Prerequisite

The AssetServerPlugin is part of a standard Vendure installation, but if it is not already installed, you must install it:

npm install @vendure/asset-server-plugin

Install AWS SDKs

Before using this strategy, make sure you have the @aws-sdk/client-s3 and @aws-sdk/lib-storage packages installed:

npm install @aws-sdk/client-s3 @aws-sdk/lib-storage

Configure the AssetServerPlugin for MinIO

// vendure-config.ts
import { AssetServerPlugin, configureS3AssetStorage } from '@vendure/asset-server-plugin';
import { DefaultAssetNamingStrategy } from '@vendure/core';

// ...

plugins: [
  AssetServerPlugin.init({
    route: 'assets',
    assetUploadDir: path.join(__dirname, 'assets'),
    namingStrategy: new DefaultAssetNamingStrategy(),
    storageStrategyFactory: configureS3AssetStorage({
      bucket: 'my-minio-bucket',
      credentials: {
        accessKeyId: process.env.MINIO_ACCESS_KEY_ID,
        secretAccessKey: process.env.MINIO_SECRET_ACCESS_KEY,
      },
      nativeS3Configuration: {
        endpoint: process.env.MINIO_ENDPOINT ?? 'http://localhost:9000',
        forcePathStyle: true,
        signatureVersion: 'v4',
        // The `region` is required by the AWS SDK even when using MinIO,
        // so we just use a dummy value here.
        region: 'eu-west-1',
      },
    }),
}),
