Passing RxJs pipes as a parameter

Is there a way to pass pipes as parameters? For example:

var mypipes = [
               pipeA(() => {
                alert("a"); 
               }),
              pipeB(() => {
                alert("b"); 
               })
             ];

of(arg1, arg2, arg3).pipe(mypipes).subscribe();

Encountered an error message that says: provides no match for the signature '(source: Observable): Observable'

Answer №1

If you want to utilize only the pipe(...operators), be sure to specify the exact length of your array for pipe() to determine which overrides to use:

const operators: [OperatorFunction<number, number>, OperatorFunction<number, number>] = [
  tap(v => console.log(v)),
  tap(v => console.log(v)),
];

of(1, 2).pipe(...operators).subscribe((v) => console.log(v));

Alternatively, you can also simply use [any, any].
