This library was designed for gathering HAR files from requests sent using axios

Credits

Inspiration and some pieces of the code comes from maciejmaciejewski/request-har

Usage

In order to use this package install it

npm install axios-har-tracker

and import it by

import { AxiosHarTracker } from "axios-har-tracker";

and axios package

import axios from "axios";

which will be passed into AxiosHarTracker constructor:

const axiosTracker = new AxiosHarTracker(axios);

In order to perform an actual request use the axios.get/post/delete... call, examples:

await axios.get("http://httpstat.us/200");

or with catching an error

try {
  await axios.get("http://httpstat.us/404");
} catch (error) {
  console.log("An error appears after call to https://httpstat.us/404:", error);
}

Every single request is pushed into the object and user can get it by using

const generatedObject = axiosTracker.getGeneratedHar();

Object can be saved into a file in any time using e.g.

writeFileSync("example.har", JSON.stringify(generatedObject), "utf-8");

axios-har-tracker's Issues

Only captures some request headers

@BeataKr Thank you for publishing this library - it has been a huge help!

I noticed that it only captures the common request headers:

axios-har-tracker/src/axios-har-tracker.ts

Line 91 in a2015d1

headers: this.getHeaders(config.headers['common']),

Please could you tell me if this is a deliberate design choice or just an oversight? I would be very interested in either having an option to capture all request headers, or that being the default behavior. I thought I’d best check first what the rationale for the current design was.

Does this lib catches only GET requests?

I've tried to implement the lib, however I was not able to generate any pages. It does output an empty json file:
{"log":{"version":"1.2","creator":{"name":"axios-har-tracker","version":"0.1.0"},"pages":[],"entries":[]}}

I've done everything by the instructions and I'm passing the axios object at the begging, however it fails to capture anything.
