Why Angular 2?
Angular 1 is not open for the transition from PC or Desktops to Mobile or Smartphone device. There have always been performance issues that often create hurdles in the path of developers. Application developers with Angular 1 run very slow, and not good at attracting the targeted audience. Thus, it is very important for migrating Angular 1 to Angular 2 for better features and performance.
To sum it up, Angular 2 comes with the features like:
- Improved performance.
- Better Learning Path.
- Better Mobile Support.
How to Migrate Angular 1 To Angular 2?
You can follow the Angular JS Style Guide for the migration; it involves folder to the folder structure and modularity.
You can use the Module Loader like Webpack, SystemJS, or Browserify which allow the use of Built-in module systems of ES2015 or TypeScript.
There are two ways of migrating the Angular 1 to Angular 2
ngForward can be used for creating the Angular 1 applications that look like Angular 2. The initial setup process to change the application is done by using the command mentioned below:
“npm i –save [email protected] reflect-metadata”
This command will let you install the ngForward module. You need to create the configuration file, for example, “config.js”, this file can be used to load the Angular app after it completes the bootstrap process.
ngForward is an open-source platform that allows the developers to write Angular 1 which similarly looks like Angular 2. This helps the developers to get familiar with the ng2 ( Angular 2) syntax.
Important: Keep in mind that ng-forward is created by the community, not by the Angular Code team.
At this moment, you are all set to use the fascinating features of Angular 2 in your existing Angular application.
The Angular application comprises services, controllers, and directives. Thus, when you migrate the Angular 1 to Angular 2, you need to end up having the services and components.
Angular 1 and Angular 2 services are quite similar, the controllers and directives are converted to the components. Thus, cohesion and modularity in Angular 1 code can make it quite similar.
The preparation is quite similar to the ngForward method. You will be using the component directives instead of low-level features like scope inheritance, and controller.
It is quite easy to ngUpgrade because you get the privilege of mixing and matching the Angular and AngularJS components in a similar app and be sure they seamlessly interoperate.
The upgrade is not just a single step process, and both frameworks can exist together during the transition time.
In the DOM of the ngUpgrade app are the directives and components from both the Angular and AngularJS versions. The interaction between these components takes place using their respective framework’s input and output bindings which ngUpgrade combines together.
Thus, you will be having the hybrid application which goes back and forth between two frameworks.
With Angular 2, you can make your application better and faster. Performance is the most important factor to be considered while building or running the application. With Angular 2, you can make the application performance better than before. Angular 1 was restricted to the browser-based environment while the Angular 2 version shares a plethora of rendering possibilities which includes the Native Script. Using Angular 2, developers can create native mobile applications for Android and iOS devices. You can easily build the mobile and tablet-based devices with Angular 2 and this was not possible using the Angular 1. So, enjoy the better features and services with Angular 2 and have a better experience.
The Last Words
Angular 2 is a great choice for web/native/mobile application development. It is very promising and shares the incredible features and benefits with the users. Angular 2 migration not only makes sense to the Angular 1 programmers or users but also to the companies who have been working on the JS frameworks like Snecha, Bootstrap, jquery, Backbone, and make more for building the web/mobile applications. Many of you might want to migrate Angular 1 to Angular 2 for the better experience, you can do this in two ways. Angular 2 will be your best choice for building your next mobile application, so hire an Angular Full Stack Developer and get the best of your Angular migration.
