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.

What’s New with React 16?

 

React 16.0 probably had the most anticipated release. Many new features have been added and improvements have been made. React as we all know is a JavaScript library which is used for the purpose of creating user interfaces. It is being maintained by Facebook and also by individual developers and companies simultaneously. It is known to be able to fetch rapidly changing data. This makes it suitable for developing UI from single page websites to complete mobile applications. The newest version, React 16, has a new core structure as its base which is new to React. This is known as the fiber. The fiber facilitates the new features like better error handling, async rendering etc.

A look at the following features will let us understand the difference between the old and new version and the improvements made.

  • An array of elements can now be returned with the help of a component’s render method. All you have to do to prevent key warning is to add a key to an element. This is same with all arrays. Previously, any kind of runtime errors would have broken React and lead to a cryptic error message which will then require you to refresh the page. However, React 16 has a much better way to handle these errors. If at all an error happens, the entire component will be uprooted. This will make sure that corrupted data is not displayed.
  • React 16 also has the provision of error boundaries. A complete unmounting of the component might affect user interface so error boundary is a good alternative. The error boundaries can detect the errors even before it gets to the display. It will display a UI that you can fall back on. This helps you to get a smooth user interface and is a much safer option.
  • It has also introduced portals. If a DOM node exists outside the hierarchy of a parent component then portals help with rendering the children component into the parent ones.
  • There is a huge size difference. This is due to the changed packaging. This does away with process.env checks which make it slow especially in Node.
  • React 16 also has introduced a completely new server renderer. It is entirely rewritten. This rewritten version is faster. Because it supports streaming, bytes can be sent in a much faster rate. It includes a completely rewritten server renderer. A bundle React is not needed for better rendering performance.
  • React 16 can also hydrate the server rendered HTML better upon the clients receival. The initial render and the result from the server need not match completely.

All the leading websites are now using React 16.0 and aTeamIndia is the most trusted developer when it comes to React. They have years of experience in React and are well versed with the newest version. They have a team that is updated with all the new updates and latest changes. They also have the experience of working with the latest technologies like React Native and Angular.

Laravel 5.8 – What’s New

 

The latest version 5.8 brings with it a lot of features and updates that add to the functionalities of Laravel. aTeamIndia is already up to date on this. Their team is known to use the most recent and updated technologies for their projects. The new version has many improvements and is better than all the previous versions. Following are the features of the new version:

  • Automatic Policy Resolution

Laravel has a great way of handling the authorisation of users. One way of doing this is through policies. Policies are basically classes that manage the logic around a particular resource. The previous versions require the policies to be registered in AuthService provider. However, with Laravel 5.8, the authorisation policy of a model or resource need not be manually registered. If the policy and the model follow standard Laravel naming rules, then Laravel will automatically discover it. The policy directory should also be in its default location for this purpose.

  • Carbon 2.0 Support

Working with date and time is not always easy, especially when you are working with different time zones. Carbon provides a PHP’s date and time class that makes working with them easier. The new Laravel version supports this carbon package.

  • HasOneThrough Eloquent Relationship

HasOneThrough is a new eloquent relationship that Laravel brings in its latest version. Even though this is found on other frameworks, Laravel makes use of it the best.

  • Token Guard Token Hashing

Authentication and security are taken even more seriously with this version of Laravel. A unique thing about Laravel is the token guard for API authentication. This system has been improved by storing the tokens as SHA-256. This is secure than plain text tokens.

  • Cache TTL

The new version has changed caching to seconds as compared to minutes in the previous versions. This is to make the setting of expiration time when storing items more precise. This also follows the catching library convention.

  • Scheduler Timezone Configuration

With this new version, timezone can also be configured. This is very purposeful for scheduled tasks. The previous system had a cumbersome arrangement where you have to set the timezone for every scheduled task. But here, all that is required is defining the method of scheduledtimezone.

  • Artisan Call Improvements

The previous version did not have the provision to allow artisan commands. But the new version lets you make this come using the artisan call method. Options can also be passed in a single string rather than an array of options.

  • Artisan Serve Improvements

Artisan serve is one way in which you can serve your application in no time. Running the command php artisan serve will execute the same. In previous versions, this process used to run as default. Hence, the same command could not be used to serve another application. The new version lets you serve many applications with the same command at the same time. This quickens the application serving process for Laravel.

Thus, the new version comes with many useful updates and features and is an improved version of the old Laravel.

React Native vs Flutter

 

React Native is an open-source framework supported by Facebook and was first released on GitHub. It led to the combining of native APIs of both iOS and Android.

Flutter is backed by Google and is used to create responsive iOS and Android native apps. It is a software development kit which is meant for mobile applications. The main intention behind creating it was to build applications that have great performance and fidelity. They also made sure that the applications were compatible enough to run on all platforms. Its features are that it has a thin level of code and most of the system is implemented in the Dart. This makes it easier for developers to replace, remove or make any other required changes.  Thus, it enables the developers to have great control over it.

React Native has been very popular lately especially in the ReactJS circle and in the web community. It has been highly used by companies because it is written on JavaScript. Many companies have also switched over it.

Flutter has been gaining traction from 2017. It is now widely recognised by developers and is ardently used by them in the mobile app development industry. It has the features and the potential to go a long way.

Flutter is also an open-source application framework but what makes it different is that it works on a programming language known by the name of Dart. Dart is a programming language that is used for general purposes and it was made by Google in 2011. It is mainly used for making apps that are mission-critical and with greater quality for all the three platforms: web, iOS and Android. The features of Dart have been primarily aimed at client-side development. C++ and Java form its base. The purpose of choosing Dart was because it was appropriate for the user interface requirements. Dart bridge makes the size of the application bigger but it works faster.

Meanwhile, React Native lets you build apps with the help of JavaScript. This is the main difference between both. It can compile the dynamic code of JavaScript for native view at runtime. The app in itself has a virtual machine which runs the rest of the code.

The platforms also differ in architecture. The frameworks are also based on the MVC framework. React Native’s application architecture is known as Flux. Facebook uses Flux to build client-side web applications. In Flux, the data has a unidirectional flow or a one-sided flow. React handles the view part and Flux handles model. Dart has an architecture library. This was again inspired by refluxJS and Flux. Its unidirectional flutter flow consists of actions, stores and store watchers.

At aTeamIndia, developers use both of these frameworks interchangeably depending upon the requirements of the project. Both of them have a different set of features to cater to different requirements. So, if you are confused in choosing React Native or Flutter, you know where to go. Just convey your requirements to aTeamIndia, sit back and enjoy the show.

What is Laracon?

 

Laracon is the international official conference on Laravel. It is a place where developers and Laravel enthusiasts come around to discuss and learn more about Laravel. It mainly deals with topics like Laravel framework, development, its uses and other software development news. It is not just limited to Laravel. It is a conference for discussing general software development. It is mostly held in the US and EU. There is Laracon EU for the conferences conducted in Europe. Typically, it is held in either of these places, but in 2017, for the first time ever, the conference was conducted online. In the year 2018, Laracon was held in Australia. The conference also has different sponsors each year. Laravel, Laravel News and UserScape are the primary organisers of Laracon each year.

Laracon is the representation of the huge Laravel community. It is also a great opportunity for budding Laravel developers. Not just developers but people enthusiastic about Laravel and software technology, in general, can immensely benefit from this international conference. Prominent leaders in this field come together and their insights leave a huge impact. Tyler Otwell’s introductory speech is often looked forward to. This is also an opportunity to meet new people from the same field as you and help each other grow as Laravel developers. It is a platform where new perspectives regarding technology and software can be exchanged. There is also a troubleshooting session where the problems often dealt with by the developers are shared. Listen to leaders specialising in different fields that are making a big impact. The dialogue happening in these conferences will also help developers become better professionals and advance their career. It also gives you a new perspective as you meet people with different levels of knowledge and expertise. It also brings in a community from different parts of the world.

Laracon also caters to those who are not able to take part in the conferences conducted in the US and Europe. For this purpose, they have come up with Laracon Online. This is the easiest and also the most affordable way to have access to the conference. They have also documented all the important talks and news from each Laracon conference. This also ensures that it is very inclusive and includes anybody who is interested from all across the globe. They have curated a complete day of talks which features some of the greatest Laravel experts. This can now be viewed right at your house. The 2019 event was from July 24th to 26th. Even though the event has ended, the video can still be accessed upon taking a ticket for a reasonable amount. The speakers at the event were Taylor Otwell, Matt Stauffer, Adam Wathan, Freek Van der Herten, Steve Schoger, Samantha Geitz, Marcel Pociot, Jason McCreary and Wes Bos. aTeamIndia is also a part of the Laravel ecosystem. They are one of the best Laravel developers. They are well versed in Laravel and have great expertise. They have also carried out many projects on Laravel successfully.

Laravel + Vue.js – The Perfect Couple

 

Vue.js is a framework that is progressive and particularly used for making user interfaces. If we observe the latest versions of Laravel, we can see that Vue also comes with it along with other tools like jQuery etc. Even in Laravel documentation, a small tutorial, as to how to use Vue components, is given. Following are the reasons why they form the best combination.

  • Everything Happens on The Frontend

Applications are mostly formed on an event-driven basis. They are made in such a way that the users have a flawless experience just like how they would have from an application set up in their computer. With this combination, all the app functioning is on the frontend and reloading is not necessary.

  • Reactive Components Make for An Excellent Event-Driven App

Vue JS also helps you make an application which is event-driven and the frontend comes completely prepared to handle the activity. The components are composable. This gives you the freedom to use it however you want. Because of how well it gets along with Laravel, requesting data from Laravel application is not hard and UI changes can be executed without having to reload the page.

Vue has great speed and performance which lets these changes happen seamlessly without utilising much of the resources of the computer.

  • Building Optimal Complex Frontend Pages

A frontend that completely runs on JavaScript is the only way to go if parts of your application require a lot of updates. With other JavaScript libraries that lack a virtual DOM, this will start affecting the performance because the volume of data that has to be tracked is increasing with every update. This will bring a noticeable lag in the performance. However, Vue components can automatically track and keep tabs on what needs to be updated and when there is a change in the data. This makes updates easy with only utilising limited resources. This also makes the entire application efficient.

Vue components also work well with Flux, Vuex etc. These state managers can track data in applications with a complex structure. This is possible due to the one-way binding model used by Vue.

  • Single Page Application

Single-page applications have been a great find. It lets your entire application load once. it exposes the application to a much wider crowd across the globe. It also gives users great web experience.

The above instances are examples of how well Vue incorporates with Laravel. Vue integrates nicely with Laravel. Vue.js is a framework that accelerates the whole process of frontend development. It also helps you achieve more but with using less code and resources. At the same time, Laravel is a powerful backend framework. This combination helps to make great and efficient web applications. Not all developers are well equipped to work with this combination. aTeamIndia is one such developing team that has experience in this area. They have great knowledge and experience in PHP, Laravel and JavaScript which makes it the ideal developer for making web applications with this powerful combo.

Is Xamarin the Best?

Recently many new approaches have been adopted to make mobile app development better. One of them is Xamarin. Xamarin is used for cross platform mobile development. Its unique feature is that it lets you share most of your code across all platforms. In spite of being a comparatively new tool, it has a large community of developers. It was built by developers of Mono which is an open source platform for development and it is based on the dot NET framework. It was first introduced in 2011 but was widely used in 2016.

Xamarin was primarily created as a commercial project. However, this witnessed a major change when it was acquired. It then became popular for being a cross platform which was used for developing apps within the ecosystem of Microsoft. This also made Xamarin more financially feasible. Microsoft came up with Xamarin SDK which is open source.

Features of Xamarin are as follows:

C# language

The language used by Xamarin is C#. This is created for making all applications compatible with all mobile platforms. It can be used for making high performance applications yet make them look native. This is possible because it has been compiled natively.

Based on the dot NET framework

C# is a popularly used language. It has a strong safety typing system which makes sure that the code does not behave unexpectedly. It is based on the dot NET framework and hence has features like asynchronous programming or async. This multipurpose code can now be used across all platforms. It also facilitates you to make a UI code which is specific to the platform. When you compare it to generic hybrid apps, they look native and have a better performance rate. It also provides users with better user experience.

Compilation

This platform also provides two products Xamarin iOS and Xamarin Android. They both have two different compiling systems. In iOS, source code will be compiled into ARM native code meanwhile in Android, the code will be compiled to intermediate language and then into the native assembly code at runtime. But all these activities will be handled automatically. It also handles issues like memory allocation, garbage collection etc.

Xamarin.Forms

Xamarin.Forms is particularly used for creating prototypes for a separate product designed which shares 100 percent of the code across two platforms. Xamarin.Mac is used to build applications in Mac OS. Platform SDKs are particularly used for providing access to platform specific SDKs.

aTeamIndia helps all leading business across the world and industries to use Xamarin for building high performance native mobile apps. You are also exposed to applications created by other developers. This is facilitated by their visual studio. Designing a uniform user interface across platforms helps you make a native user interface. This gives much better user experience and the application will behave how the users want it to. Xamarin has brought some path breaking approaches to mobile app development. aTeamIndia helps to bring this to all developers and users.
