Portfolio Backend

This is the repository for any server based calls for my Portfolio Site

It is using AWS CDK to define a stack with the relevant resources

AWS Resources

  • Send Email Lambda
    • This will send emails from the contact form using AWS SES
  • Captcha Verify Lambda
    • This validates the captcha on a request with HCaptcha and acts as an authorizer function on the API Gateway
  • Lambda Layer
    • This contains common Node dependencies accross the lambda's, currently containing:
      • Dotenv
      • Aws-sdk
      • Aws-xray-sdk
  • Api Gateway
    • Endpoints for the app to call to process requests
  • IAM Roles
    • For resources to call relevant services i.e. AWS SES
