I am interested in som how I can track changes on any website e.g. e-shop and track change on the element. For example, I want to get notification when price will be changed.
I think, that it can be done via Cron trigger (every hour) => http request to the website => parse html => compare the value with the old one.
I found, that there is a function called Introduction | Docs for storage small data and I want to ask you, if there is no better way for this type of use.
If you want to store larger amounts of data the static-data is really not a good option. It is then better to simply store in some kind of external datastore like Postgres, Redis, MySql, Airtable, Google Sheets, … or even a simple local file. For all the mentioned possibilities nodes exist already and should so not be too complicated to set it up.
Just gave your workflow a whirl and so far so good. However, I’d like to track all prices change - not just lower prices - but I can’t seem to figure things out. I hoped it would be enough to change the condition in IF2 to “not equal to” but then I get a notification every time the flow runs with the current price as the new price and nothing for the previous price.
