I just put together a step-by-step tutorial for building serverless applications using React.js on AWS. It uses the Create React App and the React-Router. And I go through (in detail) how to set it up and deploy it on S3 and serve it out with CloudFront and Route 53. It started just as a reference for myself but I had a few friends that wanted to see it as well.
Would love for you guys to check it out and give me some feedback - http://serverless-stack.com
Let me know if there’s anything I’ve missed that I should be covering.
