ip-rate-limiter v1.0.1

ip-rate-limiter

An expressJS ip-rate-limit middleware built with TypeScript which inspired by Dcard's internship program.

Requirements

• 限制每小時來自同一個 IP 的請求數量不得超過 1000
• 在 response headers 中加入剩餘的請求數量 (X-RateLimit-Remaining) 以及 rate limit 歸零的時間 (X-RateLimit-Reset)
• 如果超過限制的話就回傳 429 (Too Many Requests)
• 使用 TypeScript + express + redis 完成

Quick Start

Install

$ npm install ip-rate-limiter

Basic Usage

	import express, { Application, Request, Response, NextFunction } from 'express';
	import rateLimiter from 'ip-rate-limiter';
	import bodyParser from 'body-parser';

	const app: Application = express();

	app.use(bodyParser.json());

	app.get('/', rateLimiter, (req: Request, res: Response) => {
		res.send('test');
	})

	app.listen(5000, () => {
		console.log('server running on port 5000');
	})

Roadmap

• Flexible arguments
• Increase Unit Test Coverage
• Support for other Redis Client
