f2e-server

f2e-server 2 (v2.20.13) is a front-end development server with built-in support for Less compilation, Babel transpilation, live reload, and middleware-based plugin architecture. It provides CLI commands for starting a dev server (`f2e start`), building to output (`f2e build`), and generating config files (`f2e conf`). Unlike heavyweight dev servers like webpack-dev-server, f2e-server focuses on simplicity and runtime-build with proxy capabilities. It ships with TypeScript type definitions but is primarily configured via CommonJS config files. The project has been updated infrequently (last release likely 2021-2022) and may lack modern features like HMR or ESM native support. The server auto-detects ports starting from 2850 and supports HTTPS and custom hostnames. It is suitable for lightweight front-end projects that need a quick development environment with minimal configuration.
