As we know there have been several releases of Angular till today, we announce you with the latest release of Angular 7 including the package of best features.

To update angular version, following command will be used.

 Let’s have a brief introduction with the features.

CLI Prompt

The very first feature has been a blessing for the developers. With the CLI prompt the users will now be prompted the expected commands, thus saving both their time and energy. The new CLI version is good for commands like ‘ng new’ or ‘ng add. To install latest version of CLI use the below command.

npm install -g @angular/cli@latest

After updating that, try to create a new angular project by ‘ng new’ + Enter.

Better Accessibility for Selects

The job of every company is to offer ease of accessibility, whether you are an offline or online serving organization. Angular 7 nurtures the needs of every consumer by offering the improved and more accessible version of select box. We can use the native select inside mat-form-field. it has more flexibility and better performance than the mat-select.

The CDK also supports for Drag & Drop, it includes following features:

● The items are rendered on their own upon the drag and drop request of the user.

● It includes helper methods for reordering/transfering items in the lists.
