Any URL you can open in Safari on iOS you can make an icon for on the homescreen. I used this feature recently to make one-click access to a QR code I needed to get my hands on very quickly.

One thing that’s been keeping us very busy at CodePen is moving our main API. We decided on GraphQL long ago and it’s served us pretty well. We originally built it in Ruby on Rails alongside a lot of the rest of our app. But while Rails served us well, we’ve been moving off of […]

Of course you can use Preact on CodePen! Here’s a two minute video that’ll show you exactly how: Main points from the video: You can copy and paste code you find around the web in docs, blog post, and REPL’s into CodePen, but the ESM import statements likely need to point to cloud-hosted and built […]

Robert and I jump on to chat about Cloudflare’s product Durable Objects. It’s part of their Workers platform, which we already use at CodePen a good bit, but with Durable Objects… Global Uniqueness guarantees that there will be a single instance of a Durable Object class with a given ID running at once, across the […]

In this show, Stephen and Chris get to talk about an internal technical detail we were improving in our database, which led to a public-facing feature for y’all. The idea is that all (most, anyway) database tables should have a deleted_at column. When you query against them, under regular circumstances, any rows that have a […]

They are easy to browse, easy to copy URLs or code snippets of usage, served with the right headers from a fast global CDN, and heck, we’ll even help optimize them. It’s easy to amass a lof of them, as we […]
