Prerequisites

• Node.js >= 16.0.0
• TypeScript >= 4.9.0
• Medusa >= 1.12.0

Installation

1. Install the Module

npm install @medusajs/brand-module

2. Register the Module

In your medusa-config.js:

const modules = {
  // ... other modules
  brand: {
    resolve: "@medusajs/brand-module",
    options: {
      image: {
        thumbnailSize: 100,
        listSize: 200,
        gallerySize: 600,
        productSize: 400,
        defaultFormat: "webp",
        defaultQuality: 80
      }
    }
  }
}

3. Run Migrations

medusa migrations run

Image Storage

By default, the module stores image URLs and their processed variants. The actual images should be hosted on your preferred storage solution (e.g., S3, CloudFront). The module processes images and generates the following variants:

• Thumbnail (100px width)
• List view (200px width)
• Gallery view (600px width)
• Product view (400px width)
• Original (preserved with optimization)

All variants are generated in WebP format for optimal performance.

Logging

Custom logger implementation for better debugging:

• Prefixed log messages
• Different log levels (info, warn, error)
