On “How to learn npm and its "configs"?”
…out configs. It covers most used configs you will find but it's only skimming the surface, if you want to know what every option does then just go to documentation of library that uses it.
Personally I would recommend understanding .gitignore, .eslintrc.json (or eslint.config.js, depends which format you prefer), .prettier, tsconfig.json (great link to this video for basics again from fireship) and that's it. Even that much might be too much, framework usually generates good default configs and you shouldn't have to worry about them until you want to customize something…
