For creating a new directory, we get a Path object for the provided path. Then, we check if the directory exists. If not, we call the static createDirectories() method of the Files class.

Iterate through Files in a directory


By using the static newDirectoryStream() method of the Files class, you can list the files in a directory this way:

Chip input using Reactive Form

The Chips component documentation from the angular material website, describes how to use the MatChipInput directive with a chip-list for adding or removing chips.

The requirements will be accessed in our template with this expression inside the *ngFor of <mat-chip></mat-chip> : *ngFor="let requirement of form.get('requirements').controls; let i = index;" In the ChipComponent class, the requirements array is accessed by using this expression: this.form.get('requirements') as FormArray; Thanks
