Notes

Got this error in my stack trace when initially setting up the repo

Container map-postgres Healthy
map           | psql: error: could not translate host name "map-postgres" to address: Name or service not known
map           | Waiting 5 seconds for PostgreSQL to come up: postgres@map-postgres/map...

I believe it was resolved after I changed the port mapping

[derekeder]

imported these from https://colorbrewer2.org/. may be worth keeping in

[derekeder]

this could be a function we stub out but ask them to implement

[derekeder]

these default styles can be kept in

positron base map

[derekeder]

site would not successfully come up before changing this

Looking good!
