json.dump appears to add extraneous spaces before newline characters. By specifying the separators option, we can remove these whitespaces, reducing the diff noise.

onetime 
Ensure a function is only called once
When called multiple times it will return the return value from the first call.
Unlike the module once, this one isn't naughty extending Function.prototype.
Install
$ npm install --save onetime
Usage
let i = 0;
const foo = onetime(() => i++);
foo(); //=> 0
foo(); //=> 0
foo(); //=> 0
const foo = onetime(() => {}, {throw: true});
foo();
foo();
//=> Error: Function `foo` can only be called once
