aside from bringing a msg into a function node and sending a msg out at the end of a function, how can i call a function from within a function? in the middle of my function i need to perform some numerical computes that i can either copy and paste the same formulas throughout my functions or i can…

This did it, I can work with this [image] Use function multiple times General One approach would be to use the global.set() with the memory module. store your function in a global variable: global.set('sum', function(a, b) { return a + b; }, 'memoryOnly'); use y…

A subflow is wired the same as any node. The beauty of using a subflow is your function code exists only once (i.e. not an unmanageable 10 copy/paste affair). Pass your data to input of subflow, get processed data out of its output(s)

If you want to stay totally inside the one function you can just declare an internal function just like in any other piece of javascript. var myfunc = function(foo) {... style then call it from within your function. Things to note are that the whole function is instantiated whenever a msg arrives…

Thank you dceejay, i'm not sure where i read it, but is it possible to declare a function as you stated as a 'global variable' where i change a memory config in settings.js?

You can declare functions in global. But it isn't wise to do that within a flow, only from settings.js That is because not all var handlers may support serialisation of functions. But setting in the globals section of settings.js should always work. You can then use `global.get('myfnName') in a fu…

do i simply add the function declaration at the end of the settings file? function myFunction(n1,n2) { return n1 + n2; } var input = msg; var off = input.payload.foff; var on = input.payload.fon; var count = 1; var input_off_float = flow.get(["input_off_float"]); va…
