How to use Local Storage with JavaScript

Hi, My name is Andy Leverenz and I work as a Product Designer at Dribbble. For fun, I design, code, and write. Check out my blog called Web-Crunch https://web-crunch.com where I publish design and development tutorials with the occasional vlog.

It has been a bit since I did another Let’s Build: With JavaScript so I’m back with a new one focusing in on using Local Storage.

As a precursor to this tutorial I highly recommend not using local storage for comment data as I’m about to show you but rather more for small key-value assignments. For example, say you display a notification prompt, email subscription prompt, or alert of some kind on your site. You can hook into the browsers local storage API to save whether or not a given user wants to see these things as they display on your site.

That all could take place with a click event with JavaScript.

This tutorial goes one step further to show a proof of concept around adding a new comment to an existing comment feed. This in no way is complete but gives you an overview of how to both append new data to the DOM as well as store that data with local storage.

I invite you to extend this code to allow the commenter to delete their comments from local storage as well.
