📚 Description

This fix needed to provide custom $fetch() options, like a providing custom parseResponse() function to fix the memory leak caused by destr() function:

import type { FetchOptions } from 'ohmyfetch';

/**
 * Parse response
 * @description Replace of `destr()` function to prevent memory leak
 * @param responseText
 */
const parseResponse: FetchOptions['parseResponse'] = (responseText) => {
  // Send empty string if zero length
  if (responseText.length === 0) {
    return '';
  }

  try {
    return JSON.parse(responseText);
  } catch (_e) {
    return responseText;
  }
};

// Example of usage
useFetch('/', {
  parseResponse,
};
