I am trying to make a portfolio-building app on aws. I am using reactjs for the front end, lambda(nodejs) for the backend, and other various technologies like dynamodb and API Gateway. My question is, how do I get the react content served up every time someone goes to my domain name? Is it done through lambda? Do I need an ec2 instance? I am stuck on this and if someone can help me out I would really appreciate it. Thanks!
There are many approaches you could use to set this up, it depends on what type or architecture you are looking for. I prefer to use AWS lambda functions attached to the API gateway for backend How To Build Your First Serverless API with AWS Lambda and API Gateway, and for frontend host the react.js app in s3 through cloudfront. This setup means that your entire application is serverless and you will be hard pressed to make it out of the free tier on AWS. Here is a great blog article detailing how to set this up Deploying create-react-app to S3 and CloudFront
