Usage

import promiseFlow from 'promise-flow';

promiseFlow(placeId, [getPlaceDetailResult, createAddress], {

  },
  onSuccess: (data) => {
    cache.set(data.place_id, data);
  },
});

Parameters

• startValue: The first value to be promised. If the value is not a function, it will be converted to a promised function using the promisify utility function. Note: If you pass a function as the first argument and its return value is not a promise, it will raise an error.
• callbackFns: An array of callback functions to be executed in the then method.
• option (optional): An optional object that can be used to provide onError and onSuccess callback functions.
  • onError: A function that will be triggered when the promise reaches the rejected state.
  • onSuccess: A function that will be triggered when the promise reaches the resolved state. The result of the last promise will be passed as the argument.

Return Value

A Promise object that resolves to the result of the last promise in the chain.
