What's new in angular 6?

As several of you already recognize Angular 6 RC2 is already out and GA are going to be released any time shortly. As release date is nearing, several people are going to be curious about quite features that are being released and overall the benefits we tend to gain with this release.

At the outset, This release makes Angular lighter, quicker and more comfortable. Developers can begin loving it more because it makes their development simpler.

TYPESCRIPT 2.7+ SUPPORT:

With the support for 2.7 in place, currently, it'll be a lot of easier to code with conditional kind declarations, default declarations and strict class initialization.

ELEMENTS:

This package is primarily designed to require a plus of web elements that are being supported by all popular browsers (Except Edge). This may enable you to make an Angular portion and publish it as a web element, which may be utilized in any html page.

Transforming an element to a custom component provides a simple path to making dynamic html content in your Angular app.

ANGULAR MATERIAL WITH CDK (Component DEVELOPMENT KIT):

The initial version of Angular Material2 was released in March 2016, however, was lacking within the range of elements, stability, and compatibility with latest angular versions. Currently, it's more stable and compatible with Angular 6. Several Angular Material2 components are designed on high CDK Toolkit that is the style agnostic toolkit. With this unleash CDK Toolkit is stable and Developers will use this toolkit to create their elements with less effort as this toolkit already has most of the usually used utilities to design elements.

IVY RENDERER:

Ivy Renderer is a new rendering engine that is meant to be backwards compatible with existing render and targeted to boost the speed of rendering, and it optimizes the scale of the ultimate package. For Angular, this cannot be default renderer. However, you'll manually alter it in compiler choices.

BAZEL COMPILER:

Bazel could be a build system used for nearly all package designed at Google. With this release, we are going to begin having the Bazel compiler support. When you compile the code with Bazel Compiler, you may recompile entire code base. However, it collects only with the necessary code. It used advanced native and distributed caching, optimized dependency analysis and parallel execution.

ADDITION OF NAVIGATIONSOURCE AND RESTOREDSTATE TO NAVIGATI"qtiperar" id="tip_103" title="there is|there's">there's no way to apprehend if navigation was triggered imperatively or via the situation modification. With navigation source in place, the source of the navigation, e.g. scroll position or URL/URI modification may be known. Restored State can provide the restored navigation id that results in current navigation. These two properties facilitate us to handle multiple use cases in routing.

NgModelChange – currently this event is emitted once worth, and validity is updated on its control. Previously, it was issued before updated. because the updated price of the management is on the market, the handler can become additional powerful

Form control statusChanges – Angular vi emits an incident of "PENDING" after we call AbstractControl markAsPending.

Form pattern validators improvement – Before Angular 6, pattern validators shouldn't contain line boundaries, i.e. ^ and & and $. Previously Validator used to add these line boundaries to the validation pattern mechanically without cross-checking the existence of those line boundaries. Because of this once the developer provides line boundaries within the validator pattern Validations accustomed fail. currently, validators checks before adding line boundaries that mean Validators can work obviously with or without line boundaries

Added multiple validators for array technique of FormBuilder – Before Angular 6, there was no way to pass various validators to the form builder. array technique that is allowed currently

New optional generic type elementRef – This nonmandatory generic type will facilitate to urge hold of the native part of given custom Element as ElementRef type

FEATURES those are NEW IN ANGULAR CLI 1.7 AND SUPPORTING TO ANGULAR 6:

Schematics Support – Schematics may be a workflow technology for the fashionable web application development which may apply transforms to your project, like produce a brand new element, or change your code to repair breaking changes {in a|during a|in an exceedingly|in a very} dependency Or to feature a brand new configuration choice or new framework to an existing project. This helps to create your system to the application to assist developers in simple Use and Development and Reusability.

ng update – we've got a command currently to update the Angular dependencies of our CLI applications automatically. All your @angular/* dependencies are going to be updated to the newest stable version which incorporates all the core packages in your dependencies and devDependencies like rxjs, zone, typescript etc.., and additionally the CLI itself. This feature saves some effort in migration to the next stable version because the developer doesn't need to determine and update the versions of peer dependencies manually.

SERVICE worker SAFETY:

Service employee is a script that runs within the web browser. It additionally manages to cache for an application. However generally, e.g. {when we|once we|after we} are deploying the newest version of the app we might have to deactivate/uninstall the prevailing service employee. At this point, there are no straight thanks to disabling service employee. To full fill this need, this new release contains new script file safety-worker.js which can be a part of the production bundle that successively helps us to unregister existing service employee.

APP BUDGETS:

Many people face challenges of growing app size as we tend to add additional functionality despite setting some threshold levels at the beginning of app development. Up to now, there's no mechanism to warn us regarding growing app size. App Budgets could be a feature within the Angular CLI that permits you to line thresholds for the scale of bundles. We'll able to configure error messages/warning messages once bundle size grows on the far side the configured threshold.

Overall Angular 6 is good to release with a decent range of attention-grabbing options that make development quicker, deployment easier and bundle size lighter. However, as there's a decent range of breaking changes in Animations ngModel, Migration from Angular 5 to Angular 6 are going to be a bit tough and exciting.
