funktion

Simple microservice built using GCP Cloud Function

Development environment

It's development environment runs on top of Docker and to get it up and running you must build it

docker-compose build

Then you can run the server

docker-compose run --rm funktion

If you need to access bash, npm, etc. you can just lunch a container as follows

docker-compose run --rm funktion [bash|npm|etc.]

Consuming

Consider using some tool like httpie

http localhost:5000/funktion
http localhost:5000/funktion/user
http localhost:5000/funktion/user/1
http POST localhost:5000/funktion/user/1 name="John Doe"

I've used Apache Benchmark.
