An example NodeJS API (GraphQL) with lambda handler backed by DynamoDB using the DataMapper lib. Includes CloudFormation template for resources and GitHub Workflows for CI/CD.
This is a contrived example, intended to demonstrate things you'd normally only incorporate into a larger bespoke app, such as:
- Configuration supporting multiple environments and environment variable based config
- Dependency Injection (DI) supporting app and request scoped containers
- Logging
- GraphQL using ApolloServer with both standalone and lambda entry points
- Testing using mocha and chai, using Test Explorer for local dev
- Unit tests
- Integration tests
- Approval tests
- Launch configurations:
- Step through debug the app via ts-node (without compiling JS first)
- Run utility tasks in debug mode
- Build / Deploy:
- Building, both for a lambda target (using webpack) and as a standalone NodeJS server application (not using webpack)
- Deployment to CloudFormation with YAML based templates
- Github CI/CD workflows
I agree with doing things the simplest way. Ideally you'd just use AWS AppSync or Amplify frameworks instead of what I have put together here. However, if you have reasons why you defer to bespoke coding, I'd personally prefer to stick to patterns I've successfully used before.
