How to listen to changes in an external website?

[regal rock]

I am trying to do the following:

• Scrape rows (announcements) from a third party website
• Store the scraped announcements into my PostgreSQL database
• Have a GET route to fetch all announcements.

I want the scraping part to be automated; maybe with something like a goroutine?
Is there a way to constantly listen to any changes?
If my only option is a goroutine, how would I go about implementing it?

Unless the website has webhook support or something your only option is to scrape it every x minutes and compare with the last time you scraped

You can use time.Ticker for that
