Etherium parser

What does this code do?

An implementation of a simple etherium blockchain parser allowing users to subscribe to addresses and query subscriptions for transactions.

How to use?

1. You can run the code using the vanilla Go binary with go run cmd/blockchain_parser/main.go and then use a tool such as Postman to hit the api
2. There is also a VSCode Launch Configuration which will allow debugging/breakpoints etc if required. See VSCode debugging
3. You can run the provided integration tests locally by using the Makefile command make test which will build and run the binary on localhost:8080 and run the integration sh script. Upon completion the process is killed
4. You can run the Unit Test suite via make test-unit

Further work

Due to time constraints the code is pretty basic. Further work could develop the following things:

1. API documentation using tools such as Swagger/OpenAPI
2. Address validation using regex
3. CI scripts for further automated testing such as linting or quality gateways / vulnerability testing using Sonarqube or similar
4. Container support by adding Dockerfile or Kubernetes manifests as required
5. More refined build steps which introspect platform architecture to build appropriate Go binaries
6. Increased reliability through a genuine persistance layer using tools such as Redis or a database
