Introduction

This module is a promise-based scraper of Steam sales using the infinite scrolling web API endpoint. I didn't get rate limited while trying to scrape every deal. It took a minute, but the promise finally resolved into the correct array. The imported module is a single function which accepts one parameter and returns a promise. The parameter is optional and can be used to set the maximum amount of deals returned by the function. If it's left as undefined, the scraper will return every deal. Of course, the smaller number you set the quicker you'll get your result. The only dependency of this module has is axios. No HTML parsing, just pure text manipulation.

This is my second package, please don't judge me. Happy scraping everyone!

N/A and other values that don't make sense

Steam lists some games that cannot be bought separately, only in a bundle. These consequently don't have a price tag either. They are included because if the bundle is on sale the game itself gets listed (even if you can't buy the game itself). Keep them or remove them, these are included in the maximum amount you set and I've decided to return them for clarity's sake.
