Infura Infra Test

Run me

1. Run go get
2. Enable ENV vars for API_BASE_URL, INFURA_PROJECT_ID, and PORT.
3. Run docker run --name infura-test-redis -p 6379:6379 --rm redis for launching a redis db instance.
4. Run the app go run main.go

Using the Docker image:

1. Run docker compose up

Libraries/Tools/Procedure

1. Used fiber web framework for building the Rest API, fiber is for Go what express is for node. WHy I used it?
   • It's Built on top of go fasthttp (an alternative to Go default net/http module) which is basically a better implementation to the way net/http launches a thread per request.
   • Fasthttp is built for handling thousands of rps, low or mid-size.
   • Fiber routing is pretty easy to set up, also has a lot of configs and middlewares available.
   • I've used it for a while.
2. Used a single endpoint InfuraHttpRequest. To handle a good amount of methods from the infura API.
   • First pass /:method in path. e.g. /eth_blockNumber or e.g. /eth_getTransactionByBlockNumberAndIndex.
   • If the method requires parameters, you can pass them (most of the time) with a query param ?params= with the list of params separated by comma. e.g., http://127.0.0.1:8000/eth_getTransactionByBlockNumberAndIndex?params=0x5BAD55,0x1
3. The Dockerfile is a pretty simple Multi stage Docker, compiling the Go code in container A, moving the generated executable to container B, running the container B.
4. Added 2 caching layers, the 1st made with redis, and the 2nd as a middleware from the fiber framework. (docker-compose.yaml with redis db added)
5. For the load tests, the project uses ddosify a pretty simple yet powerful cli testing tool. DETAILS ABOUT THE LOAD TESTS RESULTS HERE
