I guess, I needed to do an
npm update
for it to work ?

[ralfhauser]

what do I have to do to trigger fromDataBlue.js execution ?
~/git/proximap $ ls -lart src/assets/
...
-rwxrwx---+ 1 hauser None 124216 22. Mrz 18:53 fountain_properties.json
-rwxrwx---+ 1 hauser None 12615 23. Mrz 05:20 locations.json
...
and there is no shared-constants.json ?
Also, there is a
src/app/shared-constants.ts
which probably should go ?

run
~/git/proximap: npm run sync_datablue
