Adding headers after axios instance is created

[crofoot]

As the title says I was wondering if there is a way to add headers after an instance is created? So for example before the user authenticates I don't have an authorization header. But once they login I want to inject the authorization header into the current instance. Any help would be greatly appreciated!

There are a few ways to do this. By default axios-hooks uses the default axios instance, which you can import anywhere else in code with import axios from 'axios'. In that case you can provide global defaults or even use an interceptor.

Another way would be to use a custom axios instance and configure axios hooks to use it, then use again the axios instance defaults or interceptors to add your header.

Thanks that worked! I had to add the header to the specific axios instance I created.
