All endpoints covered but one (get summoner by accountIDs).
Basic rate-limiting that is enforced per region.
- Retries on 429 and >= 500 (should it just be 500?).
Tells you what parameters you can pass in when you make a parameter-related error.

Hopefully there aren't too many bugs! I'm a noob after all, so use this library at your own risk. I'm currently working on adding caching and fully support promises (it might be a bit buggy atm).

Philosophy

My goal is to make a wrapper that is simple, sensible, and consistent. This project is heavily inspired by psuedonym117's Python wrapper. Look at the Usage Section to see what I mean.

This is my first try at making an API wrapper. I am open to any advice and help!

March 28, 2017

I'm pretty proud of the end result. The rate limiting isn't the best, but it does work and is enforced per region! Also, the method names are kinda iffy (minor inconsistencies), but it works really well for my other project and for when I need a quick script. I'll try to improve this library over the next few weeks.

Installation

yarn add kindred-api
// or npm install kindred-api

Contributing and Issues

Feel free to make a PR regarding anything (even the smallest typo or inconsistency).

There are a few inconsistencies and weird things within this libary that I don't know how to address since this is my first API wrapper and I'm still quite a big newbie.

For example, the two methods getChamp() and getChampion() are actually different.

getChamp() targets the champ endpoint

getChampion() targets the static endpoint

I didn't want to attach getChampion() with 'static' in any way or form since I thought it looked kind of annoying because then I would want to attach static to the other static methods as well (maybe that's better?).

Right now, the code is also quite messy and there is a lot of repeated code. Function definitions are quite long because I include many aliases as well. I haven't thought of an elegant way to make a magic function that manages to work for every single endpoint request yet.

Any help and/or advice is appreciated!
