Simple utility to allow your module to be consumed with a callback or promise
Cater to callback and promise crowds.
Simple utility to allow your module to be consumed with a callback or promise. For Node.js and browsers.
If your module internally uses callbacks:
const { fromCallback } = require('catering')
const kPromise = Symbol('promise')
module.exports = function (callback) {
callback = fromCallback(callback, kPromise)
queueMicrotask(() => callback(null, 'example'))
return callback[kPromise]
}
If your module internally uses promises:
const { fromPromise } = require('catering')
module.exports = function (callback) {
return fromPromise(Promise.resolve('example'), callback)
}
Either way your module can now be consumed in two ways:
example((err, result) => {})
const result = await example()
When converting from a promise to a callback, fromPromise
calls the callback in a next tick to escape the promise chain and not let it steal your beautiful errors.
With npm do:
npm install catering
