Description

This package is a fork of Christoph von Gellhorn's package-json-cleanup-loader project. The exception option was added, allowing to pass to the package an array of keys that can be removed from the JSON file.

Did you know that when webpack includes package.json file in bundle this bundle can contain private information like installed module path? For example, lets install browserify:

$ npm install browserify
...
$ cat ./node_modules/browserify/package.json  | grep _
  {
    "_from": "browserify",
    "_id": "browserify@16.1.1",
    "_inBundle": false,
    "_integrity": "sha512-iSH21jK0+IApV8YHOfmGt1qsGd74oflQ1Ko/28JOkWLFNBngAQfKb6WYIJ9CufH8vycqKX1sYU3y7ZrVhwevAg==",
    "_location": "/browserify",
    "_phantomChildren": {},
    "_requested": {
      "type": "tag",
      "registry": true,
      "raw": "browserify",
      "name": "browserify",
      "escapedName": "browserify",
      "rawSpec": "",
      "saveSpec": null,
      "fetchSpec": "latest"
    },
    "_requiredBy": [
      "#USER",
      "/"
    ],
    "_resolved": "https://registry.npmjs.org/browserify/-/browserify-16.1.1.tgz",
    "_shasum": "7905ec07e0147c4d90f92001944050a6e1c2844e",
    "_spec": "browserify",
    "_where": "C:\\work\\json-cleanup-loader",
  }

This package by default removes all values for which keys start with _ or the values passed in options.

• options
  • only: removes all values and keeps only the keys declared within the array of this option.
  • except: keeps all values except the keys declared within the array of this option.

Please note: Options are not concurrent. The predominate option is defined in this order: only, exception, and default.

How I can use this package?

Installation

npm install --save-dev package-json-remove-key

Usage

CLI

webpack --module-bind 'path/to/package.json=package-json-remove-key'

Change webpack config

default option:

module.exports = {
  module: {
    rules: [
      {
        test: /package\.json$/,
        use: {
          loader: "package-json-remove-key"
        }
      }
    ]
  }
};

only option:

module.exports = {
  module: {
    rules: [
      {
        test: /package\.json$/,
        use: {
          loader: "package-json-remove-key",
          options: {
            only: ["version", "name", "otherParam"]
          }
        }
      }
    ]
  }
};

except option:

module.exports = {
  module: {
    rules: [
      {
        test: /package\.json$/,
        use: {
          loader: "package-json-remove-key",
          options: {
            except: ["_where", "_resolved", "otherParam"]
          }
        }
      }
    ]
  }
};

Warning: If the error message "You may need an appropriate loader to handle this file type" occurs during the bundle build process, it will be necessary to define in the webpack rules the package that will load the JSON files. Install the json-loader package and use the loading rule to the webpack configuration file:

npm install --save-dev json-loader

module.exports = {
  module: {
    rules: [
      {
        test: /\.json$/,
        use: {
          loader: "json-loader",
        },
      },
    ],
  },
};
