Check if a website is using Netlify by reading the HTTP server header field.

Installation

npm install --save @scanf/isun

Usage as module

const url = "https://jamstack.xdp.no/";

require("@scanf/isun").IsUsingNetlify(url, isun => {
  assert.equal(true, isun);
});

Usage as Lambda function on Netlify

Assuming you have deployed on Netlify and your domain is example.xyz, the below should work:

curl https://example.xyz/.netlify/functions/isun?url=https://google.com

The function expects you to set the query parameter url and be compliant with RFC 3986. Or simply put pass a valid url and remember to include https:// prefix :wink:
