# Serverless GraphQL @ Edge + Global DynamoDB Tables

Why? Mostly for fun. I don't see too many practical use cases for such setup. Lambda@Edges aren't suitable for a lot of cases due to limited memory and CPU, so they are *slow*. If you need a globally available website with dynamic content, you should consider going with JAMStack served via CloudFront, Vercel or Cloudflare.

## Features

- Globally and highly available

- GraphQL Server at each of Edge locations using Lambda@Edge + CloudFront

- Globally replicated DynamoDB Tables

- GraphQL handlers routing to the closest DynamoDB table as persistence layer

- Pay-what-you-use model, no upfront or fixed charges, everything billed per-request

- Infra managed using AWS-CDK and Typescript

- Node functions packaged and minified automatically using Parcel, ([there's a small bug though](https://github.com/aws/aws-cdk/issues/8031))

## Useful commands

 * `npm run build`   compile typescript to js

 * `npm run deploy`  deploy this stack to your default AWS account/region

## Limitations

- Your server must be rather lightweight. Minified GraphQL Server code must be less than `1 MB`. Lambda@Edge is restricted to `128MB` of memory and `5000ms` of timeout for `VIEWER_REQUEST` integration type.

- Cannot use ENV variables

- Table name is hardcoded, gonna fix that

- Schema creation is laborious right now
