@highpoint/js-fetch

js-fetch

This is a small library to make using JavaScript's fetch a bit easier. It provides some utility functions to handle common request types.

The library assumes that responses will be in JSON format. If a response is not going to be in that format, then you can still use the library, but most of its usefulness will be gone.

Also included are some HighPoint-specific requirements like CSRF support and postMessages to parent informing it that the user is actively using child.
