What is the proper way to input a Response object retrieved from a fetch request?

I am currently handling parallel requests for multiple fetches and I would like to define results as an array of response objects instead of just a general array of type any. However, I am uncertain about how to accomplish this. I attempted to research "how to type response object in Typescript" but unfortunately did not find any helpful results. Is there a way to specify the response object type without manually creating a custom type that encompasses all properties of a response object? Does Typescript offer a specific built-in type that can be utilized in this scenario?

const results: any = [];

fetch(URL, {
  headers: {
    ...
  }
})
  .then(response => {
    results.push(response);
  })
  .catch(err => {
    ...
  })
  
const responses = await Promise.all(results);
return responses;

Answer №1

For my project, I utilized the node-fetch library and came up with this solution. Check it out here!

import { Response } from 'node-fetch';

const results: Response[] = [];

fetch(URL, {
  headers: {
    ...
  }
})
  .then(response => {
    results.push(response);
  })
  .catch(err => {
    ...
  })
  
const responses = await Promise.all(results);
return responses;
