node-xmlhttprequest
A spec-compliant version of XMLHttpRequest that works in NodeJS.
Install
npm i --save node-xmlhttprequest
Quick Start
import { XMLHttpRequest } from 'node-xmlhttprequest'
const xhr = new XMLHttpRequest()
xhr.open('GET', 'https://example.com')
xhr.onreadystatechange = () => {
if (xhr.readyState === XMLHttpRequest.DONE) {
const html = xhr.responseText
const statusCode = xhr.status
const statusText = xhr.statusText
}
}
xhr.send()Synchronous XHR Calls
Synchronous XHR requests work too, without writing files as other packages do. Note that it does use worker threads.
Warning This option is only left in for compatibility reasons. It is not recommended for any reason as it will block the thread.
import { XMLHttpRequest } from 'node-xmlhttprequest'
const xhr = new XMLHttpRequest()
xhr.open('GET', 'https://example.com', false) // <-- note the false parameter
xhr.send()
assert(xhr.readyState === XMLHttpRequest.DONE)
const html = xhr.responseText
// ...Relative URLs
Note A relative URL is a URL that only contains a path.
Relative URLs do not behave the same as the browser. You must use undici to set a relative url, otherwise an error will be thrown.
import { XMLHttpRequest } from 'node-xmlhttprequest'
import { setGlobalOrigin } from 'undici'
setGlobalOrigin('https://example.com')
const xhr = new XMLHttpRequest()
xhr.open('GET', '/api/ping')
xhr.onreadystatechange = () => {
if (xhr.readyState === XMLHttpRequest.DONE) {
xhr.responseURL // https://example.com/api/ping
}
}
xhr.send()
