javascript - Implementing shopping cart using localStorage

Question

I'm in the process of writing a simple shop for my business, and I'm currently implementing the cart logic. I use vanilla JS in the client side and communicate with the server via JSON API, I render everything in the client side.

From my research online, I discovered that some online shops maintain the user cart in their database, so to add/remove/modify an item, you need to send an HTTP request to the server. I don't want to do that, because of the overhead and my idea is to maintain the cart in localStorage and on checkout, send the whole cart at once.

Is this a good idea? What issues can occur when managing a shopping cart in the client side? I am asking that because I assume there is a reason many online shops manage the user cart in their database (apart from collecting data on users)

Thanks.
