There are times when I encounter a scenario where I must perform multiple operations in sequence. If each operation relies solely on data from the previous step, then it's simple with something like
pipe(startingData, TE.chain(op1), TE.chain(op2), TE.chain(op3), ...)op2 also requires data from startingData, leading to nested callbacks.
Is there a better way to structure the code without creating a pyramid of callbacks as shown below?
declare const op1: (x: {one: string}) => TE.TaskEither<Error, string>;
declare const op2: (x: {one: string, two: string}) => TE.TaskEither<Error, string>;
declare const op3: (x: {one: string, two: string, three: string}) => TE.TaskEither<Error, string>;
pipe(
TE.of<Error, string>('one'),
TE.chain((one) =>
pipe(
op1({ one }),
TE.chain((two) =>
pipe(
op2({ one, two }),
TE.chain((three) => op3({ one, two, three }))
)
)
)
)
);
