@moeed/nestjs-rate-limiter v1.0.0

Nest.js Rate Limiter Module

A simple and efficient rate limiting module for Nest.js applications. It leverages express-rate-limit to protect your application from abuse by limiting the number of requests that a client can make within a defined time window.

Installation

First, install the module using npm:

npm install @moeed/nestjs-rate-limiter --save

Make sure to also have express-rate-limit installed, as it is a peer dependency.

Usage

Import the RateLimiterModule into your root module and configure it using the register method:

import { RateLimitModule } from '@moeed/nestjs-rate-limiter';

@Module({
  imports: [
    RateLimiterModule.register({
      windowMs: 15 * 60 * 1000, // 15 minutes
      max: 100, // limit each IP to 100 requests per windowMs
    }),
    // ... other modules
  ],
})
export class AppModule {}

Custom Routes

You can specify custom routes to apply rate limiting by using the routes option:

RateLimiterModule.register({
  windowMs: 15 * 60 * 1000,
  max: 100,
  routes: [
    { path: '/api', method: RequestMethod.ALL },
    { path: '/auth/login', method: RequestMethod.POST },
  ],
})

Options

The following options can be used to configure the rate-limiting behavior:

• windowMs: The duration in milliseconds to keep track of requests (default: 60000).
• max: The maximum number of requests allowed within windowMs (default: 5).
• routes: An optional array of custom routes to apply rate limiting.

See the express-rate-limit documentation for more options and details.

Features

• Easy integration with existing Nest.js applications.
• Extends express-rate-limit, allowing for a wide range of customization.
• Global module availability.
