In addition to being a complete rewrite of AngularJS, Angular enables web programmers to write code in a number of programming languages – TypeScript, Dart, ECMAScript 5 and ECMAScript 6. It helps developers to build better web applications by improving dependency injection and supporting code modularity. Google has been updating Angular continuously to help users adopt the latest trend in web development.

In October 2018, Google released Angular 7.0.0 with a set of new features and enhancement. Along with being leaner and faster than Angular 6.0.0, Angular 7 focuses extensively on performance improvement and tooling changes. Many front-end developers have already upgraded from Angular 6 to Angular 7 to leverage these new and improved features. These new features will make many developers switch to Angular 7 in near future. Overview of New Features and Enhancements in Angular 7.0.0

CLI Prompts

Angular 7 comes with version 7.0.2 of the command line interface (CLI). The updated CLI prompts users to use built-in features like routing and SCSS support as they type specific commands – ng-new, ng-add and @angular/material. The users can further take advantage of the CLI prompts while working with package publishing semantics.

Updated Angular Material Specifications

While using version 7.0.0 of Angular, the developers can use updated material design specifications. In addition to coming with several visual changes, the updated Angular Material makes minor modifications to the Material Design Refresh. Google further complements the updated material design specifications with an updated Component Development Kit (CDK).

Virtual Scrolling

The updated CDK enables developers to import the scrolling module. The developers can use this module to load and unload elements from the DOM based on visible parts of the list. They can leverage the feature to improve and accelerate user experience while accessing very large scrollable lists.

Drag and Drop

The updated CDK also allows developers to import the drag-drop module. The programmers can use the module to transfer items between lists and reorder lists. The module further renders and reorders the lists automatically as a user keep moving the items.

Performance Improvement

As mentioned earlier, the most recent version of Angular emphasizes on performance improvement. It helps developers to speed up applications by warning when the initial bundle size exceeds 2MB. The developers can reduce the initial bundle size by making changes to the angular.json file after seeing the warning message. Also, Angular 7 boosts web application performance by removing reflect-metadata polyfill from polyfills.ts file automatically and converting it into a build step.

NativeScript

Often developers have to put extra time and effort to build a web application and mobile app. Angular 7 enables programmers to develop both web and mobile apps from a single project using native-script-schematics. The developers can further leverage native-script-schematics to divide the platform-specific code into multiple files. They even have the option to share the code between the web application and mobile app development projects.

Angular Console

The Angular developers can speed up command line arguments using Angular Console. They can even use the Angular Console as a robust alternative to Angular CLI. The Console further helps developers to use built-in generators for components, discover and install extensions, run custom NPM scripts, and build CLI commands visually.

StackBlitz

Angular 7 enables developers to take advantage of a widely used online IDE for web application development – StackBlitz. StackBlitz allows developers to build better applications using Visual Studio code. The developers can further start a new project using StackBlitz and export the project to Angular CLI. The features provided by the IDE further help developers to build custom web applications based on varying business needs.

Dependency Updates

Angular 7.0.0 comes with updated dependencies on third-party projects like TypeScript 3.1, RxJS 6.3 and Node 10. The developers need to use TypeScript 3.1 while working with the latest version of Angular. Likewise, they can use RxJS 6.3.3 to boost application performance and improve modularity. Also, they can use Node 10 to avail features like ESM modules, NPM v6 and performance improvement.

Angular 7.0.0 comes with several new features and enhancements while emphasizing on performance improvement. The front-end developers can switch from Angular 6 to Angular 7 to build websites and web application that deliver richer user experience. They can upgrade the existing applications from Angular 6 to Angular 7 easily and quickly by running the simple command – ng update @angular/cli @angular/core. Also, they have the option to simplify the updating process by running several special commands.
