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
