Creating and publishing a standalone plugin for MedusaJS involves several steps. Below is a comprehensive guide to help you achieve this:

Steps to Create and Publish a New Plugin in MedusaJS

1. Set Up the Environment

Ensure you have the necessary tools installed:

• Node.js (>=16.x)
• npm or yarn
• A MedusaJS project for testing the plugin

2. Create a New Plugin Project

1. Initialize a new Node.js project:

   mkdir medusa-plugin-my-plugin
   cd medusa-plugin-my-plugin
   npm init -y

Replace medusa-plugin-my-plugin with your plugin name.

2. Install Medusa dependencies:

   npm install @medusajs/medusa

3. Add a plugin structure:
   Create the necessary files for your plugin:

• index.js: The entry point for your plugin.
• src: Directory for core plugin logic.
• package.json: Contains metadata about your plugin.

3. Implement Plugin Logic

1. Define the plugin interface:
   Medusa plugins are initialized through the register function and can use hooks to extend or modify Medusa functionality.
2. Example index.js file:

   class MyPlugin {
     constructor({ options }) {
       this.options = options;
     }

     load(container, options) {
       console.log("MyPlugin loaded with options:", options);
       // Add custom logic here
     }
   }

   module.exports = MyPlugin;

3. Export the plugin in package.json:

   {
     "name": "medusa-plugin-my-plugin",
     "version": "1.0.0",
     "main": "index.js",
     "medusa-plugin": true,
     "description": "A custom MedusaJS plugin.",
     "dependencies": {
       "@medusajs/medusa": "^1.8.0"
     }
   }

4. Test Your Plugin Locally

1. Link your plugin (to test in an existing Medusa project):

   npm link

In your Medusa project, link the plugin:

   npm link medusa-plugin-my-plugin

2. Add the plugin to the Medusa config:
   In your Medusa project’s medusa-config.js:

   const plugins = [
     {
       resolve: "medusa-plugin-my-plugin",
       options: {
         // Plugin-specific options
       },
     },
   ];

   module.exports = { plugins };

3. Run the server:

   npm run develop

Confirm your plugin’s functionality is working.

5. Publish the Plugin to npm

1. Update the package.json for publishing:
   Ensure you have a unique package name, a meaningful description, and a valid author field.
2. Login to npm:

   npm login

3. Publish your plugin:

   npm publish --access public

6. Share the Plugin

• Once published, developers can install your plugin via:

  npm install medusa-plugin-my-plugin

• Add a README file to your repository to document how to install and use your plugin.

7. (Optional) Open Source on GitHub

1. Create a GitHub repository for your plugin.
2. Add your plugin’s source code and include documentation.
3. Add a license to your repository.

8. Submit to Medusa Plugin Directory

Medusa has a plugin directory for sharing community plugins. Follow the Medusa guidelines to submit your plugin.

By following these steps, you’ll create a reusable, standalone plugin for MedusaJS that can be published to npm and shared with the community.
