Local File Storage

This document will guide you through installing the local file storage plugin on your Medusa backend.

Overview

To upload and manage file assets in Medusa, you need a file service plugin responsible for hosting the files. Without a file service plugin, you will face issues while working with Medusa, such as when uploading images for products.

Medusa provides three different options to handle your file storage. The local file storage plugin makes it easy to upload file assets locally during development.

For production, it's recommended to use a file service plugin that hosts your images on a third-party service. This file service doesn't handle advanced features such as private uploads, which means you can't use it for functionalities like import or export products. Check the file service plugins for available other options to use.

Prerequisites

A Medusa backend is required to be set up before following along with this document. You can follow the quickstart guide to get started in minutes.

Plugin Installation

In the directory of your Medusa backend, run the following command to install the local file service plugin:

npm
Yarn
pnpm

npm install @medusajs/file-local

yarn add @medusajs/file-local

pnpm add @medusajs/file-local

Then, configure your medusa-config.js to include the plugin with the required options:

medusa-config.js

const plugins = [
  // ...
  {
    resolve: `@medusajs/file-local`,
    options: {
      // optional
    },
  },
]

If you have multiple storage plugins configured, the last plugin declared in the medusa-config.js file will be used.

Options

You can pass the plugin the following options:

upload_dir: a string indicating the relative path to upload the files to. By default, it's uploads/images.
backend_url: a string indicating the URL of your backend. This is helpful if you deploy your backend or change the port used. By default, it's http://localhost:9000.

Test it Out

Run your Medusa backend alongside the Medusa Admin to try out your new file service. Upon editing or creating products, you can now upload thumbnails and images, that are stored locally in your backend.

The files will be stored under the upload_dir specified in the plugin options (if no option is specified, they'll be stored in the uploads/images directory by default.)

Next.js Starter Template Configuration

If you’re using a Next.js Starter Template, you need to add an additional configuration that adds the backend's domain name into the configured images domain names. This is because all URLs of product images will be from the Medusa backend.

If this configuration is not added, you’ll receive the error "next/image Un-configured Host”.

In next.config.js add the following option in the exported object:

next.config.js

const { withStoreConfig } = require("./store-config")

// ...

module.exports = withStoreConfig({
  // ...
  images: {
    domains: [
      // ...
      "<BACKEND_URL>",
    ],
  },
})

Where <BACKEND_URL> is the URL of your backend. If you're running the backend locally, the value would be localhost.
