Don't fall for the "JS ecosystem" trap and use sane tools. If a floobergloob requires you to add a floobergloob.config.js to your project root that's a very good indicator floobergloob is not worth your time.

The only boilerplate files you need in a JS repo root are gitignore, package.json, package-lock.json and optionally tsconfig if you're using TS.

A node.js project shouldn't require a build step, and most websites can get away with a single build.js that calls your bundler (esbuild) and copies some static files dist/.
