Hi Josue, a bit depends on the way you learn, I know some people that find pretty much all they need in https://www.freecodecamp.org/, additionally I post regular stuff about node here on medium and on http://livecodestream.dev/, but I’m not focused yet in building like a learning path.

Additionally, there are some great courses in udemy that you can get for around 10usd.

if you have specific questions don’t doubt in shooting me an email.
