API

run(main, drivers)

Importing

import * as Motorcycle from '@motorcycle/core'

Motorcycle.run(main, drivers)

Takes a main function and circularly connects it to the given collection of driver functions.

The main function takes an object of sources as input. Sources are the outputs from the various drivers. To complete the cycle, main should return a sinks object, which is a mapping of return values from the program to the drivers, i.e., inputs to the drivers, usually Observables/Streams.

Arguments:

main :: Function - a function that takes sources as input and outputs a collection of sinks Observables/Streams.

drivers :: Object - an object where keys are driver names and values are driver functions.

Return:

(Object) an object containing sources, sinks, and dispose() that can be used for debugging or testing.

sources :: Object<most.Stream> - The collection that is passed to your main function. The output of the drivers passed to run()

sinks :: Object<most.Stream> - The collection that is returned from your main function. The input to the drivers.

dispose :: Function - A function that will dispose of streams from sinks and sources.
