Streamlining File Uploads to Amazon S3 with GraphQL and Spring Boot and Testing with Postman.

In the era of modern web development, efficient file handling is a crucial aspect of building robust applications. Amazon S3 (Simple Storage Service) is a widely used cloud storage solution that provides scalable, secure, and durable object storage. In this article, we will explore how to upload a file to an S3 bucket using GraphQL, a query language for APIs, and then verify the process using Postman, a popular API testing tool.

Prerequisites:

• Basic understanding of GraphQL
• An AWS account with S3 bucket access
• Postman installed on your machine

Step 1: Set Up AWS S3 Bucket: Before diving into the GraphQL implementation, create an S3 bucket on the AWS console. Take note of the bucket name and ensure that you have the necessary credentials with write access.

Add the AWS access key, secret key, region, and S3 bucket name to the application.properties file as follows:

# AWS Credentials
cloud.aws.credentials.access-key=ABCDEFGHIJKLMNN
cloud.aws.credentials.secret-key=abcdefghijklmn
cloud.aws.region.static=ap-south-1

# S3 Bucket Name
application.bucket.name=my-bucket

# Additional AWS Cloud Stack Configuration
cloud.stack.auto=false
