How do you Get Bootstrap and Angular 2 to Work without Conflict?

Bootstrap and Angular are perhaps the most vital coding tools for any coder. While the former turns you into a brute just grabbing and injecting data greatly reducing the time it would take to churn out a website, the latter is more systematic giving you more functionality and better viewing but comes with the sacrifice of more time and coding. Nevertheless, if you thought you can get better results on your CSS or JS project with your Bootstrap developer using either of the tools, you definitely haven’t tried using both of them. 

But, it is easier said than done. While the two platforms do present you with hoards of flexibility and functionality, it is quite easy to find yourself in a fix especially if you did not hire Bootstrap developers or if this is your first time. The two platforms work differently, with different requirements and, consequently, different results and viewing. But, that does not rule out the possibility of bringing the two tools together and bringing their best attributes to project.

What are the Differences and Similarities Between Bootstrap and Angular 2?

Why Bootstrap and Angular 2 Don’t Get Along

The truth of the matter is, there is really no conflict between Bootstrap and Angular. However, there is a rule that suggests you should not use the full jQuery library on your Angular projects. The reason for this is because it makes it harder for you to realize the full potential of Angular. Additionally, if you would like to tweak the view on your project, it is best done based on the Angular data. Angular 2 comes with an add-on known as jqLite and this comes with the jQuery library. 

While the Angular and jQuery can be used differently to achieve the same goal, the same can’t be said of the Bootstrap JS, jQuery and Angular on the same pedestal. You can be able to work with Angular without jQuery. However, you do need the components of Bootstrap JS to get the front-end functioning. This is where the problem starts. 

Bootstrap JS library relies on jQuery and the way jQuery manipulates data is somewhat different from how Angular does it. Which is why, if you would like to use the two platforms together, you have to find a way to get rid of the reliance of Bootstrap on jQuery so you don’t have it impeding the functioning of Angular. That is why you get rid of it in the first place. 

jQuery is pretty basic with regards to how you build it into your DOM based on the events. It is simply a grab and injects kind of tool. So when used with a component from Bootstrap JavaScript like saying a button, what you simply have is like a toggle switch. Which when clicked goes to active if it is a button. If it is a checkbox, it is checked.

With Angular, the grabbing and injecting do not work. The data is processed and manipulated in a different way. Angular provides the Bootstrap components with variables. Then, based on the true/false nature of the component, Angular is able to bind a variable and then toggle it. Because the Bootstrap depends on jQuery to work and jQuery limits the output and benefits of Angular, you can’t have the two working on the same platform. Unless there is an alternative to locking jQuery out. 

How do you Get Bootstrap and Angular 2 to Work without Conflict? 

There are two ways that you can go around this. If you really have to use Bootstrap JS in its true form, you should load jQuery before Angular. That way, Angular will not use its built-in jQuery lite version. If it works, you save yourself lots of trouble. In case you get the “jQuery is not available” error, you have to make sure that $http.get() is working fine. 

If that doesn’t work and you’re not looking to hire Bootstrap developers, the other alternative is using UI Bootstrap. This is a lengthier and requires some coding knowledge but, it gets the job done. 

The UI Bootstrap is a project that is built by the Angular UI team that adds components that extend Angular. Unlike the Bootstrap JS, the UI Bootstrap has very different and very supportive requirements. These includes

• Needs a Bootstrap CSS file

• Needs Angular

• Does not need jQuery

Now that you know what the UI Bootstrap is, how do you integrate it into your Angular 2 project the right way?

On an Angular App

Before you can bring the UI Bootstrap, you need to have created an Angular module and controller for the app. After that, you will need to create the variables for the Collapse and for buttons. Once these are in place, you can simply pick your UI Bootstrap file and add it to the project. With that, you can be able to include the ui.bootstrap function in your Angular module. 

In one simple step, you’re able to get the directives you need that work like the components of Bootstrap JS. 

For Button Directive

To apply the UI Bootstrap for the button directive, the correct way to use the checkbox button according to the UI Bootstrap Docs is adding the ng-model to what is being defined then you can proceed to add the btn-checkbox attribute. Everything should work if you get this right. 

For the collapse Directive

Things are a bit different here. You will need to open or close the panel on the basis of the true/false value on the iscollapsed variable. To toggle the panel, you will simply use ng-click = ! iscollaped” that will toggle the variable which consequently toggles the panel. 

In case you have problems along the way, here is a video that covers the ground on matters related to the UI Bootstrap and related matters. 

The truth is, Bootstrap and Angular 2 don’t have much of a conflict. The jQuery factor is the one that triggers the hibbie jibbies on either side of the spectrum. However, with these two tips, you should be able to get over the slight hiccups and get the two platforms to work together flawlessly. 

Reasons to Go with Xamarin for Mobile Application Development

Ever since the inception and introduction of smartphones, there has always been a constant and never-ending demand for mobile application developers to always come up with something spectacular and never seen before kind of innovation with the development of mobile application. What stands even more crucial is the upgradation part which has to be followed up after some point of time of an initial application launch. 

It’s certainly not an easy task for the developers to cope up with the expectations of the users, as more than half a population of the world is using smartphone technology. A user could easily get accustomed to mobile applications, so sustaining the user therefore  with regular upgradation is pivotal. 

An upgradation can be achieved effortlessly if the developers have employed an uncomplicated programming methodology  primarily for their application development. With various operating platforms in the mix, it has only made the role of a developer even more challenging than before. One fantastic remedy which makes life easier for developers in such case is Xamarin.

What is Xamarin?

Xamarin is nothing but a cross platform app development programming, which enables one to bring in the flavor and essence of versatility across the major operating platform. In simple words, it motivates one to build an app for platforms like Android, iOS ,Windows and Blackberry by using the same code.

To know more extraction about Xamarin, Read here.

What’s so Special About Xamarin?

Xamarin has almost become very developers delight with its technical aspects starting from IDE(Integrated development environment) to a flawless user interface.

It removes the tedious and time-consuming native app development out of the equation. It comprises of logic which can be shared across all platforms. Let us see the technicalities of Xamarin in detail.

The  .Net & C# Component of Xamarin

This .Net & c# is the pillar of strength behind the success story of Xamarin. Xamarin enables one  to use C#(C-sharp) programming in the .Net framework. This C# contains coding logic which proves perfect for the various platform. 

Android runs on java. whereas, ios run on objective c. so, if one opts for native platform application development, a developer has to write and test the code for each platform separately. This is where Xamarin comes to the rescue by allowing a developer to develop an application for both the platforms by using a single code sequence powered by C#. At the same time, it retains the exclusiveness of both the platform as well.

Various Testing Methodologies

Xamarin encourages one to undergo testing of the written and developed code on  numerous devices, by which one can sort out and detect any technical abnormalities that may arise within the written code in hand before moving on to the execution part. Again, Xamarin alone provides such wide range of testing options which has been made  possible only by C#.

Best Integrated Development Environment

It’s a set of integrated tools which propels the developer to write and test software. In fact, this Kind of IDE powered feature is what that allows testing to be done across various devices as said earlier.

Flawless User Interface

In Xamarin, it’s not that everything comes so plain enough for the taking, some work goes in with writing unique codes for each platform in the development of User interface. Detailed and cautious coding is followed in developing the coding part of user interface purpose.

Eventually, Xamarin ticks all the boxes of the developer’s expectations. With almost all the aspects covered , with it’s tried and tested attributes it has all the prospects to revolutionize the mobile application development like never before.  

AngularJS is No More – Pros and Cons of TypeScript and Angular 2?

This article has been taken from Agriya blog and Agriya own this blogger.

AngularJS Basics: For Those Who Prefers jQuery

When AngularJS first appeared, it came along as a crap. It looked like many broken pieces which have to be joined together. As this framework for building web applications progressed, it has gathered a lot of followers around the world. An excellent documentation with cool examples was added to make the framework look simple and user-friendly. It performed great in learning trial apps like TodoMVC Project.

However, in case the user has only interacted with jQuery libraries before, it might be difficult for him to master AngularJS fast. It would be unfair to ignore the advantages of using AngularJS:

        MVC Done Right

        Declarative User Interface

        POJO Data Models

        Directives as the Way to Add Functionality

        Flexible when using Filters

        No need to Write Huge Codes

        In-place DOM Manipulations

        Relevant Service Providers

        Context Aware Communication

        Prepared Unit Testing

Why AngularJS Will Fail

Despite all of the benefits mentioned above, Angular was never good enough for all sorts of programs and applications. For instance, it would make no reason to ask AngularJS developers to come up with the game or a computationally intensive math program. This framework would not fit your specific problem domain. At the same time, it was very effective for generic web applications, so AngularJS served as a viable framework to build upon for a while.

The basic cause of failure is not the lack of gaming abilities, of course. It is rather the difficulty in usage. First, jQuery was brought into the place with own JS libraries that assisted in coping with mundane commands of JS:

        Class look-ups

        Selective Elements

        Animation

        AJAX

jQuery appeared and helped developers with the repetitive operations. That was the first sign that Angular JS will be replaced.

Angular 2 as a Savior

It all lasted until the day Angular 2 was announced to be released. Due to the fact Angular 2 was not expected to be compatible with its first version, a lot of changes arrived. The main question was like if it would be better to go on developing using AngularJS or quickly switch to Angular 2. Sure thing: we don’t have to catch up with the latest versions as soon as they are released, 

but in this case, it really makes sense to think about Angular 2 because of the potential Angular JS failure. If the app is small, it might be not that difficult to conduct any changes. But what if we’re talking about a large-scale project? What should AngularJS developers do then?

After collecting valuable feedback around the web, there are few things worth mentioning that might prove the superiority of Angular 2. This one seems more prepared for the current state of web standards as well as its future. Under the future standards, experts usually mean ES6\7, immutability, components, shadow DOM, service workers, mobile compatibility, modules, typescript, etc.

It is true so far that Angular 2 has removed a range of basic features of the previous versions. Well, perhaps the controllers, $scope, directives, and the module definition are gone. Some common things like ng-repeat also look different now.

Top Advantages of Switching to Angular 2

Anyway, these changes are positive as Angular 2 is more ready for the future web requirements. I would not recommend beginning a project on AngularJS today as it may ruin tomorrow. To make you feel more comfortable with choosing Angular 2, let me tell you that Google has already launched a project with this framework. If you are searching for stability, you may turn to react\elm.

When one asks to name the basic advantages of Angular 2, experts recall the following features:

        Support for web components

        Usage of Typescript

        Great performance

        General simplicity of the interface.

If you ask me, I would advise Angular 2 for large-scale projects. Yes, it requires more time to study it. Be ready that very little documentation would be available, but that is not something specialists who created this framework cannot solve.

JavaScript vs Typescript

Many people wonder whether Angular 2 would help for Ionic as well as whether Ionic 2 is Javascript or Typescript. These two are interrelated, but one has to mind the nuances.

While AngularJS was all about JavaScript, Angular 2 works with both JS and Typescript. So, it makes sense to compare JavaScript against Typescript as Angular 2 is based on it. Anyway, Angular 2 official website comes along with documentation and articles in Typescript. Also, it is important to state that Angular 2 can be used in Dart. Basically, Ionic 2 supports the same programming languages.

In any case, when you compare Angular JS and Angular 2, focus on the pros and cons of Typescript when thinking of the second one.

TypeScript’s Advantages

• It is an improved set of JavaScript. The main pros of TS are the opportunity to combine several excellent further JS characteristics together with the static typing and other TS-based structures, and Typescript will transpile into the target JS profile(s) your target audience expects. You concentrate on utilizing features that TS supports. This is especially useful for long-term projects.

• So-called type safety can assist in discovering mistakes that are caused due to the necessity to transpile TS. You can get rid of them at the early stages, within the authoring and compile time, and fight regression problems effectively. This is crucial for maintainability.

• Perfect support for inheritance and interfaces allows achieving higher OOP experience to JavaScript, which results into the improved code decoupling and reuse.

• The syntax is usually more convenient for C# or Java developers.

• AngularJs development company did not have the same opportunities as Angular 2 teams have today. By choosing Angular 2 with its Typescript, you will benefit from its model and tools to get the best experience.

• It is fair to admit, however, few of the Typecript’s cons.

TypeScript’s Disadvantages

• It is complicated to handle without the knowledge of statically typed or OOP languages. But there is always time to learn.

• The importance of applying TS definitions for non-TS libraries can turn a hassle.

• You cannot run Typescript directly without a compile stage.

• TS is unable to fix what was once broken in JS.

• Several tricks in JS can be quite complex to implement, but you can survive without them.

When Should You Choose Angular 2?

Well, some experts offer this table made of simple questions to make the final decision regarding Angular 2.

Is your project small? If it is and in case it is personal, use Angular 2.

If it is, but it’s work, then think about the team size. Does it involve more than 2 employees? If both your colleagues and manager support Angular 2, then you can also select it.

If at least one of the employees has problems with Angular 2, it is better to hold on.

If you’re the entire team, then decide whether you really feel comfortable with the framework.

Be ready that alpha-software like this can ruin some of your drafts, but in case you have mastered it in full, it would be really thankful.

You can always check the progress of Angular 2 over here.

To sum up everything said above, Angular 1 or AngularJS may still be used for small projects and short deadlines. Angular 2 may take more time to explore and get finally done, but the benefits are too obvious to miss the opportunity to switch to it as soon as it is totally ready.

        Angular 2 has much better performance than Angular 1.

        Angular 2 offers a stronger templating system.

        Angular 2 possesses easier APIs, lazy loading, simpler/faster debugging.

        Angular 2 is much more testable then Angular 1.

        Angular 2 provides nested components.

        Angular 2 makes it possible to execute more than 2 systems together.

Bootstrap 4 - 10 Ultimate Features and Benefits

Download - Bootstrap 4.0.0-alpha 3 here

1. Sass Instead of LESS

Until now Bootstrap has used LESS as its main CSS prepocessor, but for the new major release, the style rules will be refactored to Sass, which is much more popular among frontend developers, has a huge contributor base, generally easier to use and offers more possibilities. Thanks to the powerful Libsass Sass Complier written in C/C++ Bootstrap 4 will compile much faster than before.

2. New Grid Tier for Smaller Screens

Bootstrap has a sophisticated responsive grid system that allows developers to target devices with different viewports. Bootstrap 3 currently has 4 grid classes for columns, .col-xs-XX for mobile phones, .col-sm-XX for tablets, .col-md-XX for desktops, and .col-lg-XX for larger desktops. Bootstrap 4 will enhance the grid system with a fifth one that will facilitate developers to target smaller devices under 480px viewport width.

The new grid class has taken the name of the previous smallest one, and pushed the current names of the grid tiers upwards by one notch. In Bootstrap 4 the large desktops will use the .col-xl-XX class selector. It’s important to know that despite the new name they didn’t add a new class for extra large screens but for extra small ones.

3. Introduces Relative CSS Units

Bootstrap 4 finally drops the support for Internet Explorer 8. That’s really a smart step as it allows them to get rid of pesky polyfills, and convert to relative CSS units. Instead of pixels, the new major release will use REMs and EMs that make it possible to implement responsive typography on Bootstrap sites. This will also increase readability, and make sites more accessible for disabled users.

If you want to try out how relative units work with the new Bootstrap 4, check out this demo on Codepen.

4. Brand New Bootstrap Cards

The development team decided to unify some previous elements of Bootstrap’s user interface, so they decided to introduce a new UI component called Cards. Cards will replace the former wells, thumbnails and panels, and will provide users with a more streamlined workflow. Don’t worry, cards will keep familiar elements, such as titles, headers and footers of wells, thumbnails and panels.

As cards will be more flexible than the current UI components, they will allow a bigger space for creative implementations. There are some pioneers out there who have already conducted experiments on Codepen with Bootstrap Cards. You can check them out, or create your own cards.

5. New Reboot Module

The new Reboot module replaces the previous normalize.css reset file. It doesn’t ditch it; on the contrary, it builds more rules upon it. The goal of the move was to include all generic CSS selectors and reset styles in a single, easy-to-use SCSS file. You can take a look at the source code here if you want to better understand how the new module works.

It’s good to know that the new reset styles smartly set the box-sizing CSS property to border-box on the <html> element, which is therefore inherited by each child element on the page. The new style rule makes responsive layouts more manageable. If you want to experience the difference between the content-box and border-box layout types, take a look at this handy demo provided by CSS-Tricks.com (it wasn’t created for Bootstrap 4, it just shows how box-sizing generally works).

6. Opt-in Flexbox Support

Bootstrap 4 makes it possible to take leverage of CSS3’s Flexbox Layout, however – as Internet Explorer 9 doesn’t support the flexbox module – the default version of Bootstrap 4 rather makes use of the float and display CSS properties to implement a fluid layout.

Flexbox has an easy-to-use layout that can be excellently utilized in responsive design, as it provides a flexible container that either expands or shrinks itself to fill the available space the best way. Only use the opt-in flexbox feature if you don’t need to provide support for IE9.

7. Streamlined Variable Customization

All Sass variables used in the new Bootstrap release are included in a single file called _variables.scss, that will significantly streamline the development process. You don’t have to do anything else apart from copying the settings from this file into another one called _custom.scss to change the default values.

You can customize many things such as colours, spacing, link styles, typography, tables, grid breakpoints and containers, column number and gutter width, and many others.

8. New Utility Classes for Spacing

Bootstrap 3 already has many practical utility classes such as the ones that change floating or the clearfix, but Bootstrap 4 adds even more. The new spacing classes allow developers to quickly change paddings and margins on their sites.

The syntax for the new classes is quite straightforward, for example adding the .m-a-0 class links a style rule that sets margins to 0 on all sides of the given element (margin-all-0). While margins use the m- prefix, paddings are styled with the p- prefix. In the development docs you can take a look at all the new spacing utility classes.

9. Tooltips and Popovers Powered By Tether

In Bootstrap 4 tooltips and popovers makes use of the super cool Tether library, a positioning engine that makes it possible to keep an absolutely positioned element right next to another element on the same page. This means tooltips and popovers will be automatically placed properly on Bootstrap 4 websites.

Don’t forget that as Tether is a third party JavaScript library, you need to separately include it in the HTML before your bootstrap.js file.

10. Refactored JavaScript Plugins

The development team refactored each JavaScript plugin for the new release using EcmaScript 6. With the smart utilization of the latest specifications and the newest enhancements, they intend to improve the frontend experience.

The new Bootstrap 4 has also undergone through other JavaScript improvements, such as option type checking, generic teardown methods, and UMD support, that will all work together to make the most popular frontend framework run more smoothly than ever before.

5 Habitual Mistakes Node.js Developers Often Make

For the past few years, Node.js, accounting for its growth and popularity, has been a talking point for some time now. Well-establish companies like Walmart and PayPal have adapted it, making it one of the most recognized languages at present. However, as many other platforms, Node.js faces a lot of development problems that includes crucial mistakes committed by the developers themselves. This article details out the top 5 common mistakes that the developers are guilty of committing often.

Blocking The Event Loop

Being a single-threaded environment, Node.js makes sure that, no part of run in a parallel. To achieve the concurrency I/O bound operations are handled asynchronously. But this leads to the blocking of the event loop as thousands of clients are connected to it. There is no a clear-cut solution to this problem, other than to address each case individually. 

Initiating Multiple Callbacks

Relying on callbacks is what JavaScript has done forever. In Node.js, callbacks are the only way to make asynchronous elements of the code to communicate with each other. This will be the norm, at least till further enhancements are done. The package developers are also more inclined to design their APIs around the callbacks. With such great importance, the vital error that happens is using a callback more than once. Just being a bit more careful, developers can avoid this critical error.

Deeper Nesting Of Callbacks

Nesting callback so deep is not exactly a Node.js issue, but may cause problems, making the code spin out of control in a short span of time. It gets worse with the complexity of the task. Nesting callbacks in this way will end up with a hard-to-read, hard-to-maintain and error-filled code. One feasible solution is to declare these tasks as small functions and then later link them all up.

Assuming The Callbacks Will Run Synchronously

The USP of JavaScript and Node.Js, that lead to their success and popularity is the process of asynchronous programming with callbacks. With regards to other programming languages, it's easy to predict that two statements will execute one after another automatically unless some special instruction is provided to jump between statement. However is Node.js, that uses callbacks, a single task may not perform well until the previous task is finished. Node.js developers have to make sure, the next task that has to happen after the call, has to be invoked from within it.

Not Testing The Application Enough

Assuming that the application is “done” before running multiple tests on them is considered as a cardinal sin. With the availability of multiple testing tools at the disposal of the developers, there is really no excuse for not testing.

Final Words

By now, it's clear that these mistakes may cause devastating effects on the program. Node.js had made it extremely easy for beginners to learn and get started, but there are areas, where things can be easily messed up. Avoiding these crucial mistakes will let the developers to extract all the advantages, Node.js has to offer.
