Basic rate-limiting middleware for Express. Use to limit repeated requests to public APIs and/or endpoints such as password reset. Plays nice with express-slow-down and ratelimit-header-parser.

The full documentation is available on-line.

import { rateLimit } from 'express-rate-limit'

const limiter = rateLimit({
	windowMs: 15 * 60 * 1000, // 15 minutes
	limit: 100, // Limit each IP to 100 requests per `window` (here, per 15 minutes).
	standardHeaders: 'draft-7', // draft-6: `RateLimit-*` headers; draft-7: combined `RateLimit` header
	legacyHeaders: false, // Disable the `X-RateLimit-*` headers.
	// store: ... , // Use an external store for consistency across multiple server instances.
})

// Apply the rate limiting middleware to all requests.
app.use(limiter)
