring about different bundles for the new apps created by Angular CLI.

  • Angular Router Backwards Compatibility

This is an old feature that has been added back. This helps to upgrade the application in an easier way when you have bigger projects. It will help you to upgrade your Angular 1.x apps to Angular 2+ right away.

  • Improved Web Worker Bundling

The new version has included web worker bundling. This is integral in the production of bundles as it makes parallelizability better and improves performance. Thus, one bundle is provided to every web worker.

  • Lazy Loading

Lazy loading is a way of reducing the size of big files. This concept is based on Angular Routing. It can bring down the size of files by lazily loading the files that are required. This new concept was introduced to tackle the issues faced by the previous configuration route.

  • Bazel Support

Another great feature introduced by the new version of Angular 8 is Bazel support. It lets you make your CLI application with Bazel. Bazel also forms a part of the very structure of the Angular framework. Bazel has many advantages. Two of the most important ones are as follows.

  • Lets you use the same tool to make backends as well as frontends.
  • Reduces the building time.

The first build will initially be slow but subsequent ones will be much faster. It also gives the app the opportunity to use libraries and modules.

Thus, with every new version, Angular consistently tries to improve on their performance.

The Best AMC (Annual Maintenance Contract)

 

An Annual Maintenance Contract or AMC is a contract which is entered by a service provider providing repair and maintenance for a company. The services offered can be for any property of the company, that is, from machine maintenance to website updates. It can also include other services like buildings, land, parking lots etc. Any company that cares about their day to day operations and a systematic production process should have the annual maintenance contract. Usually, most companies depend heavily on online platforms, machinery and equipment.

In an IT industry, there is a high dependence on machines and websites on a daily basis. If there is any kind of failure in the system or a website, there will be a big downtime which will cause loss. Instead of trying to find a fix when the whole system breaks down, it is better to have this contract in place with an IT service provider. These providers will be developers who can routinely maintain and repair the software you use particularly. aTeamIndia is one such service provider that has the expertise and crew to make sure your website, software and applications run smoothly.

Entering into such a contract will help one to grow their business. Rather than making instalments of huge sums of money every time there is a technical glitch, it is better to pay as per a contract. This will save a lot of money over the course of time in which the contract is existing. Most of these companies also offer their service at a much discounted rate if there is a contract. A contract also lets you know how much money it will cost you beforehand. This will help you to maintain budget and plan accordingly.

This contract can also help you make your hardware last longer. In software companies, you invest in a lot of technology and development. Therefore, it is always important to use the developer’s service as long as possible to make necessary changes, maintenance and updates over time. Routine maintenance will also reduce the possibility of an unexpected breakdown or downtime in your system. These service providers also provide you consistent service. Therefore, the company does not have to worry about updates and maintenance in their busy schedule. A contract of maintenance is also very beneficial when it comes to emergency requirements. Clients who have these agreements laid out will have priority in these situations. This makes sure that your problems get addressed timely.

The most important benefit is that the agreement is a way to get expert assistance when it comes to your problems. These will be people who have years of expertise in the respective field. They will be familiar with the programs you use and how your business functions. Thus, they will know how to come to the right solution.

With aTeamIndia, you will be assured the best services. Their developers are well experienced and equipped to deal with any kind of technical glitches. They undertake routine repairs and management of your software. Thus, such an AMC agreement will increase the efficiency of the business in the long run.

Spatial Data and Cesium

 

Spatial data coming to a web browser has never been easier. There are combinations of using applications for visualising spatial data. There are programming languages, frameworks and tools for executing spatial data visualisation. Out of these, the most popular tool that is used is JavaScript for both front-end and back-end development. AteamIndia employs Vue JS and Cesium combination for visualising spatial data. Vue JS as a framework is highly compatible with Cesium as they both share a common base.  There are also libraries like OpenLayers, Three.js and Babylon.js which are known for creating interactive maps as well as spatial data on maps. However, these are only fit for 2D data. Later on, 3D models supporting 3D data and maps became popular. In order to share these across programs and web, data standards were created. An example of this is CityGML. This is used particularly for sharing city models.

Cesium JS is now a very popular and widely adopted JavaScript library. It is the product of an open-source community. What makes it great is that it has enabled visualisation of 3D data possible on practically every device. However, it is not easily streamable. To make it easy, 3D tiles was developed. The geospatial data is huge and the tiles are an open specification that can stream all the 3D content like buildings, trees etc.

Even though a lot of organisations use CesiumJS and 3D tiles for the purpose of visualising 2D spatial data, in 2018, an additional mapping platform was introduced to complement this. This was the Cesium Ion platform. This is a platform that provides three options:

  • 3D tiling pipeline for streaming the data into any device effectively
  • Cesium Ion SDK for extending visualisations
  • 3D content-like imagery

In order to further modify the existing 3D tiling pipeline system, Cesium Ion introduced integration with FME data integration platform by Safe Software. This further made streaming easy and seamless. It’s a three-step process. The 3D data is first processed with FME. The uploading, tiling and streaming are dealt by Cesium.js. FME integration has many benefits. it helps to keep the web application up to date. This is because as and when there is a change in the underlying data, new visualisations will be created automatically. Thus, there is an automated system of workflow.

Those who use FME will have two format writers. One for writing the 3D tiles and the other for 3D point clouds. These make visualising with Cesium extremely easy. Safe Software also comes up with updated features of FME integration. The next one is this year, 2019, which will be a new Cesium Ion transformer. This new feature will extract the data from FME and process it into Cesium Ion creating a web visualisation with URL. This will be displayed right away in the browser. Cesium by itself and with the collaborations with other tools and frameworks have proved to be a great application for mapping spatial data. It is now widely used in all industries like sports, automobiles etc.

Why Everyone Use Node JS for Back-End

 

Node JS is very popular among developers. However, it is not often realised as to how beneficial it is for the back-end. It is a runtime application environment which is designed for writing a server-side application in JavaScript. These days, the servers require highly scalable and real-time situations which Node.js can meet because of its one of a kind I/O model.

Being lightweight is one of Node’s primary feature. Its efficiency along with its capability to use JavaScript for both back-end and front-end development are its other major features. These are also some of the reasons why many big corporations have used Node JS for their development functions.

One of the greatest perks of Node JS comes from the fact that you can use the same language for both front-end and back-end. This will be a huge relief to the development team. It will help them focus on other important functions. This also makes the team cross-functional thereby reducing the development cost margin. It will also be a familiar domain for all engineers and developers as the code base is JavaScript, which everyone is familiar with. Another way in which Node accelerates the whole development procedure is by enabling you to reuse and also share the code for both back-end and front-end development. The community of Node JS users is also increasing consistently. So, there is a lot of information available readily. It is also open-source and free. Node has something called npm which is a packaging manager. The registry of npm has great open source tools. These options make Node a great choice for development.

Node JS also caters to certain unique yet important specifications that some applications require. Like, for example, it is appropriate for applications that have the need to process a big volume of short messages with low latency. These are called real-time applications and can benefit the most from Node JS. It caters real-time collaborative editing which lets you see the document being edited as someone else sees it. There might be many other applications which have a similar construct and functions. However, there are certain specifications that only Node JS can meet. For instance, if there are many requests, then Node JS can cope up with this in terms of speed and efficiency. It is also useful for situations requiring speed and more scalability.

Node JS should also be adopted as it meets the two most important requirements of modern-day web applications. These are low response times for processing many requests and sharing things like code between client and server. They also carry out many activities on client-side. For all these reasons, Node JS is popularly used for single-page applications. Because of these specifications of Node JS, aTeamIndia is also its avid user. It uses it for development of both back-end as well as front-end. Node JS has helped them create high-performance applications for their clients in less time. Using technologies like Node.js is what made aTeamIndia a great development company.

PWA and Vue.js

 

A web application that lets you browse even when you have bad network connectivity is what PWA represents. It is also an application that lets the users engaged even while it is offline. PWA also makes up to date data accessible. Leading companies like Twitter, AliExpress, Forbes etc are some of the users of PWA. There are many other companies that prefer because of these and have many other great features. Progressive apps can redefine the future of web applications.

A Progressive Web Application (PWA) is a web application that particularly offers an application-like user experience but on the web. Now this seemed impossible until recently but modern technologies like service workers and native APIs have made PWAs help to improve.  Vue JS and progressive web apps work well together and many developers adopt Vue js PWA projects. aTeamIndia has great experience in both the application and the tool and can work well with these kinds of projects. aTeamIndia envisages bringing both of these together to create a high performing web application.

A service worker runs independently on the browser because it is a background worker. It does not exhaust the main thread when it is executed. This feature is what lets an application run seamlessly even when it is offline. Even though this seems easy if not done by the right set of developers, things can go bad. aTeamIndia has a community-driven tool for helping with setting up. Following are the steps to be followed for building a progressive web app with the help of Vue.js.

The first and foremost step is to install Vue-CLI if it is not installed in the system already. After this, the next step is to initialise the application.

At this point, there will be certain questions that have to be answered. Which is the type of Vue build to be used? Whether a Vue router is installed, whether an ESLint should be used and the like. It will also have to be decided whether unit tests need to be set up. Certain default answers will also be provided.

After this, there will be a process to create a project folder that has the following subdivisions, build, src, configuration, static and test. The distinguishing difference seen in this template is in the build/webpack.prod.conf.js file.

When the build command is running, the plugin will start generating or running a service worker file in the background. This service worker caches the files matching the glob expression, “staticFileGlobs”.

The next step is to import db.json that has just been created and consume it in src/App.vue. This will then display the desired result in the browser. This has to be imported to Vue object and added to the template of the app.

An app template can also be added to make the page look more presentable and attractive. The next step is to set perspective and backface-visibility to the element fixes.

Changes can also be made to change screen sizes and make grids more responsive. Thus, combining Vue JS and PWA is easy and yields the best results.

The Story of Evan You, the Father of Vue.js

 

Evan You is the man behind Vue.js which is one of the most popular frameworks existing today. Born and brought up in Wuxi, which is a small city in China, Evan did his schooling in Shanghai. So, he had to commute a considerable distance every day. Upon completing his high school in China, he went to the US for pursuing his higher studies and college. This is where his interest in computers began as computers were easily available there. Even then he did not get involved in programming that much. He was more interested in playing games. Back in high school, he loved playing Flash because of interactive storytelling experiences.

He was attracted to JavaScript because of how he can easily build things and share them with the world. It was as easy as getting the URL and sending it with a browser. This is also what attracted him to the web. At his job at Google, he got a lot of experience working with prototyping in the browser. It started with just an idea and they wanted a tangible result as soon as possible. At that time, some of the projects that they were involved with used Angular. What attracted Evan about Angular was its two unique features, data binding and dealing with DOM. But it also had many concepts which made it difficult and heavy to use. While considering this, Evan had the great idea of extracting only those concepts from Angular that he liked and making something lightweight. This is what ultimately led to Vue.JS.

Because he was fascinated by the internal implementation mechanism, he started replicating features as a way of experiment. For example, how a minimal feature set like data binding would work. Once he started working on it, the more he understood the potential it has. He then gave it a name. Once he made this in 2013, he was also inspired to share it with others so that they can also learn and benefit from it. Then in 2014, he released it as an actual project. He then put it out on GitHub and forwarded a link to Hacker News. This is where it rose to fame. It got voted to the front page.

A lot of people started using it and it became a big project in GitHub. What Evan mainly focused on was making it more accessible by reducing the price. He then tried out crowdfunding on Patreon. This idea worked because many of the Vue users were from the Laravel community. He then started off by charging it for a very reasonable and nominal amount of ten bucks per month. This again attracted a lot of traction. Thus, Vue js has now become one of the mostly used frameworks for creating user interfaces and single-page applications. It has inspired many developers all across the world. aTeamIndia has a team of passionate developers who were inspired by Evan and adopted his suggested best practices while using Vue js for their projects.
