## Prerequisites
### Medusa Components
It's assumed that you already have a Medusa server installed and set up. If not, you can follow our [quickstart guide](../../quickstart/quick-start.md) to get started.
It is also assumed you already have a storefront set up. It can be a custom storefront or one of Medusa’s storefronts. If you don’t have a storefront set up, you can install either the [Next.js](../../starters/nextjs-medusa-starter.md) or [Gatsby](../../starters/gatsby-medusa-starter.md) storefronts.
### JS Client
This guide includes code snippets to send requests to your Medusa server using Medusa’s JS Client and JavaScript’s Fetch API.
If you follow the JS Client code blocks, it’s assumed you already have [Medusa’s JS Client installed](../../js-client/overview.md) and have [created an instance of the client](../../js-client/overview.md#configuration).
### Previous Steps
This document assumes you’ve already taken care of the add-to-cart flow. So, you should have a [cart created](https://docs.medusajs.com/api/store/#tag/Cart/operation/PostCart) for the customer with at least [one product in it](https://docs.medusajs.com/api/store/#tag/Cart/operation/PostCartsCartLineItems).
You can learn how to implement the cart flow using [this documentation](../../guides/carts-in-medusa.mdx).
To follow along with this tutorial, you can make use of the [Medusa JS Client](https://www.npmjs.com/package/@medusajs/medusa-js). You can install it with this command:
```bash npm2yarn
npm install @medusajs/medusa-js
```
There’s also an alternative approach in this document using [JavaScript’s Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch) in case you’re unable to use Medusa’s JS Client. Make sure to replace `<SERVER_URL>` in those examples with your server URL.
## Shipping Step
In this step, the customer generally enters their shipping info, then chooses the available shipping option based on the entered info.
### Add Shipping Address
After the customer enters their shipping address information, you must send a `POST` request to the [Update a Cart](https://docs.medusajs.com/api/store/#tag/Cart/operation/PostCartsCart) API endpoint passing it the new shipping address:

### List Shipping Options
After updating the cart with the customer’s address, the list of available [shipping options](../backend/shipping/overview.md#shipping-option) for that cart might change. So, you should retrieve the updated list of options by sending a `GET` request to the [Retrieve Shipping Options for Cart API](https://docs.medusajs.com/api/store/#tag/Shipping-Option/operation/GetShippingOptionsCartId) endpoint:

It is assumed you already have a Medusa server installed before following along with this tutorial. If not, you can get started in minutes by following the [quickstart guide](../quickstart/quick-start.md).

It's assumed that you already have a Medusa server installed and set up. If not, you can follow our [quickstart guide](../quickstart/quick-start.md) to get started.

It is recommended to use Medusa’s JS Client in your storefront. You can install it using the following command:
This guide includes code snippets to send requests to your Medusa server using Medusa’s JS Client and JavaScript’s Fetch API.
```bash npm2yarn
npm install @medusajs/medusa-js
```
:::note
This document alternatively shows code examples using [JavaScript’s Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch). Make sure to replace `<SERVER_URL>` in those examples with your server URL.
:::
Then, initialize the Medusa JS Client in a single file that all of your components can access:
```jsx
import Medusa from '@medusajs/medusa-js';
export const client = new Medusa({
baseUrl: '<SERVER_URL>',
maxRetries: 3
});
```
Where `<SERVER_URL>` is the URL of your server. If you’re using a local server, it runs on `http://localhost:9000` by default.
:::caution
Make sure to include `http://` in the URL when sending requests to the local server. Otherwise, all requests will fail.
