Api-Optimizer

api-optimizer is a lightweight and efficient Node.js package for optimizing APIs by providing middleware for rate limiting and caching with Redis. It helps in improving performance, preventing abuse, and managing load effectively.

Features

🚦 Rate Limiting: Prevent excessive API calls by limiting requests per IP in a specified time window. ⚡ Caching: Cache responses to reduce database load and improve response time. 💾 Redis Integration: Leverages Redis for distributed caching and rate limit storage. 🔧 Customizable: Configure rate limits, caching duration, and more.

Rate Limiting

Installation :

npm install api-optimizer

Imports & Use :

import {createRateLimit} from "api-optimizer";

const limiter = new createRateLimit({ windowMs: 60 * 1000, max: 5, message:"Too many requests"});

app.use(limiter);

Options :

| Options | Description | Default Value | |------------------|-----------------------------------|---------------| | windowMs | Time window in milliseconds | 60000 | | max | Maximum requests per time window | 5 | | message | Error message when rate-limited | "Too many requests, please try again later." |

Caching with redis

Installation:

npm install api-optimizer

Import & Use:

import {initializeRedis} from "api-optimizer";

initializeRedis({ url: 'redis://:', password: '', });

import {setCache,getCache,deleteCache} from "api-optimizer";

await setCache('key', { data: 'value' }, 3600); // Cache for 3600 seconds

const value = await getCache('key');

await deleteCache('key');
