Instagram Helper (Scraper) Chrome Extension
I've just published a new version 0.23 of extension on Chrome Web Store. So when you click the extension icon, the displayed popup window has two buttons:
1) Get Insta Users (manual fetching). The previous approach of getting the list that requires the manual fetching, this option will be removed soon.
2) Get Insta Users. The new approach that creates a list for the username specified in the input control.
There are two options for autofetching
1) "Page size for fetching users" - amount of users to be returned in one click. The default value is 100, however debugging this functionality, I realised that instagram server doesn't respect this parameter too much, and usually returns about 20 users in one call.
2) "Interval between requests for fetching users, ms" - delay before issuing the next request when the processing of previous request is completed. If there is no delays, for fetching the long list of users, the instagram will start to return HTTP code 429 (too many requests, try several minutes later). Right now this situation is not handled, and the only option to avoid that is having a delay.
