Replace {version}
with the version of the package that you want to use, e.g.:
3.0.0
.
This library is provided in ESM as well as CJS forms, and works with both Javascript and Typescript projects.
This package requires you to use Node 16 or above.
Import it in a CommonJS project (type: commonjs
or no type
field in
package.json
) as follows:
const { RedisStore } = require('rate-limit-redis')
Import it in a ESM project (type: module
in package.json
) as follows:
import { RedisStore } from 'rate-limit-redis'
To use it with a node-redis
client:
import { rateLimit } from 'express-rate-limit'
import { RedisStore } from 'rate-limit-redis'
import { createClient } from 'redis'
// Create a `node-redis` client
const client = createClient({
// ... (see https://github.com/redis/node-redis/blob/master/docs/client-configuration.md)
})
// Then connect to the Redis server
await client.connect()
// Create and use the rate limiter
const limiter = rateLimit({
// Rate limiter configuration
windowMs: 15 * 60 * 1000, // 15 minutes
max: 100, // Limit each IP to 100 requests per `window` (here, per 15 minutes)
standardHeaders: true, // Return rate limit info in the `RateLimit-*` headers
legacyHeaders: false, // Disable the `X-RateLimit-*` headers
// Redis store configuration
store: new RedisStore({
sendCommand: (...args: string[]) => client.sendCommand(args),
}),
})
app.use(limiter)
To use it with a ioredis
client:
import { rateLimit } from 'express-rate-limit'
import { RedisStore } from 'rate-limit-redis'
import RedisClient from 'ioredis'
// Create a `ioredis` client
const client = new RedisClient()
// ... (see https://github.com/luin/ioredis#connect-to-redis)
// Create and use the rate limiter
const limiter = rateLimit({
// Rate limiter configuration
windowMs: 15 * 60 * 1000, // 15 minutes
max: 100, // Limit each IP to 100 requests per `window` (here, per 15 minutes)
standardHeaders: true, // Return rate limit info in the `RateLimit-*` headers
legacyHeaders: false, // Disable the `X-RateLimit-*` headers
// Redis store configuration
store: new RedisStore({
sendCommand: (command: string, ...args: string[]) =>
client.send_command(command, ...args),
}),
})
app.use(limiter)
The function used to send commands to Redis. The function signature is as follows:
;(...args: string[]) => Promise<number> | number
The raw command sending function varies from library to library; some are given below:
Library | Function |
---|---|
node-redis |
async (...args: string[]) => client.sendCommand(args) |
ioredis |
async (command: string, ...args: string[]) => client.send_command(command, ...args) |
handy-redis |
async (...args: string[]) => client.nodeRedis.sendCommand(args) |
tedis |
async (...args: string[]) => client.command(...args) |
redis-fast-driver |
async (...args: string[]) => client.rawCallAsync(args) |
yoredis |
async (...args: string[]) => (await client.callMany([args]))[0] |
noderis |
async (...args: string[]) => client.callRedis(...args) |
