getDefaultRequestConfig

getDefaultRequestConfig returns the default configuration object we use when making requests with fetch(). It sets a POST method along with sensible Accept and Content-Type headers.

It's used internally by fetchJSON, but you can also call it directly and spread/merge your own overrides on top when building a bespoke request.

The optional type argument (default 'json') controls the Accept header — e.g. passing 'javascript' produces Accept: application/javascript.

info

Currently the default method provided by getDefaultRequestConfig is POST, so GET must be specified for GET requests

Usage examples​

Basic​

window.BAO.utils.getDefaultRequestConfig()
// {
//   method: 'POST',
//   headers: {
//     Accept: 'application/json',
//     'Content-Type': 'application/json',
//   },
// }

Merging in your own options​

const config = {
  ...window.BAO.utils.getDefaultRequestConfig(),
  method: 'GET'
}

fetch('/cart.js', config)
