HTTP

The HTTP service allows you to create HTTP calls and receive Javascript promises to manage your call response results.

All of Litespeed.js internal HTTP calls used by the framework are managed by the HTTP service.

Currently the HTTP service uses the XMLHttpRequest API to handle all HTTP calls but in future releases we do intend to start using the newer Fetch API.

API

• get(url)
• post(url, headers, payload)
• put(url, headers, payload)
• patch(url, headers, payload)
• delete(url)
• addGlobalParam(key, value)
• addGlobalHeader(key, value)
