Introduction

Medusa.js is an open-source e-commerce framework built with Node.js.

It is aimed at companies that need flexibility in building modern online stores.

Why can we like Medusa? The API-first approach makes it possible to build an online store with virtually no limitations in terms of functionality, layout, or behavior.

And what is great about it?

Security and performance do not drop, and we can gain a lot.

I really liked the concept in the approach to e-commerce. At Codee we have been building websites for a few years using the Jamstack approach, where headless plays an important role.

Brief history

Medusa.js was created by Sebastian Rindom, Oliver Juhl, and their team in 2021. The creators had previously worked on e-commerce projects and noticed many problems with existing platforms, such as limited customization, difficulty integrating modern technologies, and the high complexity of implementations.

Today we already have version 2.0, which introduced many improvements. I will write more about it in the next articles, sharing knowledge and my thoughts.

Why was a new e-commerce platform created?

Solutions like Magento or Shopify limit developers through a monolithic structure or a closed ecosystem. The creators wanted to build a solution that would be modular and open, and that would meet the modern approach to building online stores. So what is it and what does it mean?

How does it work?

In short, headless commerce is the separation of the user interface from the content management system and e-commerce logic, such as order management, payments, and products.

What are its key elements?

1. Back end - This is where all data, business logic, and e-commerce functions are stored (products, orders, users).
2. API - Communicates with the front end, delivering data in JSON or GraphQL format.
3. Front end - Can be any technology. We can choose from solutions such as React.js and its framework Next.js, or Vue.js and its framework Nuxt.js.

What are the differences between Medusa.js and traditional e-commerce solutions?

In the traditional approach, the front end and back end are tightly coupled, which makes the store less flexible. You could also say it is harder to develop.

If we separate them, traffic is directed to two separate instances. Then even when traffic is high, or in the worst case the back end goes down, the user can still browse the online store. The same works the other way around: the front end can stop working while nothing happens to the back end.

One of the main advantages of Medusa.js is the separation of key elements. With this approach we can independently develop new features on each side.

Back-end independence introduces additional possibilities because data is fetched through the API.

In my opinion, an interesting example is when we run a blog on the website and want to display products from the store so the user can add a product directly from the blog and be redirected to the store, while adding the selected product to the cart. Thanks to this, we can capture user interest much earlier and increase the probability of purchase.

In summary...

In my view, today it is a platform that is rapidly gaining popularity among companies that need scalable and flexible e-commerce solutions. Thanks to its openness, Medusa.js is currently seen as one of the best alternatives to closed systems such as Shopify or Magento.
