Medusa JS Client

The Medusa JS Client provides easy access to the Medusa API from a client written in TypeScript. This reference guides you to learn what methods the client has and how you can use them.

This client can be use as an alternative to directly interacting with the REST APIs.

Installation

To install the Medusa JS Client run the following command:

npm install @medusajs/medusa-js

How to Use this Reference

You'll find in the sidebar of this reference names of different resources. These resources are properties in the medusa instance you initialize and you can access them directly using the instance. Then, you'll be able to access the methods or nested resources within those resources.

For example, to create a new customer you can access the create method under the customers property of your client:

import Medusa from "@medusajs/medusa-js"

const medusa = new Medusa()

// use method
medusa.customers.create({
// data
})

The customers resource also has another resource addresses nested inside it with its own method that you can access similarly:

medusa.customers.addresses.addAddress({
// data
})

Authentication

Authentication can be achieved in two ways using the medusa-js client: either by utilizing API keys or by using cookie based authentication. Each method has its own unique use case.

Using API keys

API keys can only be used for admin functionality in Medusa since only users of the admin system have API keys. Refer to the Configuration section to learn how to add the API key to requests.

Using cookies

Authentication using cookies is done automatically by Axios when authenticating using the auth endpoints. After authentication, all subsequent calls will be authenticated.


Configuration

Initialize with config object

The package can be initialized with several options:

const medusa = new Medusa({
maxRetries: 3,
