@windyroad/fetch-fragment

A library that provides a function to fetch a JSON fragment from a response based on a URL fragment identifier.

Installation

npm install @windyroad/fetch-fragment

Usage

import { fetchFragment } from '@windyroad/fetch-fragment';

const response = await fetchFragment('https://example.com/data.json#/foo/bar');
if (response.ok) {
  const data = await response.json();
  // Use the data...
} else {
  console.error(`Failed to fetch fragment: ${response.status} ${response.statusText}`);
}

The fetchFragment function takes a URL with a fragment identifier, fetches the URL, and returns a new response with only the JSON fragment specified by the fragment identifier. If the response is not JSON the function returns a 415 response. If the the fragment is not found the function returns a 404 response.

The fetchFragment function is implemented using the addFragmentSupportToFetch function, which can be used to add fragment support to any fetch implementation. Here is an example:

import { addFragmentSupportToFetch } from '@windyroad/fetch-fragment';

const fetchWithFragmentSupport = addFragmentSupportToFetch(fetch);

const response = await fetchWithFragmentSupport('https://example.com/data.json#/foo/bar');
if (response.ok) {
  const data = await response.json();
  // Use the data...
} else {
  console.error(`Failed to fetch fragment: ${response.status} ${response.statusText}`);
}
