add basic web UI

[paigewilliams]

I branched off of #1142 to address the PR feedback from @nyurik .

Let me know if there is a better way to submit these changes for review.

[nyurik]

thx! I will be able to review it fully next week (I'm at FOSS4G conference). One thing -- is it possible to make martin-ui/src/_assets/logo.png into a symlink? I don't think we should duplicate files in the repo unless we have to.

[nyurik]

P.S. please merge in the latest main branch

[nyurik]

a few minor changes, plus I merged and pushed the latest main branch. One thing -- for some reason, CI fails for this PR - need to fix that

Looking at all the requests when viewing localhost:3000/ while setting RUST_LOG=debug, I see these requests:

So it clearly gets BOTH /assets and /_assets -- not good. Moreover, it IS possible to create an _assets source, so it could conflict. The only way to NOT have any conflicts is to add all assets to /_/assets/* path -- this way it will never conflict (the _ is a reserved keyword)

I'm not sure that this PR is complete. When I run npm run build && npm run dev in the martin-ui sub-directory, the UI runs fine. When I run cargo run -- ./world_cities.mbtiles, local is unable to find the js file at the root, but is able to find a css file at /assets. I'm not sure what is happening at cargo run ... that would prevent it from finding the js file.

[nyurik]

why would anything access things at /assets/...?

[paigewilliams]

I think that my latest change meets what you are looking for with js, css and image files all served from _/assets. Running cargo run -- ./world_cities.mbtiles now runs the web UI at /.

If it doesn't, can you outline the directory or output build structure you have in mind?

[nyurik]

thanks!! Lets do some basic UI in a next PR - before we do a release

@nyurik Agreed, do you have a list of basic features in mind? I would imagine a map, and maybe a list of checkboxes for the sources available at /catalog that the user can toggle on/off to show in the map?

[nyurik]

@paigewilliams lets discuss it in #1120 -- there are some ideas there already
