Recently I recognized that some SaaS (Software as a Service) products use AWS Amplify which helps them to build serverless full-stack applications. I think serverless computing will be the future of apps and software. Therefore, I wanted to gather some hands-on experience, and I built a serverless application using AWS Amplify that uses React as frontend framework and GraphQL as backend API.
