How to start writing a code that parses a website data made with react js?

Question

I need to crawl a react js website which can help me fetch data from website.

Answer 1

If the react contents are generated from javascript, we cannot crawl them from server by server script, we could use headless browser with Puppeteer library to write srcript for loading javascript contents onto headless browser first before can be scraped.

Answer 2

I did not understand your answer as I'm a novice. But, will try to figure out something.
