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

1const { 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.

1const http = require('http')
2const { HttpProxyAgent } = require('hpagent')
3
4const agent = new HttpProxyAgent({
5  keepAlive: true,
6  keepAliveMsecs: 1000,
7  maxSockets: 256,
8  maxFreeSockets: 256,
9  proxy: 'http://localhost:8080'
10})
11
12http.get('http://localhost:9200', { agent })
13    .on('response', console.log)
14    .end()

If your proxy requires basic authentication, you can configure it in the proxy url:

1const http = require('http')
2const { HttpProxyAgent } = require('hpagent')
3
4const agent = new HttpProxyAgent({
5  keepAlive: true,
6  keepAliveMsecs: 1000,
7  maxSockets: 256,
8  maxFreeSockets: 256,
9  proxy: 'http://user:pwd@localhost:8080'
10})
11
12http.get('http://localhost:9200', { agent })
13    .on('response', console.log)
14    .end()
