Is URL Online?

A lightweight library for checking if a url is down or not. Pretty useful while checking if the url inserted is correct one or fake one as normal url checking methods won't work.

Supports both Server and browser due to ohmyfetch

Getting started

pnpm install is-url-online

or

npm install is-url-online

or

yarn add is-url-online

Improvements over other libraries

• Promise based usage.

• Works on both CommonJs and EsModule based libraries.

• Smaller install size because of just one dependency.

• Built using typescript.

• Catches invalid URLs.

• Actively maintained.

• Automated Dependency update and publishing after successful tests.

• Has helper methods to deal with extra usecases.

Usage

import { isUrlOnline } from "is-url-online";

await isUrlOnline("https://github.com/spa5k/is-url-online"); //-> true

await isUrlOnline("https://github.com/spa5k/notarepo"); //-> false

await isUrlOnline("notaurl"); //-> false

await isUrlOnline("ttps://github.com/spa5k/is-url-online abcd"); //-> false
//because of a space in middle.

Utils

Only Check URL String

This helper method will validate the URL string without checking it online.

import { isUrlString } from "is-url-online";

await isUrlString("https://google.com"); //-> true

await isUrlString("https://google.com/404ingURL"); //-> true

await isUrlString("notaurl"); //-> false

It uses URL module under the hood.

Prepend HTTP/HTTPS

This helper method prepend https:// or http:// to humanized URLs like github.com and localhost

import { prependHttp } from "is-url-online";

// HTTPS is enabled by default.

prependHttp({ url: "github.com" }); //-> https://github.com

prependHttp({ url: "github.com", https: false }); //-> http://github.com
