The Angular CLI will now install Angular version 5.0.0 by default. The Typescript has been updated from version 2.3 to version 2.4. This release has updated the reactive extensions from version 5.4 to version 5.5.
Angular version 5 includes the build optimizer for production builds created with Angular CLI. This was done to make the bundles smaller. This works by making parts of the application "purer" by removing parts that are not required. The new version also removes the decorators from the application's runtime code, which allows developers to create smaller production bundles and speed up the applications.
Angular version 5 also offers the 'watch mode' that will only compile the necessary components of code. Developers can specify this by entering “ngc—watch”. In addition, a diagnostic pack has been built to monitor how much compiler time has been used in “watch mode”.
One of the main objectives of Angular version 5 is to make it easier for developers to create progressive web apps. This aim is to create flawless user experience regardless of the browser or the form factor. This objective remains work in progress in Angular version 5.
Angular version 5 includes new Http client that is smaller, faster, and easier to use. Some updates on Angular Form Validations. Validations will now run on every input blur event. Angular version 5 allows developers to validate on 'submit'; this is an update on Angular functionality.
Angular version 5 brings on changes with 'pipes' and developers can now use core pipes and create custom pipes. This new version of Angular has internationalized the date, number, and currency pipes to increase standardization and eliminate the need for poly-fills. The old 'pipes' module will be deprecated; however, developers can still use them in Angular version 5.
Version 5 adds new lifecycle events for the router. These events include 'GuardsCheckStart', 'ChildActivationStart' and 'ActivationStart', etc. The new version of Angular also features reactive extensions 5.5, so developers can import multiple operators with a single click. This makes the code appear cleaner.
Angular version 5 brings certain changes in Angular Universal, which provides server-side rendering of Angular applications. It is now easier to share application state between a server and a client. The new 'ServerTransferStateModule' optimizes the process of fetching data over http. In addition, Angular Universal is also offering more support for DOM using something called "domino" to execute server-side manipulations.
Version 5 also includes new debugging mechanisms, enables developers to preserve 'white space' in their code, use 'export-as' to add multiple names to components, and bypass 'zones' entirely to boost application performance.
Hire dedicated AngularJS developer since Angular 5 has improved drastically and can certainly help you build the finest web & mobile app interface to offer the most stunning user experience.
