AWS has come out with some pretty rad stuff recently. Lambda has my functional microservice pants in a twist. I have bult tons of nodejs services in the past but with Lambda I can forget about the wholle HTTP/s bitand just write some code. So, after using serverless to deploy my functions and set up the api gateway, I needed to put all this AWS goodness behind my own URL. Unfortunately, API Gateway requires a certificate and it can't be one create in ACM. So using certbot I ran the following:

certbot certonly --config-dir `pwd` --logs-dir `pwd` --work-dir `pwd` -a manual --rsa-key-size 2048 -d api.kyletilman.com

(for some reason certbot only looks in /etc for config and stuff)

Certbot is put together by EFF and letsencrypt.org.

The initial function seemed straightforward and very close to functional programming but there was a bit of buried complexity.

function generate(seedWords) {
  const filteredWords = filterInputs(seedWords);
  const initialHash = R.head(filteredWords) || 'thunder';
  const hashWithRandom = appendRandom(initialHash);
  return generateHelper(hashWithRandom, R.tail(filteredWords));
}

	// Before
	// Ad-hoc polymorphism (changing internal function logic based on datatype)
	// Does extra work on an empty string
	// repeats the toLowerCase().indexOf() portion internally
	// Doesn't have tests
	// Dangles a return in an unecessary else statement
	function searchContains (query, value) {
	var stringifiedNumber;
	if (typeof value === 'string') {
	return value.toLowerCase().indexOf(query) > -1;
