Node.js global proxy setting - node.js

Question

I was working in a corporate network behind a proxy server. In my code I can set the proxy by using the approach mentioned in this thread.
But the problem is that most of the 3rd party modules do not have proxy setting and I cannot modify their code to add the proxy. Also, my code might be used in a direct connection environment which means I cannot hard-code my proxy setting in code.
I know NPM has a global setting for proxy which is
npm config set proxy http://proxy.company.com:8080
npm config set https-proxy http://proxy.company.com:8080
But I didn't find any config similar in Node.js.
Does Node.js support global proxy setting so that I don't need to change all codes and switch on and off easily?

Answer 1

Unfortunately, it seems that proxy information must be set on each call to http.request. Node does not include a mechanism for global proxy settings.
The global-tunnel-ng module on NPM appears to handle this, however:
var globalTunnel = require('global-tunnel-ng');
globalTunnel.initialize({
host: '10.0.0.10',
port: 8080,
proxyAuth: 'userId:password', // optional authentication
sockets: 50 // optional pool size for each http and https
});
After the global settings are establish with a call to initialize, both http.request and the request library will use the proxy information.
The module can also use the http_proxy environment variable:
process.env.http_proxy = 'http://proxy.example.com:3129';
globalTunnel.initialize();

I finally created a module to get this question (partially) resolved. Basically this module rewrites http.request function, added the proxy setting then fire.

You can try my package node-global-proxy which work with all node versions and most of http-client (axios, got, superagent, request etc.)
after install by
npm install node-global-proxy --save
a global proxy can start by
const proxy = require("node-global-proxy").default;
proxy.setConfig({
http: "http://localhost:1080",
https: "https://localhost:1080",
});
proxy.start();
/** Proxy working now! */

While not a Nodejs setting, I suggest you use proxychains which I find rather convenient. It is probably available in your package manager.
After setting the proxy in the config file (/etc/proxychains.conf for me), you can run proxychains npm start or proxychains4 npm start (i.e. proxychains [command_to_proxy_transparently]) and all your requests will be proxied automatically.
Config settings for me:
These are the minimal settings you will have to append
## Exclude all localhost connections (dbs and stuff)
localnet 0.0.0.0/0.0.0.0
## Set the proxy type, ip and port here
http 10.4.20.103 8080
(You can get the ip of the proxy by using nslookup [proxyurl])

replace {userid} and {password} with your id and password in your organization or login to your machine.
npm config set proxy http://{userid}:{password}#proxyip:8080/
npm config set https-proxy http://{userid}:{password}#proxyip:8080/
npm config set http-proxy http://{userid}:{password}#proxyip:8080/
