dog.ceo golang lambda functions

The AWS Lambda functions used for the dog.ceo api.

Old version in node.

make deps
make clean

Setup process

Dependencies

go get ./...

Compiling

make

NOTE: If you're not building the function on a Linux machine, you will need to specify the GOOS and GOARCH environment variables, this allows Golang to build your function for another system architecture and ensure compatibility.

brew install aws-sam-cli
brew install awscli
make build && make start

brew install aws-sam-cli
brew install awscli
make deploy
