create-thenable

create-thenable

Create a thenable for a given Promise

Install

$ npm install --save create-thenable

Usage

var thenable = require('create-thenable')(require('bluebird'))
return thenable.catch(errHandlers).then(handler)

The returned thenable has a then method that creates a new promise. It also proxies methods from the prototype and guarantees the presence of catch and finally. When these proxied methods are called, they call then to create the promise and then call the method on the result. That way you can do this:

var thenable = createThenable(require('bluebird'), function () {
  resolve('foo')
})


thenable.tap(function () {
  console.log('succeeded')
})
.then(function (value) {
  assert(value, 'foo')
})

thenable isn't a true Bluebird Promise but you can still trigger its methods as if it were.
