User-Agent overriden in Node

[terinjokes]

When using axios in NodeJS, a custom set User-Agent would be overriden by Axios's default, instead of being applied if a User-Agent isn't already set.

Hi friends! Anyway we could get this fix tagged in npm? We need this fix over at Vine, and I would rather not have to peg to a git commit in my package.json.

Thanks :)

+1, I could really use this fix in my project

+1 We could really use this fix but don't want to (read: can't) fetch directly from github.

I just released 0.6.0 which includes a fix for this.

@mzabriskie thanks so much!

@mzabriskie this might still be a problem when setting default headers in nodejs.

For my unit tests, I have the following config:

import axios from "axios"

const instance = axios.create()
instance.defaults.headers.common["User-Agent"] = "unit-test"
global.axios = instance

The intent is that I don't want to modify any of my code to conditionally set the user agent.

When I look at my development server, I see the following headers:

{ "accept": "application/json, text/plain, */*",
  "user-agent": "axios/0.16.2",
  "host": "localhost:3000",
  "connection": "close" }
