Cloudflare Adds Security.txt Setup Wizard
Cloudflare has launched a setup wizard allowing users to easily create and manage a security.txt file for vulnerability disclosure on their websites.
@keyv/redis
Advanced tools
@keyv/redis is an npm package that provides a Redis storage adapter for Keyv, a simple key-value storage library. It allows you to use Redis as a backend for storing key-value pairs, making it easy to integrate Redis into your Node.js applications.
Basic Key-Value Storage
This feature allows you to store and retrieve basic key-value pairs using Redis as the backend. The code sample demonstrates how to set and get a value from the Redis store.
const Keyv = require('keyv');
const keyv = new Keyv('redis://user:pass@localhost:6379');
(async () => {
await keyv.set('foo', 'bar');
const value = await keyv.get('foo');
console.log(value); // 'bar'
})();
Expiration of Keys
This feature allows you to set an expiration time for keys. The code sample demonstrates how to set a key with an expiration time and shows that the key is no longer available after the specified time.
const Keyv = require('keyv');
const keyv = new Keyv('redis://user:pass@localhost:6379');
(async () => {
await keyv.set('foo', 'bar', 1000); // Expires in 1 second
setTimeout(async () => {
const value = await keyv.get('foo');
console.log(value); // undefined
}, 1500);
})();
Namespace Support
This feature allows you to use namespaces to avoid key collisions. The code sample demonstrates how to set and get a value within a specific namespace.
const Keyv = require('keyv');
const keyv = new Keyv({ uri: 'redis://user:pass@localhost:6379', namespace: 'myapp' });
(async () => {
await keyv.set('foo', 'bar');
const value = await keyv.get('foo');
console.log(value); // 'bar'
})();
ioredis is a robust, full-featured Redis client for Node.js. It supports advanced Redis features like clustering, sentinel, and pipelining. Compared to @keyv/redis, ioredis offers more direct control over Redis commands and is suitable for more complex use cases.
redis is the official Node.js client for Redis. It provides a straightforward API for interacting with Redis and supports all Redis commands. While @keyv/redis focuses on key-value storage with a simple API, redis offers more granular control and flexibility.
node-cache is an in-memory caching module for Node.js. It provides a simple API for storing key-value pairs with optional expiration times. Unlike @keyv/redis, node-cache does not use Redis as a backend and is suitable for use cases where in-memory storage is sufficient.
Redis storage adapter for Keyv
Redis storage adapter for Keyv.
TTL functionality is handled directly by Redis so no timestamps are stored and expired keys are cleaned up internally.
npm install --save keyv @keyv/redis
const Keyv = require('keyv');
const keyv = new Keyv('redis://user:pass@localhost:6379');
keyv.on('error', handleConnectionError);
Any valid Redis
options will be passed directly through.
e.g:
const keyv = new Keyv('redis://user:pass@localhost:6379', { disable_resubscribing: true });
Or you can manually create a storage adapter instance and pass it to Keyv:
const KeyvRedis = require('@keyv/redis');
const Keyv = require('keyv');
const keyvRedis = new KeyvRedis('redis://user:pass@localhost:6379');
const keyv = new Keyv({ store: keyvRedis });
Or reuse a previous Redis instance:
const KeyvRedis = require('@keyv/redis');
const Redis = require('ioredis');
const Keyv = require('keyv');
const redis = new Redis('redis://user:pass@localhost:6379');
const keyvRedis = new KeyvRedis(redis);
const keyv = new Keyv({ store: keyvRedis });
Or reuse a previous Redis cluster:
const KeyvRedis = require('@keyv/redis');
const Redis = require('ioredis');
const Keyv = require('keyv');
const redis = new Redis.Cluster('redis://user:pass@localhost:6379');
const keyvRedis = new KeyvRedis(redis);
const keyv = new Keyv({ store: keyvRedis });
