How does one go about building extensions

I have been here before, looking to build extensions, and share them. How does one do that?

@Gordon_Lu provides a nice guide here, using the niotron ide

I find using the RUSH builder much easier to use, working with the IntelliJ /idea IDE...


I dunno.... stupid question, maybe, but, while writing the source, I need not add the usual libraries &c within the js code?

Which builder are you using?

I went rush, after lots of reading and messing around with both, I get less errors with RUSH.
