wtf is next-trpc-capacitor?

This is a template project that helps you build a mobile app and a web app from the same codebase. It combines Next.js (a web framework), tRPC (a tool for building type-safe APIs), and Capacitor (which lets you run web code on phones as native apps). The benefit is that you write your code once and deploy it everywhere, as a website, an iOS app, and an Android app, without duplicating your work. The project is structured so that your backend API runs on Vercel (a hosting platform), and both your web interface and mobile apps talk to that same API. When you're developing locally, you can test everything together. When you're ready to deploy, you push the web version to Vercel, and you can simultaneously build mobile versions for iOS and Android using Capacitor. The setup automatically detects which environment you're running in (local development, web, or mobile) and adjusts the configuration accordingly. You'd use this if you want to launch both a website and mobile apps but don't want to maintain separate codebases. For example, a task management app, a note-taking tool, or a social platform can run identically on the web and on phones. The template handles the plumbing so you focus on features instead of juggling multiple projects. The README doesn't go into detail about what each technology does, but the project is bootstrapped from a popular starter kit that already has these tools configured to work together. The main tradeoff here is complexity: you're bringing together several technologies, so getting started requires understanding how to configure environment variables and build processes for different targets. But once set up, you get the benefit of writing logic once and deploying to all platforms.
