Quick Answer
Full Stack Open Parts 3 to 5, from the University of Helsinki, is the best free Node.js course if you already know JavaScript. It covers Express, MongoDB, testing, JWT auth, and deployment, and the certificate is free. If you learn best by building projects without a template, pick The Odin Project's NodeJS path instead. If you want a free certificate and more structure to start, do freeCodeCamp's Back End Development and APIs certification first. Not comfortable with JavaScript yet? Work through /learn/javascript before any of them.
