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. 

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.
