>What I miss in JS ecosystem is something single which solves all my problems. Like npm which can also build website, which can hot reload it for dev mode, which can autoformat my code with single blessed unconfigurable code style, which can lint it, which can run unit tests and so on. I don't want to spend a single second setting up my environment.
For this, you have Next.js/SvelteKit/Nuxt.js/whatever framework you prefer. For React in particular, Next.js with the default setup has all of these features but unit testing (there's a template for that, but it isn't as commonplace in frontend as it should be), and more such as server-side rendering, routing, data fetching, etc.
