proxy-from-env 1.1.0

Proxy-from-env is a Node.js package that provides a function known as getProxyForUrl. This function accepts a URL as input and returns the respective proxy URL, following the Environment Variables such as *_PROXY (example, HTTP_PROXY) and NO_PROXY. In instances where no proxy is defined, the function will return an empty string. It should be noted that 'proxy-from-env' identifies the proxy, but the actual task of proxying the request is handled by the incorporating program.

To use proxy-from-env, first install it via npm usnig the command npm install proxy-from-env. The function getProxyForUrl is then imported from the proxy-from-env package. This function can be used to identify the proxy for a specific URL. Here's an example:

var getProxyForUrl = require('proxy-from-env').getProxyForUrl;
var some_url = 'http://example.com/something';

var proxy_url = getProxyForUrl(some_url);  // Obtain the proxy URL

if (proxy_url) {
  // Process the request via the proxy_url
  // The rest of the processing code goes here
}

In this code snippet, getProxyForUrl is used to determine the proxy for the some_url. If a proxy is defined, then the relevant processing can be done via this proxy.
