- # call-me-maybe [](https://github.com/limulus/call-me-maybe/actions/workflows/continuous-release.yaml)
- Let your JS API users either give you a callback or receive a promise.
- ## Usage
- ```javascript
- var maybe = require("call-me-maybe")
- module.exports = function asyncFunc (cb) {
- return maybe(cb, new Promise(function(resolve, reject) {
- // ...
- }))
- }
- ```
- ## API
- ### maybe(cb, promise)
- 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:
- - If `promise` is fulfilled, then it is called with the result of the promise: `cb(null, result)`
- - If `promise` is rejected, then it is called with the rejection error: `cb(err)`
- If `cb` is falsey, then `promise` is returned.
