I have downloaded Node JS on my WIN 10 system, I will perform the instructions in order to tell if I was successful running it.
I have no idea what I should do since I type the commands on the same folder of the cloned repo and only getting “Command not found” 
EDIT #2: After reading a bit about the package.json file, noticed we need some NodeJS modules to be installed first.
If we don’t install those modules, we will get error messages like this:
> fritzing-parts-api-client-js@0.2.0 pretest C:\Users\Manuel Bojato\Documents\AtomProjects\fritzing-parts-api-client-js
> make lint
"make" no se reconoce como un comando interno o externo,
programa o archivo por lotes ejecutable.

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm WARN Local package.json exists, but node_modules missing, did you mean to install?
EDIT #3: Looking deep at what I should install, I noticed there is a eslint package and also we need to install “make” for Windows in order to execute make commands as explained here.
