Repackify

Repackify is a new package.json repackager that offers a suite of features for managing your package.json files. It provides functionalities such as refactoring, backing up package.json files, implementing environment variables within package.json, and more. The package is designed to be extensible, with more features planned for future releases.

Installation

To install Repackify, use the following command:

npm install repackify

Features

• Refactoring

  Repackify allows you to refactor your package.json files according to a provided configuration. This includes adding, removing, replacing properties, replacing text, and executing custom operations.

  The configuration file should be named repackify.config.js and should be placed in the root of your project. Here is an example of a configuration file:

  module.exports = {
    // This will add the author property to the package.json file
    add: {
      author: "Nameer Haider",
    },
  
    // This will remove the devDependencies supertest and jest from the package.json file
    remove: ["devDependencies"],
  
    // This will replace the scripts property with the provided object
    replace: {
      scripts: {
        "start": "node index.js"
      }
    },
  
    // This will replace the text "packifyr" with "repackify" in the package.json file
    replaceText: [{ text: 'packifyr', replace: 'repackify' }],
  
    // This will execute a custom operation on the package.json file and then save the returned version
    customOperation: [
      (packageJson) => {
        packageJson.name = 'repackify';
        return packageJson;
      },
    ],
  };

  This can be done inside the package.json file as well, but it is recommended to use a configuration file for better organization and readability.

  "repackify": {
    "remove": ["description", "author"]
  },

• Backup

  provides a backup feature that allows you to create a backup file of your package.json file.

• Restore

  Repackify allows you to restore your package.json file from a backup file.

• Environment Variables

  Repackify allows you to implement environment variables within your package.json file, simply set the environment variable key anywhere in the package.json file and it will be replaced after running the refactor command.

  "scripts": {
    "start": "start something --mode !{ENV_MODE}",
  },
  

  and then

  repack refactor

CLI Commands

Repackify provides a command-line interface for managing package.json files. Here are the available commands:

repack backup

This command backs up the package.json file and save it inside package.backup.

repack backup

repack restore

This command restores the package.json file from the backup file and then delete it.

repack restore

repack refactor

This command refactors the package.json file using the provided configuration. It accepts two optional parameters:

• --env or -e: Path to the base .env file.
• --extra_env or -ee: Used to set extra .env files (e.g. -ee .env,.dev.env).

repack refactor --env .env --extra_env .env,.dev.env

Using With NPM Pre & Post Scripts

In your package.json file, you can define pre and post scripts for certain NPM commands. These scripts will automatically run before and after the specified command. For example, you can define a preinstall script to refactor your package.json file before installation and a postinstall script to restore it after installation, and the same with publish command.

// package.json

"scripts": {
  "preinstall": "repack refactor",
  "postinstall": "repack restore",
  "Prepare": "repack refactor",
  "postpublish": "repack restore"
}
