## What it is
FIS3 is a frontend engineering build system from Baidu's FEX team that handles compilation, performance optimization, resource loading, dependency analysis, and deployment of static assets. It uses a CSS-like configuration syntax (fis-conf.js) with a plugin ecosystem for parsing, optimizing, and packaging JS, CSS, and images.

## Use cases
- build and optimize a frontend project's js, css, and images
- manage static resource loading with dependency analysis
- bundle modular JavaScript with AMD/CMD/CommonJS support
- generate CSS sprites and inline assets automatically
- preview a frontend project locally with a dev server and live reload
- deploy the same codebase to different server directory layouts
- integrate static asset management with PHP, Java, or Node backends

## When to choose
- maintaining a legacy frontend codebase already built with FIS/FIS3
- you need whole-site static resource management tied to backend templates
- you prefer declarative glob-based build configuration over bundler code

## When to avoid
- starting a new modern project - webpack, Vite, or Rollup have larger ecosystems
- you need active community support or frequent updates
- your toolchain relies on modern ES modules and current Node versions

## Facets
