node-utils

Generic node utils I wish I had in apps when developing various apps

Functions

wait

Wraps the set timeout function and returns a promise that resolves when the timeout finishes.

wait(1000).then(() => console.log('Done!'));

waitAndPass

Wraps the wait function and returns a function that returns promise that resolves when the timeout finishes with the information passed to the wrapper function.

waitAndPass(1000)('Done!').then((data) => console.log(data));
Done!

The main intention is to allow for chaining in promises more cleanly

https.get(dataUrl)
.then(waitAndPass(500))
.then(render)

wrapPromise

Wraps the promise passed to it such that it always resolves to an array in a similar manner to the old callbacks

let [err, data] = await wrapPromise(Promise.resolve('Done!'));

let [err, data] = await wrapPromise(Promise.reject('Done!'));

Tests
