- Efficiency – projects that used to take months and hundreds of lines of code now can be achieved much faster with well-structured prebuilt patterns and functions.
- Cost – most frameworks are open source and free. Since they help programmers to build custom solutions faster, the ultimate price for web app will be lower.
Smaller & Faster
In this release we deliver on our promise to make Angular applications smaller and faster. By no means are we done yet, and you’ll see us being focused on making further improvements in the coming months.
We’ve made changes under to hood to what AOT generated code looks like. These changes reduce the size of the generated code for your components by around 60% in most cases. The more complex your templates are, the higher the savings.
During our release candidate period, we heard from many developers that migrating to 4 reduced their production bundles by hundreds of kilobytes.
Read the Design Doc to learn more about what we did with the View Engine.
We have pulled animations out of @angular/core and into their own package. This means that if you don’t use animations, this extra code will not end up in your production bundles.
This change also allows you to more easily find documentation and to take better advantage of autocompletion. You can add animations yourself to your main NgModule by importing BrowserAnimationsModule from @angular/platform-browser/animations.
New Features of Angular 4
- Improved *ngIf and *ngFor
- Angular Universal
- TypeScript 2.1 and 2.2 Compatibility
- Souce Maps for Templates
After a long-awaited release of Angular back in 2016, its popularity has touched new heights, though AngularJS will hold off on giving ground in 2017.
Angular.js is often referred to as an MVW (Model-View-Whatever) framework and among the top benefits, for startups and mid-sized companies, people name: quick code production, easy testing of any app part and two-way data binding (changes in the backend are immediately reflected on the UI). Since release its ecosystem has gone beyond imagination. As for now, it is reasonably called the most used JS framework for SPAs (Single-Page Applications) development and it boasts the largest community of developers.
Angular 2 now uses one-way data binding, just like React, to improve the performance of single-page applications. But Angular has also retained two-way data binding for form elements. With the ngModel directive and banana-in-a-box syntax, your web app can simultaneously update the View and the Model, just like you did before with AngularJS.
Both Angular-s are a better option for enterprise-based applications or for strict programming environments with high standards for code readability.
It stands behind user interfaces of Facebook and Instagram, showing its efficiency within dynamic high-traffic applications.
It is rightly considered the fastest growing JS framework: as of today, there are about 1,000 contributors on Github. In MVC (Model-View-Controller) pattern React.js acts as “V” and can be smoothly integrated with any architecture. Due to the usage of virtual DOM it provides a great performance boost, comparing to Angular 1.x. In addition to that, React components can be created and re-used among applications or even transferred for public use.
Despite the fact that React has a higher learning curve, it makes app development straightforward and easy-to-understand. Furthermore it can be a perfect fit for complex, high-load and awesome software solutions.
VueJS is new, and it is gaining popularity among the web developers. VueJS was first released in 2014 as open source framework for public use under MIT license. This framework works on model-view-ViewModel (MVVM) architecture design pattern. It has data–reactive components with easy and compatible API. Vue is for developing and creating modern and sleek web interfaces.Vue is inspired by AngularJS, ReactiveJs, knockoutJS and RivetsJS.
Going deeper, Vue.js offers two-way data binding (seen in AngularJS), server-side rendering (like in Angular2 and ReactJS), Vue-cli (scaffolding tool for quick start) and optional JSX support. Its founder states that Vue 2 is one of the fastest frameworks all in all.
Vue.js is a better choice for quick development of cross-platform solutions. It can become a firm basis for high-end single page applications (SPAs) and beneficial solution to those cases, when performance is put ahead of good code organization or app structure.
Ember features two-way data binding, like Angular.js, keeping both view and model in sync for all the time. Applying Fastboot.js module it ensures prompt server-side rendering of DOM, improving performance of complex UIs.
Ember.js is a web application framework using Handlebars templates and web components to allow the development of feature-rich applications. Ember.js focuses on creating graphics and it can also be very helpful for developers who want to develop wonderful and capturing front end.
Emberjs is commonly usable for complex feature-rich web applications and website. Among the top users are Chipotle, Blue Apron, Nordstrom, Kickstarter, LinkedIn, Netflix and many others. Moreover it has an easier learning curve and there are oceans of tutorials and guide available online.
MeteorJS covers all the phases of software development cycle and takes care of such glooming processes as linking, files concatenation and others. It is of current usage in real-time application development for business companies like Mazda, IKEA, Honeywell and many others.
