@har-sdk/capture

Fetch requests in HAR format

This module makes a request and captures it as a HAR object. Under the covers it uses request and just passes through all options. Currently only GET requests are supported although other methods will probably work. The request body might not be properly captured though.

It can now be also used in stream mode. This means that it will stream data events containing the body of the response and then at the end event, the HAR object will be accessible.

Setup

npm i --save @har-sdk/capture

API

import { captureHar } from '@har-sdk/capture';

captureHar(
  {
    url: 'http://www.google.com'
  },
  { withContent: false }
).then((har) => {
  console.log(JSON.stringify(har, null, 2));
});

requestOptions

The options for making the request, is just passed through to request package. This can accept the url directly.

harOptions

Optional configuration for the resulting HAR object.

withContent

Defaults to true. Specifies whether the response content object should contain the full body of the response.

maxContentLength

Defaults to Infinity. Limits the response body to a maximum byte size. If the response body is larger than the specified limit, the content text won't exist and an error will be returned for this entity with the code MAX_RES_BODY_SIZE.
