## What it is
Modern.js is a progressive React web framework from ByteDance built on the Rust-based Rspack/Rsbuild toolchain. It provides file-based nested routing, SSR/SSG/RSC rendering modes, integrated BFF development, and built-in CSS solutions with zero-to-full configurability.

## Use cases
- build a React app with server-side rendering
- create a React app with file-based routing
- build a full-stack React app with a BFF layer
- generate a static site from React components
- speed up React builds with a Rust bundler
- build a React app with React Server Components
- scaffold a production React web application

## When to choose
- you want an all-in-one React framework with SSR, SSG, and RSC support out of the box
- you need faster build times via Rspack/Rsbuild instead of webpack
- you want integrated BFF development in the same project as the frontend
- you are building React applications at scale, especially in a ByteDance-style ecosystem

## When to avoid
- you prefer the larger ecosystem and community of Next.js
- your project is not React-based
- you need a minimal setup without framework conventions
- you rely on plugins or tooling specific to Vite or webpack ecosystems
