We’ve had realtime features on CodePen for ages. Back when it was pretty damn hard. Our Collab Mode is an obvious one, where users can code together. (This “just works” in the 2.0 editor, it’s not called anything special.) That and Professor Mode used to have realtime chat (until we pulled it because very few […]

Rachel and Chris on the show this week to discuss a series of big changes over the last, say, six months or so with our billing system. We’ve essentially re-written this thing several times, and obviously this is the best time. Having three plans, two payment providers, teams, and fifteen years of history is a […]

Having that first response from the server to users browsers be, ya know, full of good, useful, renderable HTML is certainly better than an empty <div id=”app”>. You can feel it and see it in the filmstrip view of the site loading. Not to mention you need it for at least things like <meta> tags […]

Stephen and Chris chat about how the 2.0 editor (well, the compiler really) understands and supports Browserslist, a config format that lives in your package.json file that multiple blocks can understand and make browser support decisions against. Sponsor: Notion With the recent launch of Custom Agents, Notion became the collaborative AI workspace where teams and […]

As we’re getting close to rounding out the Beta period of the 2.0 editor, we’re trying to close out any bugs we find or users report quickly. They could be browser-support related, network conditions related, account capability related, or just bugs in how the 2.0 editor and technology behind it works. It’s complicated enough that […]

The 2.0 Editor can support hundreds of files per Pen, not to mention folders mixed in which don’t count toward that total. This can be pretty weighty on the DOM and thus adversely affect performance. Especially as each file/folder has children, a variety of event listeners, are drag and drop enabled, etc. “Virtualizing” data like […]

Stephen and Chris hop on the ol’ podcast to talk about all the ways that Templates are way better in 2.0 land. You’ve always been able to make your own templates, but now you can select one even after you’ve arrived in the editor. There is a new place (the create page) which features bookmarked […]

Alex and Chris talk about how the 2.0 Editor supports packages from npm. The trick is both simple and complex. The idea is simple. We detect the packages you want to use, list them in an (editable) package.json file, then turn that into a <script type=”importmap”> in your HTML files that import those packages from […]

Stephen & Chris look at the UI of the 2.0 Editor and show all the control you have over what you’re looking at. Way more control than the Classic editor! We share some of the thinking behind it. Don’t miss the Omnibar! Time Jumps Links

With CodePen 2.0, we’ve got a new word we’re using: Blocks. A way to think about Blocks is anything that processes code. They are added as steps to the CodePen Compiler as needed. For example, TypeScript is a block, because it processes files in the TypeScript syntax into JavaScript files. But something like Lodash is […]
