Best Friends Forever (BFFs): Lambda and Go Apps
summary
Demo app GoForTweets posts Tweets on users' behalf using personal OAuth tokens (tokens not stored) via a Go backend deployed as AWS Lambda + API Gateway and a React frontend hosted on S3 behind CloudFront. Local development uses SAM (sam local start-api) to reproduce cold starts; CI runs sam build/deploy from CircleCI and performs blue‑green rollouts with CodeDeploy. Changes deploy successfully and displayed live tweets in the demo.
