Programming Wirelessly

Hi... Yes, sending the code string to eval is probably the best method. Obviously if you're using some kind of non-secured system you might want to think a bit about security though!

Executing something using eval can actually alter the state of the root scope (the value doesn't have to be returned), so you can actually just do:

eval("function foo() { console.log('foo'); }");
foo();

The other option if you want something more physical is to save the following code:

function onInit() { eval(require("fs").readFile("boot.js"); }

And then to put any code you have on the SD card.
