Promises/A+ for NoFlo
Provide Promises/A+ handling in NoFlo by wrapping around the NPM module promise. It doesn't make sense to create promises in NoFlo because NoFlo itself is the framework to manage your program's flow. Therefore, this package simply provides ways to manipulate existing promises used in parts of your program that are not within NoFlo.
Installation
npm install --save noflo-promise
Usage
Listed in-ports in bold are required and out-ports in bold always produce IPs.
From
Wrapper around Promise#from(1) to convert a non-promise into a promise.
In-Ports
- IN: The value to convert
Out-Ports
- OUT: A promise
Then
Accept a promise, set it to forward the passed value to SUCCESS upon fulfillment of the promise or to FAILURE upon rejection, then forward the promise onto OUT if it's attached.
Each passed parameter is forwarded as an IP. For instance, a promise that would look in procedural JS:
promise.then(function(a, b, c) {
... would be translated as three IPs of the values of a, b, and c.
In-Ports
- IN: A promise
Out-Ports
- OUT: A promise
- SUCCESS: Forwarded the passed value on fulfillment
- FAILURE: Forwarded the passed value on rejection
