Kindred

Kindred is a Node.js wrapper with built-in rate-limiting (enforced per region), caching (in-memory and Redis), and parameter checking on top of Riot's League of Legends API.

Core Features

• All standard endpoints covered but tournament endpoints.
• Supports both callbacks and promises.
• Rate limiter that is enforced per region and follows retry headers.
  • Retries on 429 and >= 500.
• Built-in parameter checks so you can hopefully refer to documentation less! :)
• Built-in caching (in-memory and Redis).
  • Customized expiration timers. You can set a timer for each endpoint type. Refer to Caching for more info.
• Designed to be simple but convenient. For example, you can call an exclusively by-id endpoint (such as grabbing the runes of a player) with just the name.

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 Quickstart Section to see what I mean.

Installation

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

Endpoints Covered

All examples here should be able to be run alone individually.

Make sure to check the official Riot Documentation to see what query parameters you can pass in to each endpoint (through the options parameter)!

Note: All region parameters are OPTIONAL. All options parameters are OPTIONAL unless stated otherwise.

Rate Limiter

So basically, I'm using psuedonym117's Python wrapper's rate limiter class and modified it a bunch to make it work. I'm simply doing a primitive rate-limiting-by-timestamps approach, nothing fancy.

You can test out the rate limiter (and see that it supports simultaneous requests to multiple regions) with the following code:

var num = 45 // # of requests

function count(err, data) {
  if (data) --num
  if (err) console.error(err)
  if (num == 0) console.timeEnd('api')
}

console.time('api')
for (var i = 0; i < 15; ++i) {
  k.Champion.all({ region: 'na' }, count)
  k.Champion.all({ region: 'kr' }, count)
  k.Champion.all({ region: 'euw' }, count)
}

This should output something like api: 20779.116ms.

To test that it works with retry headers, just run the program while sending a few requests from your browser to intentionally rate limit yourself.

Because of these lines, if (data) --num and if (num == 0) console.timeEnd('api'), you can tell if all your requests went through.

Caching

April 2 I have added caching support. Right now, the library supports in-memory caching as well as caching with Redis. These are the default timers that made sense to me.

const endpointCacheTimers = {
  // defaults
  CHAMPION: cacheTimers.MONTH,
  CHAMPION_MASTERY: cacheTimers.SIX_HOURS,
  CURRENT_GAME: cacheTimers.NONE,
  FEATURED_GAMES: cacheTimers.NONE,
  GAME: cacheTimers.HOUR,
  LEAGUE: cacheTimers.SIX_HOURS,
  STATIC: cacheTimers.MONTH,
  STATUS: cacheTimers.NONE,
  MATCH: cacheTimers.MONTH,
  MATCH_LIST: cacheTimers.ONE_HOUR,
  RUNES_MASTERIES: cacheTimers.WEEK,
  STATS: cacheTimers.HOUR,
  SUMMONER: cacheTimers.DAY
}

If you pass in cacheOptions, but not how long you want each type of request to be cached (cacheTTL object), then by default you'll use the above timers.

To pass in your own custom timers, initialize Kindred like this:

import TIME_CONSTANTS from KindredAPI.TIME_CONSTANTS // for convenience, has a bunch of set timers in seconds

var k = new KindredAPI.Kindred({
  key: RIOT_API_KEY,
  defaultRegion: REGIONS.NORTH_AMERICA,
  debug: true, // you can see if you're retrieving from cache with lack of requests showing
  limits: [ [10, 10], [500, 600] ],
  cacheOptions: CACHE_TYPES[0], // in-memory
  cacheTTL: {
    // All values in SECONDS.
    CHAMPION: whatever,
    CHAMPION_MASTERY: whatever,
    CURRENT_GAME: whatever,
    FEATURED_GAMES: whatever,
    GAME: whatever,
    LEAGUE: whatever,
    STATIC: TIME_CONSTANTS.MONTH,
    STATUS: whatever,
    MATCH: whatever,
    MATCH_LIST: whatever,
    RUNES_MASTERIES: whatever,
    STATS: whatever,
    SUMMONER: TIME_CONSTANTS.DAY
  }
})

Ugly

Some people might disagree with how I formed my functions.

It's actually not really idiomatic JavaScript, and with an object inside an object it gets ugly really fast.

The benefits of this approach is that it's implementing Python's named parameters in a way, which was my original goal with this project.

However, the problem is that some of the functions could be simplified a lot as they only have one parameter and no options such as grabbing a summoner by their summoner Id. You would want something like:

getSummonerById(id, region, cb)

I decided to make the first parameter always an object for my main library methods though because it made my functions very consistent with each other, and so I wouldn't have to look at the method documentation as much.

It was very easy to switch between functions and have the call still be successful with the same parameters.

However, it's easy to add functions.

You would simply have to define new functions within the class that return calls to my methods. I have a few examples within my code.

this.Ex = {
    getSummonerByAccId: this.getSummonerByAccId.bind(this),
    getMatchlistByName: this.getMatchlistByName.bind(this),
    getRunesBySummonerId: this.getRunesBySummonerId.bind(this),
    getRunesByAccountId: this.getRunesByAccountId.bind(this)
    staticRuneList: this.staticRuneList.bind(this)
}

getSummonerByAccId(accId, region, cb) {
    return this.Summoner.get({
        region,
        accId
    }, cb)
  }

getMatchlistByName(name, region, options, cb) {
    return this.Matchlist.get({
        region,
        name,
        options
    }, cb)
}

getRunesBySummonerId(id, region, cb) {
    return this.Runes.get({
        region,
        id
    }, cb)
}

getRunesByAccountId(accId, region, cb) {
    return this.Runes.get({
        region,
        accId
    }, cb)
}

staticRuneList(region, options, cb) {
    return this.Static.runes({
        region, options
    }, cb)
}

It could still be kinda funky, but now you can call the functions like this:

k.Ex
 .getMatchlistByName('Contractz')
 .then(data => console.log(data))
 .catch(err => console.error(err))

k.Ex
 .getRunesByAccountId(47776491)
 .then(data => console.log(data))
 .catch(err => console.error(err))

k.Ex
 .getSummonerByAccId(47776491)
 .then(data => console.log(data))
 .catch(err => console.error(err))

k.Ex.getRunesByAccountId(47776491, 'na', KindredAPI.print)
k.Ex.getRunesBySummonerId(32932398, 'na', KindredAPI.print)
k.Ex.staticRuneList('na', {}, KindredAPI.print)
k.Ex.staticRuneList('na').then(data => console.log(data))

k.Ex
 .getMatchlistByName('Contractz', 'na', {
    season: 3, queue: [41, 42]
 })
 .then(data => console.log(data))
 .catch(err => console.error(err))

k.Ex.staticRuneList('na', { runeListData: 'all' }, KindredAPI.print)

You can decide on how you want to namespace everything though.

Contributing and Issues

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!
