How to set localAddress when sending HTTP requests?

[wesfc]

Describe the issue

I need to set my local address to be used on my request.
Is there some way to do it?

PS: I already check axios requests documentation and I know the option localAddress is not listed there.

Example Code

const options = {};
options.localAddress = <my-local-address>

return axios.post(url, location, options)
    .then((result) => {})
...

Expected behavior

I would expect to be able set my local address on HTTP requests.

You can do it by utilizing the underlying HTTP agent in Node.js:

const agent = new http.Agent({ localAddress: '192.168.1.100' }); // Replace with your desired local address

const options = {};
options.httpAgent = agent;

return axios.post(url, location, options)
    .then((result) => {})

What I typically do is create a configurable Axios client using a factory function. Here is an example, where the fallback is a local address. Setting the environment variable HTTP_REQUEST_ADDRESS can alter where HTTP requests are made.

import axios from "axios";

function clientFactory() {
  return axios.create({
    baseURL: process.env.get("HTTP_REQUEST_ADDRESS", "http://127.0.0.1:8080"),
    timeout: 3 * 1000,
  });
}
