🤖RoboNews🤖

RoboNews is a serverless email newsletter that delivers weekly news about AI and LLMs, written by an LLM!

Technical details

• Uses a LOT of AWS services
  • Cloudformation, Lambda, S3, DynamoDB, EventBridge, KMS, ECS, Route 53, Cloudfront
• Serverless design
  • Subscription page uses S3, Cloudfront, Certificate Manager, and Route 53 to create a serverless website with HTTPS
• One-Click Deployment
  • The project includes a deployment script which uses the AWS CLI to push source code to ECS and S3, and then deploys the Cloudformation template
  • If I were to do it again I'd probably use CDK instead of the CLI
  • A future addition that I decided was out of scope for now is a CI/CD pipeline that automatically deploys changes when they're pushed to origin
• Signed URLs
  • Confirm-Email & Unsubscribe buttons use signed URLs so users can only manage their own account
  • URLs are encrypted/decrypted with KMS
• Containerized Lambda
  • Newsletter is sent by a lambda function in an ECS container
    • If I were to do it again I would use S3 and lambda layers tbh
  • Lambda is triggered by an EventBridge cron job
  • Source code uses a "plugin" architecture making it easy to add news sources and output types
  • Gets headlines from RSS feeds, and then summarizes them with Langchain-OpenAI
