软件介绍
dnscache for Node 封装了 Node.js 的 dns 模块方法,在这之间提供缓存层。每个到 dns 方法的调用看起来都是本地缓存。dnscache 非常类似 GOF Proxy 设计模式,提供一个缓存代理。
dnscache 主要目标是缓存大部分 dns 调用,避免网络延迟,提升性能。
安装
npm install dnscache
使用
var dns = require('dns'),
dnscache = require('dnscache')({
"enable" : true,
"ttl" : 300,
"cachesize" : 1000
});
//to use the cached dns either of dnscache or dns can be called.
//all the methods of dns are wrapped, this one just shows lookup on an example
//will call the wrapped dns
dnscache.lookup('www.yahoo.com', function(err, result) {
//do something with result
});
//will call the wrapped dns
dns.lookup('www.google.com', function(err, result) {
//do something with result
});配置
