How to install

I also written the main class in ES6, however wanted the module to be compatible with npm so I can publish this to npm. I had issues with transpiling with import/export syntax from ES6 so reverted this back to ES5.

npm install ishouty_httprequest_andy

You can also download this from github

git clone https://github.com/ishouty/ishouty_httprequest.git

How to use (async/await) ES6 example

import ishouty_httpRequest from 'ishouty_httpRequest'

  const urls = [
      'https://ft-tech-test-example.s3-eu-west-1.amazonaws.com/ftse-fsi.json',
      'https://ft-tech-test-example.s3-eu-west-1.amazonaws.com/gbp-hkd.json',
      'https://ft-tech-test-example.s3-eu-west-1.amazonaws.com/gbp-usd.json',
    ]

  const callRequests = async (urlsParams) => {
    return await request.requestUrls(urlsParams)
  }

  callRequests(urls)

Tests

Tests are written in ES6 and transpiled via babel.

How to run tests

npm run test

How to watch tests

npm run test:watch

Improvements and features

• Pass configuration object to include default features for requests such as baseUrl
• Update more test coverage
