## Prerequisites
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).
### 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 Medusas storefronts. If you dont 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.
## Install the JS Client
### JS Client
It is recommended to use Medusas 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 Medusas JS Client and JavaScripts Fetch API.
```bash npm2yarn
npm install @medusajs/medusa-js
```
:::note
This document alternatively shows code examples using [JavaScripts 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 youre 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.
:::
If you follow the JS Client code blocks, its assumed you already have [Medusas JS Client installed](../js-client/overview.md) and have [created an instance of the client](../js-client/overview.md#configuration).
