New Features in Angular 5

The Angular 5.0.0 update focuses on making the frame faster, smaller and easier to use.

Key features include:

• Emphasis is placed on facilitating the creation of progressive web applications, so that applications can be cached in the browser. The continuous concept of web applications, the product of a collective effort between Google and Mozilla, is to allow the development of browser-based applications that offer a superior experience, similar to the native one. Google is still creating support for the capability in the command line interface (CLI).

• A compilation optimizer that reduces the application by eliminating unnecessary code. (A compiler optimizer is a command-line tool).

• Make the Materials Design components compatible with the server-side representation. Google needs to fix some errors before releasing this functionality.

• Can share the code between server-side and client versions of an application using Angular Universal State Transfer API and DOM support.

• The compiler has been improved to support incremental compilation. The compiler works as a TypeScript transformation, for faster reconstructions.

• Pipes for internationalized number, date and currency. This increases stabilization in all browsers and eliminates the need for i18n polyfills.

• The size of the application is reduced due to ReflectiveInjector has been replaced with the StaticInjector for removing more polyfills.

• Multiple names are allowed for components and policies, which is useful to help users migrate without breaking the changes.

• Angular 5 has an updated Httpclient.

• CLI 1.5, which generates Angular 5 projects by default.
  For angular forms, developers can perform validations and updates of values ??in blur and send instead of each entry event.

• The RxJS reactive programming library has been updated to version 5.5.2 or later, introducing operators that eliminate the side effects of code division and tree shake problems. RxJS now scatters a version which depends on ECMAScript modules, which are extracted by default by the CLI.

• Router hooks have been added to track the router cycles from the beginning of the running protections to the end of the activation.

Angular 5 has a problem with production compilation source maps, with some maps resulting in undefined sources of errors. In addition, many previously obsolete APIs, such as Opaque Token, have been removed.
