Typescript gives, “Could not find a declaration file for module 'xmlhttprequest'.”

Question

Using,

import { XMLHttpRequest } from \'xmlhttprequest\';

On Node I get the following error when I compile with tsc

Answer 1

Can you try to do npm install @types/xmlhttprequest --save in your command line.

If it gives you error, then it means that xmlhttprequest library does not support TypeScript.

Answer 2

That means that the library does not contain type definitions and nobody from the DefinitelyTyped project wrote them. So you can't have the compiler do any typechecking. You can still use the library either

import * as xhr from 'xmlhttprequest'

Or, depending on version of your compiler

const xhr = require('xmlhttprequest')
