Node.js - TriggerFlow
A simple library used to conditionally trigger methods.
Why?
Some patterns necessitate having triggers. For example, consider walking a directory tree:
What if when the end
event is emitted, some file processing is still occurring? And let's say that the other part of your program needs this file processing to be completed, what do you do?
Install
npm install triggerflow
Usage
Revisiting the previous example, you can solve this problem quite easily with a trigger. A trigger can be thought of as a switch that fires a method when some conditions have been met. More specifically in the case of triggerflow
, when the conditions meet a base condition.
In triggerflow
, base conditions are when a boolean
is true
and when a number
is 0
.
Example:
var trigger = ; var finishedTrigger = processing = 0;
The trigger is only fired and thus moveToNextPartOfProgram()
is called when processing
is 0
and done
is true
.
