The most lightweight scraper for individual website pages

There is a certain website that constantly updates its data. Unfortunately, there is no API available to access this information programmatically in JavaScript, which presents a common challenge for me.

To tackle this issue, I have created a simple JavaScript script embedded in HTML called hackyAPI. This client-side solution allows me to manipulate the data as needed.

The main hurdle I am facing now is with XMLHttpRequest and cross-server permissions. I prefer not to add server elements just for this purpose. Is there a workaround that would allow me to get a standard HTML response without introducing additional server components?

Answer №1

Browsers have implemented CORS restrictions to specifically block such scripts (including more harmful XSS scripts); the owner of that website is responsible for providing and serving those resources, so unless they have a public API available, it would be unfair to access their data in the manner you are attempting. This action appears to violate the site's terms of service in this instance.
