Use below code to get yesterday date.

let yesterdayDate = new Date();
yesterdayDate.setDate(this.currentDate.getDate() - 1);
yesterdayDate = this.datePipe.transform(yesterdayDate, 'y-MM-dd');//formated date

This function adds any amount of days to the passed Date object. By passing -1 we effectiviely subtract a day.

function addDays(a_oDate: Date, days: number): Date {
        a_oDate.setDate(a_oDate.getDate() + days);
        return a_oDate;
    }
    
    console.log(addDays(new Date(), - 1));

As a sidenote, try not to use pipes in your components, and refer to How to format a JavaScript date on more details on how to format your date.
