Synchronously check if a URL exists.

URL Exists Sync

Synchronously check if a URL exists.

Use asynchronously

If you are able to run this in an asynchronous context, I highly recommended that you do so with url-exist since synchronous web requests can hang/freeze clients.

Install

npm install url-exist-sync

Usage

import urlExistSync from "url-exist-sync"

urlExistSync("https://google.com")
//=> true

urlExistSync("https://google.com/404ingURL")
//=> false

urlExistSync("notaurl")
//=> false

API

urlExistSync(url)

url

Type: string

The URL to check.

Returns false for accessible urls when run in VPN environment

I am running the command behind VPN. Node js has the required proxy settings for http and https but still even Google url fails:

const urlExistSync = require("url-exist-sync");
undefined
urlExistSync("https://google.com");
false

What could be the issue here ?
