Proxy to Socksv5

[c0debreaker]

Is it possible?

TBH. Never tried it.

You could try these npm packages: https://www.npmjs.com/package/socks5-https-client https://www.npmjs.com/package/socks5-http-client

And configure the proxy agent similar to: https://github.com/chimurai/http-proxy-middleware/blob/master/recipes/corporate-proxy.md

Basically provide a socksv5 compatible agent as config.

Let me know if this works or not.

Cool. I'll let you know. Thanks!

Hi chimurai. We enabled http proxy and it's working now. :)

I have a question though. Since this configuration is proxy-agent or as client, what does the target property really do especially the agent is already pointing to a proxy server?

var options = {
    target: 'http://localhost:3000',
    agent: new HttpsProxyAgent('http://internal-squid-svr:3128')
};

var apiProxy = proxy('/api', options);

Glad to hear you've found a working setup. Mind sharing which npm module you used for HttpsProxyAgent?

You can see target as application logic. i.e. proxy /api request to this target.

How the actual requests/connection are handled is determined by agent https://nodejs.org/dist/latest-v9.x/docs/api/http.html#http_class_http_agent These requests can be configured to go through another proxy as well...

The npm proxy module is the one from the link you sent above, http-proxy-agent. :)

Another question. When my request is https, I don't see the traffic goes to our proxy. What could be wrong in my setup? I'm using the same configuration from https://github.com/chimurai/http-proxy-middleware/blob/master/recipes/corporate-proxy.md

Here is my setup. On my laptop, I'm running http-proxy-middle-ware and http-proxy-agent. Let's say our http proxy is 192.168.1.1:2301

var proxyConfig = proxy({
  agent: new HttpsProxyAgent('http://192.168.1.1:2301'),
  target: 'http://website-A.example.com'
});
app.use('/', proxyConfig);

However, I also need to reach https://website-B.example.com and this is the one that I cannot reach. However, if I configure my browser's network proxy setting pointing to http://192.168.1.1:2301, I can reach https://website-B.example.com. What could be missing on my code?

can target: be an array like this. Is this possible?

var proxyConfig = proxy({
  agent: new HttpsProxyAgent('http://192.168.1.1:2301'),
  target: ['http://website-A.example.com', 'http://website-B.example.com']
});
app.use('/', proxyConfig);

I got it working :)

I created two entries

app.use('/app/path', proxyHttpConfig);
app.use('/app/another/path', proxyHttpsConfig); // <- this is working now :)
app.use('/', proxyHttpConfig);
