NPMprune

npmprune.sh is an lightweight script designed to clean up your node_modules directory by removing unnecessary files like Markdown, doc and config files.

It helps in reducing the overall size of node_modules, optimizing storage space, and speeding up deployments, especially in containerized environments.

By detecting NODE_ENV, it can perform a more aggressive cleanup, tailored for production builds such as in Docker containers.

Install

wget -O /usr/local/bin/npmprune https://raw.githubusercontent.com/xthezealot/npmprune/master/npmprune.sh && chmod +x /usr/local/bin/npmprune

Usage (Unix/Linux)

1. Ensure you have execution permissions: chmod +x npmprune.sh
2. Run the script in your project directory: ./npmprune.sh

Usage (Windows)

1. Open PowerShell.
2. Navigate to your project directory.
3. Run the script: .\npmprunewin.ps1

The PowerShell version, npmprunewin.ps1, performs similar functions as the shell script but is tailored for Windows environments. It leverages PowerShell commands to efficiently clean the node_modules directory, taking into consideration the Windows filesystem and permissions.

Production mode

If the NODE_ENV environment variable is set to production, NPMprune performs a more extensive cleanup by also removing type definitions.
