Ask HN: Moving from tiny websites to serious tech skills?
12 by neonnoodle | 3 comments on Hacker News.
I’m a self-taught web coder and have made some small CRUD systems for very targeted tiny clients during my professional life. I have also made a few hobby sites for fun just for myself. I’d like to expand my skill set but I have trouble visualizing all the moving parts of a “big” web app and all the tools that go into it—when people talk about containers, or testing, or deploying such-and-such, I don’t have a clue. With HTML/CSS/JS, I can spin up a little demo to play around and learn on another personal/toy project, but how do I, as a solo person, learn about larger-scale technologies? I’m a visual artist and print-based technician so front-end would probably be the place to focus. Is there a recommended path for going from hobby projects & small sites to larger-scale best practices in React/another important platform?
