How to Write Global Functions in Postman

Question

I need help writing a common function to use across a collection of requests which will help with building a framework.

I have tried using the below format

Answer 1

You can declare a global function by assigning this function into a collection, environment or global variable as follows:

• Create a collection variable, i.e. global_func
• In the variable value write this code,

(number)=> { return number * number }

to reuse this function elsewhere in your collection

let numberSquared = eval(pm.variables.get('global_func'))(5)

now, numberSqaure variables has a value of 25

================================

if you need to declare a function library: you can create a collection variable and assign it this piece of code:

({
    print:function() {
        console.log('hello Postman')
    },
    squared:function(number) {
        return number * number
    }
})

Note: the functions have been enclosed with parentheses

to reuse this library:

let lib = eval(pm.variables.get('global_func'))
lib1.print()
console.log(lib1.squared(4))

Good luck :)
