## What it is
nolyfill is a CLI tool that detects redundant JavaScript polyfill packages in a project's dependencies and replaces them with lightweight alternatives that use native platform implementations. It reduces node_modules size, speeds up package installation, and cuts disk usage for projects running on modern Node.js versions.

## Use cases
- reduce node_modules size in a JavaScript project
- speed up npm install / yarn install / pnpm install
- replace redundant es-shims polyfills with native implementations
- audit dependencies for unnecessary polyfill packages
- extend SSD lifespan by installing fewer files
- clean up polyfills targeting dead Node.js versions

## When to choose
- your project runs on Node.js 12.4.0 or newer with full ES2019 support
- you want to slim down node_modules and speed up installs
- your dependency tree pulls in polyfills from packages like eslint-plugin-import

## When to avoid
- your Node.js version is below 12.4.0
- you target environments without full ES2019 support (use core-js instead)
- you need guaranteed identical behavior to the original polyfill packages
