Readme

copy-node-modules - fast deploy Node.js modules to distination folder

Copy all modules listed in 'dependencies' or 'devDependencies' field of package.json to destination folder.

The procedure:

  1. Read package.json from source directoy, and read 'dependencies' or 'devDependencies' field.
  2. Search existed modules in source directory, and search all dependencies.
  3. Copy all modules to destination directory.

The modern applications use lots of modules, each module depends on more modules, results hundreds of modules need to be installed when typing npm install. When you want to pack/deploy your application to a folder which contains all needed modules, this module will help you to save time from slow npm install

It will save you a bunch of time to deploy stand-alone application from existed development directory, no need to fetch all modules from remote repository.

Installation

npm install copy-node-modules --save-dev
