Leaderboards

Use a sorted set when Redis should rank members by score.

import { zset, string } from "benni/schema";

export const leaderboards = zset("leaderboard", string());

Record scores:

await redis.zset(leaderboards).zadd("weekly", [
  { member: "user:42", score: 1200 },
  { member: "user:7", score: 950 }
]);

Increment a score:

await redis.zset(leaderboards).zincrby("weekly", 25, "user:42");

Read the top 10:

const top = await redis
  .zset(leaderboards)
  .zrange("weekly", { start: 0, stop: 9, rev: true });

Read scores with members:

const ranked = await redis
  .zset(leaderboards)
  .zrange("weekly", { start: 0, stop: 9, withScores: true });

Raw Redis equivalent:

await nodeRedis.zIncrBy("leaderboard:weekly", 25, "user:42");
const top = await nodeRedis.zRange("leaderboard:weekly", 0, 9, {
  REV: true
});
