Having been indirectly convinced to post my approach to coding in ServiceNow by someone who knows far more than I do, I've decided to make this an initial of what I hope to turn into a series of posts revealing my coding practices. The idea is rooted around scale-able, less brittle, and easily maintainable code base. More importantly, have others see aspects of my code that I am not seeing.
The first approach is using an IIFE to automatically access objects within an execution context. Meaning that if A spawns B, then B has access to A, then C to B and A, etc.
Script Include as Module Pattern to separate concerns; each concern separated as IIFE that itself is a Revealing Module
var MyModule = {
namespaceone : ( function(current, previous) {
//code logic here such as.
function doSomePreSaveDataManipulation(){
current.short_description = "my short description";
}
var publicAPI = {
somePreSaveDataManipulation : doSomePreSaveDataManipulation();
}
return publicAPI;
})(current, previous);
};
The blow snippet can be a Business Rule, a Workflow Activity, etc. Currently, I'll go with a before business rule.
(function executeRule(current, previous){
/*
access name space by reference. because JS behavior, objects found in the functions execution context will be automatically available to "children".
*/
var manipulate = MyModule.namespaceone;
manipulate.somePreSaveDataManipulation();
})(current, previous);
