## What it is
nw-builder is an npm package and CLI tool for downloading, running, and building NW.js desktop applications for Linux, macOS, and Windows. It supports SDK/normal flavors, FFmpeg community builds, icon configuration, mirror downloads, and configuration via CLI, JavaScript API, or package. manifest.

## Use cases
- build an nw.js app for windows mac and linux
- package a node-webkit desktop application
- run my nw.js app in sdk mode for debugging
- add ffmpeg codecs to nw.js build
- download nw.js binaries from a mirror
- configure app icon and executable name for nw.js build
- integrate nw.js packaging into npm scripts or ci

## When to choose
- you are building desktop apps with NW.js and need cross-platform packaging
- you want a scriptable build step for NW.js in npm or CI pipelines
- you need community FFmpeg builds bundled with your NW.js app

## When to avoid
- you are building Electron or Tauri apps instead of NW.js
- you need a GUI-based packaging tool rather than CLI/API
- your project does not use Node.js
