Let your JS API users either give you a callback or receive a promise.
var maybe = require("call-me-maybe")
module.exports = function asyncFunc (cb) {
return maybe(cb, new Promise(function(resolve, reject) {
// ...
}))
}
If the callback cb
is truthy, returns undefined
and will call cb
when promise
is settled. The parameters passed to cb
are standard error-first:
promise
is fulfilled, then it is called with the result of the promise: cb(null, result)
promise
is rejected, then it is called with the rejection error: cb(err)
If cb
is falsey, then promise
is retuned.
