A drop-in replacements for fetch, Request, and Response with first class support for JSON objects.

Unlike other HTTP libraries, this one stays as close as possible to the original Fetch API, while improving the ergonomics the most common use case:

Before:

const response = await fetch('/some', { 
  method: 'POST',
  body: JSON.stringify(json), 
  headers: {
    'Content-Type': 'application/json',
  },
});

After:

import { JSONRequest } from '@worker-tools/json-fetch';

const response = await fetch(new JSONRequest('/some', { 
  method: 'POST', 
  body: json,
}));

You can also use the updated jsonFetch function:

import { jsonFetch as fetch } from '@worker-tools/json-fetch';

const response = await fetch('/some', { method: 'POST', body: data })

Note that previous use cases remain intact, i.e. posting FormData, ReadableStream, etc. as body works:

const response = await fetch(new JSONRequest('/some', { 
  method: 'POST', 
  body: new FromData(form),
}))

This will send the body as form-data/multipart with correct content type header, as in the original Fetch API. Only difference is that the Accept header will be set to indicate preference for application/json, i.e. anticipating a JSON response from the server.
