Medusa’s community plugin, Medusa Extender, provides multivendor support and full customization capabilities to create a custom ecommerce website.

In the previous parts of this series, you learned how to build a marketplace using Medusa and Medusa Extender. You associated users, products, and orders to a store.

Medusa is open-source project which provides many powerful e-commerce functions and extensions as Shopify. I follows the article for multi-vendor marketplaces shared from Shahed Nasser who is very outstanding engineer. But it only shows for backend modification with medusa-extender, not include the change of frontend side.

The Medusa server uses the method [buildQuery_](https://github.com/adrien2p/medusa-extender/releases/tag/v1.7.0) in OrderService to build the query necessary to retrieve the orders from the database. You’ll be overriding the OrderService, and particularly the buildQuery_ method to add a selector condition for the store_id if there is a currently logged-in user that has a store.

Medusa on steroid, take your medusa project to the next level with some badass features 🚀 The extender provides an out-of-the-box application architecture which allows developers and teams to create highly testable, scalable, loosely coupled, and easily maintainable applications. In also increase medusa extensibility and customisation for special use cases. It comes with handy decorators approach to increase the DX and full typings support for easier development. It is a complement to medusa but not a replacement 🚀
