hpagent
A ready to use http and https agent for working with proxies that keeps connections alive!
Install
npm install hpagent
Usage
Based on your infrastructure, you should use the http agent or the https agent. The following table will help you picking the right one.
Type | Proxy | Server |
---|---|---|
HttpProxyAgent |
HTTP | HTTP |
HttpProxyAgent |
HTTPS | HTTP |
HttpsProxyAgent |
HTTP | HTTPS |
HttpsProxyAgent |
HTTPS | HTTPS |
const { HttpProxyAgent, HttpsProxyAgent } = require('hpagent')
Once you have understood the right agent for your use case, you can instance it. It takes the same parameter of the Node.js core's http(s) agent and an additional proxy
option, which is the url of your proxy.
const http = require('http')
const { HttpProxyAgent } = require('hpagent')
const agent = new HttpProxyAgent({
keepAlive: true,
keepAliveMsecs: 1000,
maxSockets: 256,
maxFreeSockets: 256,
proxy: 'http://localhost:8080'
})
http.get('http://localhost:9200', { agent })
.on('response', console.log)
.end()
If your proxy requires basic authentication, you can configure it in the proxy url:
const http = require('http')
const { HttpProxyAgent } = require('hpagent')
const agent = new HttpProxyAgent({
keepAlive: true,
keepAliveMsecs: 1000,
maxSockets: 256,
maxFreeSockets: 256,
proxy: 'http://user:pwd@localhost:8080'
})
http.get('http://localhost:9200', { agent })
.on('response', console.log)
.end()
You can also pass custom options intended only for the proxy CONNECT request with the proxyConnectOptions
option,
such as headers or tls.connect()
options:
const fs = require('fs')
const http = require('http')
const { HttpProxyAgent } = require('hpagent')
const agent = new HttpProxyAgent({
keepAlive: true,
keepAliveMsecs: 1000,
maxSockets: 256,
maxFreeSockets: 256,
proxy: 'https://localhost:8080',
proxyConnectOptions: {
headers: {
'Proxy-Authorization': 'Basic YWxhZGRpbjpvcGVuc2VzYW1l',
},
ca: [ fs.readFileSync('custom-proxy-cert.pem') ]
}
})
http.get('http://localhost:9200', { agent })
.on('response', console.log)
.end()
