RiotAPI

Node.JS minimal Riot API client written in Typescript

Features

• Rate limiting through @fightmegg/riot-rate-limiter
• Automatic retries
• TypeScript typings
• 100% endpoint coverage (incl. DDragon)
• Caching with custom ttls per endpoint
• Request prioritization

Installation

$ npm install @fightmegg/riot-api

Usage

import { RiotAPI, RiotAPITypes, PlatformId } from "@fightmegg/riot-api";

(async () => {
  const rAPI = new RiotAPI("RGAPI-KEY");

  const summoner = await rAPI.summoner.getBySummonerName({
    region: PlatformId.EUW1,
    summonerName: "Demos Kratos",
  });
})();

Config

const config: RiotAPITypes.Config = {
  debug: false,
  cache: {
    cacheType: "ioredis", // local or ioredis
    client: "redis://localhost:6379", // leave null if client is local
    ttls: {
      byMethod: {
        [RiotAPITypes.METHOD_KEY.SUMMONER.GET_BY_SUMMONER_NAME]: 5000, // ms
      },
    },
  },
};

const rAPI = new RiotAPI("RGAPI-TOKEN", config);

Error handling

If you use Promises then any error will reject the promise, this can either be an error value, or the response from the API.

Same as above with async/await, where the error thrown will be the response from the API if the error occured at that level.

Caching

Caching is turned off by default, but with the cache property in the config you can enable it with various settings. For now we only support local (in memory) or ioredis caches, will potential support for custom caches in future.

When setting up the cache, you can change the ttl of each method / endpoint individually. This is done through the METHOD_KEY type which can be found in the typings file.

DDragon

We also fully support DataDragon which can be accessed in two ways:

// ...
const rAPI = new RiotAPI("RGAPI-KEY");

const latestV = await rAPI.ddragon.versions.latest();
const champs = await rAPI.ddragon.champion.all();

If you want to just use static data only, then you can do the following:

import { DDragon } from "@fightmegg/riot-api";

const ddragon = new DDragon();
const champs = await ddragon.champion.all();

Just like the main API, we have full TypeScript typings for DDragon endpoints. Please note we do not support caching for DDragon endpoints.

regionToCluster

A helper method to make it easier to determing which cluster you want to hit based on the users region

import { regionToCluster } from "@fightmegg/riot-api";

const cluster = regionToCluster("EUW1"); // outputs "EUROPE"

TypeScript typing

import { RiotAPI, RiotAPITypes, PlatformId } from '@fightmegg/riot-api';

// ...

const summoner: RiotAPITypes.Summoner.SummonerDTO = await rAPI.summoner.getBySummonerName(...);

Debugging

If you want to see want the rate-limiter is currently doing, we use the debug module for logging. Simply run your app with:

DEBUG=riotapi* node ...

Testing

Unit tests: npm test

E2E tests: npm run test:e2e

Planned features

• Custom Caches
• Interceptors (before request & on response)
