Sanity check for Wifi and http modules please getIP getAPIP

I need to edit/debug an existing online module using the online WebIDE.

Do you mean debugging part of the Web IDE, or a module running on Espruino?

Given the rest of this post I'd assume you mean a module running on Espruino. You can't 'map' a local file at the moment, nor can you use 'Chrome Developer tools' (those are for Chrome).

The easiest way to do it is to add:

Modules.addCached("mymodule",function() { 
 // modulecode
});

to the front of the source file you upload. You can then view/modify the code pretty quickly.

On the online IDE you can also upload directly to a storage file called modulefile, and can set the 'Load after saving' option to 'default' - you can then work directly with the module you're interested in.
