Question : How to force IPv4

[dparmar74]

Core "Http" module has a way to force IPv4 by specifying "family" option. See example below. How would I achieve this with "axios"?

var http = require('http');
var options = {
family: 4,
host: 'www.google.com',
path: '/index.html'
}

http.get(options, (res) => {
console.log(Got response: ${res.statusCode});
// consume response body
res.resume();
}).on('error', (e) => {
console.log(Got error: ${e.message});
});

axios does not support the family option directly, but you can use a custom agent to achieve this as follows:

var http = require('http');
var agent = new http.Agent({ family: 4 });
axios.get('http://www.google.com/', { httpAgent: agent }); // Note: use httpsAgent for HTTPS

You can also set the agent at the instance level:

var instance = axios.create({ httpAgent: agent });
instance.get('http://www.google.com/');

or at the global level:

axios.defaults.httpAgent = agent;

Hope this helps!

Mind that agent option has become httpAgent and httpsAgent in 0.14.0

@rubennorte Thank you! I've updated my comment.

Thank you for the suggestions. It worked with 0.12.0 (agent=agent) version but for 0.14.0 (httpAgent=agent) I'm getting ETIMEDOUT error. My test case involves making a http call to one of our micro service deployed on AWS EC2. Just wondering why it doesn't work with 0.14.0 version
