Npm-hardlink NPM

npm-hardlink

Hard link npm packages between projects.

This project was developed to fix React hook issues caused by npm link.

Features

Super simple to use
Uses hard links vs symlinks
Uses npm’s official npm-packlist to establish which files to hard link
Uses trusted dependencies (chokidar, commander, fs-extra, etc…)
Very light codebase to audit (less than 150 lines of code)
Written in TypeScript

Installation

npm install -g npm-hardlink

Usage

$ npm-hardlink -h

  --install-deps        install package dependencies
  --install-deps-prod   install package production dependencies

Example

In following example, we are developing a React component called react-cms (packaged as @sunknudsen/react-cms) that we are planning to publish to npm.

Before publishing @sunknudsen/react-cms, we would like to import component from project called sunknudsen-website to see if everything is working (we tried npm link and things were broken).

$ pwd
/Users/sunknudsen/Code/sunknudsen/react-cms

$ npm-hardlink --dest /Users/sunknudsen/Code/sunknudsen/sunknudsen-website --install-deps --watch
