The wait is finally over! Angular has released its latest version, Angular 7. Curious about its features and updates? We have got all the big details right here!<\/p>\n

Angular is undoubtedly one of the most popular JavaScript frameworks used to build web and mobile applications. It was released by Google in 2010 and received a warm acknowledgment from the development community. Till date, six stable versions of Angular framework<\/strong> are released \u2013 Angular 1 (also known as Angular JS), followed by Angular 2 and Angular 4<\/a> succeeded by Angular framework\u2019s version 5 and 6. The release of Angular framework\u2019s version 3 was skipped by Google as there were some issues with the modules.<\/p>\n

The beta version of Angular 7<\/strong> was released earlier this year, in the month of August. Its stable version is finally released. So what\u2019s new in Angular 7? Let\u2019s find out.<\/p>\n

\"\"Angular 6 was the first major release from the Angular team this year. So, before jumping to the details of Angular 7, let’s see some of the new features that were introduced in version 6.<\/p>\n

Key features introduced in Angular 6<\/h2>\n

Angular 6 supports some solid features such as Bazel Compiler support, TypeScript 2.7 support and more:<\/p>\n

Bazel Compiler<\/h3>\n

Angular 6 included the support for Bazel Compiler. It is basically a build system that is used to build nearly all software at Google. The interesting thing is that this compiler only rebuilds what is necessary (since source code changes very often, it does not make sense to rebuild the entire application for every little change; instead of rebuilding the entire application, it is wise to build only the code which actually changes). This is because it uses advanced local and distributed caching, optimized dependency and parallel execution.<\/p>\n

TypeScript 2.7 support<\/h3>\n

Angular 6 included the support for TypeScript version 2.7. With this, it was much easier for developers to code with conditional type declarations, default declarations and strict class initialization.<\/p>\n

ng update and ng add<\/h3>\n

The sixth version introduced two major new commands, update and add, in Angular CLI. With \u2018ng update\u2019 command, project dependencies are updated to their latest versions. Similar to ng update command, the \u2018ng add\u2019 command adds and configures new libraries into a project.<\/p>\n

Angular Elements<\/h3>\n

In the earlier versions of Angular framework, it was difficult to develop a widget or component that can be included in any existing web page. With Angular 6, it was made possible with the help of Angular Elements. This feature allowed developers to render their Angular elements as native web elements. This helped businesses to switch to the Angular framework for their Web Application Development<\/a><\/strong>.<\/p>\n

<ng-template><\/h3>\n

When Angular 4 was launched a year ago, the <template> element was depreciated. The launch of Angular 6 marked the elimination of the <template> element and introduction of <ng-template>. Despite the relative newness of the sixth version, Angular 7 will probably prove to be the biggest release of this year according to the developer community. As it will be backward compatible with the Angular 6, it will be easy to upgrade an Angular 6 app to Angular 7.

Ivy Renderer (Beta)<\/h3>\n

The Angular team introduced their 3rd<\/sup> rendering engine called Ivy with the launch of Angular 6. This feature augmented the speed and decreased the size of the app. Ivy is was designed to support backward compatibility with existing renderers and focused on the speed of rendering improvement. It was under development and not a part of version 6.<\/p>\n

What\u2019s new in Angular 7<\/h2>\n

In the following section, we discuss the new features and bug fixes \/ updates introduced in Angular 7:<\/p>\n

Key Features:<\/h2>\n

CLI Prompts<\/h3>\n

CLI Prompts is added to Schematics, so any package publishing Schematics can take advantage of them by adding an\u00a0x-prompt<\/code>\u00a0key to a Schematics collection.\u00a0Furthermore, the CLI will now prompt users when running common commands like\u00a0ng new<\/code>\u00a0or\u00a0ng add @angular\/material<\/code>\u00a0to help discover built-in features like routing or SCSS support.<\/p>\n

Virtual Scrolling (newly added to the CDK)<\/h3>\n

Virtual scrolling loads and unloads elements from the DOM based on the visible parts of a list, making it possible to build very fast experiences for users with very large scrollable lists.<\/p>\n

Drag and Drop\u00a0(newly added to the CDK)<\/h3>\n

Drag and drop support is now in the CDK and includes automatic rendering as the user moves items and helper methods for reordering lists (moveItemInArray) and transferring items between lists (transferArrayItem).<\/p>\n

Better Accessibility of Selects<\/h3>\n

The Angular team has worked on improving the accessibility of the Selects. They have used the native select element in the mat-form-field. With this, the performance, accessibility, and usability of the native select has become better.<\/p>\n
