Best Angular 6.0 Development Company in India
HTML is great for declaring static documents, but it falters when we try to use it for declaring dynamic views in web-applications. AngularJS lets you extend HTML vocabulary for your application. The resulting environment is extraordinarily expressive, readable, and quick to develop.
Angular JS 6.0
Version 6 continues and will focus on being smaller, faster and easier to use.
Angular 5 Key Features
In version 4.3 was launched HttpClientwithin @angular/common as a smaller, simpler and more powerful way to make web requests in Angular. From this new version, Google recommends using it HttpClient for all applications, and stop using the “traditional” library @angular/HTTP that is marked as obsolete.
Multiple Export Alias
Now we can provide multiple names to your components and directives in Angular 5 while exporting. Exporting a component with multiple names can help your users migrate without breaking changes.
Internationalized Number, Date, and Currency Pipes
Angular 5 has introduced new pipes for numbers, dates and currencies that increase the standardization of the process of internationalization between browsers and eliminate the need to use polyfills to achieve it.
Improved Decorator Support
Angular 5 now supports expression lowering in decorators for lambdas, and the value of useValue, useFactory, and data in object literals. Furthermore, a lambda can be used instead of a named function like so:
The build optimizer removes Angular decorators from your app’s runtime codes thereby reducing the size of your bundle and increasing the boot speed of your application. This action leads to a decreased bundle size and faster application speed.
Let’s see the important Angular 6 features.
Bootstrapping AngularJS Applications
Bootstrapping AngularJS applications automatically using the ngApp directive is very easy and suitable for most cases. In advanced cases, such as when using script loaders, you can use the imperative/manual way to bootstrap the application.
There are 3 important things that happen during the bootstrap phase:
- The injector that will be used for dependency injection is created.
- The injector will then create the root scope that will become the context for the model of our application.
- AngularJS will then “compile” the DOM starting at the ngApp root element, processing any directives and bindings found along the way.
Once an application is bootstrapped, it will then wait for incoming browser events (such as mouse clicks, key presses or incoming HTTP responses) that might change the model. Once such an event occurs, AngularJS detects if it caused any model changes and if changes are found, AngularJS will reflect them in the view by updating all of the affected bindings.
The structure of our application is currently very simple. The template contains just one directive and one static binding, and our model is empty. That will soon change!
Multiple Views, Routing and Layout Templates
Our app is slowly growing and becoming more complex. Prior to this step, the app provided our users with a single view (including the list of all phones), and all of the template code was located in the phone-list.template.html file. The next step in building the application is to add a view that will show detailed information about each of the devices in our list.
To add the detailed view, we are going to turn index.html into what we call a “layout template”. This is a template that is common for all views in our application. Other “partial templates” are then included into this layout template depending on the current “route” — the view that is currently displayed to the user.
Application routes in AngularJS are declared via the $routeProvider, which is the provider of the $route service. This service makes it easy to wire together controllers, view templates, and the current URL location in the browser. Using this feature, we can implement deep linking, which lets us utilize the browser’s history (back and forward navigation) and bookmarks.
How Animations work with ngAnimate
CSS Transition Animations: Animating ngRepeat
CSS Keyframe Animations: Animating ngView
Angular is a perfect choice for developing Single-Page Applications, creating a widget that can be added to any existing web page was not a simple task. The Angular Elements package will allow you to create an Angular component and publish it as a Web Component, which can be used in any HTML page.
Ivy is a new backward-compatible Angular renderer focused on further speed improvements, size reduction, and increased flexibility by making the size of the app smaller and the compilation faster.The Angular Team promises that switching to Ivy rendered will be smooth. This important feature will reduce the code size by gzipped the code which will make compilation faster. Ivy isn’t landing in Angular 6, though the experimental flag will be there and it’s more likely to land around v7 timeframe.
Bazel only rebuilds what is necessary, it is used almost for all software built at Google, including their 500+ apps developed in Angular. Since source code changes often, it doesn’t make sense to rebuild the entire application for every little change. Instead, we should only rebuild code that actually changed, and code that depends on the changes, With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds. So we can assume that this would be the important feature of the incremental build to most of the AngularJS Development Company
Component Dev Kit (CDK)
The Angular Material library uses component dev kit, which provides more than 30+ UI components. CDK allow us to build our own library of UI components using Angular Material. It also supports Responsive Web Design layouts eliminating the need for using libraries like Flex Layout or learning CSS Grid. CDK was released in December of 2017, but the Angular Team keeps improving it.
It is a script that runs in the web browser and manages to cache for an application. Service worker is included in angular 5. In angular 6 service worker comes with bug fixes and additional feature.
Angular CLI generates Angular artifacts using the technology called Schematics. If you decide to create your own templates and have Angular CLI explore it, Schematics will help you with this. Staring from Angular CLI 1.7, you can use the ng update that automatically updates your project dependencies and makes automated version fixes. With Schematics, you’ll be able to create your own code transformations like ng update.
The Angular team has added ng-add command in Angular-CLI which let’s user to download and install new packages in your angular app.
—–>ng add @angular/elements
If the user wants to upgrade it’s angular app from Angular 5 to Angular 6 so angular team added support for ng-update to its Angular-CLI which let the user update and upgrade packages.
—–>ng update @angular/core
The update generally follows 3 steps, and will take advantage of the new ng update tool.
- Update @angular/cli
- Update your Angular framework packages
- Update other dependencies

Added navigationSource and restoredState to NavigationStart , NavigationStart there is no way to know if navigation was triggered imperatively or via the location change. These two use cases should be handled differently for a variety of use cases (e.g., scroll position restoration). This PR adds a navigation source field and restored navigation id (passed to navigations triggered by a URL change).
The 2.6 version of Typescript’s “resolveModuleName” started to require paths passed to be separated by ‘/’ instead of being able to handle ‘\’.
Upgrading to RxJS 6
The latest version of RxJs(version 6.1.0) is added in Angular 6 with it new exciting additions and changes. These changes provide developers a boost in performance and easier to debug call stacks and improvement in modularity also making it as backward compatible as possible.
Tree Shaking in Angular 6
The Angular team moved from modules referencing services to services referencing modules to make your app smaller. This allows only bundle services into your code base in modules where they are injected.
Animations Performance Improvements
As they have updated implementation of Animations in which we no longer need the web animations polyfill and by removing polyfill from your application we can save approximately 47KB of the bundle size which improves animation performance in Safari.
These are few changes included in Angular 6
- Typescript 2.7.x supports
- Improved decorator error messages
- Fix platform-detection example for Universal
- Added to supports of Native-Element
- Added Optional generic type for ElementRef
- Updates on NgModelChange
- Add type and hooks to directive def
- Enable size tracking of a minimal CLI render3 application
- Add canonical view query
- <template> is no longer supported you have to use the previously existing <ng-template> instead.
- The Angular team has decided to extend the long-term support (LTE) to all major releases starting with v4.
- Web pack module bundler has been updated to version 4
we are looking forward to these features that will make Angular 6 even better than it’s previous versions, but what else could be improved, Angular CLI is a great tool, but it has major dependencies on the third-party software. Several times we’ have experienced broken builds in the latest releases of Angular CLI that were caused by some erroneous release of a third-party package.The Angular CLI folks are pretty good at releasing patches when errors are reported, but the process of regression testing should be improved, so these errors wouldn’t even sneak in.Look for the Breaking Changes headers in the Changelog markdown file at Github
The Angular team has started providing the regular updates from the version 2 and these are few details about the angular releases in previous years.
