The best advice is: Read How to Write Go Code
https://golang.org/doc/code.html
and stick to it.
Yes, modules are the thing to be used
1. But naming a module "src" is begging for trouble.
Name your module either something like
julesgocode.org/firsttry
or maybe
github.com/<yourgithubnamehere>/firsttry
2. If your package jsonstuff lifes in module
"julesgocode.org/firsttry" then its import path
is "julesgocode.org/firsttry/jsonstuff".
One thing a lot of Go newcomers seem to have trouble
with is the fact that the go tool works best on packages
and _not_ on files: You dop not import files and you do
not run files and you do not test files. Files contain the
sources but are basically uninteresting: Focus on
packages (and modules). Packages life in modules.
Modules have a _sensible_ name or might even point
directly to your revision control system. Packages
are named like the filesystem folder the are contained.
Importing happens by "full qualified import path", i.e.
<full-name-of-module>/<relative-FS-path-inside-module>
This is not the whole truth but the basic essence of how
you should work.
