Plugins

In this document, you’ll get an overview of plugins in Medusa, where to find them, and how to install them. If you want to learn how to create a plugin, check out this guide instead.

Overview

Medusa was built with flexibility and extendability in mind. All different components and functionalities in Medusa are built with an abstraction layer that gives developers the freedom to choose what services they want to use or how to implement a certain component in their ecommerce store.

Developers can use plugins to take advantage of this abstraction, flexibility, and extendibility. Plugins allow developers to implement custom features or integrate third-party services into Medusa.

For example, if you want to use Stripe as a payment processor in your store, then you can install the Stripe plugin on your backend and use it.

An alternative approach is developing a custom way of handling payment on your ecommerce store. Both approaches are achievable by either creating a plugin or using an existing plugin.

Plugins run within the same process as the core Medusa backend eliminating the need for extra backend capacity, infrastructure, and maintenance. As a result, plugins can use all other services as dependencies and access the database.

Plugins can contain customizations to the Medusa backend or the admin dashboard.

Using Existing Plugins

Official Plugins

Medusa has official plugins that cover different aspects and functionalities such as payment, Content Management System (CMS), fulfillment, and notifications. You can check out the available plugins under the Plugins section of this documentation.

Tip

To feature your plugin in our repository, you can send a pull request that adds your plugin into the packages directory. Our team will review your plugin and, if approved, will merge the pull request and add your plugin in the repository.

Community Plugins

You can find community plugins by searching NPM for the medusa or medusa-plugin keywords.

You can also check our Plugin directory for a list of existing Medusa plugins.

How to Install a Plugin

To install an existing plugin, in your Medusa backend run the following command:

• npm
• Yarn
• pnpm

npm install <plugin_name>

yarn add <plugin_name>

pnpm add <plugin_name>

Where <plugin_name> is the package name of the plugin. For example, if you’re installing the Stripe plugin <plugin_name> is medusa-payment-stripe.

Plugin Configuration

If you’re installing an official plugin from the Medusa repository, you can find in its README.md file a list of configurations that are either required or optional. You can also refer to the documentation related to that plugin for more details on how to install, configure, and use it.

For community plugins, please refer to the installation instructions of that plugin to learn about any required configurations.

enableUI Plugin Option

All plugins accept an option named enableUI. This option allows you to disable admin customizations from appearing in the admin dashboard.

Note

enableUI's default value is false if not provided by the plugin users. This means that it must be enabled manually in a plugin's configuration for the customizations to appear in the admin dashboard.

You can set the enableUI value by passing it as part of the plugin's configurations:

medusa-config.js

const plugins = [
  // ...
  {
    resolve: `medusa-plugin-custom`,
    options: {
      // other options
      enableUI: true,
    },
  },
]
