Template-based importer (vs. using L.DomUtil)

[davidbgk]

After a discussion with @almet we realized that it would be possible to write HTML in templates instead of building everything on the JS side using L.DomUtil, this is a first small step to verify that it's both possible and pertinent.

There are still some rough edges but let's discuss the direction in itself first!

Templates are tempting, but I feel like until we need all those querySelector the final benefit is small, while it also adds a small indirection / complexity (declaring HTML in some file, and using it in another).
Also, given Leaflet itself is programmatic, this means introducing another pattern alongside.
I liked your experiment much as a direction, even if of course the step would be much bigger.
At this stage, the direction is not totally clear to me.

We might want to go a step further and turn that form into a web component in itself which is able to do its stuff (select build from data, checks, auto-selected fields on upload) on itself prior to dispatch a custom event with the result to uMap's core JS.

I'd love to give it a try 😇

Sounds appealing! But what would be the browser support ?

Custom elements are not fully baseline compliant :'( But it's coming!
