Web scraping related question [JS]

[Shmoopy]

Hi there,

I would like to know how do web scraping I/O services manage to scrape websites without getting blocked by the CORS.

Because I've tried scraping with a tool I've made with Javascript, but my Iframe keeps getting blocked by the browser because of the Cross-origin request. ( Tested with all the main browsers )

 

However, when I've exported my project with NWJS, there was no CORS. But I don't want to build a desktop software, instead I wanna make a Web app like all the services out there.

 

So my question is, how do web scrapping services manage to bypass CORS ?

 

Thanks.

 

Found the secret:
