How to enable HTTPS on Webpack Dev Server

crysfel Programming

One of the most popular feature requests of the Music App is to support memberships using Stripe. A few days ago I decided to work on this new feature, however, I found a few challenges along the way. First of all, if we want to use Stripe we need to run our application over HTTPS, otherwise the JavaScript SDK doesn't run properly. In production that's quite easy to accomplish, in fact, the demo version, as well as the community I run using this software, are both running over HTTPS. But when Continue reading

Improving readability In order to improve code readability and therefore lowering the maintenance cost for this service, I was introducing async/await to Continue reading

A few days ago I had to implement a sticky banner at work, at first I thought it would be a simple task but it took me quite some time to figure everything out. On the bright side, I've learned a few new things about CSS in the process. Here are the requirements: The component might be present sometimes depending on some custom logic on the backend. When present, it had to push all the content down and when closed by the user, it had to disappear with a slide up animation. Effectively animating Continue reading
