Overview

TypeScript definitions for bluebird

Index

Functions

function getNewLibraryCopy

getNewLibraryCopy: () => typeof Bluebird;
  • Returns a new independent copy of the Bluebird library.

    This method should be used before you use any of the methods which would otherwise alter the global Bluebird object - to avoid polluting global state.

function noConflict

noConflict: () => typeof Bluebird;
  • This is relevant to browser environments with no module loader.

    Release control of the Promise namespace to whatever it was before this library was loaded. Returns a reference to the library namespace so you can attach it to something else.

function setScheduler

setScheduler: (scheduler: (callback: (...args: any[]) => void) => void) => void;
  • Changes how bluebird schedules calls a-synchronously.

    Parameter scheduler

    Should be a function that asynchronously schedules the calling of the passed in function

Classes

class AggregateError

class AggregateError extends Error implements ArrayLike<Error> {}
  • A collection of errors. AggregateError is an array-like object, with numeric indices and a .length property. It supports all generic array methods such as .forEach directly.

    AggregateErrors are caught in .error handlers, even if the contained errors are not operational.

    Promise.some and Promise.any use AggregateError as rejection reason when they fail.

The promise's fulfillment value is an array with fulfillment values at respective positions to the original array. If any promise in the array rejects, the returned promise is rejected with the rejection reason.

                                                    Any exception happening in a .then-chain will propagate to nearest .catch handler.

                                                  • This extends .catch to work more like catch-clauses in languages like Java or C#.

                                                    Instead of manually checking instanceof or .name === "SomeError", you may specify a number of error constructors which are eligible for this catch handler. The catch handler that is first met that has eligible constructors specified, is the one that will be called.

                                                    This method also supports predicate-based filters. If you pass a predicate function instead of an error constructor, the predicate will receive the error as an argument. The return result of the predicate will be used determine whether the error handler should be called.

If value is a promise, the delay will start counting down when it is fulfilled and the returned promise will be fulfilled with the fulfillment value of the value promise.

Iteration happens serially. If any promise in the input array is rejected the returned promise is rejected as well.

                                                    The return values from the filtered functions are coerced to booleans, with the exception of promises and thenables which are awaited for their eventual result.

                                                    • Same as calling ``Bluebird.mapSeries(thisPromise, iterator)``. With the exception that if this promise is bound to a value, the returned promise is bound to that value too.

                                                    • Given an Iterable(arrays are Iterable), or a promise of an Iterable, which produces promises (or a mix of promises and values), iterate over all the values in the Iterable into an array and iterate over the array serially, in-order.

                                                      Returns a promise for an array that contains the values returned by the iterator function in their respective positions. The iterator won't be called for an item until its previous item, and the promise returned by the iterator for that item are fulfilled. This results in a mapSeries kind of utility but it can also be used simply as a side effect iterator similar to Array#forEach.

                                                      If any promise in the input array is rejected or any promise returned by the iterator function is rejected, the result will be rejected as well.

The new function will always return a promise that is fulfilled with the original functions return values or rejected with thrown exceptions from the original function. This method is convenient when a function can sometimes return synchronously or throw synchronously.

                                                      When this promise is is either fulfilled or rejected, the node callback will be called back with the node.js convention where error reason is the first argument and success value is the second argument.

                                                      The error argument will be null in case of success. If the callback argument is not a function, this method does not do anything.

                                                      Passing no value or a non-function will have the effect of removing any kind of handling for possibly unhandled rejections.

                                                      If the nodeFunction calls its callback with multiple success values, the fulfillment value will be an array of them.

                                                      If you pass a receiver, the nodeFunction will be called as a method on the receiver.

                                                      The promisified method name will be the original method name postfixed with Async. Returns the input object.

                                                      Note that the original methods on the object are not overwritten but new methods are created with the Async-postfix. For example, if you promisifyAll() the node.js fs object use fs.statAsync() to call the promisified stat method.

                                                      The promise's fulfillment value is an object with fulfillment values at respective keys to the original object. If any promise in the object rejects, the returned promise is rejected with the rejection reason.

                                                      If object is a trusted Promise, then it will be treated as a promise for object rather than for its properties. All other objects are treated for their properties as is returned by Object.keys - the object's own enumerable properties.

                                                      **Note** If you pass empty array or a sparse array with no values, or a promise/thenable for such, it will be forever pending.

For example, if an error is errbacked by a callback API promisified through undefined or undefined and is not a typed error, it will be converted to a OperationalError which has the original error in the .cause property.

                                                          OperationalErrors are caught in .error handlers.
