    Bonus geometry types in GeoJSON

Basically two types:

Rectangles
Circles

Let's say you have a drawing tool that permits both. Both geometry types benefit from some non-standard drawing abilities: it would be nice to resize circles, and it would be nice to resize rectangles in a way that keeps them rectangular. However, GeoJSON does not have circle or rectangle types. Both are represented as polygons. This gives us two options:

"Detect" these shapes with a heuristic. This is doable for a rectangle by checking the corners, but much, much less doable for circles. Also, circles have an additional property that I will mention in the next bit.

    My least favorite part of the web platform

Behold, the worst part of the web platform: user gestures.
In short, let's say you've built a web application that edits maps, or… does something else, hypothetically. You implement file saving in that application using the fancy new native browser APIs. Then you have to do some stuff to process or load the file when you click Save - like if you're converting the file and you want to do it in a WebWorker for optimum smoothness. Soon, you will meet this error message:

SecurityError Failed to execute 'showSaveFilePicker' on 'Window': Must be handling a user gesture to show a file picker.

This is just one example of "user gesture" restrictions: you can also find them when you request permissions or attempt to open windows. Basically, to crack down on bad actors or misuse, the browser restricts certain functions to only being called in connection with a click handler.

                MapBox OpenLayers Example
              
          
    An example of integrating MapBox with OpenLayers.
To use this example, you'll want to:

Replace layer_id with one of your layers from MapBox - click 'Publish' and copy the ID.

To do more with OpenLayers, see the API documentation and examples for this release. Read MapBox's REST API Documentation for more services that can be used.

                Stripe webhooks in development
              
          
    Micro-devlog for something tiny.
Placemark uses Stripe, and uses their webhooks. You can use Stripe without webhooks, but it's better to build with the webhooks.
I'm developing the account system actively, so I want the webhooks to work in local development. Thankfully, the stripe cli supports proxying webhooks from your development Stripe environment to your local setup. You run
$ stripe listen --forward-to localhost:5000/stripe_webhooks
