Just run the run script; it should correctly initialize the environment at the first run (both cargo and npm)

./run

If this does not work, have a look at run and manually install the dependencies.

You will also need a .env file:

BASEMAP_KEY=XXX

You can retrieve the key from Mapbox.

Sometimes the hot-reload server or the thttp server just stay up, while building fails, etc. In case of "zombie" servers, try to fix it with --clean

./run --clean
