For many applications, one desirable feature is the user’s ability to upload a profile image. However, building this feature can be a challenge for developers new to GraphQL, which has no built-in support for file uploads.

In this tutorial, you will learn to upload images to a third-party storage service directly from your backend application. You will build a GraphQL API that uses an S3-compatible AWS GO SDK from a Go backend application to upload images to DigitalOcean Spaces , which is a highly scalable object storage service. The Go back-end application will expose a GraphQL API and store user data in a PostgreSQL database provided by DigitalOcean’s Managed Databases service.

By the end of this tutorial, you will have built a GraphQL API using Golang that can receive a media file from a multipart HTTP request and upload the file to a bucket within DigitalOcean Spaces .
