Built-in JS modules

Simply stick the JS modules you want in this directory, then modify the boards/BOARDNAME.py file so it includes a line that sets JSMODULESOURCES:

info = {
 ....
 'build' : {
   ....
   'makefile' : [
     ....
     'JSMODULESOURCES+=libs/js/YOUR_MODULE.min.js',
   ]
 }
};

or add them as prefix to make

JSMODULESOURCES=libs/js/YOUR_MODULE.min.js make

Then when you rebuild, require("YOUR_MODULE") will magically pull in your module.

Notes

• Until referenced, modules use NO RAM
• Once referenced, the JS code in a module will be executed (from Flash).
• Every function declared in the module's root scope will take up some RAM
• However the code inside that function will be kept in Flash memory, so won't take up RAM.
