#Redis-λ

Aim of this repo is to show how simple and swift it is to set up small APIs with AWS λ. Indeed λ service has HTTPS endpoints you can later on call with cUrl or fetch.

One must write short portions of code to store and retrieve datas. λ propose nodeJs or Python. (We chose nodeJs)

For the persistence nodeJs requires a redis client to communicate with a redis server one can find for free at redislabs

###This example is good way to set up "likes counter" in web apps

1 - To store a set with a value (Will return the number of hits for the pair)

curl -X POST -d '{"set":"days", "value":"tuesday"}' https://60zhqzqvuk.execute-api.us-west-2.amazonaws.com/prod/zincrby1

2 - To retrieve the set infos:

curl -X POST -d '{"set":"days"}' https://60zhqzqvuk.execute-api.us-west-2.amazonaws.com/prod/zrevrangebyscore
