Install

Usage

Options

Options are passed as arguments to the new CopyPkgJsonPlugin({ options }) constructor and must be an object containing either a new key with an object containing the key/value pairs you wish to populate your new package.json with, a remove key with an array containing properties you want to remove from your existing package.json as strings and/or a replace key with an object containing the key/value pairs you wish to replace from your original package.json with. You may optionally pass in the absolute path string to the *directory* containing your package.json file. The plugin defaults to process.cwd() path. See the NOTE section below for more information on specifying the package.json directory path.

New

The new key expects an object with the standard package.json fields that you wish to be made available in your final bundle's package.json

Remove

The remove key expects an array with property names from your original package.json file that you wish to not be included in the copied package.json

Replace

The replace key expects an object with property names from your original package.json file that you wish to replace with different properties

By default this will merge keys by one level deep. So using the example above if your original package.json also included other scripts such as build command that script will be included in the copied package.json

If you do not want the existing keys to be merged and want to overwrite them you must add the the key to the remove option first

Note

This plugin assumes that your package.json is in the root directory of the node processes current working directory ie. process.cwd(). If your package.json is located elsewhere, you may optionally pass the absolute path of the directory where your package.json resides, as a second argument to new CopyPkgJsonPlugin constructor. NOTE: that you must pass in a first argument in order to pass in the context; if you wish to simply copy your existing package.json you can pass in an empty object :

If you wish to create a brand new package.json to be copied to the final dist bundle folder, pass an object with the key new which contains the key value pairs that you would like to be in your package.json: If you wish to simply copy your existing package.json your to the final dist bundle folder without any modifications and your package.json is located in the node processes current working directory ie process.cwd(), simply call the constructor without arguments and your package.json is located at the root :

If you which to remove an item from your existing package.json but not replace any just pass in this key:

And vice-versa if you wish to replace in an existing package.json but not remove any items:
