promise_fns

Promise utility functions for Deno.

Inspired by the sindresorhus promise-fun collection. Parity with the node promise-fun library is not guaranteed.

Features:

each function is independently importable
all typesafe, type reflecting APIs
debuggable. simplified source, named functions (so your stack trace is legible!)

usage

You can import any individual function as follows:

import fn from "https://deno.land/x/promise_fns/src/FUNCTION_NAME.ts";
fn(...)

All functions are listed in the functions table.

A full example:

import delay from "https://deno.land/x/promise_fns/src/delay.ts";
const delayedTwo = await delay(100, 2);
console.log(1 + delayedTwo); // 3

function	description	links
all	resolve an eager or lazy collection of promises	src test
catchIf	Conditional promise catch handler	src test
delay	create a promise that sleeps for some milliseconds then resolves	src test
delayReject	create a promise that sleeps for some milliseconds then rejects	src test
if	Conditional promise chains	src test
map	maps a collection into a new collection asynchronously	src test
promisify	converts a node-style callback function into a promisified function, returning the result after `err`, per `(err, result) => void`	src test
promisifyMulti	converts a node-style callback function into a promisified function, returning all results after `err`, per `(err, ...results) => void`	src test
props	maps a { key:promise } mapped collection to a { key:resolved-promise } mapped collection	src test
queue	creates a queue that allows users to add work. queue resolves when no work is outstanding	src test

More functions are on their way.
