I'm currently building a simple CRUD client-side only data logger PWA that contains no client-side JavaScript apart from what is inside the service worker. To do that I am following basic REST principles, and just using the Form element to submit data to the service-worker that then stores in it IndexedDB and renders the results back out to the client. I will explain more in another post, but in this post I want to quickly document how I fixed an issue in Safari.
By default Hugo doesn't serve .mjs files with the correct content type. In fact it wasn't until recently that hugo could serve more than one file extension per mime-type. It looks like with v0.43 this has been fixed.
[mediaTypes] [mediaTypes."text/javascript"] suffixes = ["js", "mjs"]

The above code lets me serve mjs files for ES Modules with the correct mime-type (note modules need to be served with 'text/javascript'). This is only needed for local testing, hosting is another issue :)
I've got thoughts on the post I did yesterday about ES Modules
I needed a quick way import a simple module get-urls into my project. The module is well tested and it does what I needed … ignore the fact that it’s pretty easy to implement in a couple of lines of JavaScript. The problem I had is that my project is built in ES6, uses modules and I didn’t want to have to bundle up using CommonJS (require).
I've been working on a way to make it easier to push content into my static site and it's been a fun little exercise that I will share more in another post. In this post I want to share the rollup config that I used to import nearly any npm module in to a frontend project using JavaScript modules.

Last year just before the Chrome Dev Summit, Miguel Casas came up to me and showed me something that blew my mind: Face Detection in the browser using the Shape Detection API. Shortly after that Barcode Detection was added that allowed me to update my QR Code scanner so that I no longer had to include a massive (albeit awesome) port of a QR scanning library.
The Shape Detection API is still in development, and neither the FaceDetection nor the Barcode Detection API's are available outside experimentations (you need to enable "Experimental Web Platform features" in chrome://flags) but it is a very exciting space to watch and see another platform capability being opened up to developers and users on the web.
Within the last 6 months, it felt like a good time to get on board properly with Web Components so I've been toying around with bits and pieces. I've been thinking about the ecosystem as a whole and I've also recently been creating a few elements.
One thing that is really unclear to me is that there is no defined best practice for how to include styles and templates (HTML) with your custom element which means as a consumer of Custom elements you are at the mercy of what the component developer thinks is best.
In a recent project building a web push service I wanted to have my UI respond to application level events (semantically if you will) because there were a couple of components that require information from the system but are not dependent with each other and I wanted them to be able to manage themselves independently of the 'business logic'.
I looked around at lots of different tools to help me, but because I frequently have a heavy case of NIH syndrome and the fact that I think people can implement their own infrastructural elements pretty quickly, I decided to quickly knock-up a simple client-side PubSub service — it worked pretty well for my needs.
The other week I talked about Face Detection via the Shape API that is in the Canary channel in Chrome. Now barcode detection is in Chrome Canary too (Miguel is my hero ;)
Barcodes are huge! they are on nearly every product we buy. Even the much maligned QRCode is huge outside of the US and Europe. The barcode and the QRcode provide a simple way for you to bridge the physical world and the digital world by transferring small amounts of data between the medium and you.
