Why Should You Upgrade From Angular 1 To Angular 2.0

Angular 2 is one of the most popular platforms which is a successor to Google Angular 1 framework. With its help, Angular JS developers can build complex applications in browsers and beyond. First announced in October 2014, the final version of Angular 2 was released in September 2016.

With the release of this new platform, one question pops up in mind, “Is it worth to upgrading to Angular 2 or will Angular 1 remain sufficient to progress alongside other notable frameworks and libraries like React? We will try to find an answer to this question in this blog.

1. Optimized for Mobile

Let us start with the homepage of Angular 2 it says, “One framework. Mobile and desktop.” It’s as clear of an indication as any that Angular 2 is going to serve as a mobile-first framework in order to encourage the mobile app development process.

Angular 2 has been carefully optimized for boasting improved memory efficiency, enhanced mobile performance, and fewer CPU cycles. This version also supports sophisticated touch and gesture events across modern tablet and mobile devices.

A recent benchmark study from Meteor revealed that the latest version of Angular is faster than Blaze and React. Additionally, Angular 2 will support native desktop apps for Linux, Windows, and Mac operating systems.

2. TypeScript Support

Here’s a huge perk: the latest version of Angular fully embraces Typescript. For those unfamiliar with this term, TypeScript Lang builds on top of what you already know about JavaScript but incorporates many additional tools to your ability to refactor code, write in modern JS (ECMAScript 2015), and compile to the older versions depending on browser request.

Another important facet is IDE integration is that it makes easier to scale large projects through refactoring your whole code base at the same time. Its inbuilt code completion tool effectively saves your precious time from having to look up various features from the libraries you use individually. If you are interested in Typescript, the docs is a great place to begin with.

Developers utilizing Angular 2 can enjoy the TypeScript functionality and all of its affiliated libraries, making it quite simple to integrate database interfaces like MongoDB via support of TypeScript . With libraries like React already using TypeScript, web/mobile app developers can implement the library in their Angular 2 project seamlessly.

3. Modular Development

Angular 1 created a fair share of headaches when it came to loading modules or deciding between Require.js or WebPack. Fortunately, these decisions are removed entirely from Angular 2 as the new release shies away from ineffective modules to make room for performance improvements. Angular 2 also integrates System.js , a universal dynamic modular loader, which provides an environment for loading ES6, Common, and AMD modules.

$scope Out, Components In

Angular 2 gets rid of controllers and $scope. You may wonder how you’re going to stitch your homepage together! Well, don’t worry too much − Angular 2 introduces Components as an easier way to build complex web apps and pages.

Angular 2 utilizes directives (DOMs) and components (templates). In simple terms, you can build individual component classes that act as isolated parts of your pages. Directives were a crucial part of Angular 1 and, embracing their strengths for page creation, were brought over to Angular 2. Components then are highly functional and customizable directives that can be configured to build and specify classes, selectors, and views for companion templates.

With these changes, Angular 2 will be able to provide better functionality and be easier to build your web applications from scratch. Angular 2 components make it possible to write code that won’t interfere with other pieces of code within the component itself.

4. Native Mobile Development

The best part about Angular 2 is “it’s more framework-oriented”. This means the code you write for mobile/tablet devices will need to be converted using a framework like Ionic or NativeScript.

This might seem contradictory if performance is your main concern, but Angular 2 really shines in the code structure department. One single skillset and code base can be used to scale and build large architectures of code and with the integration of a framework (like, you guessed it, NativeScript or Ionic), you get a plethora of room to be flexible with the way your native applications function.

5. Code Syntax Changes

One more notable feature of Angular 2 web development is that it adds more than a few bells and whistles to the syntax usage. This comprises (but is not limited to) improving data-binding with properties inputs,changing the way routing works, changing an appearance of directives syntax, and, finally, improving the way local variables that are being used widely.

That are small changes, but utterly crucial in this era. Once again, I would recommend looking through the Angular 2 Docs for the finer details, and an opportunity to take Angular 2 for a test drive.

Conclusion

Many Angular JS development companies and communities have shifted from discussing the first version to exclusively serving as independent Angular 2 communities. It is clearly not too late to start catching up with the latest version Angular 2. Right now, there are a plethora of great frameworks out there. ReactJS might be better at handling performance, but Angular 2 focuses on the deeper aspects of the web and mobile app development process, in particular for scaling large codebases.

In addition to this, the same team who worked on Angular 1 is also working on Angular 2, leading to some additional familiarity. Before settling for any framework, it is best to come up with a solid list of important factors and goals that are relevant to your project. When making this decision, you could do far worse than starting your newest project on Angular 2 framework.
