For web apps: TypeScript with Next.js & Vercel

Next.js takes care of your full-stack web app (client routing, server APIs, the fuzzy world of SSR/SSG/ISR) plus your whole dev/prod build (zero-config React & TypeScript, minimal config ESLint & Prettier)

And Vercel deploys it as easily as `npx vercel --prod`, or just hooking your GitHub repo up to the project through their web UI so it deploys on push. Their integration will even show the deployment status for each commit, from within GitHub.

It's a delightfully streamlined process, and a suite of tools that all have large communities and rich ecosystems.
