Please export the RequestInit interface

[0x80]

I originally wrote this helper function for a project using node-fetch and I want to port it to unfetch, but I'm missing the RequestInit interface.

Without it I don't know how to type the options.

import fetch, { RequestInit } from "isomorphic-unfetch";
import { makeQueryString } from "../utils/query-string";

export async function fetchJson<T>(
 endpoint: string,
 queryParams: { [key: string]: string | number | boolean } = {},
 options: RequestInit = {}
): Promise<T> {
 const queryString = makeQueryString(queryParams);

 const url = `${endpoint}${queryString}`;

 const response = await fetch(url, {
 mode: "cors",
 ...options
 });

 if (!response.ok) {
 throw new Error(
 `Fetch to ${url} failed with status ${
 response.status
 }. Response text: ${await response.text()}`
 );
 }

 try {
 return response.json();
 } catch (err) {
 throw new Error(`Failed to parse JSON from response of ${url}`);
 }
}
