Summoners Tail

This project tracks a Summoner via the Riot Games API. Given a summoner, it will then track the other summoners from their last five matches, watching their activity for an hour.

Usage

At this time, this project is expected to run from IEx. It requires an API key from Riot Games. You can register and attain a key at https://developer.riotgames.com/

Development API keys are good for 24 hours, but are subject to rate limiting.

You can pass the token by setting the environment variable in your shell

export RG_API=RGAPI-abcdef12-3456-####-####-####-############

Recent Summoners

To invoke from IEx,

summoner_name = "Allie"
region = "NA1"

participants = SummonersTail.recent_summoners(summoner_name, region)

Limitations

Validation

The code isn't doing much defensive validation at this time. For example, if a function expects an ID, it assumes it is being passed a valid ID returned by a previous API call. Only the summoner name is escaped, partly because the API supports spaces in names and so this needed to be covered.

Abstraction

There is some repetitive code. I generally follow a "rule of three", where after the third piece of similar code I abstract it out to a common function. There's room for that here, but I haven't tackled it yet.

Lifecycle

At this time, if the Monitor crashes, there is no recovery. This is aligned with the expectation that everything is running from IEx at the moment.
