A set of packages for reuse within Heroku Go applications.
Development
The Makefile provides a few targets to help ensure the code is linted and tested.
$ make help
target help
------ ----
lint Runs golangci-lint. Override defaults with LINT_RUN_OPTS
test Runs go test. Override defaults with GOTEST_OPT
coverage Generates a coverage profile and opens a web browser with the results
ci-lint Runs the ci based lint job locally.
ci-test Runs the ci based test job locally
ci-coverage Runs the ci based coverage job locally
'ci-' targets require the CircleCI cli tool: https://circleci.com/docs/2.0/local-cli/
