Can't use rate-limit-redis

[mathysth]

I'm trying to use rate-limit-redis but it's not working and compiling because of the redisStore .
Has the readme said I could use this store but I can't because of this error:

Type 'RedisStore' is not assignable to type 'Store'.

Here my setup

import { IocContainer, LoggerService, type ConfigService } from "@cosmoosjs/core";
import type { Server } from "@cosmoosjs/hono-openapi";
import { rateLimiter } from "hono-rate-limiter";
import RedisStore from "rate-limit-redis";
import { createClient } from "redis";

export async function setupRateLimit(server: Server, config: ConfigService) {
  try {
    const redisClient = createClient({
      url: config.get<string>('REDIS_URL')
    });

    await redisClient.connect();
    const limiter = rateLimiter({
      windowMs: 10 * 60 * 1000, // 10 minutes
      limit: 100,
      standardHeaders: "draft-6", // draft-6: `RateLimit-*` headers;
      keyGenerator: (c) => {
        console.log(c);
        return "<unique_key>";
      },
      store: new RedisStore({
        sendCommand: (...args: string[]) => redisClient.sendCommand(args),
      }),
    });

    // Apply the rate limiting middleware to all requests.
    server.hono.use(limiter);
  } catch (error) {
    const logger = IocContainer.container.get(LoggerService);
    logger.pino.error('An error occurred while connecting to redis');
    logger.pino.error(error);
  }
}

Hey, can you please provide me a reproduction of this, like on CodeSandbox or Stackblitz?

Hey it will take sometime so I will give you instead the file url, i'm also using bun.sh here

I tried creating a sample app, using pnpm. It did work out of the box (the rate-limiting stuff), but there is a type error. The error message is

Type 'ConfigType<any, any, {}>' is missing the following properties from type 'Options': legacyHeaders, validate

hono-rate-limiter doesn't support legacyHeaders and validate properties, as these are something that express-rate-limit itself suggests to void use for newer applications. So to avoid the type errors, we can do this

const limiter = rateLimiter({
  windowMs: 60 * 1000, // 1 minute
  limit: 5,
  standardHeaders: "draft-6", // draft-6: `RateLimit-*` headers;
  keyGenerator: (c) => {
    return "<unique_key>";
  },
  store: new RedisStore({
    sendCommand: (...args: string[]) => redisClient.sendCommand(args),
  }) as unknown as Store // Adding the correct type
});

It's working for me thanks for the help
